Google Professional Cloud Network Engineer Question 644
Select 4Google Cloud PlatformYour organization is using a multi-cloud strategy and needs to establish a high-speed, low-latency connection between Google Cloud and resources in another cloud provider. You are tasked with creating a Cross-Cloud Interconnect connection and configuring VLAN attachments. Which of the following steps should you take to achieve this setup?
- A
Provision a Dedicated Interconnect or Partner Interconnect connection in Google Cloud for connectivity to the other cloud provider.
- B
Create a VLAN attachment in Google Cloud and associate it with the Interconnect for traffic segregation.
- C
Configure a Cloud Router to handle the dynamic routing between Google Cloud and the other cloud provider.
- D
Configure a VPN tunnel on both sides to complement the Cross-Cloud Interconnect for redundancy.
- E
Enable the Direct Peering option in Google Cloud to establish the connection.
- F
Set up appropriate IAM permissions to allow network administrators to manage VLAN attachments.
Show answer and explanation
Correct answers: A, B, C, F
Explanation
To set up a Cross-Cloud Interconnect connection, you need to provision an Interconnect connection (either Dedicated or Partner), configure VLAN attachments to link this connection to your VPC, and use a Cloud Router to manage dynamic routing. Proper IAM permissions are essential for managing these resources. VPN tunnels and Direct Peering are not mandatory for this setup but may be considered for redundancy or other use cases.
- A. Correct.
Correct: Setting up a Dedicated Interconnect or Partner Interconnect is the first step to establish physical connectivity between Google Cloud and the other cloud provider.
- B. Correct.
Correct: VLAN attachments are necessary to segregate traffic for different workloads or environments and to link the Interconnect to your VPC network.
- C. Correct.
Correct: A Cloud Router is required to dynamically exchange routes between Google Cloud and the other cloud provider, ensuring proper routing.
- D. Incorrect.
Incorrect: While VPN tunnels can provide redundancy, they are not a required step for setting up Cross-Cloud Interconnect connections. They are an optional consideration for failover scenarios.
- E. Incorrect.
Incorrect: Direct Peering is not used in Cross-Cloud Interconnect setups. It is a separate type of connectivity for connecting on-premises networks directly to Google.
- F. Correct.
Correct: IAM permissions must be configured to allow network administrators to manage VLAN attachments and other network resources effectively.
