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. 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.






2. Diffusing Update Algorithm.






3. 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






4. A state variable kept by a router for each known neighbor or potential neighbor.






5. The condition in which a route has been in an EIGRP active state for longer than the router's Active timer.






6. Exterior Gateway Protocol.






7. A tunneling protocol that can be used to encapsulate many different protocol types - including IPv4 - IPv6 - IPsec - and others - to transport them across a network.






8. An OSPF external route for which internal OSPF cost is added to the cost of the route as it was redistributed into OSPF.






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






10. 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.






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






12. 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.






13. In MPLS - a term used to define a label that an LSR allocates and then advertises to neighboring routers. The label is considered "local" on the router that allocates and advertises the label.






14. 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.






15. A set of DiffServ PHBs that defines 12 DSCP values - with four queuing classes and three drop probabilities within each queuing class.






16. Designated router.






17. 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.






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






19. Maximum transmission unit.






20. On a serial cable - the pin lead set by the DCE to imply that the DCE is ready to signal using pin leads






21. A time value that each wireless station must set based on the duration value found in every 802.11 frame. The time value counts down and must be equal to zero before a station is allowed to access the wireless medium. The result is a collision-avoida






22. The portion of PPP focused on features that are unrelated to any specific Layer 3 protocol.






23. Data communications equipment.






24. The feature in a Cisco IOS device by which a terminal session's previously typed commands are remembered - allowing the user to recall the old commands to the command line through a simple key sequence (for example - the up-arrow key).






25. Wired Equivalent Privacy.






26. Bootstrap Router.






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






28. An 802.1d STP port state in which the port sends and receives frames.






29. The IP address to which Label Distribution Protocol (LDP) sends LDP Hellos. Also used in IP multicast to send packets to all multicast routers.






30. A BGP feature that defines the IP TTL field value in packets sent between two eBGP peers. This feature is required when using IP addresses other than the interface IP address on the link between peers.






31. 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






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






33. A Cisco IOS configuration tool for routing protocols by which routing updates may be filtered.






34. Message Digest 5.






35. A local Cisco-proprietary BGP setting that is not advertised to any peers. A larger value is considered to be better.






36. An MQC-based feature of IOS that is used to classify and mark packets for QoS purposes.






37. Loss of Frame.






38. A term referring to EIGRP's internal processing logic.






39. A single instance of STP that is applied to multiple VLANs - typically when using the 802.1Q trunking standard.






40. The original standardized set of generic SNMP MIB variables - defined in RFC 1158.






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






42. IP Control Protocol.






43. 16 bits between the interface ID and global routing prefix in an IPv6 global address - used for subnet assignment inside an enterprise.






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






45. From one multicast router's perspective - the upstream router is another router that has just forwarded a multicast packet to that router.






46. Border Gateway Protocol.






47. 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.






48. RFC 1918-defined IPv4 network numbers that are not assigned as public IP address ranges - and are not routable on the Internet. Intended for use inside enterprise networks.






49. 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. The destination address on the Report is 224.0.0.22 - and a host can specify the source a






50. Boot Protocol. A standard (RFC 951) protocol by which a LAN-attached host can dynamically broadcast a request for a server to assign it an IP address - along with other configuration settings - including a subnet mask and default gateway IP address.
