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






2. Network Address Translation-Protocol Translation.






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






4. An 802.11 frame that access points or stations in ad hoc networks send periodically so that wireless stations can discover the presence of a wireless LAN and coordinate use of certain protocols - such as power-save mode.






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






6. Penultimate hop popping.






7. Time Interval.






8. A wireless LAN physical layer that operates at up to 11-Mbps data rates using DSSS in the 2.4-GHz band.






9. Feasible distance.






10. The most significant bit in the most significant byte of an Ethernet MAC address - its value implies that the address is a unicast MAC address (binary 0) or not (binary 1).






11. A 3-bit field in an MPLS header used for marking frames.






12. Exterior Gateway Protocol.






13. Link-state database.






14. In Frame Relay - a link between a router and a Frame Relay switch.






15. Class of Service.






16. A bit inside the Frame Relay header that - when set - implies that congestion occurred in the direction opposite (or backward) as compared with the direction of the frame.






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






18. Voice over Frame Relay.






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






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






21. A Cisco-proprietary feature by which multiple routers can provide interface IP address redundancy - as well as cause a set of clients to load-balance their traffic across multiple routers inside the GLBP group.






22. A Cisco IOS feature that provides reporting information to a NetFlow aggregator based on traffic flows.






23. A BGP feature that overcomes the requirement of a full mesh of iBGP peers inside a single AS by separating the AS into multiple sub-autonomous systems.






24. Dynamic Trunking Protocol.






25. Label Switch Router.






26. Digital Signal Level 0.






27. A 3-tuple consisting of an IP address - port number - and transport layer protocol. TCP connections exist between a pair of sockets.






28. Alarm Indication Signal. With T1s - the practice of sending all binary 1s on the line in reaction to problems - to provide signal transitions and allow recovery of synchronization and framing.






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






30. Neighbor Discovery Protocol.






31. Weighted tail drop.






32. An issue whereby parts of the RF signal take different paths from the source to the destination - which causes direct and reflected signals to reach the receiver at different times - and corresponding bit errors.






33. 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






34. Any occurrence that could change a router's EIGRP topology table - including a received Update or Query - a failed interface - or the loss of a neighbor.






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






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






37. The multicast addresses assigned by IANA.






38. Clear To Send.






39. WRED is a method of congestion avoidance that works by dropping packets before the output queue becomes completely full. WRED can base its dropping behavior on IP Precedence or DSCP values to drop low-priority packets before high-priority packets.






40. A term referring to EIGRP's internal processing logic.






41. A 3-bit field in the first 3 bits of the ToS byte in the IP header - used for QoS marking.






42. A term referring to the processes and bits in the data stream used to manage the Telco TDM hierarchy.






43. In IPv6 - an address used in the Neighbor Discovery (ND) process. The format for these addresses is FF02::1:FF00:0000/104 - and each IPv6 host must join the corresponding group for each of its unicast and anycast addresses.






44. 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.






45. The actual number of packets in a queue at a particular time.






46. A logical concept that represents the path over which frames travel between DTEs. VCs are particularly useful when comparing Frame Relay to leased physical circuits.






47. 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






48. PIM-SM is a method of routing multicast packets that requires some intelligence in the network about the locations of receivers so that multicast traffic is not flooded into areas with no receivers. PIM Sparse Mode gets its name from the assumption t






49. A BGP feature by which a router learns iBGP routes - and then forwards them to other iBGP peers - reducing the required number of iBGP peers while also avoiding routing loops.






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