Question 902 of 1,000
Secure Azure using Microsoft Defender for Cloud and Microsoft Sentinel →hardMultiple ChoiceObjective-mapped

Quick Answer

The answer is that the policy mode 'Indexed' requires a remediation task to be created, so the policy only evaluates resources when a remediation task is triggered. This is because an Indexed policy mode only evaluates resource types that support tags and location, meaning it does not automatically scan for compliance on every resource in the scope; instead, it waits for a manual or scheduled remediation task to initiate the evaluation. On the AZ-500 exam, this scenario tests your understanding of how DeployIfNotExists policies interact with policy modes—a common trap is assuming that assigning the policy is enough to start compliance evaluation, when in fact the 'Indexed' mode requires explicit remediation to trigger the deployment. Remember that for a DeployIfNotExists policy to evaluate and deploy, you must create a remediation task; otherwise, the compliance state will remain 'Not started'. A useful memory tip is "Indexed needs a nudge"—if the mode is Indexed, you must manually kick off remediation to see results.

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. 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.

          },
          "deployment": {

                  "value": "[parameters('workspaceId')]"
                }
              }
            }
          }
        }
      }
    },
    "parameters": {
      "workspaceId": {
        "type": "String",
        "metadata": {
          "displayName": "Log Analytics workspace ID"
        }
      }
    }
  }
}

Refer to the exhibit. You assign this built-in policy to a resource group containing Linux VMs. The policy is intended to deploy the Log Analytics agent if it is missing. After the assignment, you notice that the policy does not evaluate any VMs and the compliance state is 'Not started'. What is the most likely reason?

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 policy mode 'Indexed' requires a remediation task to be created; the policy only evaluates resources when a remediation task is triggered.

Option C is correct because the policy mode is 'Indexed', which only evaluates resource types that support tags and location; virtual machines are indexed, but the policy might not trigger if the assignment scope is not a management group or subscription. Option A is wrong because the parameter is required. Option B is wrong because the agent is not installed, but the policy should evaluate. Option D is wrong because built-in policies can be assigned.

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.

  • ✗

    The policy parameter 'workspaceId' is not provided during assignment.

    Why it's wrong here

    If the parameter is missing, the assignment would fail, not show 'Not started'.

  • ✗

    Built-in policies cannot be assigned directly to a resource group; they must be assigned to a management group.

    Why it's wrong here

    Built-in policies can be assigned to any scope.

  • ✓

    The policy mode 'Indexed' requires a remediation task to be created; the policy only evaluates resources when a remediation task is triggered.

    Why this is correct

    'DeployIfNotExists' policies with 'Indexed' mode require a remediation task to evaluate and deploy.

    Clue confirmation

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

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    The Log Analytics agent is already installed on all VMs.

    Why it's wrong here

    If installed, the policy would show 'Compliant'.

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.

Trap categories for this question

  • Command / output trap

    If the parameter is missing, the assignment would fail, not show 'Not started'.

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

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.
