Full question →easymulti selectObjective-mapped
A VM-hosted app needs to upload blobs without storing a storage account key or password on the VM. Which two authentication options meet this requirement? 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
System-assigned managed identity
A system-assigned managed identity lets the VM authenticate to Azure services without a stored secret.
B
Best answer
User-assigned managed identity
A user-assigned managed identity also avoids secrets on the VM and can be reused across resources.
C
Distractor review
Storage account access key in an application setting
An access key is a long-lived secret, so it violates the requirement to avoid stored credentials.
D
Distractor review
Shared access signature token saved on the VM
A SAS token is still a secret and must be stored and rotated, so it does not meet the requirement.
E
Distractor review
Anonymous public access to the container
Anonymous access removes authentication, but it is not appropriate for a secure upload scenario.
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: System-assigned managed identity — Managed identities are the best fit when a workload must access Azure resources without keeping passwords, keys, or other secrets on the machine. A system-assigned identity is tied to one VM, while a user-assigned identity can be shared and reused. Both authenticate through Microsoft Entra ID and can be granted storage permissions through RBAC. That makes them secure, operationally simple options for blob uploads. Why others are wrong: The storage account key and a SAS token are both secrets that would need to be stored or handed to the application. Anonymous access is insecure and would normally be disabled for business data. The requirement explicitly says not to store a key or password on the VM, so only managed identities satisfy it.
