Google Professional Cloud Network Engineer Question 695
Select 2Google Cloud PlatformYou are designing a hybrid network architecture for a company that needs to securely connect their on-premises data center to Google Cloud. The company wants low-latency connectivity for critical applications and a redundant connection for high availability. Which combination of hybrid spokes would best meet these requirements?
- A
Use Dedicated Interconnect for primary connectivity and Partner Interconnect as a backup.
- B
Use a single Dedicated Interconnect connection for both primary and backup connectivity.
- C
Use a VPN tunnel for primary connectivity and a Dedicated Interconnect for backup connectivity.
- D
Use Dedicated Interconnect with redundant connections in different edge availability domains.
- E
Use a single VPN tunnel as the sole connection to the on-premises data center.
Show answer and explanation
Correct answers: A, D
Explanation
To meet the company's requirements of low-latency connectivity and high availability, a combination of Dedicated Interconnect for primary connectivity and a backup solution is ideal. Dedicated Interconnect provides low-latency, high-bandwidth connections, making it suitable for critical applications. For redundancy, either Partner Interconnect or additional Dedicated Interconnect connections in different edge availability domains can be used. VPN is not ideal as it introduces higher latency and is less reliable for critical, low-latency applications.
- A. Correct.
This is a valid option because Dedicated Interconnect provides low-latency, high-bandwidth connectivity, and Partner Interconnect can be used as a backup for redundancy if configured properly.
- B. Incorrect.
This option is not recommended as a single Dedicated Interconnect connection lacks redundancy, which is crucial for high availability.
- C. Incorrect.
This option does not meet the low-latency requirement because VPN tunnels typically add higher latency compared to Dedicated Interconnect.
- D. Correct.
This is a valid option because using redundant Dedicated Interconnect connections in different edge availability domains ensures high availability and low latency.
- E. Incorrect.
This option is not suitable as a single VPN tunnel does not provide redundancy or the required low-latency connectivity.
