Technical Processes — GCP PCA Practice Question 33

How to approach this question

Identify the GCP feature that provides instant, block-level backups.

Full Answer

B.Flush the database to disk, take a Persistent Disk snapshot, and immediately resume database operations.✓ Correct

Persistent Disk snapshots are the standard way to back up disks in GCP. They are incremental and asynchronous. To ensure application consistency for a database, you flush the buffers to disk (e.g., `FLUSH TABLES WITH READ LOCK` in MySQL), issue the GCP snapshot API call, and immediately unlock the database. The snapshot continues in the background without impacting disk performance.

Common mistakes

Assuming the database must remain locked until the snapshot finishes uploading, which is incorrect for PD snapshots.

You need to back up a 500 GB Persistent Disk attached to a Compute Engine instance. The disk contains a highly active database. You want to minimize the time the database is locked during the backup process. What is the most efficient way to take the backup?
