Difficulty

The AWS Certified Advanced Networking - Specialty (ANS-C01) certification is a highly specialized credential aimed at professionals with advanced networking skills and extensive experience in designing and implementing AWS and hybrid IT network architectures at scale. The exam tests a deep understanding of a broad range of AWS networking services and concepts, along with the ability to design, develop, and deploy complex cloud-based solutions using the Amazon Web Services platform.

 

A significant portion of the exam focuses on networking fundamentals and concepts, requiring candidates to have a strong grasp of the OSI model and how various networking protocols map to it. Understanding IP addressing, particularly in IPv4 and IPv6, is crucial, including subnetting, CIDR (Classless Inter-Domain Routing), and the differences between these IP versions. Additionally, knowledge of routing and switching is vital, with an emphasis on static and dynamic routing protocols such as RIP, OSPF, and BGP, as well as concepts like route tables, network address translation (NAT), and switching mechanisms.

 

The exam extensively covers AWS networking services, beginning with Amazon VPC (Virtual Private Cloud), a core service that allows the creation of isolated networks within AWS. Candidates are expected to understand VPC components, including subnets, route tables, security groups, and Network ACLs (NACLs). Additionally, the exam delves into more advanced VPC features like VPC Peering, Transit Gateway, and VPC endpoints. AWS Direct Connect is another critical service, providing a dedicated network connection from an on-premises environment to AWS, and the exam assesses knowledge of its setup, configuration, and use cases.

 

AWS VPN is also a key service, with the exam focusing on both Site-to-Site VPN and Client VPN, including setup, encryption standards, and integration with VPCs and on-premises networks. Elastic Load Balancing (ELB) is another important topic, where candidates must have detailed knowledge of application, network, and gateway load balancers, including their use cases and configuration. The exam also evaluates understanding of AWS Global Accelerator, which is used to improve global application performance by leveraging AWS’s global network infrastructure.

 

Amazon Route 53, AWS’s DNS service, plays a significant role in the exam, with candidates needing to demonstrate knowledge of routing policies such as latency-based, geolocation, and failover, as well as domain registration and health checks. AWS Transit Gateway, which allows the interconnection of VPCs and on-premises networks via a central hub, is another critical topic, including concepts like route propagation, attachments, and segmentation. Amazon CloudFront, a content delivery network (CDN) service, is also covered, with a focus on edge locations, distribution types, and caching strategies.

 

Security is a major theme in the exam, with an emphasis on securing AWS networking components using security groups, NACLs, AWS Web Application Firewall (WAF), and Shield (DDoS protection). Candidates must also understand encryption, both in-transit and at-rest, as well as AWS compliance frameworks like PCI DSS, HIPAA, and GDPR, and how they impact network design. Disaster recovery and high availability strategies are also tested, including Multi-AZ and Multi-Region architectures, failover mechanisms, and data replication to ensure network resilience and data redundancy.

 

The exam also tests knowledge of network automation and monitoring. Candidates need to be proficient in using AWS CloudFormation, AWS CLI, and SDKs for automating network deployments, as well as third-party automation tools like Terraform. Monitoring and troubleshooting are equally important, with expertise in using Amazon CloudWatch, VPC Flow Logs, AWS Config, and AWS CloudTrail to monitor, troubleshoot, and audit network activity. The exam may present scenarios requiring the identification and resolution of network performance issues.

 

Hybrid networking and multi-account environments are also key areas of focus. Candidates must understand hybrid cloud architectures, including connecting on-premises networks with AWS using services like AWS Direct Connect and VPN. The exam also includes scenarios involving multiple AWS accounts, VPC peering, and shared services, and requires knowledge of AWS Organizations and best practices for managing networking across multiple AWS accounts, including the use of centralized logging and monitoring, shared VPCs, and resource access management.

