Google Professional Cloud Network Engineer Question 634
Select 3Google Cloud PlatformYour organization needs to establish a high-throughput, low-latency connection between its on-premises data center and Google Cloud. You've decided to use Dedicated Interconnect to achieve this. After provisioning the Dedicated Interconnect, you are tasked with configuring VLAN attachments to connect your on-premises network to a VPC network in Google Cloud. Which of the following steps are required to configure VLAN attachments correctly?
- A
Create a Cloud Router in the same region as the VLAN attachment.
- B
Select an existing Cloud VPN connection for the VLAN attachment.
- C
Specify an IP address range for the BGP session when creating the VLAN attachment.
- D
Associate the VLAN attachment with a Dedicated Interconnect connection.
- E
Enable Private Google Access on the subnet used for the VLAN attachment.
Show answer and explanation
Correct answers: A, C, D
Explanation
To configure VLAN attachments for a Dedicated Interconnect connection, you must use a Cloud Router to manage dynamic routing via BGP. During the VLAN attachment creation process, you must specify an IP address range for the BGP session and associate the attachment with the Dedicated Interconnect connection. Cloud VPN is unrelated to this process, and enabling Private Google Access is not a requirement for VLAN attachment configuration.
- A. Correct.
Correct. A Cloud Router is required to manage dynamic routing via BGP for the VLAN attachment. It must be in the same region as the VLAN attachment.
- B. Incorrect.
Incorrect. Cloud VPN is not used with VLAN attachments for Dedicated Interconnect. VLAN attachments are specific to Dedicated Interconnect setups.
- C. Correct.
Correct. When creating a VLAN attachment, you must specify the IP address range for the BGP session, which is used for route advertisement.
- D. Correct.
Correct. VLAN attachments must be explicitly associated with a Dedicated Interconnect connection to link the on-premises network to the VPC network.
- E. Incorrect.
Incorrect. Enabling Private Google Access is not mandatory for configuring VLAN attachments. It is used to allow private IP access to Google APIs and services from a subnet.
