Question 979 of 1,170
Implement and Manage Virtual NetworkingmediumMultiple ChoiceObjective-mapped

Quick Answer

The answer is to configure a service endpoint on the subnet and a storage account network rule allowing that subnet. This is correct because a service endpoint extends the virtual network’s identity to the Azure Storage service, enabling the storage account’s firewall to recognize traffic from that specific subnet without assigning a private IP address or altering DNS records. On the AZ-104 exam, this scenario tests your understanding of the difference between service endpoints and private endpoints—a common trap is assuming you need a private IP for access, but the question explicitly forbids that. The key distinction is that service endpoints use the public endpoint with network-layer access control, while private endpoints assign a private IP. For a memory tip, think of a service endpoint as a “VIP pass” for your subnet—it lets the storage firewall see your subnet’s identity without changing the address, whereas a private endpoint is like giving the storage account its own private room.

AZ-104 Implement and Manage Virtual Networking Practice Question

This AZ-104 practice question tests your understanding of implement and manage virtual networking. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.

A development team runs Windows and Linux VMs in a single Azure subnet. The VMs must access an Azure Storage account, and the security team wants to restrict the storage account so only that subnet can reach it. The team does not want to create a private IP for the storage account or change DNS records. What should the administrator configure?

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

A service endpoint on the subnet and a storage account network rule allowing that subnet.

Option B is correct because a service endpoint extends the subnet's identity to the storage account, allowing the storage firewall to accept traffic from that subnet without assigning a private IP. This meets the security requirement of restricting access to only that subnet while avoiding private IPs or DNS changes.

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.

  • A private endpoint for the storage account and a private DNS zone.

    Why it's wrong here

    Private endpoints do create a private IP, which the team specifically does not want, and they usually require DNS updates for name resolution.

  • A service endpoint on the subnet and a storage account network rule allowing that subnet.

    Why this is correct

    Service endpoints extend the subnet identity to the Azure Storage service without assigning a private IP to the storage account. This allows the administrator to restrict access to the specific Azure subnet while keeping the service reachable through its normal public DNS name. It fits the requirement to avoid DNS changes and private IP creation.

    Related concept

    Read the scenario before looking for a memorised answer.

  • A site-to-site VPN between the subnet and the storage account.

    Why it's wrong here

    Storage accounts do not participate in VPN tunnels; VPN connectivity is used between networks, not directly to PaaS endpoints.

  • A user-defined route that sends storage traffic to the default internet next hop.

    Why it's wrong here

    Routes do not restrict storage access to a subnet and do not provide the access-control behavior required by the security team.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse service endpoints with private endpoints, assuming both require private IPs and DNS changes, but service endpoints operate at the network layer without altering the storage account's public endpoint.

Detailed technical explanation

How to think about this question

Service endpoints use the Azure backbone network to route traffic from the subnet to the storage account, ensuring traffic never leaves the Microsoft network. The storage account firewall evaluates the source IP of the traffic, which is the subnet's virtual network prefix, not a public IP, because the service endpoint injects the subnet's identity into the packet. This approach is ideal for scenarios where you need to secure PaaS services without the overhead of private endpoints, but it does not provide private IP connectivity or bypass the public endpoint entirely.

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.

TExam Day Tips

  • 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

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.