 

The AWS Certified Advanced Networking - Specialty (ANS-C01) exam is known for its difficulty. It requires a deep understanding of AWS networking services and the ability to apply this knowledge to complex, real-world scenarios. The depth of knowledge required is significant, with the exam testing advanced networking concepts that go beyond basic AWS networking. The questions are often scenario-based, requiring candidates to design or troubleshoot a network architecture, which tests both knowledge and problem-solving skills. The breadth of services covered is also extensive, requiring candidates to understand how different AWS services integrate with each other, adding to the challenge. Additionally, the time pressure of the exam, with its detailed and time-consuming questions, makes effective time management crucial.

 

Overall, the AWS Certified Advanced Networking - Specialty (ANS-C01) certification is an excellent credential for professionals seeking to demonstrate their expertise in AWS networking. It validates a candidate’s ability to design, deploy, and maintain complex network architectures on AWS, making it a valuable certification for network engineers, architects, and systems administrators. However, due to its difficulty, it requires thorough preparation and substantial practical experience with AWS networking services.

Question

Task 1.1 Design a solution that incorporates edge network services to optimize user performance and traffic management for global architectures

Your company is expanding its customer base globally and needs to ensure that users from different regions have optimal performance when accessing your web application. You currently use Elastic Load Balancing (ELB) to distribute traffic among your application servers. To further improve performance and traffic management, you are considering integrating additional AWS services. Which solution would best suit this requirement?

select single answer

Explanation

While deploying additional ALBs in each region can help distribute the traffic more efficiently, it requires more complex management and does not leverage global edge networks for caching content.

Explanation

Auto Scaling with spot instances can help with cost management and scaling based on load but does not directly help with optimizing content delivery for a global audience.

Explanation

Amazon CloudFront is a Content Delivery Network (CDN) that works seamlessly with ELB to cache content close to the users and reduces latency, improving performance for a global audience.

Explanation

While Amazon Route 53 with latency-based routing can route users to the closest region, it does not cache content like CloudFront, so it doesn't optimize performance in the same way.

Question

Task 1.2 Design DNS solutions that meet public, private, and hybrid requirements

You are working as a network architect for a company that has recently migrated its web applications to AWS. They are aiming to improve the performance and security of their global web traffic. The company has registered its domain through Amazon Route 53 and is using Amazon CloudFront as a Content Delivery Network (CDN) to cache and serve their web content closer to end-users across the globe. They want to make sure that the DNS records are optimally configured to integrate with CloudFront, ensuring both availability and security. Which DNS configuration should you choose in Route 53 to best meet these requirements?

select single answer

Explanation

TXT records are typically used for arbitrary text data, such as verification information for domain ownership or email sender policies. They do not play any role in routing web traffic to a CloudFront distribution.

Explanation

An MX record is used for directing mail servers and is irrelevant to web traffic and CDN integration. Using an MX record here would not help in routing web requests to CloudFront.

Explanation

Using an 'A' record with an alias to the CloudFront distribution domain provides the benefit of an edge-optimized service, reducing latency and improving load times while also maintaining Route 53's DNS failover and health check features.

Explanation

While a CNAME record could technically work, it is not as efficient as an 'A' record with aliasing in Route 53. A CNAME cannot be used at the root domain level and lacks some of the advanced features provided by Route 53 when A records are used, such as DNS failover and health checks.

Question

Task 1.3 Design solutions that integrate load balancing to meet high availability, scalability, and security requirements

Your company has an e-commerce application hosted on a fleet of EC2 instances in a multi-AZ architecture. It has been reported that the application occasionally experiences high latency during peak traffic times. To address this issue, your manager asks you to design a solution that ensures high availability and scalability. You decide to integrate an AWS Network Load Balancer (NLB) into the architecture. Considering the need for high availability, scalability, and security, which of the following configurations is the most appropriate? 1. Associate the NLB with a target group that contains the existing EC2 instances. 2. Enable cross-zone load balancing in the NLB settings. 3. Ensure that health checks are configured to monitor the application endpoints. 4. Use an Auto Scaling Group to dynamically adjust the number of EC2 instances based on traffic. Which of the following steps should NOT be included in your design?

select single answer

Explanation

Configuring health checks is essential for ensuring that traffic is only routed to healthy instances, thus maintaining high availability.

