Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A team needs to run a Linux container for 15 to 20 minutes at a time, triggered by an external system. They do not want to manage servers, clusters, or a web framework. Which Azure service is the best fit?
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
A virtual machine
A VM would require operating system management and is unnecessary for a short container task with no server administration requirement.
B
Best answer
Azure Container Instances
Azure Container Instances is the best fit for short-lived container execution without managing servers or a cluster. It is well suited for event-driven or scheduled jobs that run for a limited time and then exit, which matches the requirement to process work for only 15 to 20 minutes.
C
Distractor review
Azure App Service
App Service is optimized for hosting web apps and APIs, not for a simple one-off container job that exits after processing.
D
Distractor review
Azure Kubernetes Service
AKS is powerful for orchestrated container platforms, but it adds cluster management that the team explicitly wants to avoid.
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: Azure Container Instances — Azure Container Instances is the correct choice because the workload is a short-lived container job that should run without cluster or server management. ACI lets administrators run a container on demand, pay only for the resources used, and avoid the overhead of maintaining a VM or Kubernetes platform. That makes it an excellent fit for triggered processing tasks that start, complete, and exit within minutes rather than serving continuous web traffic. Why others are wrong: App Service is more appropriate for web applications and APIs that stay online, not for a transient container job. AKS introduces orchestration and cluster administration that the scenario explicitly rejects. A VM would add patching, monitoring, and operating system management for no operational benefit in this use case.
