AWS Certified SysOps Administrator – Associate (legacy) — Question 568

A SysOps Administrator is in the process of setting up a new AWS Storage Gateway. The Storage Gateway activation is failing when the Administrator attempts to activate the Storage Gateway from the Storage Gateway console.
What are the potential causes of this error? (Choose two.)

Answer options

• A. The Storage Gateway does not have an upload buffer configured.
• B. The Storage Gateway does not have a backing Amazon S3 bucket configured.
• C. The Storage Gateway does not have a cache volume configured.
• D. The Storage Gateway does not have the correct time.
• E. The Storage Gateway is not accessible from the Administrator's client over port 80.

Correct answer: A, D

Explanation

Storage Gateway activation will fail if the gateway VM's time is not synchronized, as a significant time drift prevents successful communication and handshake with AWS endpoints. Additionally, the gateway requires an allocated upload buffer to be properly configured to complete its initialization and activation workflow. Other resources, like S3 buckets and cache volumes, are typically configured after the activation phase is successful.
