Pregunta 2
Pregunta
Which three statements about HSRP operation are true? (Choose three)
Respuesta
-

work, as defined by one of the FHRP protocols. Which of the following does
the FHRP make happen?
Respuesta
-
Packets sent off-subnet, host B encapulates the packets in Ethernet frames, destined to VMAC 2, so that they arrive at R2
-

-
Prevents the overlap on a single router.
-
Sends messages in the network to test connectivity.

-
Show standby brief
-
Show glbp
-
Standby version

address.
Respuesta
-
Show standby
-
Show glbp
-
Show standby glbp
-
Show glbp brief
