The correct answer is to configure the ClientTimeout setting in the Azure SignalR Service, as the default client timeout of 30 minutes is the most likely cause of disconnections after inactivity. Azure SignalR Service enforces this idle timeout to free up resources, meaning any client that remains silent for 30 minutes will be disconnected unless the server or client sends a keep-alive ping. On the AZ-204 exam, this scenario tests your understanding of SignalR’s default behavior versus common misconfigurations—many candidates mistakenly blame the App Service plan or serverless mode, but the timeout is a service-level setting. A frequent trap is assuming the default is higher or that scaling the plan resolves it, when in fact you must explicitly increase the ClientTimeout value in the SignalR service’s advanced settings. Memory tip: think “30-minute silence breaks the SignalR connection”—adjust the timeout or implement a ping interval to keep the channel alive.
AZ-204 Practice Question: Connect to and consume Azure services and third-party services
This AZ-204 practice question tests your understanding of connect to and consume azure services and third-party services. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Your Azure App Service app uses SignalR Service to push real-time updates to clients. You notice that some clients are disconnected after 30 minutes of inactivity. What is the most likely cause and solution?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The Azure SignalR Service has a default client timeout of 30 minutes; configure the ClientTimeout setting in the SignalR service
Option B is correct because Azure SignalR Service has a default client timeout of 30 minutes; it can be increased. Option A is wrong because the default is 30 minutes. Option C is wrong because serverless mode does not affect timeout. Option D is wrong because app service plan does not limit SignalR connections directly.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
The app service plan is scaled down, causing idle connections to drop
Why it's wrong here
SignalR connections are independent of app service plan scaling.
✗
The app service plan has an idle timeout of 30 minutes
Why it's wrong here
App service plan idle timeout is for the app, not SignalR connections.
✗
The SignalR service is in serverless mode, which disconnects idle clients
Why it's wrong here
Serverless mode does not have a fixed 30-minute timeout.
✓
The Azure SignalR Service has a default client timeout of 30 minutes; configure the ClientTimeout setting in the SignalR service
Why this is correct
The default client timeout is 30 minutes; increasing it resolves disconnections.

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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
