AWS Certified Cloud Practitioner — Question 833

A company wants to minimize network latency between its Amazon EC2 instances.

Which solution achieves this goal?

Answer options

• A. Use EC2 instances in a single Availability Zone.
• B. Use EC2 instances in multiple AWS Regions.
• C. Use EC2 instances in multiple edge locations.
• D. Use EC2 instances in the same Availability Zone but in different AWS Regions.

Correct answer: A

Explanation

Deploying Amazon EC2 instances within a single Availability Zone ensures they are physically close to each other, which minimizes network latency. Distributing instances across multiple AWS Regions or edge locations increases the physical distance, thereby increasing latency. Additionally, Availability Zones are region-specific, making option D conceptually impossible as a way to reduce latency.
