Google PCA Practice Question: Managing Implementation and Ensuring Solution and Operations Reliability
An organization uses Cloud Storage to store critical documents. They want to protect against accidental deletion or overwriting of objects. Which feature should they enable?
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
✓
Object versioning and retention policies
Object versioning and retention policies together protect against accidental deletion and overwrites. Versioning keeps multiple versions of objects, and retention policies prevent deletion until a specified time. Uniform bucket-level access is for access control, not protection. Object lifecycle management automates transitions/deletion, not protection. Encryption protects data at rest.
