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






2. In two-rate policing - the second and higher rate defined to the policer.






3. Aka Rapid Per-VLAN Spanning Tree Plus.






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. Version 4 of the IP protocol - which is the generally deployed version worldwide (at publication) - and uses 32-bit IP addresses.






6. The structure inside telcos' original digital circuit build-out in the mid-1900s - based upon using TDM to combine and disperse smaller DS levels into larger levels - and vice versa.






7. Secure Copy Protocol - one of the many ways of transferring files to and from Cisco IOS routers and switches.






8. A mapping between each DSCP value and a corresponding CoS value - often used in Cisco LAN switches when performing classification for egress queuing.






9. Authentication - authorization - and accounting.






10. Switched virtual circuit.






11. Each 802.11 station periodically sends a probe request frame on each RF channel and monitors probe response frames that all access points within range send back. Stations use the signal strength of the probe response frames to determine which access






12. The most significant bit in the most significant byte of an Ethernet MAC address - its value implies that the address is a unicast MAC address (binary 0) or not (binary 1).






13. Direct sequence spread spectrum.






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






15. The process of running the SPF algorithm against the LSDB - with the result being the determination of the current best route(s) to each subnet.






16. A BGP router that forwards iBGP-learned routes to other iBGP routers.






17. 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.






18. With EIGRP - the timer used to determine when a neighboring router has failed - based on a router not receiving any EIGRP messages - including Hellos - in this timer period.






19. 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.






20. Differentiated Services.






21. A Cisco IOS queuing tool that uses MQC configuration commands - reserves a minimum bandwidth for some queues - provides high-priority scheduling for some queues - and polices those queues to prevent starvation of lower-priority queues during interfac






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






23. A Cisco IOS queuing tool most notable for its reservation of a minimum bandwidth for each queue.






24. Cisco-proprietary STP feature in which an access layer switch is configured to be unlikely to become Root or to become a transit switch. Also - convergence upon the loss of the switch's Root Port takes place in a few seconds.






25. Modified Deficit Round-Robin.






26. Multicast addresses that are not assigned by IANA.






27. A set of all devices that receive broadcast frames originating from any device within the set. Devices in the same VLAN are in the same broadcast domain.






28. A 48-bit address that is calculated from a Layer 3 multicast address by using 0x0100.5E as the multicast vendor code (OUI) for the first 24 bits - always binary 0 for the 25th bit - and copying the last 23 bits of the Layer 3 multicast address.






29. Cisco Express Forwarding.






30. A 3-bit field in an 802.1Q header used for marking frames.






31. An EIGRP router's reaction to an input event - leading to the use of a feasible successor or going active on a route.






32. In wireless LANs - a mechanism that counters issues related to RF interference by dividing a larger 802.11 data frame into smaller frames that are sent independently to the destination. See also LFI.






33. Instead of advertising all routes out a particular interface - the routing protocol omits the routes whose outgoing interface field matches the interface out which the update would be sent.






34. 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






35. Link Fragmentation and Interleaving.






36. 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.






37. Challenge Handshake Authentication Protocol.






38. 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.






39. Network Address Translation.






40. The mandatory contention-based 802.11 access protocol that is also referred to as CSMA/CA.






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






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






43. An optional transitive BGP path attribute used to store 32-bit decimal values. Used for flexible grouping of routes by assigning the group the same COMMUNITY value. Other routers can apply routing policies based on the COMMUNITY value. Used in a larg






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






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. A set of parameters for CBAC to perform in its traffic inspection process.






47. With routing protocols - the measurement of favorability that determines which entry will be installed in a routing table if more than one router is advertising that exact network and mask.






48. In Frame Relay - a link between a router and a Frame Relay switch.






49. Provider router.






50. Used by a policer to classify packets relative to the traffic contract. These packets are considered to be above the traffic contract in all cases.
