Which of these are benefits provided by AWS Trusted Advisor? (Choose two.)

AWS Trusted Advisor is a service that inspects your AWS environment and provides recommendations in five categories: cost optimization, performance, security, fault tolerance, and service limits. Therefore, "Recommendations to optimize costs" and "Security-related checks" are correct benefits. Trusted Advisor does not provide access to Amazon SQS; SQS is a messaging service. While Trusted Advisor does perform service limit checks, they are not refreshed every hour; the refresh frequency varies by check but is not hourly for all of them. Trusted Advisor also does not manage IAM approvals; IAM is for managing access to AWS resources.
