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






2. The process of sending an infinite-metric route in routing updates when that route fails.






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






4. A Cisco switch feature that allows separation of ports as if they were in separate VLANs - while allowing the use of a single IP subnet for all ports.






5. A bit in the LAPF Frame Relay header that - when set to 1 - implies that the frame has experienced congestion.






6. An MQC-based feature of IOS that is used to classify and mark packets for QoS purposes.






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






8. An 802.1d STP port state in which the port does not send or receive frames - except for listening for received Hello BPDUs.






9. In IP routing - a term referring to the process of forwarding packets through a router.






10. A Cisco IOS configuration tool that can be used to match routing updates based on a base network address - a prefix - and a range of possible masks used inside the values defined by the base network address and prefix.






11. Time to Live.






12. Cell Loss Priority.






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






14. Autonomous System Boundary Router. An OSPF router that redistributes routes from some other source into OSPF.






15. 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






16. 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.






17. Virtual LAN.






18. In MPLS - a term used to define a label that an LSR learned from a neighboring LSR.






19. Per-Hop Behavior.






20. A reserved value for the BGP COMMUNITY path attribute that implies that the route should not be advertised outside the local confederation sub-AS.






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






22. The router that will receive the group traffic when a multicast router forwards group traffic to another router.






23. Label Switch Router.






24. A process on a computing device that issues requests for SNMP MIB variables from SNMP agents - receives and processes the MIB data - and accepts unsolicited Trap messages from SNMP agents.






25. Defined in RFC 3748 - the protocol used by IEEE 802.1X for exchanging authentication information.






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






27. A BGP process by which a router reapplies routing policy configuration (route maps - filters - and the like) based on stored copies of sent and received BGP Updates.






28. The process of taking the payload inside a Layer 2 frame - including the headers of Layer 3 and above - compressing the data - and then uncompressing the data on the receiving router.






29. Area 0; the area to which all other OSPF areas much connect in order for OSPF to work.






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






31. In MQC and CB Policing - a configuration style by which - for one category of packets (conform - exceed - or violate) - more than one marking action is defined for a single category. For example - marking DSCP and DE.






32. The initial 802.11 common key encryption mechanism; vulnerable to hackers.






33. Ethernet MAC address that represents all devices on the LAN.






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






35. 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.






36. 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.






37. A Cisco router feature in which the router works to prevent SYN attacks either by monitoring TCP connections flowing through the router - or by actively terminating TCP connection until the TCP connection is established and then knitting the client-s






38. Data-link connection identifier.






39. Calculated measurement based on the actual queue depth and the previous average. Designed to allow WRED to adjust slowly to rapid changes of the actual queue depth.






40. Defined in RFC 1293 - this protocol allows a Frame Relay-attached device to react to a received LMI "PVC up" message by announcing its Layer 3 addresses to the device on the other end of the PVC.






41. An enhanced version of WEP that is part of the 802.11i standard and has an automatic key-update mechanism that makes it much more secure than WEP. TKIP is not as strong as AES in terms of data protection.






42. The process of taking a PDU from some other source and placing a header in front of the original PDU - and possibly a trailer behind it.






43. The portions of PPP focused on features that are related to specific Layer 3 protocols.






44. The MD5-encoded password defined by the enable secret command.






45. Multicast addresses that are not assigned by IANA.






46. Layer 2 payload compression.






47. A mechanism for conserving battery power in wireless stations. The access point buffers data frames destined to sleeping stations - which wake periodically to learn from information in the beacon frame whether or not data frames are waiting for trans






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






49. 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.






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