- A
A service endpoint on the subnet and a storage firewall rule
Why wrong: Service endpoints do not give the storage account a private IP address in the VNet.
- B
A private endpoint and a private DNS zone linked to the VNet
A private endpoint places a private IP address for the storage service in the VNet, and the private DNS zone ensures the service name resolves to that private IP. Together, they provide private access while allowing public network access to be disabled.
- C
A public IP address and IP-based firewall exceptions
Why wrong: This keeps the service publicly reachable and does not meet the private-only requirement.
- D
A shared access signature and blob container ACLs
Why wrong: SAS and ACLs control authorization, not private network path or DNS resolution.
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 storage account must be reachable only from one Azure virtual network. The team wants the storage service to have a private IP in that VNet, public network access disabled, and name resolution to work without using the public endpoint. 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 private endpoint and a private DNS zone linked to the VNet
A private endpoint assigns the storage account a private IP from the VNet's address space, making it reachable only within that VNet. Disabling public network access ensures no traffic can reach the storage account via its public endpoint. A private DNS zone linked to the VNet enables name resolution to resolve the storage account's FQDN to the private IP without using the public endpoint.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A service endpoint on the subnet and a storage firewall rule
Why it's wrong here
Service endpoints do not give the storage account a private IP address in the VNet.
- ✓

Why this is correct
A private endpoint places a private IP address for the storage service in the VNet, and the private DNS zone ensures the service name resolves to that private IP. Together, they provide private access while allowing public network access to be disabled.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse service endpoints with private endpoints, assuming a service endpoint provides a private IP and disables public access, when in fact it only routes traffic over the Microsoft backbone while still using the public endpoint.
Detailed technical explanation
How to think about this question
A private endpoint uses a network interface (NIC) in the VNet with a private IP from the subnet, leveraging Azure Private Link to tunnel traffic to the PaaS service over the Microsoft backbone. The private DNS zone (e.g., privatelink.blob.core.windows.net) must be linked to the VNet and configured with an A record for the private IP; without it, clients would still resolve the public IP via public DNS, breaking the isolation. In a real-world scenario, if the private DNS zone is not linked to the VNet, name resolution fails, and clients must use the private IP directly or configure custom DNS servers.
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.
