AWS Certified Advanced Networking – Specialty (ANS-C00) — Question 150

You have just peered two VPCs, and you need to improve performance for instances you plan on deploying. What are two steps you would take to do this?
(Choose two.)

Answer options

• A. Create two subnets in the same AZ and create a placement group.
• B. Set the MTU of your instances to 1500.
• C. Create two subnets in different AZs and create a placement group.
• D. Ensure you choose instances that use enhanced networking.

Correct answer: A, D

Explanation

Creating two subnets in the same AZ and a placement group (Option A) allows for low-latency communication and optimal network performance. Choosing instances that support enhanced networking (Option D) significantly boosts network throughput and reduces latency. Options B and C do not directly contribute to performance improvements in the same way as A and D.
