Exhibit

Recovery notes:
- VM: vm-finance-01
- Data disk: disk-finance-logs was deleted accidentally
- Snapshot: snap-finance-logs-2024-11-15 exists in the same subscription
- Goal: restore the disk with minimal impact to the operating system disk

Based on the exhibit, what should the administrator do first to restore the missing data disk?

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 a managed disk from the snapshot, then attach it to the VM.

A snapshot is a point-in-time copy of a disk, and the normal recovery path is to create a new managed disk from that snapshot. After the disk is created, it can be attached to the VM or a recovery VM. This keeps the OS disk untouched and minimizes impact while restoring the missing data volume.

B

Distractor review

Recreate the VM from the marketplace image and restore applications manually.

Rebuilding the whole VM is far more disruptive than restoring only the deleted data disk.

C

Distractor review

Convert the snapshot directly into an operating system disk and replace the VM.

The snapshot represents the deleted data disk, not the OS disk, so replacing the VM is unnecessary.

D

Distractor review

Increase the VM size so that Azure automatically recreates the missing disk.

Changing VM size does not restore deleted managed disks or recover snapshot data.

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 a managed disk from the snapshot, then attach it to the VM. — A managed disk must be created from the snapshot before it can be attached or used for recovery. That is the standard Azure workflow for restoring a deleted data disk with minimal impact to the operating system disk. The snapshot is not directly mountable as a live disk in the same way a managed disk is. Creating the disk first preserves the OS volume and gives the administrator a clean recovery path. Why others are wrong: Recreating the VM is unnecessary when only one data disk is missing. Replacing the OS disk is the wrong target because the snapshot is of the deleted data disk. Increasing VM size has no relationship to disk recovery or snapshot restoration.
