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 Layer 3 forwarding path through a router that does not optimize the forwarding path through the router.






2. In the context of SNMP - the GetBulk command is sent by an SNMP manager - to an agent - requesting the values of multiple variables. The GetBulk command allows retrieval of complex structures - like a routing table - with a single command - as well a






3. Source-specific multicast.






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






5. Cisco Group Management Protocol.






6. Defined in FRF.11 - an FR VC that uses a slightly varied header - as compared with FRF.3 data VCs - to accommodate voice payloads directly encapsulated inside the Frame Relay LAPF header.






7. Per-VLAN Spanning Tree Plus.






8. An Internet standard authentication protocol that uses clear-text passwords and a two-way handshake to perform authentication over a PPP link.






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






10. Committed information rate.






11. A type of routing protocol convergence event in which the metric for a route increases slightly over time because of the advertisement of an invalid route.






12. Jargon used to refer to the second of two buckets in the dual token bucket model; its size is Be.






13. A routing protocol feature for which the routing protocol sends routing updates immediately upon hearing about a changed route - even though it may normally only send updates on a regular update interval.






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






15. Inside telcos' original TDM hierarchy - a unit that combines multiple DS0s into a single channel






16. Multilayer Switching.






17. Router ID.






18. An NTP mode in which an NTP host does not adjust its clock - but in which it sends NTP messages to clients so that the clients can update their clocks based on the server's clock.






19. Time Interval.






20. An Internet standard authentication protocol that uses secure hashes and a three-way handshake to perform authentication over a PPP link.






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






22. Jargon referring to a policer action through which - instead of discarding an out-of-contract packet - the policer marks a different IPP or DSCP value - allowing the packet to continue on its way - but making the packet more likely to be discarded la






23. Alarm Indication Signal. With T1s - the practice of sending all binary 1s on the line in reaction to problems - to provide signal transitions and allow recovery of synchronization and framing.






24. In switch port security - the process whereby the switch dynamically learns the MAC address(es) of the device(s) connected to a switch port - and then adds those addresses to the running configuration as allowed MAC addresses for port security.






25. When subnetting a class A - B - or C address - the subnet for which all subnet bits are binary 0.






26. Network Time Protocol.






27. Aka minimum CIR.






28. A T1 alarm state that occurs when a device receives a Yellow Alarm signal. This typically means that the device on the other end of the line is in a Red Alarm state.






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






30. A term used in this book to refer to a route that is included in a larger summary route.






31. A problem that occurs when an AS does not run BGP on all routers - with synchronization disabled. The routers running BGP may believe they have working routes to reach a prefix - and forward packets to internal routers that do not run BGP and do not






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






33. Border Gateway Protocol.






34. 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.






35. Data Carrier Detect.






36. An IPv6 migration strategy in which a host or router supports both IPv4 and IPv6 natively.






37. 64 bits at the end of an IPv6 global address - used to uniquely identify each host in a subnet.






38. A single address in each subnet for which packets sent to this address will be broadcast to all hosts in the subnet. It is the highest numeric value in the range of IP addresses implied by a subnet number and prefix/mask.






39. Used by RRs to denote the RID of the iBGP neighbor that injected the NLRI into the AS.






40. Modified Deficit Round-Robin.






41. The rate at which a shaper limits the bits exiting the shaper.






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






43. A term referring to how a router views a BGP peer relationship - in which the peer is in another AS.






44. Often used synonymously with neighbor - but with emphasis on the fact that all required parameters match - allowing routing updates to be exchanged between the routers.






45. The second most significant bit in the most significant byte of an Ethernet MAC address - a value of binary 0 implies that the address is a Universally Administered Address (UAA) (also known as Burned-In Address [BIA]) - and a value of binary 1 impli






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






47. The IP address to which Label Distribution Protocol (LDP) sends LDP Hellos. Also used in IP multicast to send packets to all multicast routers.






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






49. Cisco-proprietary STP feature in which switches use messaging to confirm the loss of Hello BPDUs in a switch's Root Port - to avoid having to wait for maxage to expire - resulting in faster convergence.






50. An 802.1w RSTP port state in which the port is an alternative Designated Port on some LAN segment.
