Google Professional Cloud Network Engineer Question 615
Select 3Google Cloud PlatformYou are designing a highly available routing solution for a multi-NIC VM that serves traffic over different network interfaces. You need to configure an internal load balancer as the next hop to ensure high availability and facilitate dynamic routing to the VM. Which steps should you take to achieve this configuration?
- A
Create a backend service and attach the multi-NIC VM as a backend instance.
- B
Configure a default route in the VPC to use the internal load balancer's IP address as the next hop.
- C
Create a forwarding rule to direct traffic to the internal load balancer.
- D
Enable dynamic routing in the VPC and configure the internal load balancer as the next hop for routing.
- E
Assign a static internal IP address to the internal load balancer.
Show answer and explanation
Correct answers: A, C, E
Explanation
To configure an internal load balancer as a next hop for highly available routing, you must first create the load balancer by defining a backend service and attaching the multi-NIC VM as a backend instance. A forwarding rule is required to direct traffic to the internal load balancer. Additionally, assigning a static internal IP address ensures consistent routing and availability. Dynamic routing is not applicable in this scenario, and VPC routes cannot directly point to the load balancer's IP.
- A. Correct.
Correct: To use an internal load balancer as a next hop, you need to create a backend service and attach the multi-NIC VM as a backend instance to the load balancer.
- B. Incorrect.
Incorrect: Routes in a VPC cannot directly use an internal load balancer's IP address as a next hop. Instead, the internal load balancer distributes traffic to the backend instances.
- C. Correct.
Correct: A forwarding rule is necessary to direct traffic to the internal load balancer, which will then distribute traffic to the backend VM.
- D. Incorrect.
Incorrect: Dynamic routing is not specifically used with internal load balancers as next hops. The internal load balancer itself provides high availability and routing to the backend.
- E. Correct.
Correct: Assigning a static internal IP address to the internal load balancer ensures consistent routing and high availability for traffic.
