Show answer and explanation

Correct answers: B, D

Explanation

Protocol forwarding allows you to forward traffic directly to a backend instance using protocols not supported by Google Cloud Load Balancers. To configure protocol forwarding, you must create a target instance that specifies the backend instance, and you must ensure that the backend instance's firewall rules allow traffic on the required protocol and port. Health checks and HTTP(S) Load Balancers are not applicable in this scenario.

  • A. Incorrect.

    This option is incorrect because a forwarding rule must point to a target instance, not directly to a Compute Engine instance.

  • B. Correct.

    This option is correct because protocol forwarding requires the creation of a target instance to route traffic to the specified backend instance.

  • C. Incorrect.

    This option is incorrect because health checks are not required for protocol forwarding; they are typically used with load balancers.

  • D. Correct.

    This option is correct because the backend instance must have a firewall rule allowing traffic on the protocol and port being forwarded.

  • E. Incorrect.

    This option is incorrect because protocol forwarding is used for custom protocols not supported by HTTP(S) Load Balancers.
