An application in AppSubnet must access an Azure Storage account over the public endpoint, but only traffic from that subnet should be allowed, and the traffic should stay on the Microsoft backbone. The administrator does not want to create a private IP for the service. Which two actions should be taken? Select two.

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

Best answer

Enable a service endpoint for Microsoft.Storage on AppSubnet.

A service endpoint extends the subnet identity to the storage service while still using the public endpoint path.

B

Best answer

Configure the storage account firewall to allow AppSubnet.

Storage firewall rules can restrict access to that subnet once the subnet is allowed through a service endpoint.

C

Distractor review

Create a private endpoint in AppSubnet.

A private endpoint would create a private IP, which the scenario explicitly says the administrator does not want.

D

Distractor review

Disable public network access on the storage account.

Disabling public network access would block the public endpoint instead of allowing controlled public-endpoint access.

E

Distractor review

Assign a public IP address to the storage account.

A public IP cannot be assigned to a storage account; it is a managed platform service, not a VM.

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: Enable a service endpoint for Microsoft.Storage on AppSubnet. — This scenario is the classic service-endpoint pattern. The subnet needs to be recognized by Azure Storage without introducing a private endpoint, so a Microsoft.Storage service endpoint on AppSubnet is required. Then the storage firewall must allow that subnet. Together, those settings keep traffic on the Microsoft backbone while preserving access through the public endpoint, exactly as requested. Why others are wrong: A private endpoint would create a private IP, which the requirement explicitly rejects. Disabling public network access would also block the public endpoint. A storage account cannot receive a public IP assignment like a virtual machine, so that option is not valid.
