Difference between the SAA-C02 and SAA-C03 AWS Certified Solutions Architect Associate Exam Versions

Before you start preparing for the exam, you have to know the exact knowledge areas and topics that you should focus on. It is also beneficial for you to learn the differences between the previous SAA-C02 version and the new SAA-C03 AWS Certified Solutions Architect Associate certification exam.

Both exam domains of the SAA-C02 and SAA-C03 are virtually the same. As you can see in the diagram below, the new SAA-C03 exam has retained the Design Resilient Architectures, Design High-Performing Architectures, and Design Cost-Optimized Architectures exam domains from the previous one. However, the existing Design Secure Applications and Architectures exam domain was renamed to Design Secure Architectures.

SAA-C02 vs SAA-C03 Comparison AWS Solutions Architect Associate 2022

Another important thing to note here is the change in the percentage of its exam domain coverage. The previous version of the AWS Certified Solutions Architect Associate exam was focused on the topic of resiliency since the Design Resilient Architectures exam domain has the largest exam coverage percentage; compromising 30% of the exam compared with other domains. This time, the new AWS Certified Solutions Architect Associate SAA-c03 exam version has put a spotlight on security. Its biggest exam domain is Design Secure Architecture (30%) so you have to focus on the various security services in AWS as well as the different security features available on each related AWS service.

AWS Certified Solutions Architect Associate Practice Exam SAA-C02 SAA-C03

Sample SAA-C03 Practice Test Questions

Question 1

A company hosted an e-commerce website on an Auto Scaling group of EC2 instances behind an Application Load Balancer. The Solutions Architect noticed that the website is receiving a large number of illegitimate external requests from multiple systems with IP addresses that constantly change. To resolve the performance issues, the Solutions Architect must implement a solution that would block the illegitimate requests with minimal impact on legitimate traffic.

Which of the following options fulfills this requirement?

  1. Create a regular rule in AWS WAF and associate the web ACL to an Application Load Balancer.
  2. Create a custom network ACL and associate it with the subnet of the Application Load Balancer to block the offending requests.
  3. Create a rate-based rule in AWS WAF and associate the web ACL to an Application Load Balancer.
  4. Create a custom rule in the security group of the Application Load Balancer to block the offending requests.

Correct Answer: 3

AWS WAF is tightly integrated with Amazon CloudFront, the Application Load Balancer (ALB), Amazon API Gateway, and AWS AppSync – services that AWS customers commonly use to deliver content for their websites and applications. When you use AWS WAF on Amazon CloudFront, your rules run in all AWS Edge Locations, located around the world close to your end-users. This means security doesn’t come at the expense of performance. Blocked requests are stopped before they reach your web servers. When you use AWS WAF on regional services, such as Application Load Balancer, Amazon API Gateway, and AWS AppSync, your rules run in the region and can be used to protect Internet-facing resources as well as internal resources.

A rate-based rule tracks the rate of requests for each originating IP address and triggers the rule action on IPs with rates that go over a limit. You set the limit as the number of requests per 5-minute time span. You can use this type of rule to put a temporary block on requests from an IP address that’s sending excessive requests.

Based on the given scenario, the requirement is to limit the number of requests from the illegitimate requests without affecting the genuine requests. To accomplish this requirement, you can use AWS WAF web ACL. There are two types of rules in creating your own web ACL rule: regular and rate-based rules. You need to select the latter to add a rate limit to your web ACL. After creating the web ACL, you can associate it with ALB. When the rule action triggers, AWS WAF applies the action to additional requests from the IP address until the request rate falls below the limit.

Hence, the correct answer is: Create a rate-based rule in AWS WAF and associate the web ACL to an Application Load Balancer.

The option that says: Create a regular rule in AWS WAF and associate the web ACL to an Application Load Balancer is incorrect because a regular rule only matches the statement defined in the rule. If you need to add a rate limit to your rule, you should create a rate-based rule.

The option that says: Create a custom network ACL and associate it with the subnet of the Application Load Balancer to block the offending requests is incorrect. Although NACLs can help you block incoming traffic, this option wouldn’t be able to limit the number of requests from a single IP address that is dynamically changing.

The option that says: Create a custom rule in the security group of the Application Load Balancer to block the offending requests is incorrect because the security group can only allow incoming traffic. Remember that you can’t deny traffic using security groups. In addition, it is not capable of limiting the rate of traffic to your application unlike AWS WAF.

Question 2

An AI-powered Forex trading application consumes thousands of data sets to train its machine learning model. The application’s workload requires a high-performance, parallel hot storage to process the training datasets concurrently. It also needs cost-effective cold storage to archive those datasets that yield low profit.

