Hot Standby Routing Protocol (HSRP)
11.
A, C, D, E, F. HSRP allows most protocols including IP, AppleTalk,
Banyan Vines, Novell IPX, DECnet, and XNS.
12.
D. An HSRP router will enter the listen state after the virtual IP
address is known.
13.
A. You can have only one router answering for the virtual IP address
at a time.
14.
B. The
command
show ip arp
will display the contents of the ARP
cache. The entries are valid for four hours by default.
15.
D. If you set the default gateway on a Windows device to the same
address as the workstation's IP address, the workstation will arp for
every device as if it were local. A router running the Proxy ARP pro-
tocol will forward those requests if necessary.
16.
A, C, D, E. Proxy ARP, dynamic routing protocols running on hosts
(RIP, for example), IRDP, and HSRP are used to provide fault toler-
ance in routed networks.
17.
B. Routers send IRDP multicasts to IRDP hosts every 7 to 10 min-
utes. The hosts will hold this information up to 30 minutes.
18.
C. The
show standby
command will display the virtual IP address,
the virtual MAC address, and the IP address of the active and standby
routers.
19.
A. HSRP was developed by Cisco and only works with the
Cisco IOS.
20.
C. The
show standby
command will display the virtual IP address,
the virtual MAC address, and the IP address of the active and standby
routers.
