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. Aka receiver's advertised window.






2. A name used for DS3 lines inside the North American TDM hierarchy.






3. A well-known discretionary BGP path attribute that flags a route as being a summary route.






4. A Cisco-proprietary protocol - used by LAN switches to communicate VLAN configuration.






5. A field within a route entry in a routing update - used to associate a generic number with the route. It is used when passing routes between routing protocols - allowing an intermediate routing protocol to pass information about a route that is not n






6. Gateway Load Balancing Protocol.






7. Measured Round-Trip Time.






8. An MPLS VPN term referring to any LSR that connects to customers to support the forwarding of unlabeled packets - as well as connecting to the MPLS network to support labeled packets - thereby making the LSR be on the edge between the provider and th






9. Retransmission Timeout.






10. 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.






11. A 3-bit field in an MPLS header used for marking frames.






12. Static length subnet masking.






13. Variable name for the time interval used by shapers and by CAR.






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






15. A mapping between each DSCP value and a WRED threshold - often used in Cisco LAN switches when performing WRED.






16. Version 4 of the IP protocol - which is the generally deployed version worldwide (at publication) - and uses 32-bit IP addresses.






17. With EIGRP - the metric value for the lowest-metric route to a particular subnet.






18. Link-state advertisement.






19. In the context of SNMP - the Response command is sent by an SNMP agent - back to a manager - in response to any of the three types of Get requests - or in response to a Set request. It is also used by a manager in response to a received Inform comman






20. A technology that sends a high-speed data stream over multiple subcarriers simultaneously. It is highly immune to multipath interference. 802.11a and 802.11g specify the use of OFDM.






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






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






23. The Cisco IOS feature by which special short key sequences can be used to move the cursor inside the current command line to more easily change a command.






24. An SPF calculation for which a router does not need to run SPF for any LSAs inside its area - but instead runs a very simple algorithm for changes to LSAs outside its own area.






25. Instead of advertising all routes out a particular interface - the routing protocol omits the routes whose outgoing interface field matches the interface out which the update would be sent.






26. A term referring to the MQC service-policy command - which is used to enable a policy map on an interface.






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






28. The multicast IP address 224.0.0.6 - listened for by DR and BDR routers.






29. A set of DiffServ PHBs that defines 12 DSCP values - with four queuing classes and three drop probabilities within each queuing class.






30. Excess Burst.






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






32. An NTP client that assumes that a server will send NTP broadcasts - removing the requirement for the client to have the NTP server's IP address preconfigured.






33. Sending a message from a single source or multiple sources to selected multiple destinations across a Layer 3 network in one data stream.






34. Another name for Superframe.






35. 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.






36. PIM-SM is a method of routing multicast packets that requires some intelligence in the network about the locations of receivers so that multicast traffic is not flooded into areas with no receivers. PIM Sparse Mode gets its name from the assumption t






37. Extended Superframe.






38. A multicast routing protocol whose default action is to flood multicast packets throughout a network.






39. A term used with WFQ for the number assigned to a packet as it is enqueued into a WFQ. WFQ schedules the currently lowest SN packet next.






40. A single address in each subnet for which packets sent to this address will be broadcast to all hosts in the subnet. It is the highest numeric value in the range of IP addresses implied by a subnet number and prefix/mask.






41. A type of OSPF stub area for which neither external (type 5) LSAs are introduced - nor type 3 summary LSAs; instead - the ABRs originate and inject default routes into the area. External routes cannot be injected into a totally stubby area.






42. A CBWFQ and LLQ term referring to the bandwidth on an interface that is neither reserved nor allocated via a priority command.






43. Defined in RFC 2091 - the extensions define how RIP may send a full update once - and then send updates only when routes change - when an update is requested - or when a RIP interface changes state from down to up.






44. An IPv6 address format used for publicly registered IPv6 addresses.






45. Tag Distribution Protocol.






46. A 3-bit field in the first 3 bits of the ToS byte in the IP header - used for QoS marking.






47. Network Address Translation-Protocol Translation.






48. Source-specific multicast.






49. Route Target.






50. Multilink PPP.
