Match each high availability or redundancy concept on the left with its correct operational description on the right.
- Hot Standby Router Protocol (HSRP)A Cisco-proprietary first-hop redundancy protocol that elects an Active and Standby router to manage a virtual gateway.
- Link Aggregation Control Protocol (LACP)An open-standard protocol (IEEE 802.3ad) that dynamically combines multiple physical Ethernet links into a single logical channel.
- Virtual Router Redundancy Protocol (VRRP)An open-standard first-hop redundancy protocol that allows a group of routers to present a single virtual IP address to local hosts.
- Active-Passive ClusteringA redundancy model where a secondary system remains idle in standby mode until the primary active node experiences a failure.
Cevap
The correct match pairs Hot Standby Router Protocol (HSRP) with the Cisco-proprietary first-hop redundancy protocol definition; Link Aggregation Control Protocol (LACP) with the IEEE 802.3ad open-standard multi-link bundling protocol; Virtual Router Redundancy Protocol (VRRP) with the open-standard default gateway redundancy protocol; and Active-Passive Clustering with the architecture where a secondary unit remains idle until primary failure.
Each concept directly matches its fundamental operational definition. HSRP is Cisco-proprietary for first-hop gateway failover, VRRP is an open-standard gateway redundancy protocol, LACP provides IEEE 802.3ad link bundling at Layer 2, and Active-Passive clustering reserves a secondary system for automated failover during active node failure.
