Full question →mediummultiple choiceObjective-mapped
An organization has an Azure Storage account that must be reachable from Azure VMs and from an on-premises application. Internet access to the storage account must be disabled, and the service should be accessible only over private IP paths. Which solution best meets the requirement?
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 Azure VNet and keep the storage account public endpoint enabled.
Service endpoints extend VNet identity to supported services, but they do not provide a private IP for the service and do not satisfy the on-premises private-path requirement by themselves.
B
Best answer
Use a private endpoint for the storage account and connect on-premises through a site-to-site VPN or ExpressRoute path.
A private endpoint gives the storage account a private IP in a VNet, which keeps traffic off the public internet. Because the on-premises application also needs access, the on-premises network must have private connectivity to that VNet, typically through a site-to-site VPN gateway or ExpressRoute. This design satisfies both private access and the no-public-access requirement.
C
Distractor review
Use VNet peering only and leave the storage account firewall open to selected public IPs.
Peering connects VNets, but it does not provide private access from on-premises or eliminate the public endpoint requirement.
D
Distractor review
Assign a public IP address to the storage account and restrict access with an NSG.
Storage accounts do not use NSGs, and a public IP would directly conflict with the requirement to disable internet access.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this AZ-104 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Use a private endpoint for the storage account and connect on-premises through a site-to-site VPN or ExpressRoute path. — A private endpoint places the storage service on a private IP in the Azure VNet, which prevents exposure through the public internet. However, because the workload also needs access from on-premises, the on-premises network must be able to reach that VNet through a hybrid network path such as site-to-site VPN or ExpressRoute. That combination is the correct way to keep the service private while supporting both environments. Why others are wrong: Service endpoints do not create a private IP for the service and are limited to Azure-originated traffic. VNet peering helps between VNets only; it does not connect the on-premises network. A storage account cannot be protected with NSGs, and assigning public exposure is the opposite of the stated security requirement.
