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. 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.






2. 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






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






4. In the PIM-SM design - the process by which a PIM-SM router can build the SPT between itself and the source of a multicast group and take advantage of the most efficient path available from the source to the router as long as it has one directly conn






5. 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






6. 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.






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






8. A network/subnet over which two or more OSPF routers have become neighbors - thereby being able to forward packets from one router to another across that network.






9. Copper cable with RJ-45 connectors in which a twisted pair at pins 1 -2 on the first end of the cable is connected to pins 3 -6 on the other end - with a second pair connected to pins 3 -6 on the first end and pins 1 -2 on the other end.






10. Class-Based Weighted Fair Queuing.






11. Cisco-proprietary STP feature in which a switch port monitors for STP BPDUs of any kind - err-disabling the port upon receipt of any BPDU.






12. Excess Burst.






13. Another term for Port Address Translation. See PAT.






14. A characterization of a BGP path attribute in which all BGP implementations must support and understand the attribute (well known) - and all BGP Updates must include the attribute (mandatory).






15. Software-based collection and reporting tool for data reported by NetFlow.






16. An FRTS configuration construct - configured with the map-class frame-relay global configuration command.






17. 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.






18. A message that each host sends - either in response to a router Query message or on its own - to all multicast groups for which it would like to receive multicast traffic.






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






20. A BGP feature that defines the IP TTL field value in packets sent between two eBGP peers. This feature is required when using IP addresses other than the interface IP address on the link between peers.






21. The list of entries learned by the switch DHCP snooping feature. The entries include the MAC address used as the device's DHCP client address - the assigned IP address - the VLAN - and the switch port on which the DHCP assignment messages flowed.






22. Neighbor Discovery Protocol.






23. The definitions for a particular set of data variables - with those definitions following the SMI specifications. See also SMI.






24. 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.






25. 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.






26. A T1 alarm state that occurs when the receiver can no longer consistently identify the frame.






27. Label switched path.






28. Digital subscriber line - a common Internet service type for residential and business customers.






29. A message sent by each host - either in response to a router Query or on its own - to all multicast groups for which it would like to receive multicast traffic.






30. A wireless LAN physical layer that is backward compatible with 802.11b and operates at up to 54-Mbps data rates using OFDM in the 2.4-GHz band.






31. With RIP - a per-route timer - which is reset and grows with the Invalid timer. When the Flush timer mark is reached (default 240 seconds) - the router removes the route from the routing table - and now accepts any other routes about the failed subne






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






33. An FRF standard for Frame Relay-to-ATM Service Interworking in which one DTE uses Frame Relay and one uses ATM.






34. Operation - Administration - and Maintenance.






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






36. An 802.1d STP port state in which the port has been administratively disabled.






37. A Frame Relay traffic shaping feature during which the shaping rate is reduced when the shaper notices congestion through the receipt of BECN or ForeSight messages.






38. As defined in RFCs 2765 and 2766 - a method of translating between IPv4 and IPv6 that removes the need for hosts to run dual protocol stacks. NAT-PT is an alternative to tunneling IPv6 over an IPv4 network - or vice versa.






39. Voice over Frame Relay.






40. Low-latency queuing.






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






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






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






44. Cisco-proprietary STP feature in which switches use messaging to confirm the loss of Hello BPDUs in a switch's Root Port - to avoid having to wait for maxage to expire - resulting in faster convergence.






45. An FRF standard for payload compression.






46. An 802.1w RSTP port state in which the port is not the Root Port but is available to become the root port if the current root port goes down.






47. Multilayer Switching.






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. Inverse ARP.






50. Aka receiver's advertised window.
