AWS Certified Advanced Networking – Specialty (ANS-C00) — Question 157

Which two statements about placement groups are correct? (Choose two.)

Answer options

• A. A placement group can span multiple VPCs.
• B. A placement group can span multiple Availability Zones.
• C. You cannot merge placement groups.
• D. It is best to use the same instance types in a placement group.

Correct answer: A, C

Explanation

Option A is correct because placement groups are designed to operate within a single VPC, but can cover multiple VPCs in specific configurations. Option C is correct since placement groups cannot be merged after their creation. Options B and D are incorrect; placement groups cannot span multiple Availability Zones and while using the same instance types is recommended, it is not a requirement.
