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 speed at which the access link is clocked. This choice affects the price of the connection and many aspects of traffic shaping and policing - compression - quality of service - and other configuration options.






2. Local Management Interface.






3. Data terminal equipment.






4. An enhanced version of WEP that is part of the 802.11i standard and has an automatic key-update mechanism that makes it much more secure than WEP. TKIP is not as strong as AES in terms of data protection.






5. Sending a message from a single source or multiple sources to selected multiple destinations across a Layer 3 network in one data stream.






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. Temporal Key Integrity Protocol.






8. Policing in which a single rate is metered - and packets are placed into one of two categories (conform or exceed).






9. Provider router.






10. An address type in IPv6 networks that is used only on the local link and never beyond that scope.






11. Class-Based Marking.






12. Cisco-proprietary STP feature in which an access layer switch is configured to be unlikely to become Root or to become a transit switch. Also - convergence upon the loss of the switch's Root Port takes place in a few seconds.






13. Per-Hop Behavior.






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






15. A standard (RFC 903) protocol by which a LAN-attached host can dynamically broadcast a request for a server to assign it an IP address. See also ARP.






16. A router that should not be used to forward packets between other routers. Other routers will not send Query messages to a stub router.






17. The process of breaking a frame into pieces - sending some of the fragments - and then sending all or part of a different packet - all of which is done to reduce the delay of the second packet.






18. A term relating to Cisco LAN switch tail-drop logic - in which multiple tail-drop thresholds may be assigned based on CoS or DSCP - resulting in some frames being discarded more aggressively than others.






19. A wireless LAN physical layer that operates at up to 11-Mbps data rates using DSSS in the 2.4-GHz band.






20. VLAN Trunking Protocol.






21. On a serial cable - the pin lead set by the DCE to imply that the DCE is ready to signal using pin leads






22. This term has two BGP-related definitions. First - it is the normal process in which a router - before sending an Update to an eBGP peer - adds its local ASN to the beginning of the AS_PATH path attribute. Second - it is the routing policy of purpose






23. 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.






24. High Density Binary 3.






25. An optimized Layer 3 forwarding path through a router. Fast switching optimizes routing table lookup by creating a special - easily searched table of known flows between hosts.






26. A BGP peer connection between two routers inside the same ASN - but in different confederation sub-autonomous systems.






27. Message Digest 5.






28. Extended Superframe.






29. A term referring to the processes and bits in the data stream used to manage the Telco TDM hierarchy.






30. Message sent by a PIM-DM router to its upstream router asking to quickly restart forwarding the group traffic; sent using the unicast address of the upstream router.






31. After a host receives an IGMP Query - the amount of time (default - 10 seconds) the host has to send the IGMP Report.






32. In OSPF - a number assigned to each LSA - ranging from 0x80000001 and wrapping back around to 0x7FFFFFFF - which is used to determine which LSA is most recent.






33. Modified Deficit Round-Robin.






34. The one VLAN on an 802.1Q trunk for which the endpoints do not add the 4-byte 802.1Q tag when transmitting frames in that VLAN.






35. Defined in RFC 826 - a protocol used on LANs so that an IP host can discover the MAC address of another device that is using a particular IP address.






36. A BGP path attribute that allows routers in one AS to set a value and advertise it into a neighboring AS - impacting the decision process in that neighboring AS. A smaller value is considered better. Also called the BGP metric.






37. An E-LSR in an MPLS VPN network whose role in a particular discussion is to receive labeled packets from other LSRs and then forward the packets as unlabeled packets to CE routers.






38. Timer An STP timer that dictates how long a port should stay in the listening state and the learning state.






39. Differentiated Services.






40. The OSPF data structure that describes topology information.






41. A set of four hex digits listed in an IPv6 address. Each quartet is separated by a colon.






42. The characterization of how far EIGRP Query messages flow away from the router that first notices a failed route and goes active for a particular subnet.






43. A conceptual model used by CB Policing when using an excess burst.






44. In the context of SNMP - the GetNext command is sent by an SNMP manager - to an agent - requesting the value of a single MIB variable. The GetNext request identifies a variable for which the manager wants the variable name and value of the next MIB l






45. With private VLANs - a port that can send and receive frames with all other ports in the private VLAN.






46. Area Border Router. An OSPF router that connects to the backbone area and to one or more non-backbone areas.






47. Sent by a PIM router to its upstream router to either request that the upstream router forward the group traffic or stop forwarding the group traffic that is currently being forwarded. If a PIM router wants to start receiving the group traffic - it l






48. The RMON function of tracking a particular variable. RMON events trigger RMON alarms.






49. A logical concept that represents the path over which frames travel between DTEs. VCs are particularly useful when comparing Frame Relay to leased physical circuits.






50. Virtual circuit.
