Question 73 of 997

Implement Azure security →mediumMultiple ChoiceObjective-mapped

Quick Answer

The correct configuration is to configure a service endpoint for Microsoft.Storage on the subnet, add a firewall rule to allow that subnet, and then enable 'Allow trusted Microsoft services'. This works because the service endpoint ensures traffic from the specific subnet to the storage account stays on the Azure backbone, while the firewall rule explicitly restricts data-plane access to only that subnet. Enabling 'Allow trusted Microsoft services' is the key to permitting Azure portal management—since the portal uses control-plane operations (like listing containers) that are performed by trusted Microsoft services, this setting bypasses the network restrictions for those actions. On the AZ-204 exam, this scenario tests your understanding of how to balance security with manageability; a common trap is forgetting that the portal itself is not a client in your subnet, so without the trusted services exception, you would lose the ability to browse storage from the portal. Remember the mnemonic: "SE-FW-TS" (Service Endpoint, Firewall rule, Trusted Services) to lock down data but keep control open.

AZ-204 Implement Azure security Practice Question

This AZ-204 practice question tests your understanding of implement azure security. 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 restrict access to an Azure Storage account so that only a specific subnet of a virtual network can access the data. Additionally, you need to allow management access from the Azure portal (e.g., to view containers). Which configuration should you apply?

Question 1mediummultiple choice

Review the full subnetting walkthrough →

A
Configure IP firewall rules to allow the subnet IP range and add the Azure portal's public IP addresses.
Why wrong: This is possible but less secure and harder to maintain as portal IPs can change. Also, it does not use network security boundary of the virtual network.
B
Configure a service endpoint for Microsoft.Storage on the subnet and add a firewall rule to allow the subnet, then enable 'Allow trusted Microsoft services'.
Service endpoint provides secure connectivity from the subnet. The trusted Microsoft services exception allows portal management while keeping the firewall restricted.
C
Configure a private endpoint for the storage account and disable public network access.
Why wrong: Private endpoint would also work but is more complex to set up and is not required if only subnet access and portal management are needed.
D
Configure IP ACLs to allow the subnet and also allow all Azure services.
Why wrong: Allowing all Azure services is overly permissive and does not leverage the virtual network boundary.

Correct answer & explanation

✓

Configure a service endpoint for Microsoft.Storage on the subnet and add a firewall rule to allow the subnet, then enable 'Allow trusted Microsoft services'.

Option B is correct because configuring a service endpoint for Microsoft.Storage on the subnet ensures traffic from that subnet to the storage account stays within the Azure backbone, and the firewall rule restricts access to that subnet. Enabling 'Allow trusted Microsoft services' permits Azure portal management operations (e.g., listing containers) because the portal is a trusted service that bypasses the network rules for control-plane actions.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse 'Allow trusted Microsoft services' with 'Allow all Azure services' or assume that IP-based rules for the Azure portal are static, when in fact the portal uses dynamic IP ranges that are not suitable for firewall rules.

Detailed technical explanation

How to think about this question

Service endpoints use the source IP of the virtual network's subnet as the source of the traffic, which is then matched by the storage account firewall rule. The 'Allow trusted Microsoft services' exception works by allowing traffic from Azure services that are part of the trusted platform, such as Azure Portal, Azure Monitor, and Azure Backup, to bypass the network ACLs for management-plane operations (e.g., listing containers) but not for data-plane operations unless the client also meets the network rule. This is distinct from a private endpoint, which uses a private IP from the VNet and requires DNS resolution changes, and does not inherently allow portal management without additional configuration.

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.
