Test your basic knowledge |

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. Weighted fair queuing.






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






3. Data Set Ready.






4. A list of interspersed alphanumeric literals and metacharacters that are used to apply complex matching logic to alphanumeric strings. Often used for matching AS_PATHs in Cisco routers.






5. Cisco Group Management Protocol.






6. Quantum value.






7. Designated router.






8. A characterization of a BGP path attribute in which BGP implementations are not required to support the attribute (optional) - and for which if a router receives a route with such an attribute - the router should forward the attribute unchanged (tran






9. With shaping - the number of bits allowed to be sent every Tc. Also defines the size of the token bucket when Be = 0.






10. A predefined VC. A PVC can be equated to a leased line in concept.






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






12. With DiffServ - a DSCP marking and a related set of QoS actions applied to packets that have that marking.






13. Internet Group Management Protocol.






14. The term to describe a router that is neither the DR nor the BDR on a subnet that elects a DR and BDR.






15. In IPv6 - the Neighbor Discovery message used by an IPv6 node to send information about itself to its neighbors.






16. The destination VLAN for an RSPAN session.






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






18. Removing unwanted VLANs from a Layer 2 path.






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






20. An Internet standard serial data-link protocol - used on synchronous and asynchronous links - that provides data-link framing - link negotiation - Layer 3 interface features - and other functions.






21. A BGP feature by which a router learns iBGP routes - and then forwards them to other iBGP peers - reducing the required number of iBGP peers while also avoiding routing loops.






22. 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






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






24. Similar to an appliance firewall - in that interfaces are placed into security zones. Traffic is allowed between interfaces in the same zone. You can apply policies to filter and control traffic between zones.






25. UniDirectional Link Detection.






26. 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






27. A component that interfaces with a phone using IP and provides connections to the Public Switched Telephone Network (PSTN).






28. The Cisco IOS Router IP Traffic Export feature - intended for intrusion detection - exports IP traffic that has signs of an attack - such as duplicate IP packets simultaneously received on two or more of a router's interfaces.






29. A mechanism that counters collisions caused by hidden nodes. If enabled - the station or access point must first send an RTS frame and receive a CTS frame before sending each data frame.






30. Per-Hop Behavior.






31. A term used with Cisco LAN switches - referring to a DSCP value used when making QoS decisions about a frame. This value may not be the actual DSCP value in the IP header encapsulated inside the frame.






32. Link Aggregation Control Protocol.






33. A characterization of a network attack in which packets flow to the attacker - and then out to the true recipient. As a result - the user continues to send data - increasing the chance that the attacker learns more and better information.






34. Weighted tail drop.






35. A type of OSPF packet used to discover neighbors - check for parameter agreement - and monitor the health of another router.






36. With EIGRP - for a particular route - the case in which the RD is lower than the FD.






37. Challenge Handshake Authentication Protocol.






38. WRED compares this setting to the average queue depth to decide whether packets should be discarded. All packets are discarded if the average queue depth rises above this maximum threshold.






39. 16 bits between the interface ID and global routing prefix in an IPv6 global address - used for subnet assignment inside an enterprise.






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






41. The protocol used in IPv6 for many functions - including address autoconfiguration - duplicate address detection - router - neighbor - and prefix discovery - neighbor address resolution - and parameter discovery.






42. The RMON function of sending a notification to an RMON collector or the console. Triggered by an RMON event.






43. Tag Distribution Protocol.






44. A type of spread spectrum that spreads RF signals over the frequency spectrum by transmitting the signal at different frequencies according to a hopping pattern. One of the original 802.11 physical layers used FHSS to offer data rates of 1 and 2 Mbps






45. VTP pruning.






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






47. Used to reserve network resources for a flow as it traverses the network. A device that creates an RSVP reservation guarantees that it can provide the bandwidth - latency - or other resources that are requested by RSVP.






48. A router that is allowed to receive a packet from an OSPF router and then forward the packet to another OSPF router.






49. A name used for DS1 lines inside the North American TDM hierarchy.






50. A set of DiffServ PHBs that defines 12 DSCP values - with four queuing classes and three drop probabilities within each queuing class.
