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?
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?
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?
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?
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?
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.
