Match each enterprise high-availability mechanism or protocol on the left with its correct operational description on the right.
- VRRP (Virtual Router Redundancy Protocol)An open-standard Layer 3 protocol that allows multiple routers to share a virtual IP address for default gateway failover.
- LACP (Link Aggregation Control Protocol)A Layer 2 standard (IEEE 802.1AX) that dynamically bundles multiple physical network links into a single logical trunk.
- CARP (Common Address Redundancy Protocol)A redundancy protocol designed to allow multiple security appliances or hosts to share IP addresses on a network segment, often paired with state synchronization.
- MPIO (Multipath I/O)A storage networking feature that creates redundant physical paths between a host server and SAN storage arrays for fault tolerance and load balancing.
Cevap
VRRP pairs with the open-standard Layer 3 virtual IP default gateway failover protocol; LACP pairs with IEEE 802.1AX Layer 2 physical link aggregation; CARP pairs with shared IP host/firewall cluster redundancy; MPIO pairs with storage area network redundant physical pathing.
Each mechanism matches its exact function: VRRP provides standard open Layer 3 virtual default gateway redundancy; LACP aggregates Layer 2 Ethernet links into a logical interface; CARP handles shared IP addresses for host and firewall clusters; and MPIO provides redundant physical connectivity to storage array targets.
