Google Professional Cloud Network Engineer Question 115
Single answerGoogle Cloud PlatformA company needs to establish a reliable and high-bandwidth connection between their on-premises datacenter and their Virtual Private Cloud (VPC) in Google Cloud. The on-premises network requires a minimum of 5 Gbps throughput, and the company prefers a solution that minimizes latency while ensuring highly available connectivity. Which option would best meet the company's requirements?
- A
Use a Dedicated Interconnect with a 10 Gbps connection and configure redundant connections.
- B
Use a Partner Interconnect with a 50 Mbps connection through a third-party service provider.
- C
Use Cloud VPN in a high-availability configuration with multiple tunnels.
- D
Use a Dedicated Interconnect with a 1 Gbps connection and no redundancy.
Show answer and explanation
Correct answer: A
Explanation
The correct answer is to use a Dedicated Interconnect with a 10 Gbps connection and configure redundant connections. Dedicated Interconnect provides the high bandwidth and low latency required by the company's on-premises datacenter, and redundancy ensures the connection remains highly available. Other options either fail to meet the bandwidth requirement, introduce additional latency, or lack redundancy.
- A. Correct.
This option is correct because Dedicated Interconnect provides high-bandwidth, low-latency connectivity directly to Google Cloud. A 10 Gbps connection exceeds the minimum requirement of 5 Gbps, and redundancy ensures high availability.
- B. Incorrect.
This option is incorrect because Partner Interconnect does not meet the bandwidth requirement of 5 Gbps when using a 50 Mbps connection. Additionally, relying on a single connection through a third-party provider could introduce latency and reliability concerns.
- C. Incorrect.
This option is incorrect because while Cloud VPN can provide secure connectivity, it does not meet the 5 Gbps bandwidth requirement, even in a high-availability configuration.
- D. Incorrect.
This option is incorrect because a 1 Gbps Dedicated Interconnect does not meet the bandwidth requirement of 5 Gbps, and the lack of redundancy does not satisfy the high availability requirement.
