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. Variable-length subnet masking.






2. 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






3. A type of OSPF packet used to exchange and acknowledge LSA headers. Sometimes called DBD.






4. Aka receiver's advertised window.






5. A characteristic of OSPF interfaces that determines whether a DR election is attempted - whether or not neighbors must be statically configured - and the default Hello and Dead timer settings.






6. A message sent by the multicast router - by default every 60 seconds - on each of its LAN interfaces to determine whether any host wants to receive multicast traffic for any group.






7. 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






8. The combination of PVST+ and Rapid Spanning Tree. It provides subsecond convergence time and is compatible with PVST+ and MSTP.






9. Access Control Entry. An individual line in an ACL.






10. The process of taking the payload inside a Layer 2 frame - including the headers of Layer 3 and above - compressing the data - and then uncompressing the data on the receiving router.






11. The process of taking the IP and TCP headers of a packet - compressing them - and then uncompressing them on the receiving router.






12. A 3-tuple consisting of an IP address - port number - and transport layer protocol. TCP connections exist between a pair of sockets.






13. EIGRP jargon meaning that EIGRP has placed a route into active status.






14. Refers to how a router views a BGP peer relationship - in which the peer is in the same AS.






15. The first 4 bits of the first octet must be 1110. The last 28 bits are unstructured.






16. A Cisco IOS queuing tool that uses MQC configuration commands and reserves a minimum bandwidth for each queue.






17. An FRF standard for LFI for VoFR (FRF.11) VCs - in which all voice frames are interleaved in front of data frames' fragments.






18. 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.






19. A designated router that is directly connected with a source of the multicast group.






20. An event in which a new packet arrives - needing to be placed into a queue - and the queue is full






21. A definition that determines the data structure and information implied by a particular LSA.






22. Data communications equipment.






23. A WRED process by which WRED does not discard packets during times in which a queue's minimum threshold has not been passed.






24. Protocol Independent Multicast dense-mode routing protocol.






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






26. Network Address Translation-Protocol Translation.






27. In BGP - a set of routers inside a single administrative authority - grouped together for the purpose of controlling routing policies for the routes advertised by that group to the Internet.






28. 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.






29. Alternate name for the SPF algorithm - named for its inventor - Edsger W. Dijkstra.






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






31. A dotted-decimal number used to help define the structure of an IP address. The binary 0s in the mask identify the host portion of an address - and the binary 1s identify either the combined network and subnet part (when thinking classfully) or the n






32. The Cisco IOS feature by which special short key sequences can be used to move the cursor inside the current command line to more easily change a command.






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






34. 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.






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






36. A field within a route entry in a routing update - used to associate a generic number with the route. It is used when passing routes between routing protocols - allowing an intermediate routing protocol to pass information about a route that is not n






37. A well-known discretionary BGP path attribute that flags a route as being a summary route.






38. The process of combining multiple synchronized input signals over a single medium by giving each signal its own time slot - and then breaking out those signals.






39. Records client authentication and roaming events - which are sent to the CiscoWorks Wireless LAN Solution Engine (WLSE) to monitor client associations to specific access points.






40. Internal BGP.






41. 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.






42. Service set identifier.






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






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






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






46. Inverse ARP.






47. A Cisco IOS configuration tool - using the ip as-path access-list command - that defines a list of statements that match the AS_PATH BGP path attribute using regular expressions.






48. A method used by an IPv6 host to determine its own IP address - without DHCPv6 - by using NDP and the modified EUI-64 address format. See also stateful autoconfiguration.






49. Aka Rapid Per-VLAN Spanning Tree Plus.






50. Border Gateway Protocol.
