Updated On: 10-Feb-2026



Refer to the exhibit. The full EIGRP routing table is advertised throughout the network. Currently, users experience data loss when any one link in the network fails. An architect must optimize the network to reduce the impact when a link fails. Which solution should the architect include in the design?

  1. Run BFD on the inter links between EIGRP neighbors.
  2. Summarize the access layer networks from each access layer switch toward the aggregation layer.
  3. Reduce the default EIGRP hello interval and hold time.
  4. Summarize the access layer networks from the aggregation layer toward the core layer.

Answer(s): D



What is the purpose of a control plane node in a Cisco SD-Access network fabric?

  1. to maintain the endpoint database and mapping between endpoints and edge nodes
  2. to detect endpoints in the fabric and inform the host tracking database of EID-to-fabric-edge node bindings
  3. to identify and authenticate endpoints within the network fabric
  4. to act as the network gateway between the network fabric and outside networks

Answer(s): A





Refer to the exhibit. An architect reviews the low-level design of a company's enterprise network and advises optimizing the STP convergence time.
Which functionality must be applied to Gi1/0/1-10 to follow the architect's recommendation?

  1. UplinkFast
  2. root guard
  3. BPDU guard
  4. PortFast

Answer(s): D



An engineer must design a large Layer 2 domain that contains hundreds of switches and VLANs. The engineer's primary goals are to:
Efficiently utilize the bandwidth of all links

Avoid Layer 2 loops

Cause minimal impact on switch CPU and memory

Which technology should the engineer include in the design?

  1. MST
  2. Rapid PVST+
  3. RSTP
  4. PVST+

Answer(s): A





Refer to the exhibit. An engineer must design an automatic failover solution. The solution should allow HSRP to detect a WAN 1 failure and initiate an automatic failover, making router R2 the active HSRP router. Which two solutions should the engineer choose? (Choose two.)

  1. implement IP SLA on router R1
  2. implement PBR on router R1
  3. implement Enhanced Object Tracking on router R1
  4. use IP source routing
  5. use a floating static route

Answer(s): A,C
