Question 1easymultiple choice
Full question →easymultiple choiceObjective-mapped
Exhibit
Web app configuration: - Name: orders-web - Current authentication method: client secret stored in application settings - Requirement: Access Azure resources without storing credentials in the app - Additional requirement: When the app is deleted, the identity should be removed automatically.
Based on the exhibit, which identity should the administrator enable to remove the secret from app settings and have the identity disappear automatically when the app is deleted?
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
User-assigned managed identity
A user-assigned identity can be reused across resources, but it does not automatically disappear when one app is deleted.
B
Distractor review
Service principal with a client secret
A service principal still requires a secret or certificate to be managed, which does not remove credential storage from the app.
C
Best answer
System-assigned managed identity
A system-assigned managed identity is tied directly to the Azure resource, so it is created with the app and removed when the app is deleted. It is the best fit when you want to eliminate stored secrets and keep the identity lifecycle aligned to one resource.
D
Distractor review
Shared access signature
A SAS token is for scoped storage access, not for giving a web app a general Azure identity.
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?

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.

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 — System-assigned managed identity is the best match because the identity lifecycle follows the app itself. That means the administrator does not need to store a password or secret in configuration, and the identity is cleaned up automatically when the resource is removed. This simplifies secret management and is a common secure pattern for Azure-hosted applications that access other Azure services. Why others are wrong: A user-assigned managed identity is reusable, but it does not disappear with the app. A service principal still needs a secret or certificate to be managed separately. A SAS token is limited to storage scenarios and does not provide a general-purpose Azure resource identity.
