What protocol or technology uses a standby router to assume packet-forwarding responsibility if the active router fails?

  • EtherChannel
  • DTP
  • HSRP
  • VTP

Explanation: Hot Standby Router Protocol (HSRP) is a Cisco-proprietary protocol designed to provide first-hop redundancy. In an HSRP group, one router is elected as the active device to forward packets while another acts as the standby router. The standby router's function is to monitor the operational status of the active router and assume packet-forwarding responsibility immediately if the active router fails, ensuring high network availability for hosts.
