Difficulty

The AWS Certified Solutions Architect - Associate exam's difficulty is significantly influenced by the extensive scope of topics it covers. This wide-ranging content demands a thorough understanding of many AWS services and their integration, which can be daunting, especially for those new to AWS or cloud computing.

 

The exam covers key areas including compute, storage, databases, networking, security, and application architecture. For compute, you need to understand services like EC2, which involves knowledge of instance types, pricing models, and scaling strategies. You must also be familiar with Lambda, which introduces a serverless paradigm that requires a different approach to architecture and deployment compared to traditional server-based models.

 

Storage is another critical domain, with services like S3 and EBS. Understanding S3 includes grasping its storage classes, bucket policies, and lifecycle management, while EBS requires knowledge of volume types, performance characteristics, and backup solutions. Databases on AWS span both relational (RDS) and non-relational (DynamoDB) systems, each with its own configuration, scaling, and maintenance considerations.

 

Networking on AWS involves VPC, subnets, routing tables, and gateways, which are foundational to designing secure and efficient cloud architectures. You must understand how to set up and manage these components to ensure proper isolation, connectivity, and security. Security itself is a vast topic, covering IAM (Identity and Access Management), encryption, and compliance requirements. Mastery of these elements is crucial, as security misconfigurations can lead to vulnerabilities.

 

The application architecture domain requires knowledge of how to design distributed systems that are highly available, fault-tolerant, and scalable. This involves using load balancers, auto-scaling groups, and designing stateless applications. Moreover, understanding the cost implications of architectural decisions is vital for optimizing performance while managing expenses.

The interrelated nature of these topics adds to the complexity. For instance, designing a fault-tolerant application involves not just compute and storage considerations but also networking and security configurations. 

 

Effective preparation for the exam requires an integrated understanding of how these services work together to build robust, efficient, and secure solutions.

The breadth and depth of knowledge required across these domains, coupled with the need to stay updated with AWS’s frequent service updates and enhancements, contribute significantly to the exam's difficulty.

Exam Domains and Tasks - example questions

Explore the domains and tasks of AWS Certified Solutions Architect - Associate - SAA-C03 exam, along with example questions set.

Question

Task 1.1 Design secure access to AWS resources

A company has an on-premise Active Directory (AD) that manages identities for its employees. They have recently begun leveraging AWS for their new cloud-native applications. The security team has specified that the company must maintain a single unified identity management system. They want to ensure that on-premise users can access AWS resources without requiring separate AWS IAM user accounts, and permissions should be managed centrally through AD groups. They will also need to share certain AWS resources within various departments using AWS accounts without replicating resources or compromising security controls. Given these criteria, which solution should the Solutions Architect recommend?

select single answer

Explanation

Federating an on-premise directory service with AWS IAM roles allows users to assume IAM roles based on their AD credentials, eliminating the need to create IAM users for each employee. AWS Resource Access Manager enables the sharing of AWS resources between accounts in a secure manner, which aligns with the requirement to share resources without replicating them or compromising security.

Explanation

Amazon Cognito is primarily used for consumer identity management, not for corporate identity federation with AD. It is also not necessary to migrate the AD identities to AWS, since federation allows the use of existing identities.

Explanation

AWS SSO does allow for identity federation, but the requirement specifically states to manage permissions centrally through AD groups. Furthermore, IAM permissions cannot be directly applied to on-premise user accounts; they must be mapped to IAM roles.

Explanation

The requirement was to maintain a single unified identity management system, not to create separate IAM user accounts. While AWS Organizations is useful for managing policies, it does not address the identity federation requirement.

Question

Task 1.2 Design secure workloads and applications

A company is hosting a high-profile web application on AWS which is expected to attract a large number of international users. The application is architected with an Elastic Load Balancer (ELB) in front of Amazon EC2 instances across multiple Availability Zones. The IT Security Architect wants to ensure that the application is protected against Distributed Denial of Service (DDoS) attacks. Which of the following services should the architect incorporate into the architecture to secure the application's external network connections while providing DDoS protection?

select single answer

Explanation

AWS Shield Advanced provides expanded DDoS protection for AWS services like Elastic Load Balancer, Amazon EC2, Amazon CloudFront, and AWS Global Accelerator. It also integrates with AWS WAF for a more robust security posture. This is appropriate for high-profile applications that require a higher level of protection against sophisticated attacks.

Explanation

While AWS Direct Connect does provide a dedicated connection to AWS, it does not offer DDoS protection. Direct Connect is mainly for reducing network costs, increasing bandwidth throughput, and providing a more consistent network experience.

Explanation

Amazon Inspector is an automated security assessment service that helps improve the security and compliance of applications deployed on AWS, but it does not specifically protect against DDoS attacks. It is primarily used for vulnerability scanning.

