Quick Answer

The answer is that the VM creation will be denied because the Azure Policy explicitly uses the "deny" effect to block the creation of any network interface that includes a public IP address. This policy evaluates the resource before deployment, and if the condition—a network interface with a public IP—is met, Azure Resource Manager rejects the entire create operation, preventing the VM from being provisioned. On the Microsoft Cybersecurity Architect exam, this scenario tests your understanding of Azure Policy effects, particularly the difference between "deny" and "audit"; a common trap is assuming the policy only audits or creates a separate public IP, but the deny effect stops the resource creation at the source. Remember that "deny" is a hard block, not a warning, so when you see a policy targeting network interfaces with public IPs, think of it as a gate that slams shut before any resource is built. A useful memory tip: "Deny deletes the request, audit only alerts the rest."

SC-100 Design security solutions for infrastructure Practice Question

This SC-100 practice question tests your understanding of design security solutions for infrastructure. 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.

Exhibit

{
  "properties": {
    "displayName": "Deny public IP on NICs",
    "policyType": "Custom",
    "mode": "All",
    "policyRule": {
      "if": {
        "allOf": [
          {
            "field": "type",
            "equals": "Microsoft.Network/networkInterfaces"
          },
          {
            "field": "Microsoft.Network/networkInterfaces/ipConfigurations[*].publicIPAddress.id",
            "exists": "true"
          }
        ]
      },
      "then": {
        "effect": "Deny"
      }
    }
  }
}

Refer to the exhibit. A company applies this Azure Policy to their subscription. An administrator tries to create a VM with a public IP address. What will happen?

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 VM creation will be denied

Option A is correct because the policy denies creation of network interfaces with a public IP. Option B is wrong because the policy does not audit, it denies. Option C is wrong because the policy applies to all resources. Option D is wrong because the policy does not create a public IP.

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 public IP will be automatically removed

    Why it's wrong here

    The policy denies creation, it does not modify.

  • ✓

    The VM creation will be denied

    Why this is correct

    The policy denies creation of NICs with public IP.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    The VM will be created, but an alert will be generated

    Why it's wrong here

    The effect is Deny, not Audit.

  • ✗

    The policy will only apply to VMs in a specific resource group

    Why it's wrong here

    The policy is assigned to the subscription, not a resource group.

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

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.