Which of the following Amazon storage services should the developer use?

  1. Use Amazon FSx For Lustre and Amazon EBS Provisioned IOPS SSD (io1) volumes for hot and cold storage respectively.
  2. Use Amazon FSx For Lustre and Amazon S3 for hot and cold storage respectively.
  3. Use Amazon Elastic File System and Amazon S3 for hot and cold storage respectively.
  4. Use Amazon FSx For Windows File Server and Amazon S3 for hot and cold storage respectively.

Correct Answer: 2

Hot storage refers to the storage that keeps frequently accessed data (hot data). Warm storage refers to the storage that keeps less frequently accessed data (warm data). Cold storage refers to the storage that keeps rarely accessed data (cold data). In terms of pricing, the colder the data, the cheaper it is to store, and the costlier it is to access when needed.

Amazon FSx For Lustre is a high-performance file system for fast processing of workloads. Lustre is a popular open-source parallel file system which stores data across multiple network file servers to maximize performance and reduce bottlenecks.

Amazon FSx for Windows File Server is a fully managed Microsoft Windows file system with full support for the SMB protocol, Windows NTFS, Microsoft Active Directory (AD) Integration.

Amazon Elastic File System is a fully-managed file storage service that makes it easy to set up and scale file storage in the Amazon Cloud. 

Amazon S3 is an object storage service that offers industry-leading scalability, data availability, security, and performance. S3 offers different storage tiers for different use cases (frequently accessed data, infrequently accessed data, and rarely accessed data).

 The question has two requirements:

  1. High-performance, parallel hot storage to process the training datasets concurrently.
  2. Cost-effective cold storage to keep the archived datasets that are accessed infrequently

In this case, we can use Amazon FSx For Lustre for the first requirement, as it provides a high-performance, parallel file system for hot data. On the second requirement, we can use Amazon S3 for storing cold data. Amazon S3 supports a cold storage system via Amazon S3 Glacier / Glacier Deep Archive.

Hence, the correct answer is: Use Amazon FSx For Lustre and Amazon S3 for hot and cold storage respectively.

Using Amazon FSx For Lustre and Amazon EBS Provisioned IOPS SSD (io1) volumes for hot and cold storage respectively is incorrect because the Provisioned IOPS SSD (io1) volumes are designed for storing hot data (data that are frequently accessed) used in I/O-intensive workloads. EBS has a storage option called “Cold HDD,” but due to its price, it is not ideal for data archiving. EBS Cold HDD is much more expensive than Amazon S3 Glacier / Glacier Deep Archive and is often utilized in applications where sequential cold data is read less frequently.

Using Amazon Elastic File System and Amazon S3 for hot and cold storage respectively is incorrect. Although EFS supports concurrent access to data, it does not have the high-performance ability that is required for machine learning workloads.

Using Amazon FSx For Windows File Server and Amazon S3 for hot and cold storage respectively is incorrect because Amazon FSx For Windows File Server does not have a parallel file system, unlike Lustre.

Some Notes Regarding Your SAA-C03 exam

The AWS Solutions Architect Associate (SAA-C03) exam loves to end questions that ask for highly available or cost-effective solutions. Be sure to understand the choices provided to you, and verify that they have the correct details. Some choices are very misleading such that it seems it is the most appropriate answer to the question but contains an incorrect detail about some services. 

When unsure of which options are correct in a multi-select question, try to eliminate some of the choices that you believe are false. This will help narrow down the feasible answers to that question. The same goes for multiple choice type questions. Be extra careful as well when selecting the number of answers you submit. Check out the tips mentioned in this article for more information.

As mentioned in this review, you should be able to differentiate services that belong in one category with another. Common comparisons include:

  • EC2 vs ECS vs Lambda
  • S3 vs EBS vs EFS
  • CloudFormation vs OpsWorks vs Elastic Beanstalk
  • SQS vs SNS vs SES vs MQ
  • Security Group vs nACLs
  • The different S3 storage types vs Glacier
  • RDS vs DynamoDB vs Elasticache
  • RDS engines vs Aurora

The Tutorials Dojo Comparison of AWS Services contains excellent cheat sheets comparing these seemingly similar services which are crucial to solving the tricky scenario-based questions in the actual exam. By knowing each service’s capabilities and use cases, you can consider these types of questions already half-solved.

Lastly, be on the lookout for “key terms” that will help you realize the answer faster. Words such as millisecond latency, serverless, managed, highly available, most cost-effective, fault-tolerant, mobile, streaming, object storage, archival, polling, push notifications, etc are commonly seen in the exam. Time management is very important when taking AWS certification exams, so be sure to monitor the time you consume for each question.
