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. Defined in IEEE 802.1AD - defines a messaging protocol used to negotiate the dynamic creation of PortChannels (EtherChannels) and to choose which ports can be placed into an EtherChannel.






2. An FRF standard for LFI for data (FRF.3) VCs.






3. A routing protocol feature by which the routing update includes the entire set of routes - even if some or all of the routes are unchanged.






4. Another name for Superframe.






5. Each 802.11 station passively monitors each RF channel for a specific amount of time and listens for beacons. Stations use the signal strengths of found beacons to determine the access point or ad hoc network with which to attempt association.






6. Distance Vector Multicast Routing Protocol.






7. A method for how a TCP sender grows its calculated CWND variable - thereby growing the allowed window for the connection. Congestion Avoidance grows CWND linearly.






8. A definition that determines the data structure and information implied by a particular LSA.






9. A component of the IOS IP SLA feature. An IP SLA responder is a router configured to respond to a particular IP SLA message initiated by another router - allowing the routers to work together to provide performance information including UDP jitter an






10. Virtual LAN.






11. An NTP mode in which two or more NTP servers mutually synchronize their clocks.






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






13. The signal strength of the RF signal at the output of the radio card or access point transmitter - before being fed into the antenna. Measured in milliwatts - watts - or dBm.






14. 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.






15. Time-division multiplexing.






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






17. Network Address Translation-Protocol Translation.






18. Cisco-proprietary STP feature in which a switch port - known to not have a bridge or switch attached to it - transitions from disabled to forwarding state without using any intermediate states.






19. 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






20. Receivers subscribe to an (S -G) channel when they request to join a multicast group. That is - they specify the unicast IP address of their multicast source and the group multicast address. SSM is typically used in very large multicast deployments s






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






22. A Cisco-proprietary STP implementation - created many years before IEEE 802.1s and 802.1w - that speeds convergence and allows for one STP instance for each VLAN.






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






24. Forward Explicit Congestion Notification.






25. Reported distance or Route Distinguisher.






26. Version 6 of the IP protocol - which uses 128-bit IP addresses.






27. A queuing tool's logic by which it selects the next packet to dequeue from its many queues.






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. Request-to-send/clear-to-send.






30. The number of bytes in a queue that are removed per cycle in MDRR. Similar to byte count in the custom queuing (CQ) scheduler.






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






32. A method of providing dynamically configured spoke-to-spoke VPN connectivity in a hub-and-spoke network that significantly reduces configuration required on the spoke routers compared to traditional IPsec VPN environments.






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






34. Cisco IOS IP Service Level Agent feature. Provides for router-generated information useful for verifying network performance on a scheduled basis - and the associated reporting functions.






35. A reserved value for the BGP COMMUNITY path attribute that implies that the route should not be advertised to any other peer.






36. An enhanced version of T1 framing - as compared with the earlier Superframe (D4) standard.






37. The 802.1X function implemented by a switch - in which the switch translates between EAPoL and RADIUS messages in both directions - and enables/disables ports based on the success/failure of authentication.






38. 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.






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






40. An EIGRP router's reaction to an input event - leading to the use of a feasible successor or going active on a route.






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






42. An NTP client that assumes that a server will send NTP broadcasts - removing the requirement for the client to have the NTP server's IP address preconfigured.






43. The range 239.0.0.0 through 239.255.255.255 that IANA has assigned for use in private multicast domains.






44. A Cisco-proprietary messaging protocol implemented in WAN switches that can be used to signal network status - including congestion - independent of end-user frames and cells.






45. Cell Loss Priority.






46. Cisco IOS Embedded Event Manager - a feature that monitors events on a router and reports their results. Principally intended to increase availability - EEM provides flexible - granular detection and alerting functions.






47. Data Set Ready.






48. The same thing as TCP code bits. See TCP code bits.






49. CDP Control Protocol.






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