Question 133 of 169
Single answerYou 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?
A1. 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.
✓B1. 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.
C1. 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.
D1. 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.
