Question 46 of 1,000
Secure Azure using Microsoft Defender for Cloud and Microsoft Sentinel →hardMultiple ChoiceObjective-mapped

Quick Answer

The answer is that the VMs are non-compliant because they lack the Azure Disk Encryption extension. The Azure Policy definition specifically audits for the presence of encryption settings on the VM’s disks; when those settings are absent, the policy then checks for the AzureDiskEncryption extension as the required remediation. If the extension is not installed, the condition evaluates as non-compliant, regardless of whether the underlying disks are encrypted at the host or by other means. On the AZ-500 exam, this question tests your ability to read a policy’s logical conditions rather than assuming compliance based on general security features—a common trap is confusing encryption at host with Azure Disk Encryption. Remember that this policy is narrowly scoped: it does not care about patch status, host-level encryption, or backups; it only audits for the extension. Memory tip: “No extension, no compliance—the policy checks for the tool, not the result.”

This AZ-500 practice question tests your understanding of secure azure using microsoft defender for cloud and microsoft sentinel. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.

You are reviewing the Azure Policy definition shown in the exhibit. This policy is assigned to a subscription. Several VMs are non-compliant. What is the most likely reason for the non-compliance?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

  • Clue: "most likely"

    Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.

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

✓

The VMs do not have the Azure Disk Encryption extension installed.

Option C is correct because the policy audits if Azure Disk Encryption is not enabled on VMs without encryption settings. The condition checks if encryptionSettings does not exist, and then expects the AzureDiskEncryption extension. If the extension is missing, the VM is non-compliant. Option A is wrong because the policy does not check for Windows patch status. Option B is wrong because the policy does not check for encryption at host. Option D is wrong because the policy is about disk encryption, not backup.

Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    The VMs are not backed up to Azure Backup.

    Why it's wrong here

    Incorrect. The policy is about disk encryption, not backup.

  • ✓

    The VMs do not have the Azure Disk Encryption extension installed.

    Why this is correct

    Correct. The policy audits for the presence of the AzureDiskEncryption extension on VMs without encryption settings.

    Clue confirmation

    The clue word "most likely" in the question point toward this answer.

    Related concept

    Static NAT maps one inside address to one outside address.

  • ✗

    The VMs have encryption at host enabled but not Azure Disk Encryption.

    Why it's wrong here

    Incorrect. The policy specifically requires the AzureDiskEncryption extension.

  • ✗

    The VMs are missing critical Windows security patches.

    Why it's wrong here

    Incorrect. The policy is about disk encryption, not patch management.

Common exam traps

Common exam trap: NAT rules depend on direction and matching traffic

NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.

Detailed technical explanation

How to think about this question

NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.

KKey Concepts to Remember

  • Static NAT maps one inside address to one outside address.
  • PAT allows many inside hosts to share one public address using ports.
  • Inside local and inside global describe the private and translated addresses.
  • NAT ACLs identify traffic for translation, not always security filtering.

TExam Day Tips

  • Identify inside and outside interfaces first.
  • Check whether the scenario needs static NAT, dynamic NAT or PAT.
  • Do not confuse NAT matching ACLs with normal packet-filtering intent.

Key takeaway

NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Real-world example

How this comes up in practice

An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.

What to study next

Got this wrong? Here's your next step.

Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related AZ-500 NAT questions on configuration and troubleshooting.
