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. Generic routing encapsulation.






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






3. Multicast Open Shortest Path First.






4. Customer edge.






5. Congestion window.






6. In the context of SNMP - the Get command is sent by an SNMP manager - to an agent - requesting the value of a single MIB variable identified in the request. The Get request identifies the exact variable whose value the manager wants to retrieve. Intr






7. A method for optimizing the flow of multicast IP packets passing through a LAN switch. The switch using IGMP snooping examines IGMP messages to determine which ports need to receive traffic for each multicast group.






8. A BGP message that includes withdrawn routes - path attributes - and NLRI.






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






10. The 802.1X driver that supplies a username/password prompt to the user and sends/receives the EAPoL messages.






11. The process of changing the electrical characteristics on a transmission medium - based on defined rules - to represent data.






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






13. 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.






14. Multiple Spanning Trees.






15. The Cisco IOS Router IP Traffic Export feature - intended for intrusion detection - exports IP traffic that has signs of an attack - such as duplicate IP packets simultaneously received on two or more of a router's interfaces.






16. Used to reserve network resources for a flow as it traverses the network. A device that creates an RSVP reservation guarantees that it can provide the bandwidth - latency - or other resources that are requested by RSVP.






17. A calculated TCP variable - used along with the TCP CWND variable - to dictate a TCP sender's behavior when it recognizes packet loss. As CWND grows after packet loss - the TCP sender increases CWND based on Slow Start rules - until CWND grows to be






18. A type of spread spectrum that spreads RF signals over the frequency spectrum by representing each data bit by a longer code. 802.11b specifies the use of DSSS.






19. A method of Link Fragmentation and Interleaving (LFI) over interfaces that natively use Frame Relay encapsulation. The routers first build MLP-style PPP headers - which are then encapsulated inside a Frame Relay header. The PPP headers are then used






20. 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.






21. A designated router that is directly connected with a source of the multicast group.






22. A route that is used for forwarding packets when the packet does not match any more specific routes in the IP routing table.






23. The low-order 4 bits of the configuration register. These bits direct a router to load either ROMMON software (boot field 0x0) - RXBOOT software (boot field 0x1) - or a full-function IOS image.






24. A DiffServ PHB that defines eight values that provide backward compatibility with IP Precedence.






25. Tag Distribution Protocol.






26. A standards-based way of helping routers find Rendezvous Points (RP). RPs notify BSRs of the groups they handle. BSRs in turn flood the group-to-RP mappings throughout the network. Each router individually determines which RP to use for a particular






27. Retransmission Timeout.






28. Local Management Interface.






29. A 3-bit field in an 802.1Q header used for marking frames.






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






31. Jargon referring to the minimum value to which adaptive shaping will lower the shaping rate.






32. 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.






33. The operating mode of shaped round-robin that provides behavior like CBWFQ with bandwidth allocated between different traffic classes by a relative amount rather than absolute percentage of the available bandwidth.






34. Weighted fair queuing.






35. Carrier sense multiple access with collision detection. A media-access mechanism where devices ready to transmit data first check the channel for a carrier. If no carrier is sensed for a specific period of time - a device can transmit. If two devices






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






37. Context-Based Access Control.






38. A characterization of a BGP path attribute in which BGP implementations are not required to support the attribute (optional) - and for which if a router receives a route with such an attribute - the router should remove the attribute before advertisi






39. An Internet standard authentication protocol that uses clear-text passwords and a two-way handshake to perform authentication over a PPP link.






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






41. Controls the distribution of multicast traffic for the private multicast address range 239.0.0.0 to 239.255.255.255 by configuring a filter and applying it on the interfaces.






42. The rate at which a shaper limits the bits exiting the shaper.






43. Prefix list.






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






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






46. The process of successive neighboring routers exchanging LSAs such that all routers have an identical LSDB for each area to which they are attached.






47. For some encoding schemes - consecutive signals must use opposite polarity in an effort to reduce DC current. A BPV occurs when consecutive signals are of the same polarity.






48. The mandatory contention-based 802.11 access protocol that is also referred to as CSMA/CA.






49. On a serial cable - the pin lead set by the DCE to tell the DTE that the DTE is allowed send data.






50. With Spanning Tree Protocol - the single port on each LAN segment from which the best Hello BPDU is forwarded.
