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. The PPP function for fragmenting packets - plus interleaving delay-sensitive later-arriving packets between the fragments of the first packet.






2. An 802.1d STP port state in which the port has been administratively disabled.






3. A BGP path attribute that lists ASNs through which the route has been advertised. The AS_PATH includes four types of segments: AS_SEQ - AS_SET - AS_CONFED_SEQ - and AS_CONFED_SET. Often - this term is used synonymously with AS_SEQ






4. A Cisco IOS queuing tool most notable for its reservation of a minimum bandwidth for each queue.






5. On a single computer - one layer provides a service to a higher layer. The software or hardware that implements the higher layer requests that the next lower layer perform the needed function.






6. A Cisco IOS queuing tool that uses MQC configuration commands - reserves a minimum bandwidth for some queues - provides high-priority scheduling for some queues - and polices those queues to prevent starvation of lower-priority queues during interfac






7. An NTP client that assumes that a server will send NTP broadcasts - removing the requirement for the client to have the NTP server's IP address preconfigured.






8. The Lempel Ziv STAC compression algorithm is used in Frame Relay networks to define dynamic dictionary entries that list a binary string from the compressed data and an associated smaller string that represents it during transmission






9. A serial-line encoding standard that sends alternating positive and negative 3-volt signals for binary 1 - and no signal (0 V) for binary 0.






10. The 802.1X driver that supplies a username/password prompt to the user and sends/receives the EAPoL messages.






11. A BGP feature by which a router learns iBGP routes - and then forwards them to other iBGP peers - reducing the required number of iBGP peers while also avoiding routing loops.






12. A Cisco-proprietary LMI protocol - implemented in Cisco WAN switches and routers - through which the switch can inform the router about parameters for each VC - including CIR - Bc - and Be.






13. Instead of advertising all routes out a particular interface - the routing protocol omits the routes whose outgoing interface field matches the interface out which the update would be sent.






14. Multicast addresses that are not assigned by IANA.






15. In 802.1X - the computer that stores usernames/passwords and verifies that the correct values were submitted before authenticating the user.






16. A BGP feature that overcomes the requirement of a full mesh of iBGP peers inside a single AS by separating the AS into multiple sub-autonomous systems.






17. Priority queue and priority queuing.






18. A NAT term describing an IP address representing a host that resides inside the enterprise network - with the address being used in packets inside the enterprise network.






19. A network/subnet over which two or more OSPF routers have become neighbors - thereby being able to forward packets from one router to another across that network.






20. A type of IPv4 and IPv6 traffic designed primarily to provide one-to-many connectivity but unlike broadcast - has the capability to control the scope of traffic distribution.






21. An OSPF area into which external (type 5) LSAs are not introduced by its ABRs; instead - the ABRs originate and inject default routes into the area.






22. The process of forwarding packets through a router. Also call IP routing.






23. Edge LSR.






24. A TCP variable that defines the largest number of bytes allowed in a TCP segment's Data field. The calculation does not include the TCP header. With a typical IP MTU of 1500 bytes - the resulting default MSS would be 1460. TCP hosts must support an M






25. An FRF standard for Frame Relay-to-ATM Service Interworking in which both DTEs use Frame Relay - with ATM in between.






26. A queue created by Cisco IOS as a result of the configuration of a queuing tool.






27. An IP variable that defines the largest size allowed in an IP packet - including the IP header. IP hosts must support an MTU of at least 576 bytes.






28. Copper cable with RJ-45 connectors in which the wire at pin 1 on one end is connected to pin 1 on the other end; the wire at pin 2 is connected to pin 2 on the other end; and so on.






29. The command used to initialize a SPAN or RSPAN session on a Catalyst switch.






30. An exterior routing protocol designed to exchange prefix information between different autonomous systems. The information includes a rich set of characteristics called path attributes - which in turn allows for great flexibility regarding routing ch






31. An ITU standard Frame Relay header - including the DLCI - DE - FECN - and BECN bits in the LAPF header - and a frame check in the LAPF trailer.






32. An IEEE standard that - when used with EAP - provides user authentication before their connected switch port allows the device to fully use the LAN.






33. An NTP mode in which an NTP host adjusts its clock in relation to an NTP server's clock.






34. Receivers subscribe to an (S -G) channel when they request to join a multicast group. That is - they specify the unicast IP address of their multicast source and the group multicast address. SSM is typically used in very large multicast deployments s






35. Ethernet process by which devices attached to the same cable negotiate their speed and the duplex settings over the cable.






36. Jargon referring to the minimum value to which adaptive shaping will lower the shaping rate.






37. Each 802.11 station passively monitors each RF channel for a specific amount of time and listens for beacons. Stations use the signal strengths of found beacons to determine the access point or ad hoc network with which to attempt association.






38. Out of Frame.






39. Clear To Send.






40. In IPv6 - an address used in the Neighbor Discovery (ND) process. The format for these addresses is FF02::1:FF00:0000/104 - and each IPv6 host must join the corresponding group for each of its unicast and anycast addresses.






41. Backup designated router.






42. Link-state advertisement.






43. A characterization of a BGP path attribute in which all BGP implementations must support and understand the attribute (well known) - but BGP Updates can either include the attribute or not depending on whether a related feature has been configured (d






44. An IPv6 address format used for publicly registered IPv6 addresses.






45. A BGP ASN whose value is between 64 -512 and 65 -535. These values are not assigned for use on the Internet - and can be used for private purposes - typically either within confederations or by ISPs to hide the ASN used by some customers.






46. A set of DiffServ PHBs that defines 12 DSCP values - with four queuing classes and three drop probabilities within each queuing class.






47. The practice of defining boundaries that determine how far multicast traffic will travel in your network.






48. A name used for DS3 lines inside the North American TDM hierarchy.






49. A basic form of traffic shaping that is applied to an interface or subinterface. By default - it shapes all traffic leaving the interface - but can be modified by using an access control list. The access list controls only what traffic is shaped; GTS






50. Web Cache Communication Protocol.
