A development subnet must access an Azure Storage account privately, but the security team does not want to create a private IP in the VNet. They only want the subnet identity to be extended to the storage service. Which feature should the administrator configure?

Answer choices

Why each option matters

Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.

A

Distractor review

Private endpoint

A private endpoint assigns a private IP in the VNet, which is explicitly not what the security team wants here.

B

Best answer

Service endpoint

A service endpoint extends the VNet and subnet identity to the supported Azure service without creating a private IP address in the VNet. That fits the requirement exactly because the team wants private access semantics from the subnet while avoiding a private endpoint. It is the correct choice when the main goal is to restrict service access to a subnet rather than provide a private IP-based connection.

C

Distractor review

Azure Front Door

Azure Front Door is an edge delivery service for web traffic and does not provide subnet-level private access to storage.

D

Distractor review

Network security group outbound rule

An NSG rule can block or allow traffic but cannot provide private service connectivity or subnet identity extension.

Common exam trap

Common exam trap: usable hosts are not the same as total addresses

Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.

Technical deep dive

How to think about this question

Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.

KKey Concepts to Remember

  • CIDR notation defines the prefix length.
  • Block size helps identify subnet boundaries.
  • Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
  • The required host count determines the smallest suitable subnet.

TExam Day Tips

  • Write the block size before choosing the subnet.
  • Check whether the question asks for hosts, subnets or a specific address range.
  • Do not confuse /24, /25, /26 and /27 host counts.

FAQ

Questions learners often ask

What does this AZ-104 question test?

CIDR notation defines the prefix length.

What is the correct answer to this question?

The correct answer is: Service endpoint — Service endpoints are the right fit when a subnet needs secure access to a supported Azure service without deploying a private IP for that service in the VNet. They extend the subnet identity to the service, allowing administrators to restrict access by subnet while keeping the traffic on the Azure backbone. If the requirement had been to place the service behind a private IP in the VNet, a private endpoint would be the better choice instead. Why others are wrong: A is the opposite of the stated requirement because it does create a private IP in the VNet. C is for traffic acceleration and web delivery, not subnet-to-storage access control. D only filters traffic and does not establish private connectivity.
