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. AutoQoS is a macro that creates and applies quality of service configurations based on Cisco best-practice recommendations.






2. EAP over LAN.






3. In IP routing - a term referring to the building of IP routing tables by IP routing protocols.






4. A type of OSPF packet used to acknowledge LSU packets.






5. A switch feature in which the switch examines DHCP messages and - for untrusted ports - filters all messages typically sent by servers and inappropriate messages sent by clients. It also builds a DHCP snooping binding table that is used by DAI and IP






6. Penultimate hop popping.






7. A state for a route in an EIGRP topology table that indicates that the router believes that the route is stable - and it is not currently looking for any new routes to that subnet.






8. The innermost MPLS header in an packet traversing an MPLS VPN - with the label value identifying the forwarding details for the egress PE's VRF associated with that VPN.






9. A term referring to the MQC class-map command and its related subcommands - which are used for classifying packets.






10. WRED compares this setting to the average queue depth to decide whether packets should be discarded. No packets are discarded if the average queue depth falls below this minimum threshold.






11. Sequence number.






12. The specific frequency subband on which the radio card or access point is operating. The RF channel is set in the access point or ad hoc stations.






13. Multicast addresses that are not assigned by IANA.






14. A TCP variable used as the basis for a TCP sender's timer defining how long it should wait for a missing acknowledgement before resending the data.






15. The content engine in a WCCP cluster - which determines how traffic will be distributed within the cluster.






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






17. Hot Standby Router Protocol.






18. Extended Superframe.






19. RFC 1918-defined IPv4 network numbers that are not assigned as public IP address ranges - and are not routable on the Internet. Intended for use inside enterprise networks.






20. Inside telcos' original TDM hierarchy - the smallest unit of transmission at 64 kbps.






21. Copper cable with RJ-45 connectors in which a twisted pair at pins 1 -2 on the first end of the cable is connected to pins 3 -6 on the other end - with a second pair connected to pins 3 -6 on the first end and pins 1 -2 on the other end.






22. An OSPF router that connects to the backbone area and to one or more non-backbone area.






23. An IPv6/IPv4 tunneling method that is designed for transporting IPv6 packets within a site where a native IPv6 infrastructures is not available.






24. Regeneration of the Layer 2 encapsulation removed from frames forwarded in a SPAN session.






25. Data communications equipment.






26. A term used with Cisco LAN switches - referring to a queue treated with strict-priority scheduling.






27. A bit inside the Frame Relay header that - when set - implies that congestion occurred in the direction opposite (or backward) as compared with the direction of the frame.






28. A mechanism in which VLAN information can extend over another set of 802.1Q trunks by tunneling the original 802.1Q traffic with another 802.1Q tag. It allows a service provider to support transparent VLAN services with multiple customers - even if t






29. Burst With shaping and policing - the number of additional bits that may be sent after a period of relative inactivity.






30. A DiffServ PHB - based on DSCP EF (decimal 46) - that provides low-latency queuing behavior as well as policing protection to prevent EF traffic from starving queues for other types of traffic.






31. In MPLS VPNs - a 64-bit Extended Community path attribute attached to a BGP route for the purpose of controlling into which VRFs the route is added.






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






33. Spanning Tree Protocol.






34. When subnetting a class A - B - or C address - the subnet for which all subnet bits are binary 1.






35. Weighted random early detection.






36. 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






37. The definitions for a particular set of data variables - with those definitions following the SMI specifications. See also SMI.






38. 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.






39. A technology that enables frequency reuse. Two variants exist: frequency hopping (FHSS) and direct sequence (DSSS). Both techniques spread the signal power over a relatively wide portion of the frequency spectrum over time - to reduce interference be






40. Distance Vector Multicast Routing Protocol.






41. Secure Copy Protocol - one of the many ways of transferring files to and from Cisco IOS routers and switches.






42. Variable name for the time interval used by shapers and by CAR.






43. A type of OSPF stub area for which neither external (type 5) LSAs are introduced - nor type 3 summary LSAs; instead - the ABRs originate and inject default routes into the area. External routes cannot be injected into a totally stubby area.






44. Router-Port Group Management Protocol.






45. The second byte of the IP header - formerly known as the ToS byte and redefined by DiffServ.






46. A Cisco IOS queuing tool most notable for its automatic classification of packets into separate per-flow queues.






47. Point-to-Point Protocol over Ethernet. A convention often used as the data link protocol over Cable in which Ethernet is used as the data link protocol - but with PPP being encapsulated inside Ethernet. The combination gives the data link features of






48. WRED compares this setting to the average queue depth to decide whether packets should be discarded. All packets are discarded if the average queue depth rises above this maximum threshold.






49. Reduces the bandwidth necessary for radio management information - such as access point status messages - that is sent across the network by eliminating redundant management information.






50. A T1 alarm state that occurs when the receiver can no longer consistently identify the frame.