Explanation

An IPSec VPN connection would secure data transfers between the AWS cloud and the company's on-premises network, but it does not provide specific protection against DDoS attacks targeting the web application.

Question

Task 1.3 Determine appropriate data security controls

You are designing a secure architecture for your company’s document management system on AWS. The system stores sensitive documents that must be backed up daily and retained for seven years for compliance reasons. The documents are stored on Amazon Elastic Block Store (EBS) volumes attached to EC2 instances. You need to ensure that backups are automated and adhere to the company’s data retention policy. Which of the following would be the MOST efficient solution to automate the backup process while meeting the data retention requirements using Amazon Data Lifecycle Manager?

select single answer

Explanation

Amazon Data Lifecycle Manager allows you to automate the creation, retention, and deletion of snapshots taken to back up your EBS volumes. By setting up a daily schedule for snapshot creation and specifying a retention period of seven years, it ensures compliance with the data retention policy without manual intervention.

Explanation

While AWS Backup can be used for the backups, the question specifies the need for an automated solution, and manually triggering snapshots would not be efficient nor does it ensure compliance with the retention policy.

Explanation

Amazon S3 Lifecycle policies are for managing objects in S3, not for taking EBS snapshots. This option does not directly address the backup of EBS volumes nor the use of Amazon Data Lifecycle Manager.

Explanation

Running a cron job script is a manual approach and less efficient compared to using Amazon Data Lifecycle Manager. Amazon Glacier is for cold storage of data, not for taking EBS volume snapshots, and managing this process via CLI scripts would not be as reliable or compliant as using automation through Amazon Data Lifecycle Manager.

Question

Task 2.1 Design scalable and loosely coupled architectures

A company with an international customer base is running a multi-tier web application on AWS, which includes web servers, application servers, and a MySQL database. The application experiences high latency and traffic congestion due to its global user base. The company's goal is to improve the application's performance and reduce the latency for its users worldwide without making changes to the application code or infrastructure. As an AWS Certified Solutions Architect - Associate, which AWS service would you recommend to reduce latency and improve overall performance by routing user traffic through the AWS global network infrastructure?

select single answer

Explanation

AWS Global Accelerator improves application performance by routing user traffic through AWS's global network infrastructure, reducing latency and improving the user experience. It optimally routes traffic to the nearest application endpoint, even across multiple AWS regions, thus fulfilling the company's requirement without altering the application itself.

Explanation

Although Amazon CloudFront is a content delivery network (CDN) that can reduce latency by caching content at edge locations, it is more suited for static content and is not the best choice for accelerating all traffic types including dynamic content, API calls, or game streaming.

Explanation

AWS Direct Connect is used to establish a dedicated network connection between an on-premises network and AWS. While it can reduce network costs and increase bandwidth throughput, it does not inherently optimize the performance of internet-facing applications for a global audience.

Explanation

Amazon Route 53 is a scalable Domain Name System (DNS) web service that can route users to the infrastructure running in AWS. While Route 53 can be used to route traffic efficiently, it does not provide the same performance benefits in terms of accelerating user traffic on the AWS network as AWS Global Accelerator does.

Question

Task 2.2 Design highly available and/or fault-tolerant architectures

You are a Solutions Architect tasked with improving the reliability of a legacy database application that must remain operational 24/7. This application is currently running on-premises and is not designed for horizontal scaling or redundancy. The company wants to minimize downtime and improve disaster recovery capabilities without making any modifications to the application code. Which of the following strategies would best utilize AWS services to meet these requirements?

select single answer

Explanation

This is correct because AWS DMS can facilitate the replication of data from an on-premises database to AWS without requiring any changes to the application. Using Amazon RDS with Multi-AZ deployment ensures high availability and fault tolerance by automatically provisioning and managing a secondary standby replica of your database in a different Availability Zone (AZ). In case of issues with the primary database, RDS would automatically failover to the standby instance with minimal disruption.

Explanation

Rewriting the application is not an option according to the initial constraints of the question, which specified that application changes are not possible. The focus of this scenario is on improving database reliability without modifying the application.

Explanation

While using Amazon EBS with provisioned IOPS can help improve performance, relying on a single EC2 instance does not provide the required high availability or fault tolerance, as this setup would have a single point of failure.

Explanation

This approach may improve the availability of the application layer by allowing it to scale and distribute traffic, but it does not address the need for database reliability and disaster recovery, as the database would still be a single point of failure on-premises.

