Show answer and explanation
Correct answers: A, B, D
Explanation
To establish connectivity using a Dedicated Interconnect, you must reserve a VLAN attachment in the correct region and associate it with a Cloud Router. The Cloud Router handles dynamic routing via BGP. VLAN tagging ensures traffic is properly routed between networks, so the on-premises router must be configured with the correct VLAN ID. Public IPs and VPC flow logs are unrelated to this setup.
- A. Correct.
Correct. Reserving a VLAN attachment in the desired region and associating it with a Cloud Router is a necessary step to establish the connection.
- B. Correct.
Correct. Configuring a BGP session on the Cloud Router is required for dynamic routing between the on-premises network and Google Cloud.
- C. Incorrect.
Incorrect. VLAN attachments do not require a public IP address; they operate over private connections.
- D. Correct.
Correct. Provisioning a VLAN ID on the on-premises router that matches the VLAN ID of the attachment ensures proper tagging and routing of traffic.
- E. Incorrect.
Incorrect. While enabling VPC flow logs is useful for monitoring, it is not required to configure the VLAN attachment or establish connectivity.
