Two line-of-business VMs in a single region must stay available if one physical host is patched or fails. A zone failure is not part of the requirement. Which three actions should the administrator take? Select three.
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
Create an availability set for the application VMs before deployment.
An availability set is the correct Azure construct for protecting workloads from host-level maintenance and failures inside a datacenter. It provides the placement mechanism needed to improve availability without requiring zone-level resilience.
B
Best answer
Deploy both VMs into the same availability set.
Both VMs must be members of the same availability set for Azure to distribute them according to the set's fault and update domains. Separating them into different sets would defeat the availability design.
C
Best answer
Allow Azure to place the VMs across different fault and update domains within the availability set.
Fault and update domain distribution is the main benefit of an availability set. Azure handles the placement automatically once the VMs are in the set, reducing the chance that a single maintenance event affects all instances.
D
Distractor review
Deploy the VMs in separate availability zones to protect against a datacenter outage.
Availability zones are for protecting against datacenter or zone failures, which is beyond the stated requirement. They are not the best answer when the scenario only calls for host-level resilience.
E
Distractor review
Use a single larger VM and rely on snapshots for uptime.
A bigger single VM does not provide redundancy. Snapshots help with recovery, but they do not keep the application running during a host patch or failure event.
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: Create an availability set for the application VMs before deployment. — An availability set is the right choice when the goal is to survive host-level maintenance or failure inside one region. By placing both VMs in the same availability set, Azure spreads them across fault and update domains automatically. That reduces the chance that a single maintenance operation or hardware problem takes down both instances at the same time. Why others are wrong: Availability zones are intended for datacenter-level resilience, which the requirement explicitly does not need. A single larger VM still leaves one point of failure, and snapshots are a recovery aid rather than availability design. The correct solution is host-level redundancy through an availability set.
