• Question 153:

  How does the replicator role function in cisco SD-WAN?

  A. WAN Edge devices advertise the rendezvous point to all the receivers through the underlay network.
  B. vSmart Controllers advertise the rendezvous point to all the receivers through the overlay network.
  C. WAN Edge devices advertise the rendezvous point to all receivers through the overlay network.
  D. vSmart Controllers advertise the rendezvous point to all the receivers through the underlay network.
  B. vSmart Controllers advertise the rendezvous point to all the receivers through the overlay network.

  For efficient use of WAN bandwidth, strategic Cisco SD-WAN routers can be deployed and configured as replicators throughout the overlay network. Replicators mitigate the requirement for a Cisco SD-WAN router with local sources or the PIM-RP to replicate a multicast stream once for each receiver. As discussed above, replicators advertise themselves, using OMP multicast-autodiscover routes, to the Cisco vSmart Controllers in the overlay network. The controllers then forward the replicator location information to the PIM-enabled Cisco IOS XE SD-WAN routers that are in the same VPN as the replicator.

• Question 154:

  Refer to the exhibit.

  B. Configure Propagate AS Path to off.
  C. Configure Local Routes Distance to 20.
  D. Configure External Routes Distance to 20.
  C. Configure Local Routes Distance to 20.

• Question 156:

  In the Cisco SD-WAN solution, vSmart controller is responsible for which two actions? (Choose two)

  A. Authenticate and authorize vEdge routers.
  B. Distribute the IP address from DHCP server to vEdge routers
  C. Distribute crypto key information among vEdge routers
  D. Configure and monitor vEdge routers
  E. Distribute route and policy information via OMP.
  C. Distribute crypto key information among vEdge routers
  E. Distribute route and policy information via OMP.

• Question 157:

  

  Refer to the exhibit Which configuration ensures that OSPF routes learned from Site2 are reachable at Sitel and vice-versa?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  D. Option D

• Question 158:

  A voice packet requires a latency of 50 msec. Which policy is configured to ensure that a voice packet is always sent on the link with less than a 50 msec delay?

  A. localized data policy
  B. centralized control policy
  C. localized control policy
  D. centralized data policy
  D. centralized data policy

  ---

  Centralized data policies allow you to define rules and conditions for application-aware routing, QoS (Quality of Service), and traffic optimization. In this case, you would set up the policy to prioritize voice traffic and select the link with a delay of less than 50 milliseconds as the preferred path for voice packets. https://www.cisco.com/c/en/us/td/docs/routers/sdwan/configuration/policies/ios-xe-17/policies-book-xe/application-aware-routing.html

• Question 159:

  Refer to the exhibit.

  

  A network administrator is configuring OSPF advanced configuration parameters from a template using the vManage GUI for a branch WAN Edge router to calculate the cost of summary routes to an ASBR.. Which action achieves this configuration?

  A. Enable Originate.
  B. Disable RFC 1583 Compatible.
  C. Disable Originate.
  D. Enable RFC 1583 Compatible.
  A. Enable Originate.

  ---

  To configure OSPF advanced configuration parameters in the vManage GUI for a branch WAN Edge router to calculate the summary routes to an ASBR, you should select "Enable Originate." Enabling Originate allows the router to advertise summary routes into the OSPF domain.

• Question 160:

  Which two actions are necessary to set the Controller Certificate Authorization mode to indicate a root certificate? (Choose two.)

  A. Select a private certificate signing authority instead of a public certificate signing authority.
  B. Change the organization name of the Cisco SD-WAN fabric.
  C. Select the Controller Certificate Authorization mode that is recommended by Cisco.
  D. Upload an SSL certificate to vManage.
  E. Select a validity period from the drop-down menu.
  A. Select a private certificate signing authority instead of a public certificate signing authority.
  D. Upload an SSL certificate to vManage.
