  1. What information is contained in the header of Layer 3 to help data delivery? destination host logical address
  2. Refer to the exhibit. Which logical topology describes the exhibited network? point-to-point
  3. Which of the following are the address ranges of the private IP addresses? (Choose three.) 10.0.0.0 to 10.255.255.255 ; 172.16.0.0 to 172.31.255.255 ; 192.168.0.0 to 192.168.255.255
  4. Refer to the exhibit. A host is using NAT to connect to the Internet. Which three IP addresses enable this connection? (Choose three.) 10.1.1.37 ; 10.1.1.39 ; 10.1.1.60
  5. 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.
  6. 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.
  7. 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, 5, 6
  8. Refer to the exhibit. Each media link is labeled. What type of cable should be used to connect the different devices? Connection 1 - straight-through cable Connection 2 - straight-through cable Connection 3 - straight-through cable
  9. Which range of port numbers is assigned dynamically to client applications when initiating a connection to the server? 1024 to 49151
  10. Refer to the exhibit. Which set of devices contains only intermediary devices? A,B,D,G
  11. Refer to the exhibit. The network administrator remotely accesses the CLI of RouterB from PC1 using a secure connection. Which statement is true about this connection? The connection is made through a VTY session on the router.
  12. Refer to the exhibit. Communication for hosts X and Y is restricted to the local network. What is the reason for this?
  13. In a Cisco IOS device, where is the startup-configuration file stored? NVRAM
  14. Which three statements are true about network layer addressing? (Choose three.) It uniquely identifies each host ; It supports data communications between networks ; It prevents broadcasts.
  15. As network administrator, what is the subnet mask that allows 510 hosts given the IP address 172.30.0.0? 255.255.254.0
  16. Refer to the exhibit. The router of the company failed and was replaced. After the replacement, hosts C and D in the Education office are able to ping each other, but they are unable to access the hosts in the Accounts office. What is the likely cause of the problem? The IP address at the fa0/0 interface of the router is incorrectly configured.
  17. Refer to the exhibit. RouterB is configured properly. The Ethernet interface Fa0/0 of RouterA is configured with the use of the commands that are shown. However, a ping from the Fa0/0 interface of RouterA to the Fa0/0 interface of RouterB is unsuccessful. What action should be taken on RouterA to solve this problem?
  18. Which three statements characterize the transport layer protocols? (Choose three.) TCP and UDP port numbers are used by application layer protocols ; UDP uses windowing and acknowledgments for reliable transfer of data; TCP uses windowing and sequencing to provide reliable transfer of data.
  19. What are three characteristics of CSMA/CD? (Choose three.) Devices listen to the media and transmit data only when they cannot detect another signal on the media; All devices on the media can hear all communications; When a collision occurs, all devices stop transmitting for a randomly generated period of time
  20. Which OSI layer uses the header information to reassemble the data segments into streams? transport layer
  21. Due to a security violation, the router passwords must be changed. What information can be learned from the following configuration entries? (Choose two.)
  22. Refer to the exhibit. Host B was powered off. What change will occur in the MAC table of the switch?
  23. 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
  24. Refer to the exhibit. A technician is working on a network problem that requires verification of the router LAN interface. What address should be pinged from this host to confirm that the router interface is operational? 192.168.254.1
  25. Refer to the exhibit. Host A is transmitting data to host B. Which address combination will be used as the data leaves the Router1 Fa0/1 interface?
