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?
• 0060.7320.D632

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.)
• 196.1.105.6
• 132.11.9.99
• 46.1.1.97
 

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?
• point-to-point

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?
• 192.168.0.250

 

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?
• enable

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.

19. Which device should be used for routing a packet to a remote network?
• router

 

20. Refer to the exhibit. The serial interface of the router was configured with the use of the commands that are shown. The router cannot ping the router that is directly connected to interface serial 0/0/0. What should the network technician do to solve this problem?
• Configure an IP address on interface serial 0/0/0.

21. Refer to the exhibit. In a network, host A is sending data segments to host B. The flow control of the segments that are being exchanged is displayed. Which two statements are true about this communication? (Choose two.)
• The initial window size is determined via the two-way handshake.
• Acknowledgment number 3001 indicates that host A will send the next segment with sequence number 3001.
