What does HSRP stand for in network protocols?

1. Hot Standby Router Protocol

2. High Speed Routing Protocol

3. Hierarchical Standby Routing Protocol

4. Hot Standby Redundancy Protocol

The correct answer is: Hot Standby Router Protocol

HSRP stands for Hot Standby Router Protocol, which is a networking protocol that provides high availability for IP networks. Specifically, it allows for the setting up of a virtual router that provides redundancy in a LAN environment. When primary routers in a network fail, HSRP enables a standby router to take over automatically without causing disruption to the services or requiring manual intervention. This protocol operates by designating one router as the active router and another as the standby router. In the event that the active router fails, the standby router can take over the traffic forwarding responsibilities seamlessly, which is crucial for maintaining continuous network service. HSRP is most commonly used in environments where uptime is critical, such as data centers and enterprise networks. Choosing this option reflects an understanding of how network protocols enhance reliability and redundancy in networking infrastructure.
