Explanation

Important note: The provided answer key appears to be incorrect. Based on how AWS actually works, C is the correct answer, not A.

In a shared VPC (via AWS Resource Access Manager), EC2 instance quotas are enforced at the account level - instances launched by a participant account in a shared subnet count against the participant account's quota, not the VPC owner's. Therefore, when the SysOps administrator in the participant account hits InstanceLimitExceeded, they must request a quota increase for the participant account through AWS Service Quotas or AWS Support.

Option A (request from the VPC owner) is wrong because the VPC owner's quotas are unaffected by instances the participant launches - quota enforcement is always per-account. Option B (different region) would technically create new capacity, but it dodges the real issue and isn't a fix - it just moves the work somewhere else. Option D (different AMI) has no effect on instance limits whatsoever; the AMI only determines the OS/software image, not quota consumption.

Memory tip: Think "who owns the instance, pays the quota." The participant account owns the EC2 instances it launches (even in a shared subnet), so the participant account's quota is what gets consumed and what needs to be raised.

If this question appeared on an official AWS practice exam, it may contain an error in the answer key, or there is a very specific scenario the question is describing that differs from standard shared VPC behavior. I'd recommend verifying against AWS documentation before trusting answer key A.
