AWS SAA Practice Questions

Master the Design Cost-Optimized Architectures Domain

Test your knowledge in the Design Cost-Optimized Architectures domain with these 5 practice questions. Each question is designed to help you prepare for the AWS SAA certification exam with detailed explanations to reinforce your learning.

Question 1

Your organization needs a cost-effective solution to distribute content globally with low latency. Which AWS service should you use?

A) Amazon CloudFront

B) Amazon S3

C) AWS Global Accelerator

D) Amazon RDS

Show Answer & Explanation

Correct Answer: A

Explanation: CORRECT: Amazon CloudFront is a content delivery network (CDN) that provides global distribution with low latency and cost-effectiveness. OPTION A: This option is correct as CloudFront is designed for global content distribution. OPTION B: S3 is for storage, not content distribution. OPTION C: Global Accelerator is for improving application availability and performance, not content delivery. OPTION D: RDS is for relational databases, not content distribution.

Question 2

What is the most cost-effective storage class for data that is infrequently accessed but requires rapid access when needed?

A) Amazon S3 Standard

B) Amazon S3 Intelligent-Tiering

C) Amazon S3 One Zone-IA

D) Amazon S3 Glacier Deep Archive

Show Answer & Explanation

Correct Answer: C

Explanation: Amazon S3 One Zone-IA is cost-effective for infrequent access data that does not require multiple Availability Zone redundancy. S3 Standard is more expensive, Intelligent-Tiering automatically moves data but may not be as cost-effective, and Glacier Deep Archive is for archival data with slower retrieval times.

Question 3

A startup wants to build a scalable web application with unpredictable traffic patterns. Which AWS service is best suited for cost-effective automatic scaling?

A) EC2 with Auto Scaling

B) Elastic Beanstalk

C) Lambda with API Gateway

D) RDS with Read Replicas

Show Answer & Explanation

Correct Answer: C

Explanation: CORRECT: Lambda with API Gateway is cost-effective for unpredictable traffic as it scales automatically with demand and charges only for usage. OPTION A: EC2 with Auto Scaling requires managing instances and can incur costs even when idle. OPTION B: Elastic Beanstalk simplifies deployment but may not be as cost-effective as serverless for sporadic traffic. OPTION D: RDS with Read Replicas is used for database scaling, not web application scaling.

Question 4

What is a key benefit of using AWS Savings Plans for your EC2 instances?

A) Guaranteed highest performance.

B) Eliminates all upfront costs.

C) Provides significant discounts on EC2 usage.

D) Automatically scales instances based on demand.

Show Answer & Explanation

Correct Answer: C

Explanation: AWS Savings Plans offer a significant discount on your EC2 usage in exchange for a commitment to a certain level of spend over a period of time. They do not guarantee the highest performance (A), eliminate upfront costs (B), or automatically scale your instances (D).

Question 5

Your team needs to deploy a web application across multiple regions to ensure low latency and high availability. Which AWS service can help optimize costs while distributing traffic efficiently?

A) AWS Direct Connect

B) Amazon CloudFront

C) AWS Global Accelerator

D) Elastic Load Balancing

Show Answer & Explanation

Correct Answer: B

Explanation: CORRECT: Amazon CloudFront is a content delivery network (CDN) that caches content at edge locations, reducing latency and optimizing costs by reducing the need for direct requests to the origin server. OPTION A: AWS Direct Connect is for dedicated network connections, not global traffic distribution. OPTION B: CloudFront is correct for low latency and cost optimization. OPTION C: AWS Global Accelerator improves performance but does not optimize costs like CloudFront. OPTION D: Elastic Load Balancing distributes traffic but does not cache content globally.
