This preview shows page 7 - 12 out of 18 pages.

20A host is transmitting a video over the network. How does the transport layer allow this host to use multiple applications to transmit other data at the same time as the video transmission? It uses error control mechanisms. It uses a connectionless protocol only for multiple simultaneous transmissions. It uses multiple Layer 2 source addresses. It uses multiple port numbers.
21What is the result of using the clock rate 56000command at the serial interface of the router?
22
Refer to the exhibit. PC1 is unable to access PC2. To troubleshoot this problem, the technician needs to confirm that the next hop interface is operational. Which default gateway address should the technician ping from PC1 to confirm this?
23Refer to the exhibit. The PC, the routing table of which is displayed, is configured correctly. To which network device or interface does the IP address 192.168.1.254 belong?
24
Refer to the exhibit. A technician has connected the PC to the switch using a Category 6 UTP cable. Which two statements are true about this connection? (Choose two.) The cable that is used is an Ethernet crossover cable. The transmit pin of the cable is terminated to the receive pin. The maximum distance between the switch and the PC can be 100 m. The maximum supported bandwidth is 1000 Mb/s. The Category 6 cable simulates a point-to-point WAN link and is unusable for this type of connection.
25Refer to the exhibit. Host X is unable to communicate with host Y. Which command can be run at host X to determine which intermediary device is responsible for this failure?
26
Refer to the exhibit. Cable 1 and Cable 2 are wired for specific physical layer requirements. Which three segments use Cable 2? (Choose three.)
Segment 6 27Refer to the exhibit. Host A wants to access the Internet. Which combination of a Layer 2 address and a Layer 3 address will enable this access from host A?
Destination MAC: 0030.8517.44C4 Default gateway: 172.16.1.1 Destination MAC: 0030.8517.44C4 Default gateway: 209.165.202.130
