Explanation:

Enable specifically at the network edge gt;STP Manually prune unused VLANs gt;Trunks

Use specifically on fiber-optic interconnections that link switches gt;UDLD

Ensure that an individual link failure will not result in an STP failure gt;Etherchannel

Always use a number of links that is a power of 2 (2, 4, 8) to optimize the load balancing of trafficgt; VSS

  1. multiple connections and FHRP

  2. HSRP and GLBP

  3. redundant supervisor and power supplies

  4. dual uplinks and switches

Answer: A Explanation:

Well, redundant supervisor could also be seen as resiliency at the hard amp; software (cause the control plane is taken over by the second sup if there is a failure on the first one)…

Again, those answers can be debated.

Which two options are two benefits of a Layer 2 looped model? (Choose two.)

  1. extends VLANs between switches that are connected to a common aggregation module

  2. prevents uplink ports from entering the spanning-tree blocking state

  3. provides quick convergence with Rapid Spanning Tree Protocol

  2. When redundant Layer 3 links, that are not part of a single EtherChannel or bundle, exist between distribution switches

  3. Between Distribution and Core switches when interfaces are configured with quot;no switchportquot;

  4. Between Distribution and Core switches when VSS is configured
