Cisco Cloud OnRamp for IaaS is designed to simplify and optimize connectivity between on-premises locations, Cisco SD-WAN components, and public cloud environments like AWS. The key components and functionalities of Cisco Cloud OnRamp for IaaS in this scenario include:

Transit VPC: The transit AWS VPC serves as a hub, where the virtual SD-WAN routers are deployed. These SD-WAN routers are responsible for efficiently connecting the customer's on-premises network with resources in the AWS cloud. AWS Transit Gateway: The AWS Transit Gateway provides centralized routing and connectivity management for multiple Amazon VPCs, including the transit VPC and other VPCs within the AWS environment. It simplifies and streamlines the routing of traffic between the VPCs and the on-premises network.

Site-to-Site IPsec Tunnels: Site-to-site IPsec tunnels are used to secure the communication between the SD-WAN routers in the transit VPC and the AWS Transit Gateway, ensuring the confidentiality and integrity of data in transit.

Correct Answer: B

In a Cisco SD-WAN network, multicast traffic management is handled differently compared to traditional IP multicast methods due to the nature of the overlay architecture. Multicast Service Routes: In Cisco SD-WAN, multicast receivers use the vSmart controller to request multicast streams. This is done via multicast service routes which the vSmart controller manages. The vSmart controller is responsible for maintaining and distributing multicast routing information to all edge devices in the network.

Correct Answer: A

Each interface has eight queues on hardware vEdge routers, numbered from 0 to 7. Queue 0 is reserved and is used for both control traffic and low-latency queuing (LLQ) traffic. For LLQ, any class that is mapped to queue 0 must also be configured to use LLQ. All control traffic is transmitted. Queues 1 to 7 are available for data traffic.