Question

Task 3.1 Determine high-performing and/or scalable storage solutions

A company is developing a new web application that will be deployed on AWS. The application requires a shared file system that can automatically scale as the number of application instances increases due to user demand. The file system must also support a POSIX-compliant file system interface to allow their existing on-premises applications to integrate seamlessly without code modifications. Which AWS storage service should the Solutions Architect recommend?

select single answer

Explanation

Amazon EFS is a scalable file storage to use with AWS Cloud services and on-premises resources. It is designed to scale on demand to petabytes without disrupting applications, grow and shrink automatically as you add and remove files, and is POSIX-compliant which makes it suitable for the company's requirements.

Explanation

While Amazon S3 is highly scalable and suitable for a wide range of applications, it is not a POSIX-compliant file system and does not provide a file system interface, which is required for the company's on-premises applications.

Explanation

Amazon FSx for Lustre is a file system service optimized for compute-intensive workloads, such as high-performance computing, machine learning, and media data processing workflows. While it can scale, it's not POSIX-compliant in the same manner as Amazon EFS and may not be suitable for the company's requirement of integrating existing on-premises applications.

Explanation

Amazon EBS provides block level storage volumes for use with EC2 instances but does not offer a shared file system that can be accessed by multiple EC2 instances simultaneously. It is also not designed to automatically scale in the same way as Amazon EFS.

Question

Task 3.2 Design high-performing and elastic compute solutions

A company is hosting a web application on AWS, which experiences predictable traffic patterns. Traffic peaks on the weekends, with very minimal usage during weekdays. The application is currently deployed on a set of t2.large EC2 instances which are underutilized during weekdays resulting in cost inefficiencies. The Solutions Architect has been assigned to optimize this scenario by implementing EC2 Auto Scaling. Which of the following strategies should the Architect recommend to meet the business requirement of cost-saving while maintaining performance?

select single answer

Explanation

Scheduled scaling allows the Architect to increase (scale out) or decrease (scale in) the number of EC2 instances at specific times. This strategy matches the demand pattern of the web application, ensuring performance during peak times and cost savings during off-peak times.

Explanation

Upgrading to larger instances does not address the cost inefficiencies of having underutilized resources during off-peak times. Moreover, it could lead to a higher cost without utilizing the flexibility of Auto Scaling.

Explanation

While Spot Fleets can be cost-effective, they are best suited for fault-tolerant workloads because Spot Instances can be terminated by AWS when the spot price exceeds the bid. Moreover, this does not align with the predictable pattern of workload requiring scaling in and out at specific times.

Explanation

While setting a high CPU utilization threshold for scale-in could reduce the number of instances, this does not guarantee minimized running instances during off-peak times to align with the predictable low traffic pattern during weekdays.

Question

Task 3.4 Determine high-performing and/or scalable network architectures

A company has expanded its operations from a single AWS region to multiple AWS regions around the globe. They require a network infrastructure that allows for secure, efficient, and easy communication between their Amazon Virtual Private Clouds (VPCs) in different regions without the complexity of managing individual VPC peering connections. Additionally, they need the ability to enforce consistent security policies across all VPCs and connect on-premises data centers to their cloud resources. Which AWS service would most appropriately fulfill these business requirements?

select single answer

Explanation

AWS Transit Gateway allows for the connection of multiple VPCs and on-premises networks through a central hub. It simplifies network management and enables you to implement a single network that spans multiple AWS regions. This fits the requirement for secure, easy communication between VPCs and the need to apply uniform security policies.

Explanation

AWS Direct Connect primarily provides a dedicated network connection from on-premises to AWS. While it can offer consistent network performance, it does not inherently provide inter-region VPC connectivity or simplify the management of those connections.

Explanation

AWS VPN enables secure connections between on-premises networks, remote offices, client devices, and the AWS global network. However, it's not optimized for simplifying the connectivity of multiple VPCs across different AWS regions, unlike AWS Transit Gateway.

Explanation

Amazon Route 53 is a highly available and scalable cloud Domain Name System (DNS) web service. It is not designed to establish and manage connectivity across VPCs and regions, which is the primary requirement of the scenario described.

Question

Task 3.5 Determine high-performing data ingestion and transformation solutions

A Solutions Architect is designing a data lake solution where numerous CSV files are frequently uploaded to an Amazon S3 bucket. The data analytics team has requested to have these files converted to the Parquet format for more efficient querying with Amazon Athena. The data must be transformed automatically upon upload, with minimal development effort. Which AWS service should the architect use to meet these requirements?

select single answer

Explanation

AWS Glue is a fully managed extract, transform, and load (ETL) service that makes it easy to prepare and load data for analytics. It can automatically convert data from one format to another (e.g., from CSV to Parquet) and handle schema evolution. Glue can be triggered by Amazon S3 events, making it suitable for this scenario.

