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 NAT term describing an IP address representing a host that resides inside the enterprise network - with the address being used in packets outside the enterprise network.






2. A mechanism that counters collisions caused by hidden nodes. If enabled - the station or access point must first send an RTS frame and receive a CTS frame before sending each data frame.






3. 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.






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






5. Out of Frame.






6. A term referring to the MQC class-map command and its related subcommands - which are used for classifying packets.






7. Backward Explicit Congestion Notification.






8. Label Forwarding Information Base.






9. An FRF standard for LFI for VoFR (FRF.11) VCs - in which all voice frames are interleaved in front of data frames' fragments.






10. Label Distribution Protocol.






11. In OSPF - a router that is prepared to take over the designated router.






12. Class-Based Weighted Fair Queuing.






13. The notation in a Cisco IOS IP routing table that identifies the route used by that router as the default route.






14. Link-State Acknowledgment.






15. Sent by a PIM router to its upstream router to either request that the upstream router forward the group traffic or stop forwarding the group traffic that is currently being forwarded. If a PIM router wants to start receiving the group traffic - it l






16. A BGP path attribute that is communicated throughout a single AS to signify which route of multiple possible routes is the best route to be taken when leaving that AS. A larger value is considered to be better.






17. An IPv6/IPv4 tunneling method that is designed for transporting IPv6 packets within a site where a native IPv6 infrastructures is not available.






18. With PIM on a multiaccess network - the PIM router with the highest IP address on the subnet. It is also the IGMPv1 Querier. The DR is responsible for the following tasks: - Sending PIM register and PIM join and prune messages toward the RP to infor






19. A term referring generically to ways in which a router or switch can determine whether a particular device or user should be allowed access.






20. With a routing update - or routing table entry - the portion of a route that defines the next router to which a packet should be sent to reach the destination subnet. With routing protocols - the Next Hop field may define a router other than the rout






21. Permanent virtual circuit.






22. Edge LSR.






23. Any OSPF neighbor for which the database flooding process has completed.






24. Provider edge.






25. A bit in the Frame Relay header that - when set to 1 - means that if a device needs to discard frames - it should discard the frames with DE 1 first.






26. Pulse code modulation.






27. An optimized Layer 3 forwarding path through a router. Fast switching optimizes routing table lookup by creating a special - easily searched table of known flows between hosts.






28. A logical group of content engines running WCCP between them. The lead content engine determines the traffic distribution within the cluster - for optimum performance and scalability.






29. The operating mode of shaped round-robin that provides a low-latency queue with policing.






30. Discard Eligible.






31. A type of spread spectrum that spreads RF signals over the frequency spectrum by transmitting the signal at different frequencies according to a hopping pattern. One of the original 802.11 physical layers used FHSS to offer data rates of 1 and 2 Mbps






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






33. Type of Service byte.






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






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






36. Forwarding Information Base.






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






38. A network/subnet to which only one OSPF router is connected.






39. A communication protocol between hosts and a multicast router by which routers learn of which multicast groups' packets need to be forwarded onto a LAN.






40. A Cisco IOS configuration tool for RIP and EIGRP for which the list matches routes in routing updates - and adds a defined value to the sent or received metric for the routes. The value added to the metric is the offset.






41. Digital Signal Level 1.






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






43. Superframe






44. Measured Round-Trip Time.






45. The first 6 bits of the DS field - used for QoS marking.






46. A routing protocol feature by which the routing update includes only routes that have changed - rather than include the entire set of routes.






47. Dynamic Multipoint VPN.






48. An E-LSR in an MPLS VPN network whose role in a particular discussion is to receive unlabeled packets over customer links and then forward the packets as labeled packets into the MPLS network.






49. From one perspective - DTE devices are one of two devices on either end of a communications circuit - specifically the device with less control over the communications. In Frame Relay - routers connected to a Frame Relay access link are DTE devices.






50. External BGP.
