Which solution allows overlay VNs to communicate with each other in an SD-WAN Architecture?

An engineer is designing a multicast network for a financial application. Most of the multicast sources also receive multicast traffic (many-to-many deployment model). To better scale routing tables, the design must not use source trees. Which multicast protocol satisfies these requirements?

Which PIM mode uses a shared tree only?

Which design element should an engineer consider when multicast is included in a Cisco SD-Access architecture?

A client is moving to Model-Driven Telemetry and requires periodic updates. What must the network architect consider with this design?

An infrastructure team is concerned about the shared memory utilization of a device, and for this reason, they need to monitor the device state. Which solution limits impact on the device and provides the required data?

A company with multiple service providers wants to speed up BGP convergence time in the event a failure occurs with their primary link. Which approach achieves this goal and does not impact router CPU utilization?

Which two steps can be taken to improve convergence in an OSPF network? (Choose two.)

Refer to the exhibit. EIGRP has been configured on all links. The spoke nodes have been configured as EIGRP stubs, and the WAN links to R3 have higher bandwidth and lower delay than the WAN links to R4. When a link failure occurs at the R1-R2 link, what happens to traffic on R1 that is destined for a subnet attached to R2?

Which design consideration must be made when using IPv6 overlay tunnels?

An engineer is working for a large cable TV provider that requires multiple sources streaming video on different channels using multicast with no rendezvous point.
Which multicast protocol meets these requirements?

How do endpoints inside an SD-Access network reach resources outside the fabric?

Which two border nodes are available in the Cisco SD-Access architecture? (Choose two.)

An engineer is upgrading a company's main site to include a connection to a second ISP. The company will receive full Internet routing tables from both ISPs via
BGP. The engineer must ensure that the company does not become a transit autonomous system. Which solution should be included in this design?

Which control-plane technology allows the same subnet to exist across multiple network locations?

In an SD-WAN architecture, which methods are used to bootstrap a vEdge router?

Which component of Cisco SD-Access integrates with Cisco DNA Center to perform policy segmentation and enforcement through the use of security group access control lists and security group tags?

An organization is designing a detailed QoS plan that limits bandwidth to specific rates. Which two parameters are supported by the traffic policing feature?
(Choose two.)

Which design consideration should be observed when EIGRP is configured on Data Center switches?

A network solution is being designed for a company that connects to multiple Internet service providers. Which Cisco proprietary BGP path attribute will influence outbound traffic flow?

A company is using OSPF between its HQ location and a branch office. HQ is assigned area 0 and the branch office is assigned area 1. The company purchases a second branch office, but due to circuit delays to HQ, it decides to connect the new branch office to the existing branch office as a temporary measure. The new branch office is assigned to area 2. Which OSPF configuration enables all three locations to exchange routes?

Refer to the exhibit. Which solution decreases the EIGRP convergence time?

Which QoS feature responds to network congestion by dropping lower priority packets?

Which design consideration must be made when dual WAN Edge routers are deployed at a branch site?
