Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A group of IP addresses that have the same value in the first part of the IP addresses - for the purpose of allowing routing to identify the group by the inital part of the addresses. IP addresses in the same subnet typically sit on the same network






2. A network model defined by the IETF that has been implemented on most computers and network device in the world.






3. A term that describes IPv4 packets sent to all hosts in a particular network. In a directed broadcast - a single copy of the packet is routed to the specified network - where it is broadcast to all hosts on that network






4. A routing feature in which frames in an interface output queue are prioritized based on various characteristics such as packet size and interface type.






5. A service or a program to look up information in the DNS






6. A notification sent from one network device to another to confirm that some event has occured.






7. Represents the 0 in the binary number. In an IP subnet mask - the lower-order bits represent the host portion. Sometimes called the host portion of bits.






8. In networking - this term is used in several ways. With ethernet hub and switch hardware - port is simply another name for interface - which is a physical connector in the swithc into whic a cable can be connected. With TCP and UDP - a port is a soft






9. The header defined by the IP. Used to create IP packets by encapsulating data supplied by higher-layer protocol (such as TCP) behind an IP header.






10. A process used by a switch or bridge to forward broadcasts and unknown destination unicasts. The bridge/switch forwards these frames out all ports except the port on which the frame was received.






11. A drag-and-drop network simulator developed by Cisco to design - configure and troubleshoot network equipment within a controlled - simulated program environment.






12. The arrangement of the nodes in a network and the physical connections between them. This is the representation of how the media is used to connect the devices.






13. Defines the commands - headers and processes by which web server and web browsers transfer files.






14. In the telnet application - commands are always introduced by a character with the decimal code 255 - known as the Interpret as Command character.






15. A common term for 10base2 ethernet - referring to the fact that 10base2 cabling is thinner than coaxial cabling used for 10base5






16. Also known as boolean algebra. These consist of the AND OR and IF operations






17. A type of hash function that is used to produce a small - fixed size checksum of a block of data - such as a packet or a computer file. A CRC is computed and appended before transmission or storage - and verified afterward by the recipient to confirm






18. A layer 4 protocl of TCP/IP model - TCP lets applications guarantee delivery of data across a network.






19. An international standards body that defines many networking standards. Also - the standards body that created the OSI model.






20. An application level network protocl mainly applied to shared access to files - printers - serial ports - and miscellaneous communications between nodes on a network.






21. The MAC address that is permanently assigned to a LAN interface or NIC. It is called burned-in because the address is burned into a chip on the card - and the address cannot be changed. Also called universally administered address.






22. Line code in which 1s are represented by one significant condition and 0s are represented by another.






23. A rectangular cabling connector with eight pins - often used with ethernet cables.






24. The time required to send a single bit over some transmission medium. The time can be calculated at 1/speed - where speed is the number of bits per second sent over the medium






25. A plan - design or program of action to be followed. Sometimes an addressing plan is called an addressing SCHEME.






26. Refers to whether the performance of a device - attached to a particular type of LAN - can be accurately predicted. Token Ring LANS are deterministic - but ethernet LANS are non deterministic.






27. A common term for 10base5 ethernet - referring to the fact that 10base5 cabling is thicker than the coaxial cabling used for 10base2.






28. A process used to verify the identity of a person or process






29. A unicast IP address that is considered to have three parts: a network part - a subnet part - and a host part. The term classful refers to the fact that classful network rules are first applied to the address - and then the rest of the address can be






30. 1. a collision domain that is a section of a LAN that is bound by bridges - routers or switches. 2. In a LAN using a bus topology - a segment is a continuous electrical circuit that is often connected to other such segments with repeaters. 3. When us






31. The structure and order of words in a computer language






32. A device that connects to a local digital telephone loop for a WAN circuit to a serial interface on a network device - typically connecting to a router. The CSU/DSU performs physical Layer 1 signaling on WAN circuits






33. The glass fibers inside certain cables over which light is transmitted to encode 0 and 1






34. MDIX is an alternative operation of ethernet ports on a hub. In this mode - the mapping of the wire pairs used in the hub port is in a crossover configuration. This allows you to use a straight-through cable to interconnect the hub to another hub.






35. A written specification that defines what tasks a service or device should perform. Each protocol defines messages - often in the form of headers - plus the rules and processes by which these messages are used to achieve some stated purpose.






36. The bit position in a binary number having the greatest value. The most significant bit is sometime referred to as the leftmost bit.






37. A numbering system characterized by 1 and 0






38. A convention for writing IP addresses with four decimal numbers - ranging from 0 to 255 - with each octet representing 8 bits of the 32 bit IP address. The term originates from the fact that each of the four decimal numbers is separated by a period.






39. Ethernet that transmits data at 1 -000 -000 -000 one billion bits per second.






40. A group of 8 binary bits. It is similar to - but not the same as - a byte. One Application in computer network is to use octets to divide IPv4 addresses into four components






41. The first half of a MAC address. Manufactures must ensure that the value of the OUI has been registered with the IEEE. This value identifies the manufacturer of any Ethernet NIC or interface.






42. A member of a multicast group. Every multicast client in each group has the same IP address. Multicast addresses begin with 224... and end with 239...






43. A network scanning technique used to identify which host IP addresses are operational.






44. The layer 3 address to which the data is going.






45. The physical interface transceivers. It deals with Layer 1 (the physical layer - hence the PHY) of ethernet.






46. A communication path over a medium used to transport information from a sender to a receiver. Multiple channels can be multiplexed over a single cable






47. The IPv4 multicast addresses 224.0.0.0 to 224.0.0.255. These addresses are to be used for multicast groups on a local network. Packets to these destinations are always transmitted with a TTTL value of 1






48. A device on a network that serves as an access point to other networks. A default gateway is used by a host to forward IP packets that have destination addresses outside the local subnet. A router interface typically is used as the default gateway. W
