Your company has an on-premises Windows service that exposes a custom TCP endpoint. You are building an Azure Logic App that needs to send data to this endpoint. Due to network security policies, you cannot open inbound ports in the firewall. You need to establish a secure bidirectional connection without configuring a VPN. Which Azure service should you use?

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

Azure API Management with on-premises gateway

API Management is designed for HTTP APIs, not custom TCP protocols. The on-premises gateway also requires inbound connectivity.

B

Best answer

Azure Relay Hybrid Connections

Correct. Hybrid Connections allow secure, outbound-only connections from on-premises to Azure, suitable for any TCP-based protocol.

C

Distractor review

Azure Application Gateway with private link

Application Gateway handles HTTP/HTTPS traffic and requires inbound ports. Private link also requires private endpoint setup, which may not be suitable for custom TCP.

D

Distractor review

Azure ExpressRoute

ExpressRoute provides a dedicated private connection but requires significant setup and is unnecessary for the stated requirement for a single endpoint. It also doesn't solve the inbound port restriction.

Common exam trap

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Technical deep dive

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.
  • Use explanations to understand the rule behind the answer.

TExam Day Tips

  • Underline the problem statement mentally.
  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

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?

Read the scenario before looking for a memorised answer.

What is the correct answer to this question?

The correct answer is: Azure Relay Hybrid Connections — Azure Relay Hybrid Connections enable secure bidirectional communication between Azure and on-premises services using outbound connections only. The on-premises service connects to the relay, and Azure Logic Apps can then send data through the hybrid connection. This avoids opening inbound ports.
