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. Port Address Translation.






2. Multicast addresses that are not assigned by IANA.






3. Aka receiver's advertised window.






4. 64 bits at the end of an IPv6 global address - used to uniquely identify each host in a subnet.






5. The process of taking the IP - UDP - and RTP headers of a voice or video packet - compressing them - and then uncompressing them on the receiving router.






6. EAP over LAN.






7. An interface on a Cisco IOS-based switch that is treated as if it were an interface on a router.






8. Defined in RFC 826 - a protocol used on LANs so that an IP host can discover the MAC address of another device that is using a particular IP address.






9. 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.






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. In the PIM-SM design - the process by which a source DR - after it starts to receive the group traffic - encapsulates the multicast packets in the unicast packets and sends them to the RP.






12. In an IOS confederation configuration - the actual ASN as seen by eBGP peers.






13. Penultimate hop popping.






14. An IPv6 address format used for publicly registered IPv6 addresses.






15. Label Forwarding Information Base.






16. A subset of a classful IP network - as defined by a subnet mask - which used to address IP hosts on the same Layer 2 network in much the same way as a classful network is used.






17. Bipolar Violation.






18. Alternate name for the SPF algorithm - named for its inventor - Edsger W. Dijkstra.






19. Provides dynamic inspection of traffic as it traverses the router. It uses Context-Based Access Control (CBAC) to look deeper into a packet than an access list can. It tracks outbound traffic and dynamically allows in responses to that traffic.






20. Inverse ARP.






21. 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.






22. In MPLS VPNs - an entity in a single router that provides a means to separate routes in different VPNs. The VRF includes per-VRF instances of routing protocols - a routing table - and an associated CEF FIB.






23. A wireless LAN that offers connections to the Internet from public places - such as airports - hotels - and coffee shops.






24. A protocol used for reliable multicast and unicast transmissions. Used by EIGRP.






25. A process used in routers that are encrypting traffic to permit egress QoS actions to be taken on traffic that is being encrypted on that router. QoS pre-classification keeps a copy of each packet to be encrypted in memory long enough to take the app






26. Router-Port Group Management Protocol.






27. Data Terminal Ready.






28. The second byte of the IP header - formerly known as the ToS byte and redefined by DiffServ.






29. The range 232.0.0.0 through 232.255.255.255 that is allocated by IANA for SSM destination addresses and is reserved for use by source-specific applications and protocols.






30. A Cisco-proprietary protocol - used by LAN switches to communicate VLAN configuration.






31. 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






32. On a serial cable - the pin lead set by the DTE to tell the DCE that the DTE wants to send data.






33. On a serial cable - the pin lead set by the DCE to imply that the DCE is ready to signal using pin leads






34. The 32-bit number used to represent an OSPF router.






35. A method used by an IPv6 host to determine its own IP address - without DHCPv6 - by using NDP and the modified EUI-64 address format. See also stateful autoconfiguration.






36. The All OSPF DR Routers multicast IP address - listened for by DR and BDR routers.






37. From the perspective of one routing protocol - a route that was learned by using route redistribution.






38. Used by WRED to calculate the rate at which the average queue depth changes as compared with the current queue depth. The larger the number - the slower the change in the average queue depth.






39. AS number. A number between 1 and 64 -511 (public) and 64 -512 and 65 -535 (private) assigned to an AS for the purpose of identifying a specific BGP domain.






40. Wi-Fi Protected Access. A security standard that includes both TKIP and AES and was ratified by the Wi-Fi Alliance.






41. The All OSPF Routers multicast IP address - listened for by all OSPF routers.






42. The rate at which a policer limits the bits exiting or entering the policer.






43. A switch feature that examines incoming frames - comparing the source IP and MAC addresses to the DHCP snooping binding database - filtering frames whose addresses are not listed in the database for the incoming interface.






44. A 16-bit number set with a router config-register command. It is used to set several low-level features related mainly to accessing the router and what the router does when powered on.






45. A type of routing protocol convergence event in which the metric for a route increases slightly over time because of the advertisement of an invalid route.






46. An 802.1d STP port state in which the port sends and receives frames.






47. In the PIM-SM design - the central distribution point to which the multicast traffic is first delivered from the source designated router.






48. Jargon referring to a policer action through which - instead of discarding an out-of-contract packet - the policer marks a different IPP or DSCP value - allowing the packet to continue on its way - but making the packet more likely to be discarded la






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






50. A calculation of the length of the AS_PATH PA - which includes 1 for each number in the AS_SEQ - 1 for an entire AS_SET segment - and possibly other considerations.
