Implement Azure security →mediumMultiple ChoiceObjective-mapped

Quick Answer

The correct answer is that the storage account firewall is configured to deny all traffic except from the 192.168.1.0/24 IP range, which blocks the developer’s machine at 10.0.0.5. This is because Azure Storage Firewall IP restrictions use network ACLs with a default-deny rule, meaning only explicitly allowed IP ranges can connect; since 10.0.0.5 falls outside the permitted 192.168.1.0/24 subnet, the connection is dropped regardless of RBAC permissions. On the Microsoft Azure Developer Associate AZ-204 exam, this scenario tests your understanding of how storage firewall IP blocks override role-based access—a common trap is assuming RBAC alone grants network access, but firewalls operate at the network layer first. Remember, RBAC controls who can manage the account, while IP restrictions control who can reach it. Memory tip: think of the firewall as a bouncer checking IDs (IPs) before RBAC even gets to see the guest list.

AZ-204 Implement Azure security Practice Question

This AZ-204 practice question tests your understanding of implement azure security. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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

Refer to the exhibit.

        }
      ],
      "virtualNetworkRules": []
    }
  }
}

Refer to the exhibit. You deploy an Azure Storage account using the ARM template snippet. A developer reports that they cannot connect to the storage account from their machine with IP 10.0.0.5, even though they have the proper RBAC role. 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 storage account firewall is configured to deny all traffic except from the 192.168.1.0/24 IP range.

Option A is correct because the network ACLs have a default deny and only allow traffic from 192.168.1.0/24. The IP 10.0.0.5 is not in that range. Option B is wrong because TLS 1.2 is a requirement, but the error is network access. Option C is wrong because RBAC is correctly configured. Option D is wrong because Azure Services bypass is for Azure services, not the developer's machine.

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.

  • ✗

    The storage account is configured to bypass Azure Services, which blocks non-Azure clients.

    Why it's wrong here

    AzureServices bypass allows trusted Azure services, not all traffic.

  • ✗

    The developer does not have the Storage Blob Data Contributor role.

    Why it's wrong here

    RBAC is separate from network access.

  • ✓

    The storage account firewall is configured to deny all traffic except from the 192.168.1.0/24 IP range.

    Why this is correct

    The developer's IP is not allowed.

    Clue confirmation

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

    Related concept

    Standard ACLs match source addresses.

  • ✗

    The minimum TLS version is set to TLS 1.2, but the developer's client uses TLS 1.0.

    Why it's wrong here

    This would cause a different error, but the network ACL is the primary issue.

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.
