Purge Protection enforces a mandatory retention period during which no one—including admins—can permanently purge a soft-deleted vault or object.

- 1 KB
- 10 KB
- 25 KB (Correct answer)
- 64 KB
Correct answer: 25 KB
Azure Key Vault secrets are limited to 25 KB per value; use Azure Blob Storage with envelope encryption for larger payloads.
Question 5: Compared to Key Vault Access Policies, what additional granularity does Azure RBAC provide for Key Vault?
