Which technology can provide high availability in a network environment?

The Virtual Router Redundancy Protocol (VRRP) is specifically designed to enhance the availability and reliability of network routing. It accomplishes high availability by allowing multiple routers to work together to present the illusion of a single virtual router to the end devices on the network. This is achieved through a designated master router that forwards traffic while backup routers stand by to take over in the event of a master router failure. This redundancy ensures that if one router fails, another can immediately take its place without causing disruption in service, thereby maintaining continuous network operation.

In contrast, Spanning Tree Protocol (STP) is predominantly used for preventing loops in Ethernet networks. While it can contribute indirectly to network reliability by ensuring that there is no broadcast storm caused by loops, it does not directly manage redundancy or router failover in the same manner that VRRP does.

Link Aggregation Control Protocol (LACP) is used for combining multiple network connections to increase throughput and provide redundancy for individual links. While LACP improves link reliability by distributing traffic across multiple physical links, it does not handle router failover situations like VRRP.

Open Shortest Path First (OSPF) is a routing protocol that contributes to the efficiency and speed of route selection in a network, but it does
