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. A wireless LAN that includes the use of access points. Infrastructure mode connects wireless users to a wired network and allows wireless users to roam throughout a facility between different access points. All 802.11 data frames in an infrastructure






2. Secure Shell protocol used for character-oriented command-line access and configuration. A highly secure alternative to Telnet.






3. Aka network layer reachability information.






4. The initial 802.11 common key encryption mechanism; vulnerable to hackers.






5. A logical group of content engines running WCCP between them. The lead content engine determines the traffic distribution within the cluster - for optimum performance and scalability.






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






7. An early standard from AT&T for encoding analog voice as a digital signal for transmission over a TDM network. PCM requires 64 kbps - and is the basis for the DS0 speed.






8. 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.






9. 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.






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






11. A mapping between each DSCP value and a corresponding CoS value - often used in Cisco LAN switches when performing classification for egress queuing.






12. Port Aggregation Protocol.






13. Extended Superframe.






14. A Cisco IOS feature that performs deep packet inspection to classify packets based on application layer information.






15. With EIGRP - the metric value for the lowest-metric route to a particular subnet.






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






17. A group of devices on one or more LANs that are configured (using management software) so that they can communicate as if they were attached to the same wire - when - in fact - they are located on a number of different LAN segments. Because VLANs are






18. The range 239.0.0.0 through 239.255.255.255 that IANA has assigned for use in private multicast domains.






19. Orthogonal frequency division multiplexing.






20. Route Target.






21. An 802.1d STP port state in which the port sends and receives frames.






22. Defined in IEEE 802.1s - a specification for multiple STP instances when using 802.1Q trunks






23. 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






24. A workstation or server configured to collect and present RMON data for reporting purposes.






25. The SNMP specifications - standardized in RFCs - defining the rules by which SNMP MIB variables should be defined.






26. Designed to solve the problems of multicast duplication and multicast routing loops. For every multicast packet received - a multicast router examines its source IP address - consults its unicast routing table - determines which interface it would us






27. A type of OSPF stub area that - unlike stub areas - can inject external routes into the NSSA area.






28. The difference between the measured signal power and the noise power that a particular receiver sees at a given time. Higher SNRs generally indicate better performance.






29. Sent by a PIM router - by default every 30 seconds - on every interface on which PIM is configured to discover neighbors - establish adjacency - and maintain adjacency.






30. Any OSPF neighbor for which the database flooding process has completed.






31. A commonly used name for Multi-VRF CE.






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






33. The destination VLAN for an RSPAN session.






34. Differentiated Services.






35. A Cisco-proprietary STP implementation - created many years before IEEE 802.1s and 802.1w - that speeds convergence and allows for one STP instance for each VLAN.






36. Slow Start Threshold.






37. An 802.1w RSTP port state in which the port is not forwarding or receiving; covers 802.1d port states disabled - blocking - and listening.






38. Low-latency queuing.






39. Backup designated router.






40. Controls access to the Internet in public wireless LANs.






41. The condition in which a route has been in an EIGRP active state for longer than the router's Active timer.






42. 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.






43. On a multiaccess network - when a PIM-DM or PIM-SM router receives a Prune message - it starts a 3-second timer. If it receives a Join message on the multiaccess network from another router before the timer expires - it considers the message as an ov






44. A BGP process by which a router reapplies routing policy configuration (route maps - filters - and the like) based on stored copies of sent and received BGP Updates.






45. Network Control Protocol.






46. Defined in RFC 2289 - a mechanism by which a shared key and a secret key together feed into a hash algorithm - creating a password that is transmitted over a network. Because the shared key is not reused - the hash value is only valid for that indivi






47. An optional contention-free 802.11 access protocol that requires the access point to poll wireless stations before they are able to send frames. Not commonly implemented.






48. Weighted fair queuing.






49. Cisco IOS router feature by which a route map determines how to forward a packet - typically based on information in the packet other than the destination IP address.






50. With Spanning Tree Protocol - the single port on each LAN segment from which the best Hello BPDU is forwarded.
