What does HSRP stand for in networking?

Hot Standby Router Protocol
High Speed Router Protocol
Host Standby Redundancy Protocol
High Standard Routing Protocol

The correct answer is: Hot Standby Router Protocol

HSRP stands for Hot Standby Router Protocol. It is a Cisco proprietary redundancy protocol that is used to ensure high availability of network routers. HSRP allows multiple routers to work together to present the appearance of a single virtual router to the devices on the local network. This is particularly useful to prevent a single point of failure and ensure continuous network availability. When one router in the HSRP group becomes the active router, the other routers participate as standby routers, ready to take over should the active router fail. This seamless failover process enhances network resilience and minimizes downtime. Understanding how HSRP operates is crucial for network design and implementation, especially in environments where continuous connectivity is critical. The other options do not accurately describe HSRP or its function in networking.
