The answer is to configure storage firewall rules to deny all public IPs, add the VNet as a service endpoint, and enable 'Secure transfer required' (HTTPS). This combination works because the firewall rules explicitly block any traffic not originating from the trusted VNet, while the service endpoint ensures traffic from that VNet reaches the storage account over the Azure backbone. Enabling 'Secure transfer required' enforces HTTPS for all data in transit, meeting the encryption requirement. On the AZ-500 exam, this scenario tests your understanding of network segmentation and encryption controls for Azure Storage, often appearing as a multi-step configuration where candidates must remember that a service endpoint alone does not block public access—you must also deny all public IPs in the firewall. A common trap is thinking a private endpoint or NSG alone suffices, but the private endpoint still requires a firewall rule to block public endpoints, and NSGs only filter traffic within the VNet. Memory tip: think "Firewall first, then endpoint, then HTTPS"—three distinct layers to lock down storage completely.
AZ-500 Secure compute, storage, and databases Practice Question
This AZ-500 practice question tests your understanding of secure compute, storage, and databases. 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.
You need to ensure that an Azure Storage account is accessible only from a specific virtual network (VNet) and only over HTTPS. You also want to deny access from any public IP. What should you configure?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure storage firewall rules to deny all public IPs, add the VNet as a service endpoint, and enable 'Secure transfer required' (HTTPS).
Option D is correct because you can configure firewall rules to deny all public IPs, add the VNet as a service endpoint, and enable the 'Secure transfer required' property. Option A is wrong because NSG on the subnet is not sufficient to block public internet access to the storage account. Option B is wrong because private endpoint creates a private IP, but you also need to block public access. Option C is wrong because SAS token does not restrict network location.
Key principle: Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Generate a SAS token and require HTTPS.
Why it's wrong here
SAS token does not restrict access based on network location.
✓
Configure storage firewall rules to deny all public IPs, add the VNet as a service endpoint, and enable 'Secure transfer required' (HTTPS).
Why this is correct
Firewall blocks public access, service endpoint allows VNet, and 'Secure transfer required' enforces HTTPS.
Configure a Network Security Group (NSG) on the subnet to deny all inbound traffic.
Why it's wrong here
NSG controls traffic to VMs, not to the storage account directly.
✗
Configure a private endpoint for the storage account and disable public network access.
Why it's wrong here
Private endpoint provides private connectivity, but you must also enable 'Secure transfer required' for HTTPS.
Common exam traps
Common exam trap: usable hosts are not the same as total addresses
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Detailed technical explanation
How to think about this question
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
KKey Concepts to Remember
CIDR notation defines the prefix length.
Block size helps identify subnet boundaries.
Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
The required host count determines the smallest suitable subnet.
TExam Day Tips
→Write the block size before choosing the subnet.
→Check whether the question asks for hosts, subnets or a specific address range.
→Do not confuse /24, /25, /26 and /27 host counts.
Key takeaway
Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
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.

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. You need to restrict access to an Azure Storage account so that only traffic from a specific virtual network (VNet) subnet is allowed. Which Azure Storage firewall setting should you configure?
easy
A.Create a private endpoint for the storage account.
B.Enable service endpoints on the subnet and add an IP rule.
C.Add a firewall rule with the subnet's public IP address range.
✓ D.Add a virtual network rule that references the VNet and subnet.
Why D: Option B is correct because Storage firewall rules can restrict access to specific VNets and subnets by adding a 'Virtual Network' rule. Option A is wrong because IP rules allow specific public IPs, not VNets. Option C is wrong because Private Endpoint is a separate feature that uses private IPs but requires Private Link. Option D is wrong because service endpoints are a prerequisite but the rule type is 'Virtual Network'.
Variation 2. You need to restrict access to an Azure Storage account so that only requests from a specific Azure Virtual Network are allowed. What should you configure?
easy
A.Assign an RBAC role to the VNet's managed identity
B.Configure a service endpoint for the storage account
✓ C.Configure the storage account firewall to allow access only from the VNet
D.Configure an Azure Private Endpoint for the storage account
Why C: Azure Storage firewalls and virtual network rules allow you to restrict access to specific VNets. Option B is correct. Option A is wrong because private endpoints provide private connectivity but do not automatically block other traffic. Option C is wrong because service endpoints are used for other services. Option D is wrong because RBAC controls who can access, not where from.
