Answer: Your application needs to renew the credentials after 1 hour when they expire
Overall explanation Correct option: Your application needs to renew the credentials after 1 hour when they expire AWS Security Token Service (AWS STS) is a web service that enables you to request temporary, limited-privilege credentials for AWS Identity and Access Management (IAM) users or for users that you authenticate (federated users). By default, AWS Security Token Service (STS) is available as a global service, and all AWS STS requests go to a single endpoint at https://sts.amazonaws.com. Credentials that are created by using account credentials can range from 900 seconds (15 minutes) up to a maximum of 3,600 seconds (1 hour), with a default of 1 hour. Hence you need to renew the credentials post expiry.
