Practice Test 1 | Google Cloud Certified Professional Cloud Network Engineer | Dumps | Mock Test
A company serves its application from a managed instance group behind a HTTP(S) load balancer. A new update was rolled out to the managed instance group using the Managed Instance Group Updater. User complained about having requests dropped and in-flight transactions terminated abruptly. You have been asked to remediate this issue, so it does not occur again.
What should you do?
A. Enable connection draining on the Cloud Armor and configure the connection draining timeout
B. Enable connection draining on the managed instance group and configure the connection draining timeout
C. Enable connection draining on the load balancer and configure the connection draining timeout
D. Enable connection draining on the GCP VPC and configure the connection draining timeout
Correct Answer: C
- Option A is incorrect. Connection draining can only be configured on a load balancer. Cloud Armor is just a distractor.
- Option B is incorrect Connection draining can only be configured on a load balancer.
- Option C is correct. Connection draining is a process that ensures that existing, in-progress requests are given time to complete when a VM is removed from an instance group. The connection draining timeout specifies the time to be given to requests to complete before the VM is removed from the load balancer.
- Option D is incorrect. Connection draining can only be configured on a load balancer.
