- A
Add a route table that sends storage traffic to the private endpoint.
Why wrong: Routing does not change name resolution. The VMs are failing to resolve the FQDN to the private address.
- B
Link the appropriate private DNS zone to VNet-A.
Private endpoints depend on DNS so client requests resolve the service name to the private IP rather than the public endpoint. If VMs in VNet-A still receive the public address, the private DNS zone is not linked or not configured correctly for that VNet. Linking the zone ensures the Azure-provided or custom DNS path returns the private endpoint address, allowing the workloads to reach the storage account privately as intended.
- C
Create a network security group rule that allows outbound HTTPS.
Why wrong: An NSG rule may be necessary later, but it cannot change which IP address DNS returns for the storage name.
- D
Enable service endpoints for Microsoft.Storage on the subnet.
Why wrong: Service endpoints are not required for private endpoint name resolution and still do not provide the private DNS mapping needed here.
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 team deployed a private endpoint for an Azure Storage account in VNet-A. The private endpoint is healthy, but VMs in VNet-A still resolve the storage account name to the public IP address. What should the administrator configure next?
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
Link the appropriate private DNS zone to VNet-A.
When a private endpoint is deployed, the storage account's FQDN must resolve to the private IP address within the virtual network. By default, Azure Private DNS zones (privatelink.blob.core.windows.net) are not automatically linked to the virtual network. Linking the private DNS zone to VNet-A enables DNS resolution of the storage account name to the private endpoint's IP address instead of the public IP.
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.
- ✗
Add a route table that sends storage traffic to the private endpoint.
Why it's wrong here
Routing does not change name resolution. The VMs are failing to resolve the FQDN to the private address.
- ✓
Link the appropriate private DNS zone to VNet-A.
Why this is correct
Private endpoints depend on DNS so client requests resolve the service name to the private IP rather than the public endpoint. If VMs in VNet-A still receive the public address, the private DNS zone is not linked or not configured correctly for that VNet. Linking the zone ensures the Azure-provided or custom DNS path returns the private endpoint address, allowing the workloads to reach the storage account privately as intended.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse network-level controls (route tables, NSGs, service endpoints) with DNS resolution, assuming that a healthy private endpoint alone will automatically change how the storage account name is resolved.
Detailed technical explanation
How to think about this question
Azure Private Endpoint uses a network interface with a private IP from the VNet, but DNS resolution relies on the private DNS zone (privatelink.blob.core.windows.net) being linked to the VNet. Without this link, the VM's DNS resolver queries the public endpoint, returning the public IP. The private DNS zone contains an A record mapping the storage account FQDN to the private IP, and linking the zone to the VNet ensures that VMs in that VNet use this record for resolution.
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.
