Explanation
To configure a Partner Interconnect connection and its VLAN attachments, you need to create a VLAN attachment in the appropriate region and associate it with a Cloud Router. A BGP session must be configured on the Cloud Router for dynamic routing, and the connection must be provisioned through the Partner's portal. Additionally, for successful BGP connectivity, the ASNs of the on-premises router and Cloud Router must match. IP addresses for VLAN attachments are automatically assigned by Google Cloud and do not require manual configuration.
- A. Correct.
Correct: A VLAN attachment (also called an Interconnect attachment) must be created in the appropriate region and associated with a Cloud Router to route traffic between the on-premises network and Google Cloud.
- B. Correct.
Correct: To enable dynamic routing, a BGP session must be configured on the Cloud Router for the VLAN attachment.
- C. Correct.
Correct: The Partner Interconnect connection must be provisioned using the Partner's portal as part of the setup process.
- D. Incorrect.
Incorrect: The IP address for the VLAN attachment is automatically assigned and not manually configured.
- E. Correct.
Correct: The BGP Autonomous System Numbers (ASNs) between the on-premises router and Cloud Router must match for BGP to establish connectivity.
