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. Auto-Rendezvous Point. Cisco-proprietary protocol that can be used to designate an RP and send RP-Announce messages that advertise its IP address and groups. Also - it can be used to designate a mapping agent that interprets what IP address RP is adv






2. An Internet standard (RFC 1305) that defines the messages and modes used for IP hosts to synchronize their time-of-day clocks.






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






4. EIGRP (and IGRP) allows for the use of bandwidth - load - delay - MTU - and link reliability; the K values refer to an integer constant that includes these five possible metric components. Only bandwidth and delay are used by default - to minimize re






5. A state variable kept by a router for each known neighbor or potential neighbor.






6. The underlying algorithms associated with RIP.






7. With EIGRP - a route that is not a successor route - but that meets the feasibility condition; can be used when the successor route fails - without causing loops.






8. In BGP - either external BGP (eBGP) - confederation eBGP - or internal BGP (iBGP). The term refers to a peer connection - and whether the peers are in different ASs (eBGP) - different confederation sub-ASs (confederation eBGP) - or in the same AS (iB






9. A set of packets in an MPLS network for which the MPLS network will apply the exact same forwarding behavior.






10. Reported distance or Route Distinguisher.






11. A name used for DS3 lines inside the European TDM hierarchy.






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






13. The ASN assigned to a confederation sub-AS.






14. Defines a particular behavior for FTP regarding the establishment of data TCP connections. In active mode - the FTP client uses the FTP PORT command - over the FTP control connection - to tell the FTP server the port on which the client should be lis






15. Backup designated router.






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






17. With EIGRP - the route to each destination for which the metric is the lowest of all known routes to that network.






18. 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.






19. In the PIM-SM design - the process by which a source DR - after it starts to receive the group traffic - encapsulates the multicast packets in the unicast packets and sends them to the RP.






20. 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.






21. A VC that is set up dynamically when needed. An SVC can be equated to a dial-on-demand connection in concept.






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






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






24. An MQC configuration style by which one policy map calls a second policy map. For example - a shaping policy map can call an LLQ policy map to implement LLQ for packets shaped by CB Shaping.






25. Orthogonal frequency division multiplexing.






26. With private VLANs - a secondary VLAN in which the ports can send and receive frames with each other - but not with ports in other secondary VLANS.






27. A BGP message that includes withdrawn routes - path attributes - and NLRI.






28. 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.






29. 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.






30. Point-to-Point Protocol.






31. An NTP mode in which two or more NTP servers mutually synchronize their clocks.






32. AutoQoS is a macro that creates and applies quality of service configurations based on Cisco best-practice recommendations.






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






34. Digital Signal Level 0.






35. 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.






36. Inter-Switch Link.






37. Defined in IEEE 802.1AD - defines a messaging protocol used to negotiate the dynamic creation of PortChannels (EtherChannels) and to choose which ports can be placed into an EtherChannel.






38. DCE devices are one of two devices on either end of a communications circuit - specifically the device with more control over the communications. Frame Relay switches are DCE devices. DCEs are also known as data circuit-terminating equipment (DTE).






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






40. 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.






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






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






43. An exterior routing protocol that predates BGP. It is no longer used today.






44. A standards-based way of helping routers find Rendezvous Points (RP). RPs notify BSRs of the groups they handle. BSRs in turn flood the group-to-RP mappings throughout the network. Each router individually determines which RP to use for a particular






45. A process used in routers that are encrypting traffic to permit egress QoS actions to be taken on traffic that is being encrypted on that router. QoS pre-classification keeps a copy of each packet to be encrypted in memory long enough to take the app






46. 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.






47. Receiver's advertised window.






48. Defines a particular behavior for FTP regarding the establishment of TCP data connections. In passive mode - an FTP server uses the FTP PORT command - over the FTP control connection - to tell the FTP client the port on which the server will be liste






49. In MPLS VPNs - a 64-bit Extended Community path attribute attached to a BGP route for the purpose of controlling into which VRFs the route is added.






50. Multicast Open Shortest Path First.
