Google Professional Cloud Network Engineer Question 629
Select 3Google Cloud PlatformYour company is planning to use a Dedicated Interconnect to establish a high-speed, low-latency connection between its on-premises data center and Google Cloud. As part of the setup, you are tasked with planning the configuration of the Interconnect. Which of the following considerations should you account for during this setup?
- A
Ensure that the on-premises router supports BGP and has a public ASN or private ASN within the supported range.
- B
Verify that your organization has a colocation facility that connects directly to a Google edge point of presence (PoP).
- C
Configure a Cloud Router in the same region as the resources you plan to connect to the Interconnect.
- D
Select a VLAN attachment size that matches the exact bandwidth of your Dedicated Interconnect.
- E
Ensure that the Dedicated Interconnect is deployed in a single region for cost optimization.
Show answer and explanation
Correct answers: A, B, C
Explanation
When configuring a Dedicated Interconnect, it is crucial to ensure compatibility with BGP, establish a connection through a colocation facility that links to a Google edge PoP, and configure a Cloud Router in the same region as your resources. These steps ensure proper routing and connectivity. VLAN attachment sizes can vary and do not need to match Interconnect bandwidth exactly. Additionally, deploying the Interconnect in a single region is not a best practice for redundancy or availability.
- A. Correct.
Correct. BGP (Border Gateway Protocol) is required for routing over Interconnect, and the ASN must meet the requirements set by Google Cloud.
- B. Correct.
Correct. A colocation facility connected to a Google edge PoP is essential for establishing the physical connection of a Dedicated Interconnect.
- C. Correct.
Correct. The Cloud Router must be in the same region as the resources being accessed to manage BGP sessions and route traffic effectively.
- D. Incorrect.
Incorrect. VLAN attachment sizes do not need to match the exact bandwidth of a Dedicated Interconnect. You can configure multiple VLAN attachments with different bandwidths on a single Interconnect.
- E. Incorrect.
Incorrect. Deploying a Dedicated Interconnect in a single region is not a requirement and may not align with best practices for availability or performance.
