Free Google Associate Cloud Engineer practice questions

Sample question 1. A Compute Engine VM needs more memory, and its data persistent disk is nearly full. The engineer is planning the maintenance steps. Which two statements are accurate? (Choose two.)

1. The machine type can be changed while the VM keeps running, with no restart.
2. The disk can later be reduced to its original size if the extra space goes unused.
3. The VM must be stopped before its machine type can be changed.
4. Growing the disk requires restoring a snapshot into a new, larger disk.
5. The disk can be enlarged while attached; the file system is then resized to use the space.

Sample question 2. To reduce the attack surface, an engineer tries to disable an API in a project, but the request fails with an error. Other APIs that are still enabled in the project rely on it. What is happening?

1. Only the project Owner can disable an API, even for users who can enable APIs.
2. APIs cannot be disabled while the project is linked to a billing account.
3. Disabling a service that enabled services depend on fails unless the dependents are disabled too.
4. APIs become permanent once used, so the only option is to shut down the project.

Sample question 3. An application on a Compute Engine VM must publish messages to a Pub/Sub topic. A developer proposes downloading a JSON key for a service account and copying it onto the VM. What is the BEST alternative?

1. Attach the service account to the VM and grant it Pub/Sub Publisher on the topic.
2. Store the JSON key in an environment variable instead of in a file on the disk.
3. Run gcloud auth login on the VM with the developer’s own Google account so the app inherits it.
4. Keep the key file on the VM but rotate it every week.
