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. An IPV4 addressing scheme that uses a subnet mask that does not follow classful addressing limitations. It provides increased flexibility when dividing ranges of IP addresses into separate networks. Classless addressing is considered the best in curr






2. A part of a computer network that every device communicates with using the same physical medium. Network segments are extended by hubs or repeaters.






3. A MAC address that can be configured on a device. The LAA can be used in place of the BIA . This means that you can replace a NIC or use a substitute device without changing the address used by the network to access the station.






4. A group that receives a multicast transmission. The members of a multicast group have the same mulitcast IP addressing to receive the same transmission.






5. A popular certification method for fiber systems. The OTDR injects light into the fiber and then graphically displays the results of the detected reflected light. The OTDR measures the elapsed transit time of reflected light to calculate the distance






6. The optical or electrical impulse on a physical medium for purposes of communication.






7. In networking - a general term referring to any energy signal on a transmission medium that is not part of the signal used to transmit data over that medium.






8. Additional data that is provided with a command to provide information used by the execution of the command. IOS command arguments are entered at the CLI after the command






9. A dotted decimal number defined by the IPv4 protocol to represent a network or subnet. It represents the network that hosts reside in. Also called a network number or network ID.






10. Translation RFC 1918 addresses to public domain addresses. Because RFC 1918 addresses are not routerd on the Internet - hosts accessing the Internet must use public domain addresses.






11. The process of obscuring information to make it unreadable without special knowledge - somtimes referred to as scrambling. The process takes the data to be encrypted and applies a mathematical formula to it along with a secret number. The resulting v






12. A process by which an end device - after it receives data over some transmission medium - examines the headers and trailers at each successive higher layer - eventually handing the data to the correct application. Sometimes called de-encapsulation.






13. 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.






14. In IP subnetting - this refers to the portion of a set of IP addresses whose value must be identical for the addresses to be in the same subnet.






15. Communication where the sender and receiver must prearrange for communications to occur; otherwise - the communication fails.






16. 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.






17. The IPv4 address block 192.0.2.0 to 192.0.2.255 that is set aside for teaching and learning purposes. These addresses can be used in documentation and network examples.






18. On a switch - a table that lists all known MAC addresses - and the bridges/switch port out which the bridge/switch should forward frames sent to each MAC address.






19. A collection of data that establishes a reference for network performance and behavior over a period of time. This reference data is used in the future to assess the health and relative growth of network utilization.






20. As filed in the TCP header that is set in a sent segment - signifies the maximum amount of unacknowledged data the host is willing to receive before the other sending host must wait for an acknowledgment.






21. An addressing scheme in which a network is partitioned into sections - with the section identifier forming one part of each destination's address and the destination identifier forming another






22. A unit of measurement of the number of times 1000 bits can be transmitted in 1 second. 1 kbps = 1000bps






23. A host or node that participates in some form of a group. For example - p2p technology defines a group of peers that participate jointly in the same activity - each one having a server and client component.






24. A network with a geographic size between a LAN and a WAN. Typically used by service providers to create a highspeed network in a major metropolitan area where many customers might want high speed services between large sites around a city.






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






26. A system of network design characterized by one or more major components that are required to maintain operation.






27. A network that incorporates both optical fiber along with coaxial cable to create a broadband network. commonly used by cable tv companies.






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






29. 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






30. The extent of a certain item. For example - an address scope is also known as a range of addresses from beginning of the range to the end.






31. The IEEE 802.2 standard that defines the upper sublayer of the Ethernet Layer 2 specifications.






32. In a shared media ethernet network - a signal generated by the transmitting devices that detects the collision. The jam signal continue to transmit for a specified period to ensure that all devices on the network detect the collision. The jame signal






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






34. A name - as defined by DNS that uniquely identifies a computer in the internet. DNS servers can then respond to the DNS requests by supplying the IP address that is used by the computer that has a particular domain name. This term also refers to the






35. A network topology characterized by a central location connected to multiple hubs. In an extended star - these interconnected hubs may be connected to more hubs. It is essentially a hierarchical topology but typically is drawn with the central site i






36. Somtimes called place-value notation - this is a numeral system in which each position is related to the next by a constant multiplier - a common ration - called the base or radix of that numeral system.






37. 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






38. An encoding scheme 4B/5B uses 5-bit symbols and codes to represent 4 bits of data. 4B/5B is used in 100Base-tx ethernet.
