Which of the following will help a user determine if they need to request a VPC service limit increase?
AWS Personal Health Dashboard
AWS Trusted Advisor
AWS Cost and Usage Report
AWS Service Catalog
Explanations:
AWS Personal Health Dashboard provides alerts and remediation guidance for events impacting your AWS resources but does not monitor VPC service limits.
AWS Trusted Advisor monitors service limits, including VPC limits, and alerts users when they are close to exceeding them, making it useful for determining if a limit increase is necessary.
AWS Cost and Usage Report provides detailed billing and usage data but does not directly indicate VPC service limits.
AWS Service Catalog allows users to manage approved services and configurations but does not track or alert on VPC service limits.
I plan that the answer is:
AWS Trusted Advisor
