Google PCA Practice Question: Analyze and optimize technical and business processes
Drag and drop the steps to implement a disaster recovery plan using Cloud Storage and Cloud Functions in the correct order.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable versioning on the primary bucket, then create a Cloud Function to copy new objects to the DR bucket, then test the procedure.
Versioning protects against accidental deletion. The Cloud Function copies objects to the DR bucket.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Enable versioning on the primary bucket, then create a Cloud Function to copy new objects to the DR bucket, then test the procedure.
Why this is correct
This is the correct order because versioning must be enabled first to preserve object history, then the Cloud Function is created to automatically copy new objects to the DR bucket, and finally testing validates the setup.
- ✗
Create a Cloud Function to copy new objects to the DR bucket, then enable versioning on the primary bucket, then test.
Why it's wrong here
This is incorrect because if the Cloud Function is created before enabling versioning, it may copy objects that are later accidentally deleted, and versioning would not protect the original versions. Versioning should be set up first.
- ✗
Create a Cloud Function, then test, then enable versioning.
Why it's wrong here
This is incorrect because testing before enabling versioning is meaningless; versioning is a critical component of the disaster recovery plan. Also, the function needs versioning to work correctly.
- ✗
Enable versioning, then test, then create the Cloud Function.
Why it's wrong here
This is incorrect because testing before creating the Cloud Function does not validate the recovery mechanism. The function must exist to copy objects, so it should be created before testing.

Key term
Cloud Functions
Cloud Functions are serverless compute services that let you run single-purpose code in response to events without managing servers.