Explanation

An Auto Scaling Group is crucial for automatically adjusting the number of instances in response to traffic demand, ensuring scalability and availability.

Explanation

Network Load Balancers do not support cross-zone load balancing natively. Enabling cross-zone load balancing is more relevant for Application Load Balancers (ALBs). For NLB, traffic is distributed per Availability Zone.

Explanation

Associating the NLB with a target group containing the existing EC2 instances is necessary to ensure that traffic is properly distributed among the instances.

Question

Task 1.4 Define logging and monitoring requirements across AWS and hybrid networks

You have been tasked with designing a network monitoring and logging solution for a hybrid cloud architecture that spans both AWS and on-premises resources. Your organization is keen to capture baseline network performance metrics for their AWS resources and requires real-time insights to identify potential bottlenecks. Which AWS service would you use to achieve this, and how would you implement it considering the need to monitor both AWS and hybrid networks?

select single answer

Explanation

AWS X-Ray is used for distributed tracing of requests across microservices and is primarily focused on application-level monitoring rather than network performance metrics. It does not provide the comprehensive network monitoring and logging required for capturing baseline network performance.

Explanation

Amazon CloudWatch is designed to monitor AWS resources and applications and can be extended to include on-premises resources using the CloudWatch Agent. It provides robust performance metrics, dashboards, and the ability to set alarms and visualize data, which is essential for capturing baseline network performance.

Explanation

Amazon Inspector is a security assessment service that inspects AWS resources for vulnerabilities and deviations from best practices. It is not designed for ongoing performance monitoring or logging of network metrics.

Explanation

AWS CloudTrail is primarily used for auditing API calls and user activity rather than capturing network performance metrics. It records AWS API requests and does not provide performance monitoring or logging functionality.

Question

Task 1.5 Design a routing strategy and connectivity architecture between on-premises networks and the AWS Cloud

A large enterprise is looking to expand its network infrastructure to the AWS Cloud using a software-defined wide area network (SD-WAN) approach. They currently have an on-premises data center with several branch offices connected through an MPLS network. They want to leverage AWS services to provide reliable, secure, and scalable connectivity between their on-premises network and their VPCs in AWS. They are considering using AWS Transit Gateway and AWS VPN in combination with their SD-WAN for optimal performance. Given these requirements, which architecture should they implement?

select single answer

Explanation

While technically possible, this solution is not scalable or efficient for a large enterprise with numerous branch offices. Managing multiple VPN connections directly to VPCs can become complex and cumbersome.

Explanation

While feasible, this solution does not leverage the benefits of SD-WAN integration and reduces the overall efficiency and flexibility in managing traffic between branch offices and AWS. It would also place additional load on the on-premises data center.

Explanation

AWS Direct Connect is generally more suitable for high-bandwidth and low-latency requirements but would be cost-prohibitive and complex to manage for numerous branch offices distributed geographically.

Explanation

This approach leverages the AWS Transit Gateway with Transit Gateway Connect, providing a scalable and reliable way to integrate SD-WAN connections with the AWS environment. The use of VPN attachments ensures secure connectivity from the branch offices to the Transit Gateway, facilitating optimal routing to VPCs.

Question

Task 1.6 Design a routing strategy and connectivity architecture that include multiple AWS accounts, AWS Regions, and VPCs to support different connectivity patterns

As a senior network architect for a growing company, you've been tasked with designing a routing strategy and connectivity architecture that connects multiple AWS accounts, AWS regions, and VPCs. During the planning phase, you realize that there are IP address overlaps between different VPCs in different AWS accounts. You need to ensure seamless connectivity across these VPCs without conflicts. Which service and setup would be the most appropriate to manage these IP overlaps effectively?

select single answer

Explanation

AWS Direct Connect provides dedicated network connections to AWS but does not inherently resolve IP address overlaps between VPCs. It's primarily for establishing high-bandwidth, low-latency connectivity rather than addressing overlapping IP concerns.

Explanation

While VPC Peering allows routing between VPCs, it does not handle IP address overlaps. Peering does not provide NAT capabilities to manage overlapping CIDR blocks, leading to potential IP address conflicts.

