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 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.






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






3. 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.






4. Layer 2 payload compression.






5. Extensible Authentication Protocol.






6. An NTP mode in which an NTP host does not adjust its clock - but in which it sends NTP messages to clients so that the clients can update their clocks based on the server's clock.






7. With routing protocols - the measurement of favorability that determines which entry will be installed in a routing table if more than one router is advertising that exact network and mask.






8. An IPv6/IPv4 tunneling method that is designed for transporting IPv6 packets within a site where a native IPv6 infrastructures is not available.






9. Rapid Spanning Tree Protocol.






10. Neighbor Discovery Protocol.






11. Peak information rate.






12. The common set of IOS configuration commands that is used with each QoS feature whose name begins with "Class-Based."






13. A term referring generically to a server that performs many AAA functions. It also refers to the software product Cisco Secure Access Control Server.






14. Defined in RFC 1293 - this protocol allows a Frame Relay-attached device to react to a received LMI "PVC up" message by announcing its Layer 3 addresses to the device on the other end of the PVC.






15. In MPLS - the mapping of an IP prefix and a label - which is then advertised to neighbors using LDP.






16. A Cisco-proprietary STP implementation - created many years before IEEE 802.1s and 802.1w - that speeds convergence and allows for one STP instance for each VLAN.






17. Area Border Router. An OSPF router that connects to the backbone area and to one or more non-backbone areas.






18. A bit in the Frame Relay header that - when set to 1 - means that if a device needs to discard frames - it should discard the frames with DE 1 first.






19. With RIP - the regular interval at which updates are sent. Each interface uses an independent timer - defaulting to 30 seconds.






20. A standard (RFC 2131) protocol by which a host can dynamically broadcast a request for a server to assign to it an IP address - along with other configuration settings - including a subnet mask and default gateway IP address. DHCP provides a great de






21. Digital Signal Level 3.






22. Cisco-proprietary STP feature in which a switch port monitors for STP BPDUs of any kind - err-disabling the port upon receipt of any BPDU.






23. Class Selector.






24. 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.






25. A Cisco IOS configuration tool that can be used to match routing updates based on a base network address - a prefix - and a range of possible masks used inside the values defined by the base network address and prefix.






26. Any routing protocol that uses the concept of using the SPF algorithm with an LSDB to compute routes.






27. 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






28. Class-Based Weighted Fair Queuing.






29. A bit in the ATM cell header that - when set to 1 - means that if a device needs to discard frames - it should discard the frames with DE 1 first.






30. In the context of SNMP - the Trap command is sent by an SNMP agent - to a manager - when the agent wants to send unsolicited information to the manager. Trap is not followed by a Response message from the receiving SNMP manager.






31. Differentiated Services Code Point.






32. The process by which neighboring OSPF routers examine their Hello messages and elect the DR. The decision is based on priority (highest) - or RID (highest) if priority is a tie.






33. A conceptual model used by CB Policing when using an excess burst.






34. Superframe






35. An attack by which the attacker initiates many TCP connections to a server - but does not complete the TCP connections - by simply not sending the third segment normally used to establish the connection. The server may consume resources and reject ne






36. An 802.1w RSTP port state in which the port is not the Root Port but is available to become the root port if the current root port goes down.






37. The All OSPF DR Routers multicast IP address - listened for by DR and BDR routers.






38. CDP Control Protocol.






39. Multilink PPP.






40. The original MPLS protocol used to advertise the binding (mapping) information about each particular IP prefix and associated label. It is slightly different from LDP - but functionally equivalent. See also LDP.






41. A Cisco IOS queuing tool that uses MQC configuration commands and reserves a minimum bandwidth for each queue.






42. 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.






43. Copper cable with RJ-45 connectors in which the wire at pin 1 on one end is connected to pin 1 on the other end; the wire at pin 2 is connected to pin 2 on the other end; and so on.






44. Message Digest 5.






45. A Cisco-proprietary protocol used to dynamically negotiate whether the devices on an Ethernet segment want to form a trunk and - if so - which type (ISL or 802.1Q).






46. A standard (RFC 903) protocol by which a LAN-attached host can dynamically broadcast a request for a server to assign it an IP address. See also ARP.






47. Reliable Transport Protocol.






48. Priority queue and priority queuing.






49. A Cisco IOS queuing tool most notable for its scheduler - which always services the high-priority queue over all other queues.






50. The PPP function for fragmenting packets - plus interleaving delay-sensitive later-arriving packets between the fragments of the first packet.
