Secure compute, storage, and databases →hardMultiple ChoiceObjective-mapped

Quick Answer

The correct answer is to add an IP rule to the ipRules array with the public IP address. This is because the ARM template sets the default action to Deny and leaves the ipRules array empty, meaning all traffic is blocked by default. To allow a specific public IP in Azure Storage firewall, you must explicitly define a rule within that array, which grants access only to that address while keeping the Deny default for all others. On the AZ-500 exam, this scenario tests your understanding of network access controls for Azure Storage, often appearing as a trap where candidates confuse IP rules with service endpoints or private endpoints—service endpoints secure traffic from a virtual network, not a public IP, and private endpoints provide private connectivity, not public access. A common mistake is changing the default action to Allow, which would open the storage account to all internet traffic. Remember the memory tip: "Deny by default, IP rule to unlock"—only a specific entry in ipRules can punch a hole for a public IP.

AZ-500 Secure compute, storage, and databases Practice Question

This AZ-500 practice question tests your understanding of secure compute, storage, and databases. 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

Refer to the exhibit.

```json
{
  "type": "Microsoft.Storage/storageAccounts",
  "apiVersion": "2023-01-01",
  "properties": {
    "minimumTlsVersion": "TLS1_2",
    "networkAcls": {

      "ipRules": [],
      "virtualNetworkRules": []
    },
    "supportsHttpsTrafficOnly": true
  }
}
```

You are deploying an Azure Storage account using the ARM template snippet shown. After deployment, you need to allow access from a specific public IP address. What should you do?

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

✓

Add an IP rule to the ipRules array with the public IP address.

The template sets default action to Deny and has no ipRules. To allow a specific IP, you must add an IP rule. Option A is correct. Service endpoints are for virtual networks, not public IPs. Private endpoints provide private connectivity. Changing default action to Allow would allow all traffic.

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.

  • ✗

    Create a private endpoint and assign it to the storage account.

    Why it's wrong here

    Private endpoint does not allow public IP access.

  • ✓

    Add an IP rule to the ipRules array with the public IP address.

    Why this is correct

    IP rules allow specific public IPs to bypass the deny default.

    Related concept

    Standard ACLs match source addresses.

  • ✗

    Configure a service endpoint for the storage account.

    Why it's wrong here

    Service endpoints are for virtual networks, not public IPs.

  • ✗

    Update the defaultAction to Allow and set ipRules to deny the IP.

    Why it's wrong here

    Changing defaultAction to Allow would allow all traffic, then ipRules can't deny.

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-500 ACL questions on filtering logic and placement.
