Google Professional Cloud Network Engineer Question 586
Single answerGoogle Cloud PlatformYou are configuring a Google Cloud Load Balancer to serve a global web application. Users have reported intermittent connectivity issues, especially when uploading large files. After investigating, you find that the client connections are timing out before completing the uploads. To address this, you decide to customize the timeout settings. Which step is required to resolve this issue?
- A
Modify the backend service's 'timeoutSec' property to increase the timeout duration.
- B
Enable session affinity on the backend service to prevent timeouts.
- C
Increase the idle timeout for the load balancer's frontend to allow longer client connections.
- D
Configure a custom health check with a longer timeout to accommodate large uploads.
Show answer and explanation
Correct answer: A
Explanation
To resolve client connection timeout issues, you need to adjust the 'timeoutSec' property on the backend service. This setting specifies how long the load balancer waits for a backend to respond to a request. By increasing this value, you can accommodate long-running requests, such as file uploads, and prevent client connections from timing out prematurely.
- A. Correct.
Correct. The 'timeoutSec' property of the backend service determines the duration that the load balancer waits for a backend to respond. Increasing this setting helps avoid timeouts for long-running requests like large file uploads.
- B. Incorrect.
Incorrect. Session affinity ensures requests from the same client are routed to the same backend, but it does not directly address timeout issues.
- C. Incorrect.
Incorrect. The idle timeout controls the duration a connection is held open when no data is sent, but this would not solve the problem of long-running uploads timing out.
- D. Incorrect.
Incorrect. Health checks are used to determine backend availability, but they are unrelated to client connection timeout issues for uploads.
