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. Link-state database.






2. A BGP neighbor state in which the BGP neighbors have stabilized and can exchange routing information using BGP Update messages.






3. Per-Hop Behavior.






4. A group of devices on one or more LANs that are configured (using management software) so that they can communicate as if they were attached to the same wire - when - in fact - they are located on a number of different LAN segments. Because VLANs are






5. Label Forwarding Information Base.






6. Distance Vector Multicast Routing Protocol.






7. 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






8. A set of packets in an MPLS network for which the MPLS network will apply the exact same forwarding behavior.






9. Jargon used to refer to the first of two buckets in the dual token bucket model; its size is Bc.






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






11. Weighted fair queuing.






12. An STP timer that dictates the interval at which the Root switch generates and sends Hello BPDUs.






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






14. A process on a computing device that accepts SNMP requests - responds with SNMP-structured MIB data - and initiates unsolicited Trap messages back to an SNMP management station.






15. Label Switch Router.






16. The protocol used by content engines to manage traffic flow between routers configured for WCCP and between content engines. WCCP takes advantage of the fact that many web pages (and other content) are regularly accessed by users in a given network.






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






18. The OSPF data structure that describes topology information.






19. A term used with WFQ for the number assigned to a packet as it is enqueued into a WFQ queue. WFQ schedules the currently lowest FT packet next.






20. An optimized Layer 3 forwarding path through a router or switch. CEF optimizes routing table lookup by creating a special - easily searched tree structure based on the contents of the IP routing table. The forwarding information is called the Forward






21. On a serial cable - the pin lead set by the DTE to tell the DCE that the DTE wants to send data.






22. Defined in IEEE 802.1s - a specification for multiple STP instances when using 802.1Q trunks






23. When subnetting a class A - B - or C address - the subnet for which all subnet bits are binary 1.






24. A BGP path attribute that is communicated throughout a single AS to signify which route of multiple possible routes is the best route to be taken when leaving that AS. A larger value is considered to be better.






25. In IPv6 - a Router Advertisement message used by an IPv6 router to send information about itself to nodes and other routers connected to that router.






26. 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.






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






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






29. 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.






30. 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.






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






32. A convention for IP addresses in which class A - B - and C default network prefixes (of 8 - 16 - and 24 bits - respectively) are ignored.






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






34. Database Description.






35. A message sent by each host - either in response to a router Query or on its own - to all multicast groups for which it would like to receive multicast traffic.






36. Prefix list.






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






38. Defined in IEEE 802.1d - a protocol used on LAN bridges and switches to dynamically define a logical network topology that allows all devices to be reached - but prevents the formation of loops.






39. Link-state advertisement.






40. Part of the Cisco IOS Firewall feature set - CBAC inspects traffic using information in the higher-layer protocols being carried to decide whether to open the firewall to specific inbound traffic. CBAC supports both UDP and TCP and multiple higher-la






41. With EIGRP - the metric value for the lowest-metric route to a particular subnet.






42. Wi-Fi Protected Access. A security standard that includes both TKIP and AES and was ratified by the Wi-Fi Alliance.






43. 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






44. Receiver's advertised window.






45. An 802.1d STP port state in which the port has been administratively disabled.






46. A characterization of a BGP path attribute in which all BGP implementations must support and understand the attribute (well known) - and all BGP Updates must include the attribute (mandatory).






47. Aka Rapid Per-VLAN Spanning Tree Plus.






48. A switch feature that examines incoming frames - comparing the source IP and MAC addresses to the DHCP snooping binding database - filtering frames whose addresses are not listed in the database for the incoming interface.






49. A BGP path attribute that allows routers in one AS to set a value and advertise it into a neighboring AS - impacting the decision process in that neighboring AS. A smaller value is considered better. Also called the BGP metric.






50. In MQC and CB Policing - a configuration style by which - for one category of packets (conform - exceed - or violate) - more than one marking action is defined for a single category. For example - marking DSCP and DE.
