Network

Because of a major version change, an engineer must upgrade software on a Cisco Nexus Series switch.

Which two technologies should be implemented to minimize network disruption during the upgrade?

Choose two
  • A vPC
  • B HSRP
  • C VDC
  • D MLAG
  • E PAgP
Explanation

vPC provides redundant Layer 2 forwarding across two Cisco Nexus peer switches, so traffic can continue through the available peer while the other switch is reloaded for the upgrade. HSRP provides redundant Layer 3 default-gateway service, allowing gateway forwarding to fail over when the active switch is unavailable.
