Difficulty: EasyHigh Availability and Redundancy Concepts

Match each high availability technology or redundancy concept on the left to its correct operational description on the right.

  • HSRPCisco-proprietary first-hop redundancy protocol providing a virtual gateway IP address to local network hosts.
  • VRRPOpen-standard first-hop redundancy protocol enabling multiple routers to share a virtual gateway IP address.
  • LACPIEEE standard protocol (802.3ad/802.1AX) that dynamically aggregates multiple physical network links into a single logical channel.
  • Active-Passive ClusteringRedundancy configuration where a secondary standby device monitors the primary device and assumes processing only upon primary node failure.

Answer

HSRP pairs with Cisco-proprietary first-hop redundancy protocol providing a virtual gateway IP address to local network hosts; VRRP pairs with Open-standard first-hop redundancy protocol enabling multiple routers to share a virtual gateway IP address; LACP pairs with IEEE standard protocol (802.3ad/802.1AX) that dynamically aggregates multiple physical network links into a single logical channel; Active-Passive Clustering pairs with Redundancy configuration where a secondary standby device monitors the primary device and assumes processing only upon primary node failure.
HSRP is a Cisco-proprietary default gateway protocol, VRRP is an open-standard default gateway protocol, LACP provides Layer 2 multi-link aggregation under IEEE standards, and Active-Passive clustering designates a standby node for failover capability.

Step-by-Step Solution

1
Differentiate between First Hop Redundancy Protocols based on vendor ownership.
Match HSRP to Cisco-proprietary gateway redundancy and VRRP to open-standard gateway redundancy.
HSRP was created by Cisco, while VRRP was standardized by the IETF for vendor-agnostic deployments.
2
Identify link aggregation protocols operating at Layer 2.
Match LACP to the IEEE 802.3ad/802.1AX standard for combining physical switch ports.
LACP bundles physical interfaces into a unified logical link to increase bandwidth and provide link failover.
3
Identify system failover operational modes.
Match Active-Passive Clustering to standby failover behavior.
In active-passive setups, the passive node remains idle regarding traffic processing until a failover event occurs.
