Zorluk: KolayHigh Availability and Redundancy Concepts

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.

Adım Adım Çözüm

1
Differentiate First-Hop Redundancy Protocols (FHRP) by vendor standards.
Identify HSRP as Cisco-proprietary and VRRP as the open-standard alternative for gateway fault tolerance.
Both HSRP and VRRP create virtual gateways, but their standard designations differ.
2
Identify link-level aggregation protocols.
Associate LACP with IEEE 802.3ad port channeling for bandwidth aggregation and link redundancy.
LACP aggregates switch interfaces at Layer 2 rather than routing at Layer 3.
3
Identify system failover deployment models.
Associate Active-Passive Clustering with primary node processing and standby secondary node takeover.
Active-Passive design ensures dedicated hardware failover without load sharing during normal operations.
