Question 51

When vEdge router redundancy is designed, which FHRP is supported?

  1. HSRP
  2. OMP
  3. GLBP
  4. VRRP

Question 52

What is the purpose of an edge node in an SD-Access network fabric?

  1. Edge nodes identify and authenticate endpoints and register endpoint information with control plane nodes.
  2. Edge nodes track endpoint IDs to location mappings, along with IPv4, IPv6, or MAC addresses.
  3. Edge nodes are the gateway between the fabric domain and network outside of the fabric.
  4. Edge nodes resolve lookup requests from edge and border nodes to locate destination endpoint IDs.

Question 53

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?

  1. Cisco Application Policy Infrastructure Controller Enterprise Module
  2. Cisco Network Data Platform
  3. Cisco Identity Services Engine
  4. Cisco TrustSec

Question 54

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

  1. PIM SSM must run in the underlay.
  2. Multicast clients reside in the underlay, and the multicast source is outside the fabric or in the overlay.
  3. Rendezvous points must be used in a PIM SSM deployment.
  4. Multicast traffic is transported in the overlay and the EID space for wired and wireless clients.

Question 55

What is the role of a control-plane node in a Cisco SD-Access architecture?

  1. fabric device that connects wired endpoints to the SD-Access fabric
  2. map system that manages endpoint to device relationships
  3. fabric device that connects APs and wireless endpoints to the SD-Access fabric
  4. map system that manages External Layer 3 networks
