Sample AWS SAA-C03 Practice Questions

Below are 8 free AWS SAA practice questions — 2 per domain — with the correct answer and a detailed explanation for each. These are taken directly from the FlashGenius AWS SAA question bank.

Sample Question 1 — Design Cost-Optimized Architectures

A startup is launching a new web application expecting low initial traffic. They need a cost-effective solution that can scale automatically as traffic increases. Which combination of AWS services best fits this requirement?

  1. A. Amazon EC2 with reserved instances and Elastic Load Balancing
  2. B. AWS Lambda with Amazon API Gateway and DynamoDB (Correct answer)
  3. C. Amazon EC2 instances on-demand with Auto Scaling and Elastic Load Balancing
  4. D. Amazon ECS with Fargate and an Application Load Balancer

Correct answer: B

Explanation: Lambda and API Gateway are serverless services, meaning you only pay for compute time used. This is the most cost-effective option for low initial traffic. DynamoDB is a scalable NoSQL database suitable for this scenario. Options A and C involve upfront costs (reserved instances) or higher ongoing costs (on-demand instances) than are necessary for the low initial traffic. Option D, while scalable, introduces unnecessary complexity and cost for a low-traffic application.

Sample Question 2 — Design Cost-Optimized Architectures

You need to store large amounts of infrequently accessed data cost-effectively. Which AWS service is the most appropriate choice?

  1. A. Amazon S3 Standard
  2. B. Amazon S3 Intelligent-Tiering (Correct answer)
  3. C. Amazon EBS
  4. D. Amazon RDS

Correct answer: B

Explanation: Amazon S3 Intelligent-Tiering automatically moves data between storage classes based on access patterns, optimizing storage costs. S3 Standard is more expensive for infrequently accessed data. EBS is block storage for EC2 instances and RDS is a managed database service, neither of which are suitable for archiving large datasets.

Sample Question 3 — Design High-Performing Architectures

A company needs a highly available and scalable web application. They expect significant traffic spikes during promotional periods. Which architecture best balances cost and performance?

  1. A. Single EC2 instance with Auto Scaling disabled.
  2. B. Multiple EC2 instances behind an Elastic Load Balancer (ELB) with Auto Scaling enabled. (Correct answer)
  3. C. Single EC2 instance with a large instance size.
  4. D. A single RDS instance with no redundancy.

Correct answer: B

Explanation: Option B uses an ELB for distributing traffic across multiple EC2 instances, ensuring high availability. Auto Scaling dynamically adjusts the number of instances based on demand, handling traffic spikes efficiently and cost-effectively. Options A and C lack scalability and high availability. Option D focuses only on the database and ignores the web application's needs.

Sample Question 4 — Design High-Performing Architectures

You are designing a system that needs to process large volumes of data in real-time. Which AWS service is best suited for this?

  1. A. Amazon S3
  2. B. Amazon RDS
  3. C. Amazon Kinesis (Correct answer)
  4. D. Amazon SQS

Correct answer: C

Explanation: Amazon Kinesis is a fully managed service for real-time data streaming. S3 is for object storage, RDS is for relational databases, and SQS is for message queuing, none of which are ideal for real-time processing of large data volumes.

Sample Question 5 — Design Resilient Architectures

A company needs a highly available web application. Which combination of AWS services provides the BEST redundancy and fault tolerance?

  1. A. EC2 instances in a single Availability Zone with Elastic Load Balancing
  2. B. EC2 instances across multiple Availability Zones with Elastic Load Balancing and Auto Scaling (Correct answer)
  3. C. S3 for static content and EC2 instances in a single Availability Zone
  4. D. Lambda functions deployed to a single region

Correct answer: B

Explanation: Option B offers the highest availability. Distributing EC2 instances across multiple AZs ensures redundancy. Elastic Load Balancing distributes traffic across healthy instances, and Auto Scaling adjusts the number of instances based on demand, ensuring scalability and resilience.

Sample Question 6 — Design Resilient Architectures

An application requires high availability and needs to handle sudden traffic spikes. Which service is MOST suitable for managing the application's infrastructure?

  1. A. Amazon EC2
  2. B. Amazon S3
  3. C. AWS Auto Scaling (Correct answer)
  4. D. Amazon Route 53

Correct answer: C

Explanation: AWS Auto Scaling automatically adjusts the number of EC2 instances based on demand, ensuring both scalability and high availability. While EC2 (A) is needed for the application itself, Auto Scaling (C) manages the resources and handles spikes.

Sample Question 7 — Design Secure Applications and Architectures

A company needs to store sensitive customer data at rest and in transit. Which combination of AWS services best ensures data encryption and security?

  1. A. S3 with server-side encryption using KMS and HTTPS for transit (Correct answer)
  2. B. EFS with default encryption and HTTP for transit
  3. C. S3 with client-side encryption and FTP for transit
  4. D. EBS with default encryption and SSH for transit

Correct answer: A

Explanation: Option A uses KMS-managed keys for server-side encryption in S3, providing strong encryption at rest, and HTTPS for secure data transit. Options B and C use weaker encryption methods or insecure protocols. Option D uses EBS, which is not ideal for storing large amounts of sensitive customer data.

Sample Question 8 — Design Secure Applications and Architectures

You are designing a web application that requires authentication and authorization. Which AWS service is best suited for managing user identities and access control?

  1. A. Amazon S3
  2. B. Amazon EC2
  3. C. Amazon Cognito (Correct answer)
  4. D. Amazon RDS

Correct answer: C

Explanation: Amazon Cognito is a managed service specifically designed for user authentication and authorization, providing features like user pools and identity pools. S3, EC2, and RDS are not designed for identity management.
