Network ImplementationQuestion 35 of 100
A network requires automatic failover of the default gateway between two routers. Which category of protocol provides this?
a.Link aggregation protocol
b.Spanning tree protocol
c.Address resolution protocol
d.First hop redundancy protocol
Explanation
First hop redundancy protocols such as HSRP, VRRP, and GLBP provide a virtual gateway IP shared by multiple routers for automatic failover. If the active router fails, a standby takes over transparently to hosts. This eliminates the gateway as a single point of failure.
