Google Professional Cloud Network Engineer Question 108
Select 4Google Cloud PlatformYou are designing a hybrid and multi-cloud network for a company that needs to ensure high availability and low latency for its global users. The company has services running in Google Cloud, AWS, and an on-premises data center. Which of the following design considerations would contribute to a resilient and performant network?
- A
Implementing Cloud Interconnect for dedicated high-speed connectivity between Google Cloud and the on-premises data center.
- B
Using Traffic Director to manage global traffic routing across Google Cloud, AWS, and the on-premises data center.
- C
Enabling VPC Network Peering between Google Cloud and AWS to connect the two environments.
- D
Deploying a multi-region load balancer in Google Cloud to distribute traffic across multiple Google Cloud regions.
- E
Configuring Border Gateway Protocol (BGP) sessions to establish dynamic routing between the on-premises data center and Google Cloud.
Show answer and explanation
Correct answers: A, B, D, E
Explanation
Designing a resilient and performant hybrid and multi-cloud network requires leveraging Google Cloud features like Cloud Interconnect for secure and high-speed connectivity to on-premises environments, Traffic Director for intelligent routing across cloud providers, and multi-region load balancers for global traffic distribution. Additionally, using BGP for dynamic routing ensures that the network can adjust to failures or changes dynamically, improving overall resiliency. VPC Network Peering, however, is not a suitable solution for connectivity across cloud providers.
- A. Correct.
Implementing Cloud Interconnect provides high-speed, low-latency, and secure connectivity between Google Cloud and the on-premises data center, which is essential for a performant hybrid network.
- B. Correct.
Traffic Director enables global load balancing and intelligent traffic routing across multiple clouds and on-premises environments, which ensures resiliency and optimal performance.
- C. Incorrect.
VPC Network Peering is not used to connect Google Cloud and AWS. Instead, it is used for connecting VPCs within Google Cloud. For hybrid and multi-cloud networks, other solutions like VPN or Interconnect are more appropriate.
- D. Correct.
A multi-region load balancer in Google Cloud ensures that traffic is distributed across multiple regions, improving availability and reducing latency for users globally.
- E. Correct.
Configuring BGP sessions allows for dynamic routing and failover between the on-premises data center and Google Cloud, which is critical for resiliency in hybrid networks.
