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






2. Route Target.






3. A characteristic of OSPF interfaces that determines whether a DR election is attempted - whether or not neighbors must be statically configured - and the default Hello and Dead timer settings.






4. Records client authentication and roaming events - which are sent to the CiscoWorks Wireless LAN Solution Engine (WLSE) to monitor client associations to specific access points.






5. An MPLS term referring to the first of several labels when an MPLS-forwarded packet has multiple labels (a label stack).






6. A TCP variable that defines the largest number of bytes allowed in a TCP segment's Data field. The calculation does not include the TCP header. With a typical IP MTU of 1500 bytes - the resulting default MSS would be 1460. TCP hosts must support an M






7. A multicast routing protocol that forwards the multicast traffic only when requested by a downstream router.






8. A Cisco-proprietary LMI protocol - implemented in Cisco WAN switches and routers - through which the switch can inform the router about parameters for each VC - including CIR - Bc - and Be.






9. With EIGRP - a router sharing the same primary subnet - with which Hellos are exchanged - parameters match - and with which routes can be exchanged.






10. In an IOS confederation configuration - the actual ASN as seen by eBGP peers.






11. Protocol Independent Multicast dense-mode routing protocol.






12. 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.






13. Smoothed Round-Trip Time.






14. Designated router.






15. Weighted fair queuing.






16. 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.






17. Message Digest 5.






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






19. In PIM-SM - the path of the group traffic that flows from the RP to the routers that need the traffic. It is also called the root-path tree (RPT) - because it is rooted at the RP.






20. The PPP function for fragmenting packets - plus interleaving delay-sensitive later-arriving packets between the fragments of the first packet.






21. IP Control Protocol.






22. The SNMP specifications - standardized in RFCs - defining the rules by which SNMP MIB variables should be defined.






23. A strategy for subnetting a classful network for which all masks/prefixes are the same value for all subnets of that one classful network.






24. Link-State Refresh. A timer that determines how often the originating router should reflood an LSA - even if no changes have occurred to the LSA.






25. When a PIM-SM router switches from RPT to SPT - it sends a PIM-SM Prune message for the source and the group with the RP bit set to its upstream router on the shared tree. RFC 2362 uses the notation PIM-SM (S - G) RP-bit Prune for this message.






26. With EIGRP - for a particular route - the case in which the RD is lower than the FD.






27. On a multiaccess network - when a PIM-DM or PIM-SM router receives a Prune message - it starts a 3-second timer. If it receives a Join message on the multiaccess network from another router before the timer expires - it considers the message as an ov






28. Local Management Interface.






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






30. A term used with Cisco LAN switches - referring to a queue treated with strict-priority scheduling.






31. Cisco-proprietary STP feature in which a switch port monitors for incoming superior Hellos - and reacts to a superior Hello to prevent any switch connected to that port from becoming root.






32. A VC that is set up dynamically when needed. An SVC can be equated to a dial-on-demand connection in concept.






33. The encapsulation of EAP messages directly inside LAN frames. This encapsulation is used between the supplicant and the authenticator.






34. Defines a particular behavior for FTP regarding the establishment of data TCP connections. In active mode - the FTP client uses the FTP PORT command - over the FTP control connection - to tell the FTP server the port on which the client should be lis






35. Measured Round-Trip Time.






36. An OSPF area into which external (type 5) LSAs are not introduced by its ABRs; instead - the ABRs originate and inject default routes into the area.






37. 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.






38. Enhanced Local Management Interface.






39. A Cisco switch feature that allows separation of ports as if they were in separate VLANs - while allowing the use of a single IP subnet for all ports.






40. In the PIM-SM design - the process by which a source DR - after it starts to receive the group traffic - encapsulates the multicast packets in the unicast packets and sends them to the RP.






41. The IEEE standardized protocol for VLAN trunking.






42. An exterior routing protocol designed to exchange prefix information between different autonomous systems. The information includes a rich set of characteristics called path attributes - which in turn allows for great flexibility regarding routing ch






43. Common Spanning Tree.






44. Exterior Gateway Protocol.






45. Flush timer.






46. IP multicast address range from 224.0.0.0 through 239.255.255.255.






47. Congestion window.






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






49. In the context of SNMP - the GetNext command is sent by an SNMP manager - to an agent - requesting the value of a single MIB variable. The GetNext request identifies a variable for which the manager wants the variable name and value of the next MIB l






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