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. 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.






2. 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.






3. Multicast addresses that are not assigned by IANA.






4. Data Carrier Detect.






5. An alternative software loaded into a Cisco router - used for basic IP connectivity; most useful when Flash memory is broken and you need IP connectivity to copy a new IOS image into Flash memory.






6. 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






7. Uses Modular QoS CLI to control the amount and type of traffic handled by the router or switch control plane. Class maps identify traffic types - and then a service policy applied to the device control plane sets actions for each type of traffic.






8. A commonly used name for Multi-VRF CE.






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






10. The ASN assigned to a confederation sub-AS.






11. A 3-bit field in an ISL header used for marking frames. Also - used generically to refer to either the ISL CoS field or the 802.1Q User Priority field.






12. Password Authentication Protocol.






13. Autonomous System Boundary Router. An OSPF router that redistributes routes from some other source into OSPF.






14. In IP routing - a term referring to the process of forwarding packets through a router.






15. In shaping and policing - commonly used to refer to the shaping or policing rate. For WAN services - a common reference to the bit rate defined in the WAN service business contract for each VC.






16. A term relating to Cisco LAN switch tail-drop logic - in which multiple tail-drop thresholds may be assigned based on CoS or DSCP - resulting in some frames being discarded more aggressively than others.






17. A type of OSPF packet - used to communicate LSAs to another router.






18. In 802.1X - the computer that stores usernames/passwords and verifies that the correct values were submitted before authenticating the user.






19. Enables a wireless client to securely roam between access points in the same subnet or between subnets with access point handoff times within 50 ms.






20. In wireless LANs - a mechanism that counters issues related to RF interference by dividing a larger 802.11 data frame into smaller frames that are sent independently to the destination. See also LFI.






21. Network Control Protocol.






22. The second byte of the IP header - formerly known as the ToS byte and redefined by DiffServ.






23. A configuration tool in Cisco IOS that allows basic programming logic to be applied to a set of items. Often used for decisions about what routes to redistribute - and for setting particular characteristics of those routes






24. Allows the router to act as an inline IPS - doing deep packet inspection.






25. Spanning Tree Protocol.






26. 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






27. Backup designated router.






28. Common Spanning Tree.






29. Backward Explicit Congestion Notification.






30. 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.






31. An effort to reduce the query scope with EIGRP - using route summarization or EIGRP stub routers.






32. A workstation or server configured to collect and present RMON data for reporting purposes.






33. Static length subnet masking.






34. Jargon referring to any queue that receives priority service - often used for queues in an LLQ configuration that have the priority command configured.






35. A multicast routing protocol whose default action is to flood multicast packets throughout a network.






36. A name used for DS1 lines inside the North American TDM hierarchy.






37. 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.






38. A router that is not an ABR or ASBR in that all of its interfaces connect to only a single OSPF area.






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






40. The RFC-standard MPLS protocol used to advertise the binding (mapping) information about each particular IP prefix and associated label. See also TDP.






41. Loss of Signal. A T1 alarm state that occurs when the receiver has not received any pulses of either polarity for a defined time period.






42. The practice of defining boundaries that determine how far multicast traffic will travel in your network.






43. An optional transitive BGP path attribute that - for a summary route - lists the BGP RID and ASN of the router that created the summary.






44. Not-so-stubby area.






45. The single port on each nonroot switch upon which the best Hello BPDU is received.






46. A CBWFQ and LLQ term referring to the bandwidth on an interface that is neither reserved nor allocated via a priority command.






47. A BGP router in an AS that uses route reflectors - but that is not aided by any RR server.






48. A mapping between each DSCP value and a WRED threshold - often used in Cisco LAN switches when performing WRED.






49. Frame Relay Forum.






50. A Cisco IOS interface setting - as a percentage between 1 and 99 - that defines how much of the interface's bandwidth setting may be allocated by a queuing tool. The default value is 75 percent.
