Google Professional Cloud Network Engineer Question 665

Select 3Google Cloud Platform

You are tasked with setting up a Classic VPN between your Google Cloud Virtual Private Cloud (VPC) and an on-premises network. The on-premises network administrator has provided you with the necessary IP ranges and a shared key. The requirement is to ensure that the VPN connection is route-based. Which of the following steps should you take to configure the Classic VPN correctly?

  1. A

    Create a Cloud VPN gateway in your VPC and specify a target VPN gateway on the on-premises side.

  2. B

    Use static routes to manually define the IP ranges reachable through the VPN tunnel.

  3. C

    Set up a VPN tunnel and select 'Policy-based routing' as the routing option.

  4. D

    Set up a VPN tunnel and select 'Dynamic (BGP)' as the routing option.

  5. E

    Configure Cloud Router for the VPN gateway to dynamically exchange routes with the on-premises network using BGP.

Show answer and explanation

Correct answers: A, D, E

Explanation

To configure a Classic VPN with a route-based setup, you must create a Cloud VPN gateway, configure the VPN tunnel with dynamic routing using BGP, and set up a Cloud Router to exchange routes dynamically between your Google Cloud VPC and the on-premises network. Policy-based routing is not applicable to route-based VPNs, and static routes are not necessary when using BGP for dynamic routing.

  • A. Correct.

    Correct: Creating a Cloud VPN gateway is a required initial step to establish the Classic VPN connection.

  • B. Incorrect.

    Incorrect: Static routes are not required for a route-based VPN connection, as dynamic routing using BGP is preferred for this configuration.

  • C. Incorrect.

    Incorrect: Policy-based routing is not used for route-based VPN connections. Route-based VPN connections require either static or dynamic routing, typically using BGP.

  • D. Correct.

    Correct: For a route-based VPN, you must configure the tunnel and select 'Dynamic (BGP)' as the routing option.

  • E. Correct.

    Correct: A Cloud Router is required to enable dynamic route exchange using BGP, which is essential for route-based VPN configurations.
