Google Professional Cloud Network Engineer Question 109
Select 3Google Cloud PlatformYou are designing a hybrid and multi-cloud network for a global organization that requires high availability, low latency, and fault tolerance. The organization operates workloads across Google Cloud, another public cloud provider, and an on-premises data center. Which of the following design considerations should you implement to ensure a resilient and performant network?
- A
Implement a dedicated interconnect or partner interconnect to connect the on-premises data center to Google Cloud.
- B
Use Cloud VPN as the primary connection between Google Cloud and other public cloud providers for low-latency requirements.
- C
Leverage Google Cloud's Network Service Tiers and use the Premium Tier for global traffic optimization.
- D
Set up BGP routing with dynamic routing enabled between the on-premises network, Google Cloud, and the other public cloud provider.
- E
Configure multi-region Cloud NAT to ensure outbound traffic is properly routed without exposing private IP addresses.
Show answer and explanation
Correct answers: A, C, D
Explanation
To design a resilient and performant hybrid and multi-cloud network, it is crucial to leverage high-performance connectivity options like dedicated interconnects, optimize traffic routing using Google Cloud's Premium Tier, and enable dynamic routing with BGP to ensure failover and route optimization. Cloud VPN and Cloud NAT, while valuable for specific use cases, are not ideal for high-performance or fault-tolerant designs.
- A. Correct.
Implementing a dedicated interconnect or partner interconnect provides high-bandwidth, low-latency connectivity between the on-premises data center and Google Cloud, which is essential for hybrid environments.
- B. Incorrect.
Cloud VPN is not suitable for low-latency or high-performance requirements as it relies on public internet paths, which can introduce higher latency and less reliability compared to dedicated solutions.
- C. Correct.
Google Cloud's Premium Tier routes traffic over Google's high-performance global network, optimizing latency and performance for workloads spread across multiple regions or clouds.
- D. Correct.
Using BGP with dynamic routing allows automatic failover and route optimization between the on-premises network, Google Cloud, and other public clouds, which is critical for fault tolerance and resiliency.
- E. Incorrect.
Multi-region Cloud NAT is primarily used for managing outbound traffic and does not contribute directly to the goals of network resiliency, low latency, or fault tolerance in a hybrid or multi-cloud setup.