Explanation

AWS Transit Gateway can act as a central hub for interconnecting multiple VPCs across accounts and regions. By using NAT with the Transit Gateway, you can translate IP addresses and resolve conflicts arising from IP overlaps.

Explanation

AWS PrivateLink enables access to services through private IP addresses within VPCs but does not facilitate general routing and NAT for managing IP overlaps. It is more suited for exposing services privately rather than managing complex VPC-to-VPC connectivity with overlapping IPs.

Question

Task 2.1 Implement routing and connectivity between on-premises networks and the AWS Cloud

Your company, ABC Corp, has recently deployed an AWS Direct Connect connection between its on-premises data center and its VPC in AWS. As part of the implementation phase, you need to test and validate the connectivity between these environments. However, you realize that the on-premises network cannot reach your resources in the VPC. Which of the following steps should you take to identify and resolve the connectivity issue?

select single answer

Explanation

IAM roles are not involved in the establishment or management of the AWS Direct Connect link. This option does not address the core issues of network routing or connectivity.

Explanation

SSL certificates are used for secure communication but are not related to establishing basic connectivity or routing between the on-premises network and the VPC.

Explanation

If the BGP (Border Gateway Protocol) session is not established or routes are not correctly advertised, the on-premises environment will not be able to reach resources in the VPC. Ensuring the BGP session is up and routes are correct is crucial for connectivity.

Explanation

While quotas can limit network capacity, exceeding a quota typically affects throughput rather than completely blocking connectivity. The issue described is more likely related to routing or session establishment rather than quota limits.

Question

Task 2.2 Implement routing and connectivity across multiple AWS accounts, Regions, and VPCs to support different connectivity patterns

You are a network engineer for a multinational company that has a complex AWS environment with multiple AWS accounts, Regions, and Virtual Private Clouds (VPCs). Your company is using AWS Transit Gateway to facilitate the network connectivity among different VPCs. Recently, the security team has requested enhanced network monitoring and logging to ensure compliance with regulatory requirements and to identify any potential security threats. Which of the following solutions should you implement to achieve robust network monitoring and logging for your AWS Transit Gateway setup?

select single answer

Explanation

AWS CloudTrail is primarily used for logging API calls made in your AWS account but it does not log network traffic directly. Setting up SNS notifications for API calls won't provide the required network monitoring and logging capabilities.

Explanation

While AWS Direct Connect can provide a dedicated connection from your premises to AWS, it does not inherently provide network monitoring and logging capabilities. You would still need a solution like VPC Flow Logs for detailed network traffic monitoring.

Explanation

Enabling VPC Flow Logs for each VPC connected to the Transit Gateway allows you to capture detailed information about the IP traffic going to and from network interfaces in your VPCs. Integrating these logs with Amazon CloudWatch Logs enables robust monitoring and the ability to perform traffic analysis.

Explanation

AWS Config tracks configuration changes to AWS resources but it does not provide detailed network traffic monitoring and logging. It’s useful for auditing AWS configurations but not for analyzing network traffic.

Question

Task 2.3 Implement complex hybrid and multi-account DNS architectures

You are managing a multi-account AWS environment and need to configure DNS monitoring and logging for a hybrid architecture involving Amazon Route 53 and Amazon VPCs. Your architecture includes a primary on-premises data center connected to your AWS environment via Direct Connect. You aim to log all DNS queries that originate from both the on-premises and AWS VPC environments for security and troubleshooting purposes. What is the BEST approach to achieve comprehensive DNS query logging in this scenario?

select single answer

Explanation

While this approach may capture DNS logs within the VPC, it would not automatically cover DNS queries originating from the on-premises data center or between VPCs without additional complex routing and logging configurations.

Explanation

Enabling Route 53 Resolver query logging will capture DNS queries that pass through Route 53, including those from on-premises via Direct Connect. VPC Flow Logs can log network traffic, including DNS queries within the VPCs.

Explanation

AWS Config is used to track configuration changes and compliance but does not have the capability to log individual DNS queries.

