6 Free AWS SAA Design Resilient Architectures Practice Questions with Answers
Each question below includes 4 answer options, the correct answer, and a detailed explanation. These are real questions from the FlashGenius AWS SAA-C03 question bank for the Design Resilient Architectures domain (26% of the exam).
Sample Question 1 — Design Resilient Architectures
A company needs a highly available web application. Which combination of AWS services provides the BEST redundancy and fault tolerance?
- A. EC2 instances in a single Availability Zone with Elastic Load Balancing
- B. EC2 instances across multiple Availability Zones with Elastic Load Balancing and Auto Scaling (Correct answer)
- C. S3 for static content and EC2 instances in a single Availability Zone
- 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 2 — 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?
- A. Amazon EC2
- B. Amazon S3
- C. AWS Auto Scaling (Correct answer)
- 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 3 — Design Resilient Architectures
What is the primary benefit of using Amazon S3 for storing application data?
- A. Guaranteed low latency
- B. High availability and durability (Correct answer)
- C. High-performance computing capabilities
- D. Real-time data processing
Correct answer: B
Explanation: Amazon S3 is designed for high availability and durability, with data replicated across multiple Availability Zones. This ensures data is highly resistant to failures.
Sample Question 4 — Design Resilient Architectures
You need to design a system that can withstand a regional outage. Which strategy is MOST effective?
- A. Deploying all resources in a single Availability Zone.
- B. Using multiple Availability Zones within the same region.
- C. Deploying resources across multiple AWS Regions. (Correct answer)
- D. Using only serverless technologies.
Correct answer: C
Explanation: Deploying across multiple regions is the only option that guarantees resilience against a regional outage. Options A and B are vulnerable to regional failures.
Sample Question 5 — Design Resilient Architectures
Which AWS service helps to protect against Denial of Service (DoS) attacks?
- A. Amazon S3
- B. AWS Shield (Correct answer)
- C. Amazon CloudWatch
- D. AWS Auto Scaling
Correct answer: B
Explanation: AWS Shield is a managed DDoS protection service that helps protect applications against DDoS attacks.
Sample Question 6 — Design Resilient Architectures
Your application relies on a message queue. Which service provides the best durability and high availability for this purpose?
- A. Amazon SQS (Correct answer)
- B. Amazon SNS
- C. Amazon Kinesis
- D. Amazon DynamoDB
Correct answer: A
Explanation: Amazon SQS (Simple Queue Service) is a durable, highly available message queue service designed for reliable asynchronous communication.
