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. A type of logic for how a router uses a default route. When a default route exists - and no more specific match is made between the destination of the packet and the routing table - the default route is used.






2. Multiple Spanning Trees.






3. An IPv6/IPv4 tunneling method that allows isolated IPv6 domains to be connected over an IPv4 network.






4. Class-Based Weighted Fair Queuing.






5. Ethernet process by which devices attached to the same cable negotiate their speed and the duplex settings over the cable.






6. Permanent virtual circuit.






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






8. Any other router - sharing a common data link - with which a router exchanges Hellos - and for which the parameters in the Hello pass the parameter-check process.






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






10. VTP pruning.






11. An MPLS LSR that can forward and receive both labeled and unlabeled packets.






12. Extended Superframe.






13. A BGP process by which a router reapplies routing policy configuration (route maps - filters - and the like) based on stored copies of sent and received BGP Updates.






14. Network Address Translation.






15. Web Cache Communication Protocol.






16. Differentiated Services Code Point.






17. The speed at which the access link is clocked. This choice affects the price of the connection and many aspects of traffic shaping and policing - compression - quality of service - and other configuration options.






18. 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.






19. Prefix list.






20. A queuing scheduler concept - much like CQ's scheduler - in which queues are given some service in sequence. This term is often used with queuing in Cisco LAN switches.






21. In the PIM-SM design - the central distribution point to which the multicast traffic is first delivered from the source designated router.






22. The first 48 bits of an IPv6 global address - used for efficient route aggregation.






23. The process of taking the IP - UDP - and RTP headers of a voice or video packet - compressing them - and then uncompressing them on the receiving router.






24. 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






25. Modular QoS CLI.






26. The Frame Relay protocol used between a DCE and DTE to manage the connection. Signaling messages for SVCs - PVC Status messages - and keepalives are all LMI messages.






27. Forwarding Equivalence Class.






28. Operation - Administration - and Maintenance.






29. Controls access to the Internet in public wireless LANs.






30. An integer setting for EIGRP and IGRP. Any FS route whose metric is less than this variance multiplier times the successor's metric is added to the routing table - within the restrictions of the maximum-paths command.






31. Layer 2 payload compression.






32. Classless interdomain routing.






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






34. The process of successive neighboring routers exchanging LSAs such that all routers have an identical LSDB for each area to which they are attached.






35. A serial-line encoding standard that sends alternating positive and negative 3-volt signals for binary 1 - and no signal (0 V) for binary 0.






36. Ethernet feature in which a NIC or Ethernet port can both transmit and receive at the same instant in time. It can be used only when there is no possibility of collisions. Loopback circuitry on NIC cards is disabled to use full duplex.






37. Typically used by protocols that perform flow control (like TCP) - a TCP window is the number of bytes that a sender can send before it must pause and wait for an acknowledgement of some of the yet-unacknowledged data.






38. Data Set Ready.






39. Digital Signal Level 3.






40. Per-Hop Behavior.






41. Cisco-proprietary STP feature in which an access layer switch is configured to be unlikely to become Root or to become a transit switch. Also - convergence upon the loss of the switch's Root Port takes place in a few seconds.






42. A reserved value for the BGP COMMUNITY path attribute that implies that the route should not be advertised to any other peer.






43. A router that should not be used to forward packets between other routers. Other routers will not send Query messages to a stub router.






44. EAP over LAN.






45. 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.






46. Another term for Port Address Translation. See PAT.






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






48. Forward Explicit Congestion Notification.






49. A switch feature in which the switch examines DHCP messages and - for untrusted ports - filters all messages typically sent by servers and inappropriate messages sent by clients. It also builds a DHCP snooping binding table that is used by DAI and IP






50. With some routing protocols - the time period between successive Hello messages.
