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 password required by the enable command. Also - this term may specifically refer to the password defined by the enable password command.






2. An EIGRP message that informs neighbors about routing information. Update messages require an Ack.






3. In two-rate policing - the second and higher rate defined to the policer.






4. Superframe






5. A table inside a router that holds the path attributes and NLRI known by the BGP implementation on that router.






6. A packet-scheduling algorithm used in Cisco switches that provides similar behavior to CBWFQ in shared mode and polices in shaped mode.






7. EIGRP jargon meaning that EIGRP has placed a route into active status.






8. 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.






9. Inverse ARP.






10. A network/subnet to which only one OSPF router is connected.






11. Common Spanning Tree.






12. A standard (RFC 3768) feature by which multiple routers can provide interface IP address redundancy so that hosts using the shared - virtual IP address as their default gateway can still reach the rest of a network even if one or more routers fail.






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






14. 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.






15. A mechanism used by TCP senders to limit the dynamic window for a TCP connection - to reduce the sending rate when packet loss occurs. The sender considers both the advertised window size and CWND - using the smaller of the two.






16. Layer 2 payload compression.






17. A Cisco IOS queuing tool most notable for its automatic classification of packets into separate per-flow queues.






18. Label Forwarding Information Base.






19. 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.






20. A PPP feature used to load balance multiple parallel links at Layer 2 by fragmenting frames - sending one frame over each of the links in the bundle - and reassembling them at the receiving end of the link.






21. The portions of PPP focused on features that are related to specific Layer 3 protocols.






22. Penultimate hop popping.






23. The All OSPF Routers multicast IP address - listened for by all OSPF routers.






24. Context-Based Access Control.






25. Aka network layer reachability information.






26. Neighbor Advertisement.






27. A contiguous group of data links that share the same OSPF area number.






28. An MPLS application that allows the MPLS network to connect to multiple different IP networks - with overlapping IP addresses - and provide IP connectivity to those multiple networks.






29. Prefix list.






30. In BGP - a feature in which BGP routes cannot be considered to be a best route to reach an NLRI unless that same prefix exists in the router's IP routing table as learned via some IGP.






31. A name used for DS3 lines inside the European TDM hierarchy.






32. A state for a route in an EIGRP topology table that indicates that the router believes that the route is stable - and it is not currently looking for any new routes to that subnet.






33. A term used with Cisco LAN switches - referring to a DSCP value used when making QoS decisions about a frame. This value may not be the actual DSCP value in the IP header encapsulated inside the frame.






34. Rapid Spanning Tree Protocol.






35. An Internet standard (RFC 1305) that defines the messages and modes used for IP hosts to synchronize their time-of-day clocks.






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






37. Cisco Express Forwarding.






38. In IPv6 - the Neighbor Discovery message used by an IPv6 node to send information about itself to its neighbors.






39. A specification for the 64-bit interface ID in an IPv6 address - composed of the first half of a MAC address - hex FFFE - and the last half of the MAC.






40. An IPv6 address type that is used by a number of hosts in a network that are providing the same service. Hosts accessing the service are routed to the nearest host in an anycast environment based on routing protocol metrics.






41. When subnetting a class A - B - or C address - the subnet for which all subnet bits are binary 0.






42. Enhances RP redundancy by providing a method for RPs to exchange multicast source information - even between multicast domains.






43. 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.






44. Network Control Protocol.






45. Data terminal equipment.






46. The structure inside telcos' original digital circuit build-out in the mid-1900s - based upon using TDM to combine and disperse smaller DS levels into larger levels - and vice versa.






47. Each 802.11 station periodically sends a probe request frame on each RF channel and monitors probe response frames that all access points within range send back. Stations use the signal strength of the probe response frames to determine which access






48. A message sent by a multicast router - by default every 125 seconds - on each of its LAN interfaces to determine whether any host wants to receive multicast traffic for any group.






49. Multilink PPP.






50. A Cisco IOS configuration tool for RIP and EIGRP for which the list matches routes in routing updates - and adds a defined value to the sent or received metric for the routes. The value added to the metric is the offset.
