Show answer and explanation
Correct answers: B, C, E
Explanation
To set up a Partner Interconnect connection, you need to configure VLAN attachments, which involves associating them with a Cloud Router and ensuring that BGP is configured correctly to manage routing between your on-premises network and Google Cloud. Verifying the 'ACTIVE' state of the attachment is critical to ensure that the connection is ready for use. Static routing is not supported for VLAN attachments in Partner Interconnect scenarios.
- A. Incorrect.
Incorrect. The VLAN ID is not specified when creating the VLAN attachment. The pairing key is provided by the service provider, not specified by the user.
- B. Correct.
Correct. A Cloud Router is required to associate with the VLAN attachment to handle dynamic BGP routing.
- C. Correct.
Correct. Establishing a BGP session is necessary to exchange routing information between your on-premises router and Google Cloud via the Partner Interconnect.
- D. Incorrect.
Incorrect. VLAN attachments for Partner Interconnect require BGP for dynamic routing and do not support static routing.
- E. Correct.
Correct. The VLAN attachment must be in the 'ACTIVE' state to ensure proper connectivity and routing before testing.
