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. Temporal Key Integrity Protocol.






2. Network Based Application Recognition.






3. In the context of SNMP - the Set command is sent by an SNMP manager - to an agent - requesting that the agent set a single identified variable to the stated value. The main purpose is to allow remote configuration and remote operation - such as shutt






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






5. Any routing protocol that uses the concept of using the SPF algorithm with an LSDB to compute routes.






6. In BGP - a configuration construct in which multiple neighbors' parameters can be configured as a group - thereby reducing the length of the configuration. Additionally - BGP performs routing policy logic against only one set of Updates for the entir






7. 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.






8. A protocol - defined in RFC 2865 - that defines how to perform authentication between an authenticator (for example - a router) and an authentication server that holds a list of usernames and passwords.






9. 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






10. 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.






11. A message sent by a multicast router - by default every 125 seconds - on each of its LAN interfaces to determine whether any host wants to receive multicast traffic for any group.






12. Provider edge.






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






14. Another name for Superframe.






15. Inverse ARP.






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






17. A Cisco IOS configuration tool for RIP and EIGRP for which the list matches routes in routing updates - and adds a defined value to the sent or received metric for the routes. The value added to the metric is the offset.






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






19. The protocol used by content engines to manage traffic flow between routers configured for WCCP and between content engines. WCCP takes advantage of the fact that many web pages (and other content) are regularly accessed by users in a given network.






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






21. Loss of Signal. A T1 alarm state that occurs when the receiver has not received any pulses of either polarity for a defined time period.






22. Classless interdomain routing.






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






24. 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.






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






26. Excess Burst.






27. The algorithm used by OSPF and IS-IS to compute routes based on the LSDB.






28. Exterior Gateway Protocol.






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






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






31. An IP variable that defines the largest size allowed in an IP packet - including the IP header. IP hosts must support an MTU of at least 576 bytes.






32. A dotted-decimal number that represents a subnet. It is the lowest numeric value in the range of IP addresses implied by a subnet number and prefix/mask.






33. Network Address Translation-Protocol Translation.






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






35. A wireless LAN physical layer that operates at up to 54-Mbps data rates using OFDM in the 5-GHz band.






36. 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.






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






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






39. Border Gateway Protocol.






40. A method of collecting traffic received on a switch port or a VLAN and sending it to specific destination ports on the same switch.






41. Class of Service.






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






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






44. WRED compares this setting to the average queue depth to decide whether packets should be discarded. No packets are discarded if the average queue depth falls below this minimum threshold.






45. Jargon used to refer to the first of two buckets in the dual token bucket model; its size is Bc.






46. Source-specific multicast.






47. An NTP mode in which an NTP host adjusts its clock in relation to an NTP server's clock.






48. With EIGRP - a purposefully slowly changing measurement of round-trip time between neighbors - from which the EIGRP RTO is calculated.






49. As defined in RFC 3623 - graceful restart allows for uninterrupted forwarding in the event that an OSPF router's OSPF routing process must restart. The router does this by first notifying the neighbor routers that the restart is about to occur; the n






50. A wireless LAN that only includes wireless users and no access points. 802.11 data frames in an ad hoc network travel directly between wireless users.
