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. Loss of Frame.






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






3. Pulse code modulation.






4. A wireless LAN that offers connections to the Internet from public places - such as airports - hotels - and coffee shops.






5. Cisco-proprietary STP feature in which a switch port monitors for incoming superior Hellos - and reacts to a superior Hello to prevent any switch connected to that port from becoming root.






6. On a serial cable - the pin lead set by the DCE to imply a working link.






7. Jargon referring to a policer action through which - instead of discarding an out-of-contract packet - the policer marks a different IPP or DSCP value - allowing the packet to continue on its way - but making the packet more likely to be discarded la






8. A type of AS_PATH segment consisting of an unordered list of ASNs consolidated from component subnets of a summary BGP route.






9. An EIGRP message that is used by a router to notify its neighbors when the router is gracefully shutting down.






10. The number of bytes in a queue that are removed per cycle in MDRR. Similar to byte count in the custom queuing (CQ) scheduler.






11. 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.






12. Data-link connection identifier.






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






14. A method used by an IPv6 host to determine its own IP address - without DHCPv6 - by using NDP and the modified EUI-64 address format. See also stateful autoconfiguration.






15. Common Spanning Tree.






16. A BGP message that includes withdrawn routes - path attributes - and NLRI.






17. Designated router.






18. 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.






19. A 1-byte field in the IP header - originally defined by RFC 791 for QoS marking purposes.






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






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






22. An EIGRP message that is used by neighbors to reply to a query. Reply messages require an Ack.






23. The process of running the SPF algorithm against the LSDB - with the result being the determination of the current best route(s) to each subnet.






24. Route Target.






25. Controls the distribution of multicast traffic by checking the TTL values configured on the interfaces. It forwards the multicast packet only on those interfaces whose configured TTL value is less than or equal to the TTL value of the multicast packe






26. The range 232.0.0.0 through 232.255.255.255 that is allocated by IANA for SSM destination addresses and is reserved for use by source-specific applications and protocols.






27. An optional contention-free 802.11 access protocol that requires the access point to poll wireless stations before they are able to send frames. Not commonly implemented.






28. Virtual LAN.






29. Static length subnet masking.






30. A route that is used for forwarding packets when the packet does not match any more specific routes in the IP routing table.






31. A BGP path attribute that lists the next-hop IP address used to reach an NLRI.






32. 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.






33. Differentiated Services.






34. A generic term that refers to the data structure used by a layer in a layered network architecture when sending data.






35. Custom queuing






36. A method of applying a mathematical formula - with input including a private key - the message contents - and sometimes a shared text string - with the resulting digest being included with the message. The sender and the receiver perform the same mat






37. A characterization of a network attack in which packets flow to the attacker - and then out to the true recipient. As a result - the user continues to send data - increasing the chance that the attacker learns more and better information.






38. The term to describe a router that is neither the DR nor the BDR on a subnet that elects a DR and BDR.






39. Policing in which a single rate is metered - and packets are placed into one of two categories (conform or exceed).






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






41. 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.






42. A 16-bit number set with a router config-register command. It is used to set several low-level features related mainly to accessing the router and what the router does when powered on.






43. 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.






44. Often used synonymously with neighbor - but with emphasis on the fact that all required parameters match - allowing routing updates to be exchanged between the routers.






45. A WFQ term referring to its drop logic - which is similar to tail-drop behavior.






46. Quantum value.






47. EIGRP (and IGRP) allows for the use of bandwidth - load - delay - MTU - and link reliability; the K values refer to an integer constant that includes these five possible metric components. Only bandwidth and delay are used by default - to minimize re






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






49. The process of forwarding packets through a router. Also called IP forwarding.






50. Jargon referring to the minimum value to which adaptive shaping will lower the shaping rate.
