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 STP timer that dictates the interval at which the Root switch generates and sends Hello BPDUs.






2. With EIGRP - the metric value for the lowest-metric route to a particular subnet.






3. Defines a particular wireless LAN. The SSID configured in the radio card must match the SSID in the access point before the station can connect with the access point.






4. A standard (RFC 903) protocol by which a LAN-attached host can dynamically broadcast a request for a server to assign it an IP address. See also ARP.






5. An early standard from AT&T for encoding analog voice as a digital signal for transmission over a TDM network. PCM requires 64 kbps - and is the basis for the DS0 speed.






6. Aka network layer reachability information.






7. With some routing protocols - the time period between successive Hello messages.






8. Diffusing Update Algorithm.






9. Defined in RFC 2091 - the extensions define how RIP may send a full update once - and then send updates only when routes change - when an update is requested - or when a RIP interface changes state from down to up.






10. The Frame Relay protocol used between a DCE and DTE to manage the connection. Signaling messages for SVCs - PVC Status messages - and keepalives are all LMI messages.






11. An NTP client that assumes that a server will send NTP broadcasts - removing the requirement for the client to have the NTP server's IP address preconfigured.






12. Records client authentication and roaming events - which are sent to the CiscoWorks Wireless LAN Solution Engine (WLSE) to monitor client associations to specific access points.






13. Reported distance or Route Distinguisher.






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






15. One of the two modes of MDRR - in which the priority queue is serviced between each servicing of the non-priority queues.






16. A BGP router in an AS that uses route reflectors - but that is not aided by any RR server.






17. An OSPF external route for which internal OSPF cost is not added to the cost of the route as it was redistributed into OSPF.






18. A strategy for subnetting a classful network for which masks/prefixes are different for some subnets of that one classful network.






19. An OSPF external route for which internal OSPF cost is added to the cost of the route as it was redistributed into OSPF.






20. 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.






21. The number of beacons that governs how often multicast frames are sent over a wireless LAN.






22. A name used for DS1 lines inside the European TDM hierarchy.






23. Defined in IEEE 802.1d - a protocol used on LAN bridges and switches to dynamically define a logical network topology that allows all devices to be reached - but prevents the formation of loops.






24. Multicast addresses that are not assigned by IANA.






25. 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.






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






27. With RIP - the advertisement of a poisoned route out an interface - when that route was formerly not advertised out that interface due to split horizon rules.






28. Data Set Ready.






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






30. Cisco-proprietary VLAN trunking protocol.






31. A numeric value between 0 and 32 (inclusive) that defines the number of beginning bits in an IP address for which all IP addresses in the same group have the same value. Alternative: The number of binary 1s beginning a subnet mask - written as a deci






32. A dotted-decimal number used to help define the structure of an IP address. The binary 0s in the mask identify the host portion of an address - and the binary 1s identify either the combined network and subnet part (when thinking classfully) or the n






33. A tunneling protocol that can be used to encapsulate many different protocol types - including IPv4 - IPv6 - IPsec - and others - to transport them across a network.






34. Database Description.






35. Variable name for the time interval used by shapers and by CAR.






36. A Cisco-proprietary messaging protocol implemented in WAN switches that can be used to signal network status - including congestion - independent of end-user frames and cells.






37. The router in a VRRP group that is currently actively forwarding IP packets. Conceptually the same as an HSRP Active router.






38. A PPP feature used to load balance multiple parallel links at Layer 2 by fragmenting frames - sending one frame over each of the links in the bundle - and reassembling them at the receiving end of the link.






39. A neighbor state that signifies the other router has reached neighbor status - having passed the parameter check.






40. Wired Equivalent Privacy.






41. Router Advertisement.






42. Refers to how a router views a BGP peer relationship - in which the peer is in the same AS.






43. A multicast routing protocol that operates in dense mode and depends on the OSPF unicast routing protocol to perform its multicast functions.






44. A method for optimizing the flow of multicast IP packets passing through a LAN switch. The switch using IGMP snooping examines IGMP messages to determine which ports need to receive traffic for each multicast group.






45. On a serial cable - the pin lead set by the DCE to imply a working link.






46. Maximum transmission unit.






47. Link Control Protocol.






48. Inter-Switch Link.






49. Extended Superframe.






50. A TCP variable that defines the largest number of bytes allowed in a TCP segment's Data field. The calculation does not include the TCP header. With a typical IP MTU of 1500 bytes - the resulting default MSS would be 1460. TCP hosts must support an M
