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

TrackEvent

TrackEvent sends each event individually. At millions of events per day, this can lead to high costs and potential throttling.

B

Distractor review

TrackMetric

TrackMetric does not support dimensions (like browser type) natively and is less flexible for pre-aggregation.

C

Best answer

GetMetric

GetMetric is designed for high-volume metrics with dimensions and performs client-side aggregation for efficiency.

D

Distractor review

TrackDependency

TrackDependency is used for recording calls to external dependencies, not for custom metrics like page views.

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.

An application stores customer invoices in Azure Blob Storage. Deleted blobs must be recoverable for 14 days. What should be enabled?

Question 2

You are deploying a containerized application to Azure Container Instances. The application requires a custom domain name and SSL/TLS termination. You need to configure these features. Which resource should you create alongside the container group?

Question 3

A developer needs to run a Kusto query against application request data to identify 95th percentile latency by operation. Where should the query be run? The architecture review board prefers a managed AWS-native control.

Question 4

You are developing a web app that authenticates users via Microsoft Entra ID. The app needs to read the user's profile and send emails on their behalf. You want to minimize user consent prompts. Which OAuth 2.0 grant type should you use?

Question 5

You are developing an Azure Function that processes messages from an Azure Service Bus queue. The function uses a Service Bus queue trigger and runs on a Consumption Plan. The queue receives a high volume of messages in bursts. You need to ensure that the function scales out to handle the load but does not exceed 10 concurrent instances. Which configuration should you apply?

Question 6

You are monitoring an Azure App Service using Application Insights. You notice that the server response time is high for certain requests. You need to drill down to see which external dependencies (like databases or APIs) are causing the delay. Which Application Insights feature should you use?

FAQ

Questions learners often ask

What does this AZ-204 question test?

Static NAT maps one inside address to one outside address.

What is the correct answer to this question?

The correct answer is: GetMetric — The GetMetric API is designed for high-volume scenarios by pre-aggregating data on the client side before sending it to Application Insights. This reduces network traffic and cost while maintaining accuracy. TrackEvent sends each event individually, which can cause performance and quota issues at scale. TrackMetric is older and does not support dimensions natively. TrackDependency is for tracking external calls, not page views.
