- A
Soft-delete and purge protection
Correct. Soft-delete enables recovery; purge protection prevents permanent deletion during the retention period.
- B
Soft-delete and resource locks
Incorrect. Resource locks can prevent deletion of the Key Vault resource itself, but do not prevent purging of keys within the vault once soft-delete is enabled. They are not designed to protect individual keys.
- C
Purge protection and access policies
Why wrong: Incorrect. Without soft-delete, deleted keys are permanently deleted immediately and cannot be recovered, even with purge protection enabled.
- D
Soft-delete and backup
Why wrong: Incorrect. Exporting a key backup is a manual process and does not automatically protect against accidental deletion or provide the recovery capabilities of soft-delete.
Quick Answer
The correct answer is soft-delete and purge protection. Soft-delete must be enabled to retain a deleted key for a configurable retention period—defaulting to 90 days—so that the key can be recovered if accidentally removed. Purge protection must be enabled alongside it to prevent anyone, including administrators, from permanently purging the key during that retention window, ensuring the key cannot be irretrievably destroyed. On the AZ-500 exam, this pairing tests your understanding of Azure Key Vault’s data protection guarantees; a common trap is confusing resource locks with purge protection, but resource locks prevent deletion of the vault itself, not the keys inside it. Remember the mnemonic “Soft to save, Purge to protect” — soft-delete saves the key for recovery, purge protection blocks permanent deletion during the retention period.
AZ-500 Secure compute, storage, and databases Practice Question
This AZ-500 practice question tests your understanding of secure compute, storage, and databases. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company uses Azure Key Vault to store keys and secrets. They want to ensure that even if an administrator accidentally deletes a key, it can be recovered for up to 90 days. Additionally, they want to prevent anyone from permanently purging the key during that period. Which two features must be enabled?

Correct answer & explanation
Soft-delete and purge protection
Soft-delete must be enabled to retain a deleted key for a configurable retention period (default 90 days), allowing recovery. Purge protection must be enabled to prevent permanent deletion (purging) of the key during that retention period, even by administrators. Together, these two features ensure the key can be recovered and cannot be permanently deleted for up to 90 days.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse resource locks (which protect the vault resource) with purge protection (which protects the deleted key within the vault), or assume that backup alone provides the same recovery guarantee as soft-delete with purge protection.
Detailed technical explanation
How to think about this question
Soft-delete works by marking a deleted key as 'soft-deleted' and moving it to a hidden container within the vault, where it remains for a retention period (default 90 days, configurable between 7 and 90 days). Purge protection ensures that even with delete permissions, a user cannot permanently purge the key until the retention period expires; this is enforced at the vault level via the 'enablePurgeProtection' property. In a real-world scenario, if an administrator accidentally deletes a key, soft-delete allows recovery via the Azure portal or CLI, and purge protection prevents a malicious insider from bypassing the retention period.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
