Google Professional Cloud Network Engineer Question 630
Select 3Google Cloud PlatformYour organization requires a high-bandwidth, low-latency connection between your on-premises data center and your workloads running in Google Cloud. You decide to use Dedicated Interconnect. After provisioning the interconnect, what steps must you take to establish connectivity to your VPC network?
- A
Create a VLAN attachment (also known as an interconnect attachment) in the same region as your VPC.
- B
Configure the BGP session to exchange routes between your on-premises router and Google Cloud.
- C
Assign an external IP address to the interconnect attachment for public internet connectivity.
- D
Attach the VLAN attachment to a Cloud VPN gateway for encryption of traffic.
- E
Verify that the VLAN attachment and interconnect are in a 'provisioned' state before using them.
Show answer and explanation
Correct answers: A, B, E
Explanation
To establish connectivity using Dedicated Interconnect, you must create VLAN attachments in the same region as your VPC and configure BGP for route exchange. Additionally, verifying the state of the interconnect and VLAN attachments ensures they are operational before use. Assigning external IPs or attaching VLAN attachments to a Cloud VPN gateway are not required or supported for this scenario.
- A. Correct.
Correct: A VLAN attachment is required to connect your Dedicated Interconnect to your VPC network. The attachment must be created in the same region as your VPC.
- B. Correct.
Correct: Configuring a Border Gateway Protocol (BGP) session is necessary for route exchange between your on-premises network and Google Cloud.
- C. Incorrect.
Incorrect: Dedicated Interconnect does not use public internet connectivity, so assigning an external IP address is unnecessary and irrelevant.
- D. Incorrect.
Incorrect: VLAN attachments do not require or support attachment to a Cloud VPN gateway. Dedicated Interconnect provides private connectivity, and encryption is typically managed separately, if needed.
- E. Correct.
Correct: Before using the interconnect and VLAN attachments, it is essential to ensure that they are in a 'provisioned' state, indicating that they are ready for traffic.
