  • A: Ctrl-z
  • B: Ctrl-c
  • C: Esc
  • D: Shift-Page Down



Question 2
Which of the following best describes a repeater?

  • A: A passive device simply used to connect two or more cables. Does not generate or amplify any signals.
  • B: A device that receives and retransmits a signal out its ports, but does not do any Layer 2 analysis of the data.
  • C: A device that receives a signal and based on the Layer 2 destination address, makes a decision on which ports the signal should be retransmitted.
  • D: A device that receives a signal and based on the Layer 3 destination address, makes a decision on which ports the signal should be retransmitted.



Question 3
How do protocols such as ATM and Frame-Relay support differentiating multiple customers or traffic types on the same physical wire?

  • A: ATM and Frame-Relay are circuit switched protocols and use Virtual Circuits to create logical separation of traffic.
  • B: ATM and Frame-Relay are point-to-point protocols and do not support different customers or traffic type on the same physical wire.
  • C: ATM and Frame-Relay are circuit switched protocols and use VLAN's to create logical separation of traffic.
  • D: ATM and Frame-Relay are circuit switched protocols and use IP Header information to create logical separation of traffic.



Question 4
Which of the following is a feature of Layer 3?

  • A: Provides an universal addressing scheme
  • B: Ensures data is delivered across the Layer 2 network.
  • C: Provides reliable data transfers.
  • D: Provides a physical interface to the network.



Question 5
The 201.148.26.0/24 network is subnetted using a /26 mask. How many subnets and host addresses will you obtain with this mask?

  • A: 4 subnets, 64 hosts
  • B: 64 subnets, 4 hosts
  • C: 4 subnets, 62 hosts
  • D: 64 subnets, 2 hosts
  • E: 6 subnets, 30 hosts



Question 6

  • A: Details of the configuration settings of each router on the network.
  • B: A list of other DHCP clients.
  • C: IP addresses and their lease times.
  • D: Server time information



Question 7
Choose two true statements that characterize Link State Routing

  • A: Routers send a copy of their routing table to their neighbors periodically.
  • B: Routers flood link information throughout the entire area.
  • C: Network converges quickly (within several seconds) after a topology change.
  • D: Routers do not have precise knowledge of the entire network topology.



Question 8
Which statement accurately explains the purpose of the TCP protocol and what it provides?

  • A: The primary purpose of TCP is to provide reliable communications between application services.
  • B: The primary purpose of TCP is to provide unreliable communications between application services
  • C: The primary purpose of TCP is to provide IP routing between application services.
  • D: The primary purpose of TCP is to define the correct format for the application layer such as JPEG or HTML.



Question 9
Which of the following is the best description of well known ports?

  • A: Well known ports apply to routers only and are used for communication and control traffic. Well known port numbers are assigned by IANA and can have any value.
  • B: Well known ports are used by TCP and UDP. Well known port numbers range from 1024 to 65535 and are assigned by IANA.
  • C: Well known port numbers are used by both TCP and UDP. Well known port numbers range from 1 to 1023 and are assigned by IANA.
  • D: Well known ports numbers are used by TCP only. Well known port numbers are assigned by IANA and can have any value.
