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 BGP router in an AS that uses route reflectors - but that is not aided by any RR server.






2. An intrusion detection system that safeguards the wireless LAN from malicious and unauthorized access.






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






4. 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.






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






6. When a wireless station connects to an access point - the access point assigns an association ID (AID) to the station. Various protocols - such as power-save mode - make use of the association ID.






7. Weighted tail drop.






8. With a routing update - or routing table entry - the portion of a route that defines the next router to which a packet should be sent to reach the destination subnet. With routing protocols - the Next Hop field may define a router other than the rout






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






10. Gateway Load Balancing Protocol.






11. Expedited Forwarding.






12. A basic form of traffic shaping that is applied to an interface or subinterface. By default - it shapes all traffic leaving the interface - but can be modified by using an access control list. The access list controls only what traffic is shaped; GTS






13. Slow Start Threshold.






14. Excess Burst.






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






16. Removing unwanted VLANs from a Layer 2 path.






17. A bit in the LAPF Frame Relay header that - when set to 1 - implies that the frame has experienced congestion.






18. 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.






19. Bipolar 8 Zero Substitution. A serial-line encoding standard that substitutes Bipolar Violations in a string of eight binary 0s to provide enough signal transitions to maintain synchronization.






20. A 48-bit address that is calculated from a Layer 3 multicast address by using 0x0100.5E as the multicast vendor code (OUI) for the first 24 bits - always binary 0 for the 25th bit - and copying the last 23 bits of the Layer 3 multicast address.






21. An architecture and set of documents that defines Cisco's best recommendations for how to secure a network.






22. An MPLS term describing designs in which one or more MPLS customer sites can be reached from multiple other VPNs.






23. Maximum Segment Size.






24. Backward Explicit Congestion Notification.






25. 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.






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






27. An interface on a Cisco IOS-based switch that is treated as if it were an interface on a switch.






28. 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.






29. The process of taking the IP and TCP headers of a packet - compressing them - and then uncompressing them on the receiving router.






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. The two computers use a protocol with which to communicate with the same layer on another computer. The protocol defined by each layer uses a header that is transmitted between the computers to communicate what each computer wants to do.






32. Customer edge.






33. Class-Based Weighted Fair Queuing.






34. Protocol data unit.






35. A conceptual model used by shapers and policers to represent their internal logic.






36. A route that is created to represent one or more smaller component routes - typically in an effort to reduce the size of routing and topology tables.






37. The process of combining multiple synchronized input signals over a single medium by giving each signal its own time slot - and then breaking out those signals.






38. A Cisco-proprietary protocol that defines how to perform authentication between an authenticator (for example - a router) and an authentication server that holds a list of usernames and passwords.






39. Neighbor Discovery Protocol.






40. A term referring to the MQC policy-map command and its related subcommands - which are used to apply QoS actions to classes of packets.






41. A NAT term describing an IP address representing a host that resides outside the enterprise network - with the address being used in packets outside the enterprise network.






42. A Cisco 12000 series router feature that combines the key features of LLQ and CQ to provide similar congestion-management features.






43. IP Control Protocol.






44. A security standard that includes both TKIP and AES and was ratified by the Wi-Fi Alliance.






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






46. Dynamic Trunking Protocol.






47. Autonomous System Boundary Router. An OSPF router that redistributes routes from some other source into OSPF.






48. Reported distance or Route Distinguisher.






49. Smoothed Round-Trip Time.






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