1. Refer to the exhibit. Host B attempts to establish a TCP/IP session with host C. During this attempt, a frame was captured at the FastEthernet interface fa0/1 of the San Francisco router. The packet inside the captured frame has the source IP address 10.10.1.2, and the destination IP address is 10.31.1.20. What is the destination MAC address of the frame at the time of capture?
2. What are three characteristics of CSMA/CD? (Choose three.)
• It monitors the media for presence of a data signal.
• After detecting a collision, hosts can resume transmission after a random timer has expired.
• A jam signal is used to ensure that all hosts are aware that a collision has occurred.
3. Refer 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?
• router interface fa0/0
4. Refer 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
5. Refer to the exhibit. Communication between hosts X and Y is restricted to the local network. What is the reason for this?
• Host X and host Y belong to different networks.
6. What is the result of using the clock rate 56000 command at the serial interface of the router?
• The interface is configured as a DCE device.
7. Which three addresses belong to the category of public IP addresses? (Choose three.)
8. Which three statements are true about transport layer protocols? (Choose three.)
• TCP and UDP manage communication between multiple applications.
• TCP acknowledges received data.
• UDP uses windowing and sequencing to provide reliable transfer of data.
9. Refer to the exhibit. Which logical topology describes the exhibited network?
10. Which statement is true about the running configuration file in a Cisco IOS device?
• It affects the operation of the device immediately when modified.
11. Refer to the exhibit. Host C is able to ping 127.0.0.1 successfully, but is unable to communicate with hosts A and B in the organization. What is the likely cause of the problem?
• The subnet mask on host C is improperly configured.
12. A 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 a connectionless protocol only for multiple simultaneous transmissions.
13. 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?
14. 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 2
• Segment 5
• Segment 6
15. Refer to the exhibit. Which two facts can be determined about the topology? (Choose two.)
• Two logical address ranges are required.
• A single broadcast domain is present.
16. Refer to the exhibit. Which three statements are true about the IP configuration that is displayed? (Choose three.)
• The assigned address is a private address.
• The prefix of the computer address is /26.
17. Which password restricts Telnet access to the router?
18. Refer to the exhibit. To create the initial configuration, a network technician connected host A to the router using the connection that is shown. Which statement is true about this connection?
• It provides out-of-band console access.
