Your team is developing an application in Google Cloud that executes with user identities maintained by Cloud Identity. Each of your application’s users will have an associated Pub/Sub topic to which messages are published, and a Pub/Sub subscription where the same user will retrieve published messages. You need to ensure that only authorized users can publish and subscribe to their own specific Pub/Sub topic and subscription. What should you do?

  1. Bind the user identity to the pubsub.publisher and pubsub.subscriber roles at the resource level.
  2. Grant the user identity the pubsub.publisher and pubsub.subscriber roles at the project level.
  3. Grant the user identity a custom role that contains the pubsub.topics.create and pubsub.subscriptions.create permissions.
  4. Configure the application to run as a service account that has the pubsub.publisher and pubsub.subscriber roles.

You are developing an ecommerce web application that uses App Engine standard environment and Memorystore for Redis. When a user logs into the app, the application caches the user’s information (e.g., session, name, address, preferences), which is stored for quick retrieval during checkout.

While testing your application in a browser, you get a 502 Bad Gateway error. You have determined that the application is not connecting to Memorystore. What is the reason for this error?

  1. Your Memorystore for Redis instance was deployed without a public IP address.
  2. You configured your Serverless VPC Access connector in a different region than your App Engine instance.
  3. The firewall rule allowing a connection between App Engine and Memorystore was removed during an infrastructure update by the DevOps team.
  4. You configured your application to use a Serverless VPC Access connector on a different subnet in a different availability zone than your App Engine instance.

Answer(s): A
