   You are using the Cloud Resource Manager API to list all projects in your organization. The API returns a maximum of 300 projects per page. You have 1,000 projects. Your code currently makes a single request and only processes the first page. You need to retrieve all projects. What should you do?

   • AMake multiple requests with different 'pageToken' values guessed from the response.
   • BUse the 'filter' parameter to narrow down the results to fewer than 300.
   • CIncrease the 'pageSize' parameter to 1000.
   • DLoop until the response does not contain a 'nextPageToken', using the token in each subsequent request.

   Your application calls the Cloud Pub/Sub API to publish messages. You have implemented exponential backoff with jitter. However, you are still seeing high latency and some requests are timing out. You suspect that the backoff parameters are not optimal. What should you do?

   • AIncrease the maximum retry delay to allow more time for the service to recover.
   • BAnalyze the error codes and adjust the backoff strategy based on the specific error type.
   • CDecrease the initial retry delay to retry sooner.
   • DUse a fixed delay instead of exponential backoff.
