  1. The IP addresses of all Orchestrators are mapped to a single DNS name.
  2. The closest Orchestrator to each Cisco WAN Edge router is selected.
  3. Cisco WAN Edge routers are configured with all Orchestrators using their IP addresses and priority.
  4. A single Cisco Orchestrator is deployed in each network.

Answer(s): A

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

  1. Use BGP AS-path prepending to influence egress traffic and use MED to influence ingress traffic from the branch.
  2. HSRP priorities must match the OMP routing policy to prefer one WAN Edge over the other.
  3. Traffic must be symmetrical as it egresses the WAN Edges and returns from remote sites for DPI to function properly.
  4. Configure BFD between WAN Edge routers to detect sub-second link failures.

Answer(s): C



When IPsec VPNs are designed, what is a unique requirement if support for IP Multicast is required?

  1. encapsulation of traffic with GRE or VTI
  2. IPsec forwarding using transport mode
  3. additional bandwidth for headend
  4. IPsec forwarding using tunnel mode

Answer(s): A



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

  1. LISP
  2. VXLAN
  3. FabricPath
  4. ISE mobility services

Answer(s): A



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?

  1. Tag incoming routes from both ISPs with BGP community no-export.
  2. Lower the MED for updates sent to the secondary ISP.
  3. Use a route-map to prevent all prefixes from being advertised to either ISP.
  4. Modify the local-preference for routes incoming from the primary ISP.

Answer(s): A