Explanation

AWS CloudTrail primarily logs API calls and is not designed for logging DNS queries. It can provide some information on DNS-related API activities but not the DNS queries themselves.

Question

Task 2.4 Automate and configure network infrastructure

John, a network engineer at a growing tech company, is tasked with optimizing the cloud network resources using Infrastructure as Code (IaC). He needs to automate the configuration of AWS networking components such as VPC, subnets, and security groups. John decides to use Terraform for this purpose. How should John proceed with automating the creation and management of these AWS resources using Terraform?

select single answer

Explanation

AWS CloudFormation is another IaC service but it's not the one John decided to use. The question explicitly states John is using Terraform.

Explanation

Terraform configuration files (written in HashiCorp Configuration Language - HCL) allow you to define infrastructure resources declaratively. The 'terraform apply' command will then execute these configurations, creating and managing the specified AWS resources as defined.

Explanation

This approach is not in line with the idea of automating the resource management process with IaC. Terraform is used to automate the deployment, not just to manage existing manually created resources.

Explanation

'terraform import' is used to import existing resources into Terraform management, not to automate new resource creation. For a new infrastructure setup, the 'terraform apply' command should be used to create resources based on configuration files.

Question

Task 3.1 Maintain routing and connectivity on AWS and hybrid networks

Your company has a hybrid network infrastructure onboard AWS leveraging a Transit Gateway to interconnect multiple VPCs and on-premises data centers. You're tasked with optimizing the routing configurations to enhance network performance. Currently, different static and dynamic routing protocols are used throughout the network setup. However, the internal networking team has noticed overlapping CIDR blocks affecting existing route summarizations. What should you do to optimize the routing in your AWS environment while handling the CIDR overlap?

select single answer

Explanation

Disabling static routing protocols and relying entirely on default routes ignores the complexity and specifics of route management and does not address the CIDR overlap issue.

Explanation

Consolidating overlapping CIDR blocks and reconfiguring the Transit Gateway route table helps to resolve conflicts and allows for proper route summarization, improving the overall routing efficiency in your hybrid network.

Explanation

Dynamic routing protocols like BGP can handle some aspects of route changes but will not resolve CIDR overlap issues by themselves. Configuration adjustments at the route table level are also necessary.

Explanation

Adding more specific routes without correcting the CIDR conflicts can lead to more complexity and potential routing issues rather than optimizing the routing and solving the overlap problem.

Question

Task 3.2 Monitor and analyze network traffic to troubleshoot and optimize connectivity patterns

You are a network engineer responsible for managing an Amazon VPC that supports a critical application. Your application is experiencing intermittent connectivity issues when communicating with an on-premises data center over a VPN. You suspect there might be a problem with packet size mismatches. How would you identify and resolve this issue to restore network connectivity?

select single answer

Explanation

Security group settings manage access and permissions but do not resolve packet size mismatch problems.

Explanation

Redeploying the VPC resources does not address the specific issue of packet size mismatches.

Explanation

VPC Flow Logs will help you identify any dropped packets or issues related to packet sizes. Adjusting the MTU settings can ensure compatibility between the VPC and the on-premises network.

Explanation

While AWS Direct Connect can offer more stable and consistent connectivity than a VPN, it does not directly address packet size mismatch issues.

Question

Task 3.3 Optimize AWS networks for performance, reliability, and cost- effectiveness

You are a network engineer for a global media streaming company that aims to optimize its content delivery network (CDN) to enhance performance and availability. Your company currently uses AWS Direct Connect for a dedicated network connection from your on-premises data center to AWS. However, users in different regions report varying network performance. To improve the latency and availability of your streaming services, you decide to implement AWS Global Accelerator. What combination of AWS services and configurations would best optimize network connectivity for your users?

select single answer

Explanation

While using a VPN could reduce costs, it would not provide the dedicated bandwidth and low latency of AWS Direct Connect, leading to potential performance issues, especially for a high-demand service like media streaming.

Explanation

AWS Global Accelerator uses static IP addresses and optimizes routing to the closest edge location, reducing latency and improving availability. Combining this with AWS Direct Connect ensures dedicated, low-latency connections, providing an overall optimized network performance.

