   A security policy requires that API credentials be rotated every 30 days. An administrator is building a script that uses the VxRail API and wants to minimize the impact of credential rotation on the script's operation. What is the best approach?

   • AHardcode the credentials in the script and update the script when credentials are rotated.
   • BUse token-based authentication and re-authenticate to obtain a new token when the current token expires.
   • CStore the credentials in a plain text file and update the file when credentials are rotated.
   • DUse basic authentication with a service account that has a very long password expiration.

   An administrator is using the VxRail API to add a new host to an existing cluster. The POST request to /v1/hosts returns HTTP 202 Accepted with a task ID in the response body. The administrator needs to know when the host addition is complete before proceeding with the next step. What should the administrator do?

   • APoll the /v1/tasks/{taskId} endpoint periodically until the task status shows COMPLETED.
   • BRe-submit the POST request with a 'sync=true' query parameter to get a synchronous response.
   • CWait 30 seconds and then check the /v1/hosts endpoint to see if the new host appears.
   • DUse the /v1/clusters endpoint with a GET request to force the operation to complete synchronously.

   An administrator is automating a workflow that involves multiple VxRail API operations: creating a cluster, adding hosts, and configuring network settings. The administrator wants to ensure that if any operation fails, the workflow can be resumed from the point of failure without restarting from the beginning. What is the best approach?

   • ARestart the entire workflow from the beginning if any operation fails.
   • BUse a single large POST request that performs all operations at once.
   • CRun all operations in parallel and hope that most of them succeed.
   • DTrack the task ID of each asynchronous operation and use the task status to determine which steps have completed before resuming.
