  B. Configure distribution layer switches to summarize routes to the core layer.
  C. Configure access layer switches as stub routers.
  D. Configure access layer and core layer switches as stub routers.
  E. Configure access layer switches to summarize routes to the distribution layer.
  B. Configure distribution layer switches to summarize routes to the core layer.
  C. Configure access layer switches as stub routers.

• Question 184:

  Which method will filter routes between EIGRP neighbors within the same autonomous system?

  A. distribute-list
  B. policy-based routing
  C. leak-map
  D. route tagging
  A. distribute-list

• Question 185:

  Refer to the exhibit.

  C. Cisco WAN Edge routers are configured with all Orchestrators using their IP addresses and priority.
  D. A single Cisco Orchestrator is deployed in each network.
  A. The IP addresses of all Orchestrators are mapped to a single DNS name.

• Question 187:

  Refer to the exhibit

  A. VDC
  B. VSS
  C. Etherchannel
  D. Stackwise
  D. Stackwise