Explanation

AWS Global Accelerator is designed to improve internet traffic across global regions. Using it only for intra-region traffic limits its potential, as combining it with AWS Direct Connect for both intra and inter-region traffic optimizes performance and availability most effectively.

Explanation

While AWS Global Accelerator significantly improves availability and optimizes routing, discontinuing AWS Direct Connect would remove the low-latency, dedicated connection to AWS, which could negatively impact performance.

Question

Task 4.1 Implement and maintain network features to meet security and compliance needs and requirements

Jane is a DevOps engineer at a FinTech company. Recently, her team has been tasked with improving the security incident reporting and alerting mechanisms to ensure they meet strict compliance requirements for financial services. They want to ensure any configuration changes in their network environment that could impact security are automatically detected and reported. They decide to use AWS Config for this purpose. Which of the following steps should Jane take to achieve this goal?

select single answer

Explanation

AWS WAF is designed to monitor and block web application threats but does not cover comprehensive network configuration monitoring. Its integration with AWS Config wouldn't provide a holistic approach to security incident reporting and alerting for configuration changes.

Explanation

AWS Config rules allow you to monitor AWS resource configurations according to your security compliance policies. Amazon SNS can be used to send notifications and alerts when these rules are breached, ensuring that the security team is immediately informed of any issues.

Explanation

AWS Shield Advanced is specifically for DDoS protection and doesn't address configuration monitoring. Moreover, compliance snapshots do not provide real-time alerting, which is crucial for immediate incident response.

Explanation

While AWS CloudTrail logs can be used to track changes, manually creating reports does not provide real-time alerting and lacks automation, which is essential for rapid incident response.

Question

Task 4.2 Validate and audit security by using network monitoring and logging services

You have recently taken on the role of Network Architect at a mid-sized company utilizing AWS. The company has several AWS accounts and wants to implement a network audit strategy to validate and audit security group configurations. During an audit, it was discovered that some instances have overly permissive security group rules that allow inbound traffic from any IP address. Your task is to ensure that all security groups are as restrictive as possible while still allowing necessary traffic. Which of the following AWS tools or approaches would best help you automate the process of identifying and remediating overly permissive security group rules across multiple accounts and VPCs?

select single answer

Explanation

AWS Firewall Manager is a security management tool that can be used to centrally configure and manage firewall rules across multiple accounts and VPCs. It enables you to enforce a single set of security policies across your organization.

Explanation

AWS CloudTrail captures API calls and activity on your account but is not primarily designed to manage or automate the remediation of security group rules.

Explanation

AWS Trusted Advisor offers recommendations to optimize your AWS environment, including security settings. However, it does not provide automation for correcting overly permissive security groups across multiple accounts.

Explanation

AWS Config can monitor and provide compliance reports regarding your security groups. However, it does not natively provide automated remediation capabilities across multiple accounts.

Question

Task 4.3 Implement and maintain confidentiality of data and communications of the network

You are an AWS Certified Advanced Networking Specialist tasked with enhancing the security of a client's web application. Your client has expressed concerns about the privacy and integrity of DNS queries generated by their application. They are also worried about potential web exploits and malicious traffic targeting their service. You decide to implement secure DNS communications alongside other security measures. Which configuration steps should you take to achieve these objectives using AWS WAF and DNS security protocols?

select single answer

Explanation

DNSSEC secures DNS queries by preventing DNS spoofing but does not encrypt DNS traffic. AWS Shield provides DDoS protection but does not filter HTTP/HTTPS requests or protect against web application vulnerabilities.

Explanation

While CloudFront and AWS WAF together provide comprehensive protection at the application layer and edge locations, they do not specifically address the privacy and integrity of DNS queries.

Explanation

Combining DNS over HTTPS (DoH) or DNS over TLS (DoT) for securing DNS queries ensures privacy and integrity of DNS traffic. AWS WAF provides protection against common web exploits and malicious traffic, safeguarding the web application.

Explanation

While AWS WAF is essential for protection against application layer threats, it does not address the confidentiality and integrity of DNS communications.
