TESTOUT EXAM #1 QUESTIONS AND
ANSWERS
Routing data between computers on a network requires several mappings between
different addresses. Which of the following statements is true? - Answer- Routers uses
ARP to resolve known IP addresses into MAC addresses by broadcasting requests to
the network.
Used to get the IP address of a host from a known MAC address - Answer- RARP &
BOOTP
Used to transfer files - Answer- TFTP & FTP
Used to identify routes through an internetwork - Answer- OSPF & RIP
The serial 0/1/0 interface on Router A is connected to the Serial 0/0/1 interface on
Router B. The link between the routers uses subnet address 172.99.5.112 with a mask
of 255.255.240
Router A is unable to communicate with Router B. You review the interface status on
Router A and see the following information:
RouterA# sh int s0/1/0
Serial0/1/0 is up, line protocol is up
Hardware is GT96K Serial
Internet address is 172.99.5.129/28 MTU 1500 bytes, BW 1544 Kbit, DLY 2000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation HDLC, loopback not set
Keepalive set (10 sec)
--additional output omitted
What is the problem? - Answer- The IP address assigned to the interface is not on the
172.99.5.112
Which of the following best describes how a switch functions? - Answer- -It filters the
network traffic based on hardware addresses
-It connects multiple network segments and forwards packets to the appropriate
Which of the following are characteristics of a switch? - Answer- -The collision domain
on a switch is all devices connected to a single switch port
