Exhibit
vm-app01 in subnet appsubnet nslookup mystorageacct.blob.core.windows.net Server: 168.63.129.16 Name: mystorageacct.blob.core.windows.net Address: 20.62.14.8 Storage account settings: Public network access: Disabled Private endpoint connections: None Business requirement: the VM must reach the blob service over a private IP address.
Based on the exhibit, which change should you make so the VM reaches the blob service over a private IP address?
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
Enable a service endpoint on the subnet and keep the current DNS configuration.
Service endpoints do not assign a private IP address to the storage service. They still use the public endpoint, so this does not satisfy the requirement shown in the exhibit.
B
Best answer
Create a private endpoint for the storage account and link the appropriate private DNS zone.
A private endpoint gives the storage service a private IP address inside the VNet, and private DNS ensures the blob name resolves to that private address. That directly matches the requirement to reach the service privately while keeping public network access disabled.
C
Distractor review
Assign the VM a public IP address and allow it through the storage firewall.
A public IP exposes the VM unnecessarily and still uses the public storage endpoint. It increases exposure and does not provide the private-IP path required in the exhibit.
D
Distractor review
Add the VM to a network security group that allows outbound TCP 443 to Azure Storage.
NSG rules can permit or deny traffic, but they do not create private connectivity. The name still resolves to a public address until a private endpoint and DNS are configured.
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: Create a private endpoint for the storage account and link the appropriate private DNS zone. — The exhibit shows that the storage account currently has no private endpoint and DNS resolution still returns a public IP address. To make the VM reach the blob service over a private IP, you must create a private endpoint and configure private DNS so the storage name resolves to that private address. Service endpoints and NSGs do not create private IP connectivity. Why others are wrong: A service endpoint keeps traffic on the public endpoint, so it does not meet the private IP requirement. Giving the VM a public IP increases exposure and is unrelated to private storage connectivity. NSGs only filter traffic; they do not change how the storage name resolves or create a private path to the service.
