TESTOUT EXAM #1 QUESTIONS WITH COMPLETE SOLUTIONS.

Routing data between computers on a network requires several mappings between different addresses. Which of the following statements is true? - 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 - RARP & BOOTP Used to transfer files - TFTP & FTP Used to identify routes through an internetwork - 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? - 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? - -It filters the network traffic based on hardware addresses -It connects multiple network segments and forwards packets to the appropriateWhich of the following are characteristics of a switch? - -The collision domain on a switch is all devices connected to a single switch port -A switch reads the MAC address in a frame and makes forwarding decisions based on that address Wrk1 is connected to port Fa0/16 on your Cisco 2960 switch. The user complains that she can't access the network server. You verify that a cable is connected to the Fa0/16 port on that switch. You press the Mode button select Stat, Duplex, and Speed. Each time the port light remains off. Which command would most likely correct the problem? - no shutdown You have been put in charge of connecting two company networks that were previously separated. You need to connect a 100BaseTx Ethernet network with an older token ring network. Most traffic will be localized within each network, with only a little traffic crossing between networks. Both networks are using the TCP/IP protocol suite. Which connectivity device would be the best choice in this situation? - Router Which of the following are general advantages of using routers on your network? (Select three.) - -Routers provide multiple links between devices to support load balancing -Routers support multiple routing protocols for better flexibility -Routers provide more features, such as flow control, error detection, and congestion control, than switches or bridges Used to send email messages between mail servers - SMTP Used to send messages to groups of users - IGMP
