A storage account is failing writes, and the team also wants to correlate those errors with subscription-level changes such as role assignments or deployments. What should the administrator configure?
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
Rotate the storage account keys and review access from the portal activity feed.
Key rotation can be a security practice, but it does not collect telemetry or centralize error and change data for troubleshooting.
B
Best answer
Create diagnostic settings on the storage account and the subscription that send logs to the same Log Analytics workspace.
Diagnostic settings are the correct mechanism for exporting both resource logs and subscription Activity log events to Log Analytics. Putting them in the same workspace lets the team correlate storage failures with changes such as deployments or role assignments in one KQL query.
C
Distractor review
Place the storage account behind an availability set so writes remain available during maintenance.
Availability sets apply to virtual machines, not to storage accounts, and they do not provide log correlation or diagnostics.
D
Distractor review
Enable a service endpoint from the application subnet and check whether the firewall blocks the writes.
A service endpoint changes network access behavior, but it does not centralize telemetry or help correlate errors with subscription changes.
Common exam trap
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.
Technical deep dive
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.

Question 1
A route table contains these entries: 10.0.0.0/8 with next hop Virtual appliance, and 10.1.1.0/24 with next hop Virtual network gateway. Which next hop will Azure use for traffic to 10.1.1.5?
Question 2
You are deploying a stateless web application on Azure virtual machines. The solution must automatically add and remove instances based on CPU demand and allow all instances to be managed as one logical group. Which Azure compute feature should you deploy?
Question 3
You are deploying a Windows Server VM for an internal app. The VM must support Secure Boot and vTPM later, its OS disk must survive host moves, and the team wants the lowest-cost managed disk tier that still behaves like a normal writable OS disk. Which two choices should you make? Select two.
Question 4

Question 5
You need to connect VNet-Hub and VNet-Spoke so that resources in both virtual networks can communicate privately over the Microsoft backbone. Both virtual networks are in the same region. What should you configure?
Question 6
You need to create a storage account that provides the lowest-cost redundant storage for non-critical data and only needs protection against local disk or server failure within a single datacenter. Which redundancy option should you choose?
FAQ
Questions learners often ask
What does this AZ-104 question test?
CIDR notation defines the prefix length.
What is the correct answer to this question?
The correct answer is: Create diagnostic settings on the storage account and the subscription that send logs to the same Log Analytics workspace. — To troubleshoot this kind of issue, the administrator needs both resource-level logs from the storage account and subscription-level Activity log events in one place. Diagnostic settings are used to stream those logs into a Log Analytics workspace, where KQL can correlate write failures with deployments, role assignments, or other changes. This gives a single operational view instead of separate portals and logs. Why others are wrong: A is wrong because key rotation does not produce the telemetry needed for correlation. C is wrong because availability sets are a compute feature, not a storage monitoring feature. D is wrong because network connectivity changes may affect access, but service endpoints do not collect logs or explain management-plane changes.
