Part 1 Media and Topologies Quiz

  • Question #1
  • What multiport device connects network segments and allows full bandwidth on all ports?

  • A. Repeater
  • B. Hub
  • C. Switch
  • D. MAU


  • Answer: C

  • Explanation:
  • A switch allows full bandwidth on all ports.
  • A repeater only repeats the signals.
  • A hub splits the available bandwidth equally among the active ports on the hub.
  • A MAU is a hub used in token ring network.

  • Question #2
  • Which access method does Gigabit Ethernet use?

  • A. ATM
  • B. CSMA/CD
  • C. Frame Relay
  • D. Token passing


  • Answer: B

  • Explanation:
  • Ethernet, including Gigabit Ethernet, use the CSMA/CD(Carrier Sense Multiple Access with Collision Detection) access method.

  • Question #3
  • Which medium connects a Small Office-Home Office (SOHO) computer to an external DSL modem?

  • A. RG-58 coaxial
  • B. Category 5 UTP
  • C. RS-232 serial cable
  • D. Single-Mode Fiber Optic


  • Answer: B

  • Explanation:
  • The computer is connected to the DSL modem with a standard Category 5 UTP cable.

  • Question #4
  • Which three devices provide a path between a node on one LAN and a node on another LAN?

  • A. hub
  • B. router
  • C. bridge
  • D. switch
  • E. managed hub


  • Answer: B,C and D

  • Explanation:
  • A router routes traffic between different networks.
  • A bridge connects two networks segment.
  • A switch works like a hub, but it reduces broadcasts and provides better bandwidth.
  • An unmanaged hub is a black box that has a prescribed job to do and does it according to its design. In general, there is no way to alter its operations through a network interface.
  • A managed hub has at least alerting capabilities with some type of SNMP or HTTP mechanism that might allow an administrator to change the operation of the hub in some way for instance, to shut down a port connecting to a cetain system or device.

  • Question #5
  • Which two devices typically provide hardware data loopback capabilities?(Choose two)

  • A. bridges
  • B. modems
  • C. CSU/DSUs
  • D. Ethernet hubs
  • E. Wireless access points


  • Answer: C and D

  • Explanation:
  • CSU/DSU provide hardware data loopback testing capabilities. Ethernet hubs also typically provide loopback capabilities.

  • Question #6
  • Which device connects multiple computers to create a single logical network segment?

  • A. hub
  • B. nic
  • C. router
  • D. bridge


  • Answer: A

  • Explanation: A hub connects multiple computers to create a single logical network segment.

  • Question #7
  • Which medium connects a client to a 100Base-T switch?

  • A. coaxial
  • B. fiber optic
  • C. Category 3 UTP
  • D. Category 5 UTP


  • Answer: D

  • Which cable type is most susceptible to cross-talk?

  • A. UTP
  • B. STP
  • C. coaxial
  • D. fiber optic


  • Answer: A

  • Explanation:
  • Unshielded twisted pair cables are most cross-talk susceptible

  • Question #9
  • Which media connector connects a client to a 100Base-FX switch?

  • A. coaxial
  • B. fiber optic
  • C. Category 3 UTP
  • D. Category 5 UTP


  • Answer: B
