Google Professional Cloud Network Engineer Question 106
Select 3Google Cloud PlatformYour organization is building a hybrid cloud environment that connects its on-premises data center to Google Cloud. You are tasked with designing a resilient and performant network that ensures low-latency connectivity and high availability. Which of the following design considerations should you prioritize?
- A
Implement Dedicated Interconnect or Partner Interconnect to establish a private and reliable connection.
- B
Leverage a single VPN tunnel for cost savings and simplicity.
- C
Use Cloud DNS for internal name resolution across on-premises and Google Cloud resources.
- D
Design for redundant Interconnects or VPN tunnels in different Google Cloud regions.
- E
Use public IPs for all hybrid communication to reduce complexity in routing.
Show answer and explanation
Correct answers: A, C, D
Explanation
To design a resilient and performant hybrid cloud network, it's critical to use private connectivity options such as Dedicated Interconnect or Partner Interconnect for reliability and low latency. Additionally, redundancy should be built into the design by using multiple Interconnects or VPN tunnels to ensure high availability. Cloud DNS helps with seamless internal name resolution, while public IPs and single VPN tunnels should be avoided due to performance, security, and resilience concerns.
- A. Correct.
Implementing Dedicated Interconnect or Partner Interconnect provides a private, high-bandwidth, and reliable connection between your on-premises and Google Cloud environments, which ensures better performance and security than using public internet-based connectivity.
- B. Incorrect.
Using a single VPN tunnel introduces a single point of failure and does not meet the requirements for resilience or high availability.
- C. Correct.
Cloud DNS allows for seamless internal name resolution across hybrid environments, which simplifies operation and improves performance in a hybrid setup.
- D. Correct.
Designing for redundant Interconnects or VPN tunnels in different Google Cloud regions ensures high availability by avoiding single points of failure and providing failover options.
- E. Incorrect.
Using public IPs for hybrid communication is not a recommended practice as it can introduce latency, security risks, and complexity in routing.
