AWS Certified Cloud Practitioner — Question 286

A company plans to run its IT infrastructure in the AWS Cloud. The infrastructure must be highly available. The company also must minimize the network latency between servers.

Which deployment scenario will meet these requirements?

Answer options

• A. Deploy in multiple Availability Zones in multiple AWS Regions.
• B. Deploy in one Availability Zone in one AWS Region
• C. Deploy in multiple AWS Regions. Deploy in one Availability Zone in each Region.
• D. Deploy in multiple Availability Zones in one AWS Region.

Correct answer: D

Explanation

Deploying across multiple Availability Zones within a single AWS Region ensures high availability by protecting against localized failures while maintaining low-latency connections between servers. Deploying across multiple AWS Regions introduces significant geographic distance and latency, whereas using only a single Availability Zone fails to provide high availability.
