Question #: 136
Topic #: 1
[All Professional Cloud Network Engineer Questions]

You are designing a hub-and-spoke network architecture for your company’s cloud-based environment. You need to make sure that all spokes are peered with the hub. The spokes must use the hub's virtual appliance for internet access. The virtual appliance is configured in high-availability mode with two instances using an internal load balancer with IP address 10.0.0.5. What should you do?

  • A. 1. Create a default route in the hub VPC that points to IP address 10.0.0.5.
    2. Delete the default internet gateway route in the hub VPC, and create a new higher-priority route that is tagged only to the appliances with a next hop of the default internet gateway.
    3. Export the custom routes in the hub.
    4. Import the custom routes in the spokes.
  • B. 1. Create a default route in the hub VPC that points to IP address 10.0.0.5.
    2. Delete the default internet gateway route in the hub VPC, and create a new higher-priority route that is tagged only to the appliances with a next hop of the default internet gateway.
    3. Export the custom routes in the hub. Import the custom routes in the spokes.
    4. Delete the default internet gateway route of the spokes.
  • C. 1. Create two default routes in the hub VPC that point to the next hop instances of the virtual appliances.
    2. Delete the default internet gateway route in the hub VPC, and create a new higher-priority route that is tagged only to the appliances with a next hop of the default internet gateway.
    3. Export the custom routes in the hub. Import the custom routes in the spokes.
  • D. 1. Create a default route in the hub VPC that points to IP address 10.0.0.5.
    2. Delete the default internet gateway route in the hub VPC, and create a new higher-priority route that is tagged only to the appliances with a next hop of the default internet gateway.
    3. Create a new route in the spoke VPC that points to IP address 10.0.0.5.

I think is B, export and import when configured peering btw hub-spoke, and delete default route in spoke.

Selected Answer: B
Option B is the correct answer because it correctly sets up routing between the hub and spokes and ensures all spoke traffic to the internet passes through the virtual appliance in the hub. Deleting the default route in the spokes is necessary to ensure they don’t bypass the hub and connect to the internet directly.

Selected Answer: A
Deleting the default internet gateway route in the spokes would have communication issues with the hub. Also we need to export custom routes from the hub and then import them into the spokes to propagate the routing configuration

The Answer is a A: I'm suspect on deleting default internet route on spokes. Can cause issues.

B. 1. Create a default route in the hub VPC that points to IP address 10.0.0.5. 2. Delete the default internet gateway route in the hub VPC, and create a new higher-priority route that is tagged only to the appliances with a next hop of the default internet gateway. 3. Export the custom routes in the hub. Import the custom routes in the spokes. 4. Delete the default internet gateway route of the spokes. Example architecture using VPC Network Peering and internal TCP/UDP load balancer as next hop This architecture is a typical use case for enterprise environments, using the internal TCP/UDP load balancer for high availability, combined with VPC Network Peering for attaching network segments. The default route to the internet gateway in the spoke ***** VPC networks is deleted.
