Question 2

Your application requires low latency access to data. Which database service would be the MOST appropriate choice?

A) Amazon RDS (MySQL)

B) Amazon DynamoDB

C) Amazon Redshift

D) Amazon Aurora

Show Answer & Explanation

Explanation: DynamoDB is a NoSQL database optimized for high-performance, low-latency reads and writes. While Aurora is also fast, DynamoDB is generally faster for specific low-latency use cases.

Question 3

Which of the following approaches ensures high availability and resilience for a microservices architecture deployed on AWS?

A) Deploy microservices on a single EC2 instance in one Availability Zone.

B) Use Amazon ECS with services spread across multiple Availability Zones.

C) Deploy all services in a single Amazon RDS Multi-AZ instance.

D) Host all microservices in a single AWS Lambda function.

Show Answer & Explanation

Correct Answer: B

Explanation: Amazon ECS allows you to run containerized applications across multiple AZs, providing high availability and fault tolerance. Spreading services across multiple AZs ensures resilience against AZ failures.

Question 4

Which AWS service can be used to improve application availability by caching content closer to users?

A) Amazon RDS

B) Amazon CloudFront

C) Amazon S3

D) AWS Direct Connect

Show Answer & Explanation

Correct Answer: B

Explanation: CORRECT: Amazon CloudFront is a CDN that caches content at edge locations, improving application availability and performance by delivering content closer to users.

OPTION D: AWS Direct Connect provides dedicated network connectivity, not content caching.

Question 5

Your application is hosted in a single region on AWS, but you need to ensure it remains available in case of a regional failure. What strategy should you implement?

A) Use AWS Direct Connect

B) Deploy the application in multiple regions

C) Enable Multi-AZ for your RDS instances

D) Use AWS Shield Advanced

Show Answer & Explanation

Correct Answer: B

Explanation: CORRECT: Deploying the application in multiple regions ensures availability even if one region fails. OPTION A: Direct Connect is for network connections, not regional availability. OPTION B: Correct choice for regional failure protection. OPTION C: Multi-AZ is for availability within a single region. OPTION D: AWS Shield Advanced protects against DDoS attacks, not regional failures.
