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. A key principle to apply: private DNS zones resolve FQDNs to private IP addresses within Azure VNets.. 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.
You create a private endpoint for an Azure Storage account. Virtual machines in VNet-Prod must resolve the storage account name to the private IP address of that endpoint. Which Azure feature should you configure?
A private DNS zone linked to VNet-Prod
A private DNS zone provides the required name resolution for the private endpoint.
A user-defined route
Why wrong: A route affects packet forwarding, not DNS resolution.
An Azure Firewall policy
Why wrong: Firewall policy governs filtering and does not provide service name mapping.
A Recovery Services vault
Why wrong: A Recovery Services vault is unrelated to private endpoint DNS resolution.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
A private DNS zone linked to VNet-Prod
A private endpoint uses a private IP address from the VNet, but DNS resolution must be explicitly configured to map the storage account's FQDN to that private IP. By creating a private DNS zone (privatelink.blob.core.windows.net) linked to VNet-Prod, Azure automatically creates an A record for the private endpoint IP, enabling VMs to resolve the storage account name to the private IP instead of the public IP.
Key principle: Private DNS zones resolve FQDNs to private IP addresses within Azure VNets.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
A private DNS zone linked to VNet-Prod
A user-defined route
Why it's wrong here
A route affects packet forwarding, not DNS resolution.
An Azure Firewall policy
Why it's wrong here
Firewall policy governs filtering and does not provide service name mapping.
A Recovery Services vault
Why it's wrong here
A Recovery Services vault is unrelated to private endpoint DNS resolution.
Common exam traps
The trap here is that candidates confuse network-level traffic control (UDRs or firewalls) with DNS resolution, assuming that routing or filtering traffic is sufficient to force private connectivity, when in fact DNS must be explicitly configured to resolve to the private IP.
Detailed technical explanation
When a private endpoint is created, Azure automatically generates a private DNS zone for the resource type (e.g., privatelink.blob.core.windows.net) and populates it with an A record pointing to the private IP. If the zone is not linked to the VNet, VMs will continue to resolve the public endpoint via Azure's default DNS (168.63.129.16), bypassing the private IP. Linking the zone enables conditional forwarding: queries for the storage account FQDN are resolved within the VNet's DNS suffix, returning the private IP.
Key takeaway
Private DNS zones resolve FQDNs to private IP addresses within Azure VNets.
Real-world example
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.
