- A
Enable a service endpoint on the Azure VNet and keep the storage account public endpoint enabled.
Why wrong: 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
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
Use VNet peering only and leave the storage account firewall open to selected public IPs.
Why wrong: Peering connects VNets, but it does not provide private access from on-premises or eliminate the public endpoint requirement.
- D
Assign a public IP address to the storage account and restrict access with an NSG.
Why wrong: Storage accounts do not use NSGs, and a public IP would directly conflict with the requirement to disable internet access.
Quick Answer
The answer is to use a private endpoint for the storage account and connect on-premises through a site-to-site VPN or ExpressRoute. This is correct because a private endpoint assigns the storage account a private IP address from your Azure VNet, ensuring traffic never traverses the public internet, while a service endpoint only secures traffic from within Azure but still exposes the storage account to the public endpoint. On the AZ-104 exam, this question tests your understanding of network isolation versus service access—a common trap is confusing service endpoints (which only provide a private source IP from the VNet to the public endpoint) with private endpoints (which completely remove public exposure). For the on-premises requirement, remember that private endpoints rely on hybrid connectivity like VPN or ExpressRoute to extend the private IP path, whereas service endpoints cannot natively support on-premises traffic without additional configuration. A helpful memory tip: private endpoint = private IP inside the VNet, service endpoint = public endpoint with a private source.
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.
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
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Use a private endpoint for the storage account and connect on-premises through a site-to-site VPN or ExpressRoute path.
Option B is correct because a private endpoint assigns the storage account a private IP address from the Azure VNet, making it accessible over a private IP path. On-premises connectivity is achieved via a site-to-site VPN or ExpressRoute, which extends the private network. This configuration disables internet access by blocking the public endpoint, meeting the requirement to disable internet access.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why this is correct

Why it's wrong here

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse service endpoints with private endpoints, thinking service endpoints also provide private-only access, but service endpoints still use the public endpoint and do not block internet access by default.
Detailed technical explanation
How to think about this question
A private endpoint uses Azure Private Link, which creates a network interface with a private IP from the VNet, routing traffic to the storage account over the Microsoft backbone network. On-premises traffic flows through the VPN/ExpressRoute gateway, which uses BGP to propagate routes, ensuring the private endpoint's IP is reachable without traversing the internet. The storage account's firewall must be configured to deny public access, and the private endpoint is automatically authorized via a private endpoint connection request.
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.

Same concept, more angles
3 more ways this is tested on AZ-104
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A team wants an Azure VM in a subnet to reach a storage account securely without opening the account to the entire internet. Which two configuration choices can be used to achieve this? Select two.
easy- ✓ A.Private endpoint
- ✓ B.Service endpoint
- C.Enable anonymous blob access
- D.Move the account to the Archive tier
- E.Apply a delete lock to the storage account
Why A: Private endpoint (A) assigns a private IP address from the VM's subnet to the storage account, enabling secure connectivity over the Microsoft backbone network without exposing the account to the public internet. Service endpoint (B) extends the virtual network identity to the storage account via its public endpoint but restricts access to traffic originating from the specified subnet, also avoiding full internet exposure. Both options satisfy the requirement for secure, subnet-restricted access.
Variation 2. A storage account must be reachable only from resources in a single VNet. The team wants the storage service to use a private IP address inside that VNet and wants to disable public network access. Which feature should be configured?
medium- A.A service endpoint
- ✓ B.A private endpoint
- C.A network security group rule on the subnet
- D.A storage account firewall IP allow rule
Why B: A private endpoint assigns the storage account a private IP address from the VNet's address space, effectively bringing the service into the VNet. It also disables public network access by default when configured with the 'Deny public network access' setting, ensuring the storage account is reachable only from within that VNet.
Variation 3. A storage account must be reachable only from resources in a specific Azure subnet, and connections must not use the public endpoint. Which option should the administrator configure?
medium- A.A service endpoint on the subnet, because it keeps traffic on the Azure backbone.
- ✓ B.A private endpoint for the storage account in the subnet.
- C.A NAT gateway attached to the subnet.
- D.A storage firewall rule that allows all Azure services.
Why B: A private endpoint assigns the storage account a private IP address from the subnet, effectively bringing the service into the virtual network. This ensures all traffic to the storage account stays within the Microsoft Azure backbone and never traverses the public internet, meeting the requirement that connections must not use the public endpoint.
