Refer to the exhibit. Which three statements identify the type of cabling that would be used in the segments that are shown? (Choose three.) 
  • Segment 1 uses backbone cabling. 
  • Segment 1 uses a patch cable. 
  • Segment 3 uses patch cabling. 
  • Segment 3 uses vertical cabling. 
  • Segment 3 uses horizontal cabling. 
  • Segment 4 uses vertical cabling.
Refer to the exhibit. How many subnets are required to support the network that is shown? 
  • 5
6. What does the term "attenuation" mean in data communication? 
  • loss of signal strength as distance increases 
  • time for a signal to reach its destination 
  • leakage of signals from one cable pair to another 
  • strengthening of a signal by a networking device
7. Which option identifies the primary interface which would be used for initial configuration of a Cisco router? 
  • AUX interface 
  • Ethernet interface 
  • serial interface 
  • console interface
Refer to the exhibit. A student working in the lab selects a cable that is wired as shown. Which connection types can successfully be made with this cable? (Choose two.) 
  • connecting a PC to a router's console port 
  • connecting two routers together via their fast ethernet ports 
  • connecting two switches together at gigabit speeds

9. What type of network cable is used between a terminal and a console port? 
  • cross-over 
  • straight-through 
  • rollover 
  • patch cable
Refer to the exhibit. Based on the IP configuration shown, what would be the result of Host A and Host B attempting to communicate outside the network segment? 
  • both host A and B would be successful 
  • host A would be successful, host B would fail 
  • host B would be successful, host A would fail 
  • both Host A and B would fail
11. How many host addresses may be assigned on each subnetwork when using the network address with a subnet mask of 
  • 30 
  • 256 
  • 2046 
  • 2048 
  • 4094 
  • 4096
12. A network administrator is required to use media in the network that can run up to 100 meters in cable length without using repeaters. The chosen media must be inexpensive and easily installed. The installation will be in a pre-existing building with limited cabling space. Which type of media would best meet these requirements? 
  • STP 
  • UTP 
  • coaxial 
  • single-mode fiber 
  • multimode fiber
Refer to the exhibit. A network technician has been allocated the private IP address range for use in the network that is shown in the exhibit. Which subnet mask would be used to meet the host requirements for segment A of this internetwork? 
14. Refer to the exhibit. What destination IP address will PC1 place in the header for a packet destined for PC2? 
15. Which device is used to create or divide broadcast domains? 
  • hub 
  • switch 
  • bridge 
  • router 
  • repeater
Refer to the exhibit. Which three statements are true about the exhibited topology? (Choose three.) 
  • Hosts B and C are in the same subnet. 
  • Five broadcast domains are present.
  • Host B is using a crossover cable to connect to the router. 
  • Four broadcast domains are present. 
  • Five networks are shown. 
  • Host B is using a rollover cable to connect to the router.
17. Which three types of connectors are commonly associated with Cisco's V.35 serial cables? (Choose three.) 
  • RJ 11 
  • DB 60 
  • Winchester 15 pin 
  • DB 9 
  • smart serial 
  • RJ 45

  • crossover cable 
  • straight through cable 
  • rollover cable 
  • V.35 cable
19. Which three statements are true about the role of routers in the network? (Choose three.) 
  • They propagate broadcasts. 
  • They enlarge collision domains. 
  • They segment broadcast domains. 
  • They interconnect different network technologies. 
  • Each router interface requires a separate network or subnet. 
  • They maintain a common frame format between LAN and WAN interfaces.
20. What are two common methods for setting a UTP Ethernet port to MDI or MDIX operation? (Choose two.) 
  • cable color code association