Explanation

While Amazon Kinesis Firehose can convert incoming stream data into different formats and load it into Amazon S3, it is primarily used for real-time streaming data rather than handling file-based uploads like those described in the scenario.

Explanation

Amazon Relational Database Service (RDS) is a database service that allows you to operate relational databases in AWS. It does not handle file transformations from S3 buckets; it is not suitable for the file conversion requirement described.

Explanation

AWS Data Pipeline is a web service that helps you automate the movement and transformation of data. However, it is more heavyweight compared to AWS Glue for this use case and would require more development effort for such a simple transformation.

Question

Task 4.1 Design cost-optimized storage solutions

A company has recently transitioned to AWS, but still maintains a significant amount of on-premises data, generating about 1 TB of new data each month. This data is rarely accessed, but must be preserved for regulatory reasons. The company needs a cost-effective solution that allows them to store their on-premises backup data on AWS, while ensuring that the data is readily accessible when needed for compliance. Which AWS service should they use to meet these requirements?

select single answer

Explanation

AWS Storage Gateway's File Gateway configuration allows the organization to store and access files in S3 as they would on-premises storage, which is cost-effective because it takes advantage of the low cost of S3 storage and lifecycle policies to automatically transfer data to S3 Glacier or S3 Glacier Deep Archive for even more cost savings on infrequently accessed items.

Explanation

EBS Cold HDD (sc1) volumes are designed for less frequently accessed workloads, but they are not suitable for backup data that needs to be stored cost-effectively on the cloud; they are primarily used for certain types of workloads on EC2 instances.

Explanation

Provisioned IOPS SSD (io1) volumes are designed for high-performance database workloads, not for cost-effective backup storage solutions, making them an expensive choice for infrequently accessed data.

Explanation

While AWS S3 Intelligent-Tiering could be cost-effective by automatically moving data to the most cost-effective access tier, it doesn't address the requirement of connecting on-premises data to AWS. AWS Storage Gateway is more suitable for simplified storage management and easy integration of on-premises with AWS.

Question

Task 4.2 Design cost-optimized compute solutions

A company is running a memory-intensive application on Amazon EC2 instances and has recognized a consistent compute usage pattern over a long period. The application requires instances with high memory to compute ratio and predictable performance. The company would like to reduce their AWS bill and is considering EC2 Savings Plans. Which EC2 instance family should the company choose to optimize costs while selecting an EC2 Savings Plans for their workload?

select single answer

Explanation

The correct answer is the R instance family because these instances are optimized for memory-intensive workloads. They offer more memory compared to other EC2 instance families, which matches the requirements of the company's application. By choosing EC2 Savings Plans with R instances, the company can commit to consistent usage and benefit from a lower hourly rate, resulting in cost savings.

Explanation

The C instance family is optimized for compute-intensive workloads, not memory-intensive ones, so while they offer high CPU performance, they may not provide the best memory to compute ratio for the company's application needs.

Explanation

P instance family is optimized for graphics and general-purpose GPU compute workloads. These instances are not tailored for memory-intensive applications, so while they offer powerful GPU capabilities, they wouldn't be cost-effective for this specific memory-intensive workload.

Explanation

The T instance family is designed for general-purpose workloads with inconsistent CPU usage that is lightweight or sporadic. They offer the ability to burst in performance. This does not align well with the memory-intensive, consistent usage pattern of the company's application.

Question

Task 4.3 Design cost-optimized database solutions

A company is collecting time-series data from thousands of IoT sensors distributed globally. The data consists of high volume temperature and humidity readings recorded every minute. The company needs a cost-effective database service that can handle the high ingestion rates and provide fast, scalable queries for real-time analytics. Which AWS database service would be most cost-effective and appropriate for this use case?

select single answer

Explanation

Amazon Timestream is a serverless, scalable time-series database service built specifically to handle high volume and velocity data found in IoT and operational applications. It is designed for real-time analytics, which makes it a good fit for the described scenario and can be cost-effective as it requires no servers to manage and it's optimized for time-series data.

Explanation

While Amazon RDS is a robust relational database service, it is not specifically optimized for time-series data. It may not handle the high ingestion rates as efficiently as Timestream, and could potentially be more expensive to scale for this particular use case.

Explanation

Amazon DynamoDB is a NoSQL database service that offers quick performance with scalability. However, it may not be the most cost-effective option for time-series data as it is not specifically tailored for this type of workload and might require extensive design patterns to handle time-series data efficiently.

Explanation

Amazon Redshift is a data warehouse service that is excellent for complex queries and analytics on large datasets. However, it is not optimized for high velocity, fine-grained time-series data typical for IoT scenarios and might incur higher costs compared to a service designed specifically for time-series data.
