Practice Test 1 | Google Cloud Certified Professional Cloud Network Engineer | Dumps | Mock Test
You are the network engineer on the team testing a new application that will be deployed behind a load balancer. The team wants to ensure that multiple requests from a given user should be directed to the same backend based on the Header field (HEADER_FIELD) of the packets.
What should you do?
A. Enable connection draining on the load balancer and configure the connection draining timeout
B. Select the HTTP(S) load balancer and enable session affinity
C. Select the Network load balancer and enable session affinity
D. Enable session affinity on the GCP VPC and use any external-facing load balancer
Correct Answer: B
- Option A is incorrect. Connection draining does not help meet the requirement of sending multiple requests from a given user to the same backend. Connection draining is a process that ensures that existing, in-progress requests are given time to complete
- Option B is correct. Session affinity is used to deliver requests to the same backend that served the initial request. The HTTP(s) load balancer supports the use of the HEADER_FIELD session affinity option specified in the requirements.
- Option C is incorrect. The Network load balancer does not support the use of the HEADER_FIELD session affinity option specified in the requirements.
- Option D is incorrect. Session affinity is configured on the load balancer and not VPC. Also, not all load balancers support the use of the HEADER_FIELD session affinity option specified in the requirements.
