A Linux VM deployed from a custom image shows only a black screen after reboot, and SSH never becomes available. The administrator needs to inspect the startup process without logging into the OS. Which two Azure features should be used? Select two.
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
Best answer
Boot diagnostics
Provides console output and screenshots for startup troubleshooting.
B
Best answer
Azure Serial Console
Lets administrators reach the VM console without SSH access.
C
Distractor review
Azure Site Recovery
Supports disaster recovery, not boot-time console inspection.
D
Distractor review
VM application health extension
Monitors app health, but it does not show boot console output.
E
Distractor review
Azure Backup restore point
Helps recover data, but it does not diagnose startup failures.
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.

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
You need to deploy several identical virtual machines and ensure that the failure of a single Azure host does not affect all of them. Which feature should you use?
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?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Boot diagnostics — Boot diagnostics and Azure Serial Console are the right tools for a VM that will not boot far enough to allow SSH or RDP. Boot diagnostics exposes screenshots and serial logs so the administrator can see where startup stopped. Serial Console provides a direct console path for troubleshooting without relying on the guest network stack. Together they give visibility into the early boot sequence. Why others are wrong: Azure Site Recovery protects against larger disaster scenarios, but it is not used to inspect a live boot failure. The VM application health extension reports workload health after the VM is running, so it cannot help when the OS never finishes booting. Azure Backup restore points are for recovery, not for startup diagnostics.
