Match each high availability and redundancy mechanism to its corresponding operational characteristics within an enterprise network design.
- Link Aggregation Control Protocol (LACP)Bundles multiple physical Ethernet interfaces into a single logical channel to increase bandwidth and provide link fault tolerance.
- Virtual Router Redundancy Protocol (VRRP)Presents a single Virtual IP (VIP) address to client workstations to ensure uninterrupted default gateway availability.
- Equal-Cost Multi-Path (ECMP)Distributes Layer 3 traffic dynamically across multiple parallel paths having identical routing metric costs.
- Stateful Firewall Pair SynchronizationReplicates connection tracking tables across active and standby appliances to preserve active sessions during failover.
Answer
Link Aggregation Control Protocol (LACP) matches bundling physical Ethernet interfaces into a single logical channel. Virtual Router Redundancy Protocol (VRRP) matches presenting a single Virtual IP address for default gateway redundancy. Equal-Cost Multi-Path (ECMP) matches distributing Layer 3 traffic across multiple parallel paths of identical cost. Stateful Firewall Pair Synchronization matches replicating connection tracking tables across appliances.
High availability designs utilize specialized protocols at different layers: LACP bundles physical links for bandwidth and link failover, VRRP manages Virtual IPs for default gateway redundancy, ECMP balances routing traffic over equal-cost paths, and stateful synchronization maintains active session tables across security appliances during a failover event.
