HSRP has been configured between two Company devices. Which of the following describe
reasons for deploying HSRP? (Select all that apply)
A.
HSRP provides redundancy and fault tolerance
B.
HSRP allows one router to automatically assume the function of the second router if the
second router fails
C.
HSRP allows one router to automatically assume the function of the second router if the
second router starts
D.
HSRP provides redundancy and load balancing
Explanation:
One way to achieve near-100 percent network uptime is to use HSRP, which provides
network redundancy for IP networks, ensuring that user traffic immediately and transparently
recovers from first hop failures in network edge devices or access circuits.
By sharing an IP address and a MAC (Layer 2) address, two or more routers can act as a
single “virtual” router. The members of the virtual router group continually exchange status
messages. This way, one router can assume the routing responsibility of another, should it
go out of commission for either planned or unplanned reasons. Hosts continue to forward IP
packets to a consistent IP and MAC address, and the changeover of devices doing the
routing is transparent.
Through the use of multiple HSRP standby groups, traffic can be load balanced between the
HSRP routers. For example, users on one VLAN could use one router as the primary HSRP
router, and users on another VLAN can use the other HSRP router as the primary.
