Secure Azure using Microsoft Defender for Cloud and Microsoft Sentinel →mediumMultiple ChoiceObjective-mapped

Quick Answer

The correct additional step is to grant the Log Analytics workspace access to the Key Vault key. This is required because customer-managed key encryption for Log Analytics relies on the workspace’s managed identity or service principal to authenticate and unwrap the encryption key stored in Azure Key Vault; without explicit access permissions, the workspace cannot use the CMK to encrypt all ingested data, even if infrastructure encryption is enabled. On the AZ-500 exam, this concept tests your understanding of Azure Key Vault access policies versus RBAC roles, and a common trap is confusing the workspace’s identity with Sentinel’s—Sentinel does not directly handle the key. Remember the mnemonic “Workspace wraps, Key Vault grants” to recall that the workspace must be granted access to the key, not the other way around.

AZ-500 Practice Question: Secure Azure using Microsoft Defender for Cloud and Microsoft Sentinel

This AZ-500 practice question tests your understanding of secure azure using microsoft defender for cloud and microsoft sentinel. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.

    }
  }
}

Refer to the exhibit. You are reviewing the encryption configuration of an Azure Log Analytics workspace used by Microsoft Sentinel. The configuration shows infrastructure encryption enabled and customer-managed key (CMK) from Azure Key Vault. What additional step must be taken to ensure that the CMK is used for all data?

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

✓

Grant the Log Analytics workspace access to the Key Vault key

Option C is correct because when using CMK with Log Analytics, you must grant the Log Analytics service principal (or managed identity) access to the Key Vault key. Option A is wrong because Sentinel itself does not directly use the key. Option B is wrong because the key must be in the same region as the workspace. Option D is wrong because soft-delete must be enabled, not purge protection specifically.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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 double encryption on Sentinel

    Why it's wrong here

    Incorrect: Double encryption is not a Sentinel feature.

  • ✗

    Enable purge protection on the Key Vault

    Why it's wrong here

    Incorrect: Soft-delete is required, but purge protection is optional.

  • ✓

    Grant the Log Analytics workspace access to the Key Vault key

    Why this is correct

    Correct: The workspace needs permissions to use the key.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    Ensure the Key Vault is in a different region than the workspace

    Why it's wrong here

    Incorrect: Key Vault must be in the same region.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

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.
  • Use explanations to understand the rule behind the answer.

TExam Day Tips

  • Underline the problem statement mentally.
  • 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.
