Google Professional Cloud Network Engineer Question 415
Select 3Google Cloud PlatformYou are tasked with setting up an external HTTP load balancer in Google Cloud to handle traffic for a web application. The load balancer must forward incoming HTTP requests to a backend service deployed across multiple regions. To ensure proper functionality, which of the following configurations must you apply when creating the forwarding rule?
- A
Set the forwarding rule's IP address to an external global IP address.
- B
Configure the forwarding rule with the 'HTTP' protocol.
- C
Use a regional forwarding rule since the backend service spans multiple regions.
- D
Associate the forwarding rule with a target HTTP proxy.
- E
Specify a backend instance group within the forwarding rule.
Show answer and explanation
Correct answers: A, B, D
Explanation
To configure a forwarding rule for an external HTTP load balancer, you must set a global IP address, specify the 'HTTP' protocol, and associate the rule with a target HTTP proxy. These configurations ensure that the load balancer can properly route incoming HTTP requests to the desired backend service. Regional forwarding rules and specifying backend instance groups in the forwarding rule are not applicable for this type of load balancer.
- A. Correct.
Correct. An external HTTP load balancer requires a global IP address to handle traffic from the internet.
- B. Correct.
Correct. The forwarding rule must specify the appropriate protocol, 'HTTP,' to handle web traffic.
- C. Incorrect.
Incorrect. For an external HTTP load balancer, you must use a global forwarding rule, not a regional one, because the backend service spans multiple regions.
- D. Correct.
Correct. A forwarding rule for an HTTP load balancer must be associated with a target HTTP proxy that defines how requests are routed.
- E. Incorrect.
Incorrect. Forwarding rules do not directly specify backend instance groups. Instead, the backend configuration is managed separately through backend services.
