2. Question 332 · 382 in bank

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

   • AWAN Edge devices advertise the rendezvous point to all the receivers through the overlay network.
   • BWAN Edge devices advertise the rendezvous point to all the receivers through the underlay network.
   • CvSmart Controllers advertise the rendezvous point to all the receivers through the overlay network.
   • DvSmart Controllers advertise the rendezvous point to all the receivers through the underlay network.

   Show answer

   Answer: C

   Explanation

   https://www.cisco.com/c/en/us/td/docs/routers/sdwan/configuration/routing/vEdge-20-x/routing-book/m-multicast-routing.html 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. so IMHO, answer C is correct.

4. Question 334 · 382 in bank

   

   Refer to the exhibit. Which configuration value is used to change the administrative distance of iBGP routes to 20?

   • AConfigure Internal Routes Distance to 20.
   • BConfigure Propagate AS Path to off.
   • CConfigure Local Routes Distance to 20.
   • DConfigure External Routes Distance to 20.

   Show answer

   Answer: C

   Explanation

   nop, do not let the "internal routes" confuse you. the description says " - for routes coming from one AS into another-", if you recall your BGP, eBGP (external ) is from one AS to an other. if the routes are within the same AS , it is iBGP (internal routes). in vManage the description for local routes = iBGP

5. Question 335 · 382 in bank

   How is multicast routing enabled on devices in the Cisco SD-WAN overlay network?

   • AThe WAN Edge routers originate multicast service routes to the vSmart controller via OMP, which then forwards joins for requested multicast groups based on IGMP v2 or v3 toward the source or PIM-RP as specified in the original PIM join message.
   • BThe WAN Edge routers originate multicast service routes to the vSmart controller via OMP, which then forwards joins for requested multicast groups based on IGMP v1 or v2 toward the source or PIM-RP as specified in the original PIM join message.
   • CThe vSmart controller originates multicast service routes to the WAN Edge routers via OMP, which then forwards joins for requested multicast groups based on IGMP v1 or v2 toward the source or PIM-RP as specified in the original PIM join message.
   • DThe vSmart controller originates multicast service routes to the WAN Edge routers via OMP, which then forwards joins for requested multicast groups based on IGMP v2 or v3 toward the source or PIM-RP as specified in the original PIM join message.
