CCIE Vocab

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 MD5-encoded password defined by the enable secret command.






2. An intrusion detection system that safeguards the wireless LAN from malicious and unauthorized access.






3. Network Time Protocol.






4. The process of installing a multicast application; also referred to as launching an application.






5. Bipolar 8 Zero Substitution. A serial-line encoding standard that substitutes Bipolar Violations in a string of eight binary 0s to provide enough signal transitions to maintain synchronization.






6. The combination of MPLS labels and links over which a packet will be forwarded over an MPLS network - from the point of ingress to the MPLS network to the point of egress.






7. With EIGRP - the metric (distance) of a route as reported by a neighboring router.






8. A vendor consortium that formerly worked to further Frame Relay common vendor standards.






9. A Cisco-proprietary BGP feature. The administrative weight can be assigned to each NLRI and path locally on a router - impacting the local router's choice of the best BGP routes. The value cannot be communicated to another router.






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






11. Operates in dense mode and depends on its own unicast routing protocol that is similar to RIP to perform its multicast functions.






12. Version 6 of the IP protocol - which uses 128-bit IP addresses.






13. Inverse ARP.






14. Port Address Translation.






15. An issue whereby parts of the RF signal take different paths from the source to the destination - which causes direct and reflected signals to reach the receiver at different times - and corresponding bit errors.






16. With EIGRP - a purposefully slowly changing measurement of round-trip time between neighbors - from which the EIGRP RTO is calculated.






17. The number of beacons that governs how often multicast frames are sent over a wireless LAN.






18. An FRF standard for LFI for data (FRF.3) VCs.






19. A term used with WFQ for the number assigned to a packet as it is enqueued into a WFQ. WFQ schedules the currently lowest SN packet next.






20. An architecture and set of documents that defines Cisco's best recommendations for how to secure a network.






21. Uses Modular QoS CLI to control the amount and type of traffic handled by the router or switch control plane. Class maps identify traffic types - and then a service policy applied to the device control plane sets actions for each type of traffic.






22. 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.






23. Maximum transmission unit.






24. The first 6 bits of the DS field - used for QoS marking.






25. An EIGRP message that is used by a router to notify its neighbors when the router is gracefully shutting down.






26. A mapping between each DSCP value and a WRED threshold - often used in Cisco LAN switches when performing WRED.






27. Alternate Mark Inversion. 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.






28. Diffusing Update Algorithm.






29. A PPP feature used to load balance multiple parallel links at Layer 2 by fragmenting frames - sending one frame over each of the links in the bundle - and reassembling them at the receiving end of the link.






30. A wireless LAN physical layer that operates at up to 54-Mbps data rates using OFDM in the 5-GHz band.






31. Enhances RP redundancy by providing a method for RPs to exchange multicast source information - even between multicast domains.






32. A type of logic for how a router uses a default route. When a default route exists - and the class A - B - or C network for the destination IP address does not exist in the routing table - the default route is used. If any part of that classful netwo






33. In wireless LANs - a mechanism that counters issues related to RF interference by dividing a larger 802.11 data frame into smaller frames that are sent independently to the destination. See also LFI.






34. A method of obtaining an IPv6 address that uses DHCPv6. See also stateless autoconfiguration.






35. Request-to-send/clear-to-send.






36. Virtual Router Redundancy Protocol.






37. Service set identifier.






38. Another name for 802.1Q-in-Q. See 802.1Q-in-Q.






39. In the PIM-SM design - the process by which a PIM-SM router can build the SPT between itself and the source of a multicast group and take advantage of the most efficient path available from the source to the router as long as it has one directly conn






40. The process of taking routes known through one routing protocol and advertising those routes with another routing protocol.






41. The multicast IP address 224.0.0.6 - listened for by DR and BDR routers.






42. A process whereby a switch - when making a forwarding decision - uses not only Layer 2 logic but other OSI layer equivalents as well.






43. 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.






44. Defined in RFCs 1517-1520 - a scheme to help reduce Internet routing table sizes by administratively allocating large blocks of consecutive classful IP network numbers to ISPs for use in different global geographies. CIDR results in large blocks of n






45. Router Advertisement.






46. Feasible distance.






47. Network Address Translation-Protocol Translation.






48. An attack similar to a smurf attack - but using packets for the UDP Echo application instead of ICMP.






49. A Cisco-proprietary protocol that defines how to perform authentication between an authenticator (for example - a router) and an authentication server that holds a list of usernames and passwords.






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