Question 358 of 997
Connect to and consume Azure services and third-party services →mediumMultiple ChoiceObjective-mapped

Quick Answer

The correct answer is that the policy denies the creation of storage accounts which do not have a virtual network rule allowing vnet1 and have the default action set to Deny. This behavior stems from how Azure Policy evaluates network ACLs: the deny effect triggers when the storage account’s network rules fail to include the required virtual network rule and the default action is not set to explicitly deny all other traffic. On the AZ-204 exam, this tests your understanding of how Azure Policy enforces network security boundaries, often appearing in scenario-based questions where you must distinguish between denying non-compliant configurations versus blocking all traffic. A common trap is confusing the deny effect with a blanket block—remember, the policy only denies accounts that lack the specified rule and default Deny, not accounts that already meet the requirement. Memory tip: “Deny the missing, not the existing”—the policy targets what is absent, not what is present.

AZ-204 Practice Question: Connect to and consume Azure services and third-party services

This AZ-204 practice question tests your understanding of connect to and consume azure services and third-party services. 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 an Azure Policy definition that applies to storage accounts. The policy has an effect of 'deny' and specifies network ACLs. What is the intended behavior of this policy?

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

✓

Deny creation of storage accounts that do not have a virtual network rule allowing vnet1 and default action set to Deny

Option A is correct. The policy denies storage accounts that do not have the specified virtual network rule and default action Deny. Option B is wrong because it allows all networks. Option C is wrong because it denies all traffic. Option D is wrong because it only allows traffic from vnet1.

Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.

Answer analysis

Option-by-option breakdown

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

  • ✗

    Allow all storage accounts to be created regardless of network rules

    Why it's wrong here

    The effect is 'deny', so it denies non-compliant accounts.

  • ✗

    Deny all traffic to storage accounts

    Why it's wrong here

    The policy only affects creation/update, not traffic.

  • ✓

    Deny creation of storage accounts that do not have a virtual network rule allowing vnet1 and default action set to Deny

    Why this is correct

    The policy denies any storage account that does not meet the network ACL conditions.

    Related concept

    Standard ACLs match source addresses.

  • ✗

    Allow only traffic from the specified virtual network

    Why it's wrong here

    The policy does not allow traffic; it denies non-compliant deployments.

Common exam traps

Common exam trap: ACLs stop at the first match

ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.

Detailed technical explanation

How to think about this question

ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.

KKey Concepts to Remember

  • Standard ACLs match source addresses.
  • Extended ACLs can match source, destination, protocol and ports.
  • The first matching ACL entry is used.
  • There is usually an implicit deny at the end.

TExam Day Tips

  • Check inbound versus outbound direction.
  • Read the ACL from top to bottom.
  • Look for a broader permit or deny above the intended line.

Key takeaway

ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.

Real-world example

How this comes up in practice

A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.

What to study next

Got this wrong? Here's your next step.

Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related AZ-204 ACL questions on filtering logic and placement.
