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 Cisco IOS queuing tool most notable for its automatic classification of packets into separate per-flow queues.






2. 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.






3. Used to reserve network resources for a flow as it traverses the network. A device that creates an RSVP reservation guarantees that it can provide the bandwidth - latency - or other resources that are requested by RSVP.






4. The encapsulation of EAP messages directly inside LAN frames. This encapsulation is used between the supplicant and the authenticator.






5. In MPLS - a term used to define a label that an LSR learned from a neighboring LSR.






6. Low-latency queuing.






7. AutoQoS is a macro that creates and applies quality of service configurations based on Cisco best-practice recommendations.






8. A method of collecting traffic received on a switch port or a VLAN and sending it to specific destination ports on the same switch.






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






10. A method of providing dynamically configured spoke-to-spoke VPN connectivity in a hub-and-spoke network that significantly reduces configuration required on the spoke routers compared to traditional IPsec VPN environments.






11. Maximum Response Time.






12. Calculated measurement based on the actual queue depth and the previous average. Designed to allow WRED to adjust slowly to rapid changes of the actual queue depth.






13. Dynamic Multipoint VPN.






14. Jargon referring to any queue that receives priority service - often used for queues in an LLQ configuration that have the priority command configured.






15. An exterior routing protocol designed to exchange prefix information between different autonomous systems. The information includes a rich set of characteristics called path attributes - which in turn allows for great flexibility regarding routing ch






16. Border Gateway Protocol.






17. Dynamic ARP Inspection.






18. Ethernet MAC address that represents all devices on the LAN.






19. In an IOS confederation configuration - the actual ASN as seen by eBGP peers.






20. A T1 alarm state that occurs when a device has detected a local LOF/LOS/AIS condition. The device in Red alarm state then sends a Yellow alarm signal.






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






22. In BGP - a configuration construct in which multiple neighbors' parameters can be configured as a group - thereby reducing the length of the configuration. Additionally - BGP performs routing policy logic against only one set of Updates for the entir






23. A communication protocol between hosts and a multicast router by which routers learn of which multicast groups' packets need to be forwarded onto a LAN.






24. The process of taking a PDU from some other source and placing a header in front of the original PDU - and possibly a trailer behind it.






25. With EIGRP - a purposefully slowly changing measurement of round-trip time between neighbors - from which the EIGRP RTO is calculated.






26. Finish time.






27. 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.






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






29. Internet Group Management Protocol.






30. Another name for 802.1Q-in-Q. See 802.1Q-in-Q.






31. Data terminal equipment.






32. The MD5-encoded password defined by the enable secret command.






33. An enhanced version of WEP that is part of the 802.11i standard and has an automatic key-update mechanism that makes it much more secure than WEP. TKIP is not as strong as AES in terms of data protection.






34. A Cisco router feature in which the router works to prevent SYN attacks either by monitoring TCP connections flowing through the router - or by actively terminating TCP connection until the TCP connection is established and then knitting the client-s






35. Backward Explicit Congestion Notification.






36. Neighbor Advertisement.






37. An alternative software loaded into a Cisco router - used for low-level debugging and for password recovery.






38. 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.






39. Inside telcos' original TDM hierarchy - the smallest unit of transmission at 64 kbps.






40. Reverse ARP.






41. A switch feature that limits the number of allowed MAC addresses on a port - with optional limits based on the actual values of the MAC addresses.






42. An early standard from AT&T for encoding analog voice as a digital signal for transmission over a TDM network. PCM requires 64 kbps - and is the basis for the DS0 speed.






43. Regeneration of the Layer 2 encapsulation removed from frames forwarded in a SPAN session.






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






45. A strategy for subnetting a classful network for which all masks/prefixes are the same value for all subnets of that one classful network.






46. A characterization of a BGP path attribute in which BGP implementations are not required to support the attribute (optional) - and for which if a router receives a route with such an attribute - the router should remove the attribute before advertisi






47. A Cisco IOS interface setting - as a percentage between 1 and 99 - that defines how much of the interface's bandwidth setting may be allocated by a queuing tool. The default value is 75 percent.






48. A name used for DS1 lines inside the North American TDM hierarchy.






49. A T1 alarm state that occurs when a device receives a Yellow Alarm signal. This typically means that the device on the other end of the line is in a Red Alarm state.






50. A network/subnet over which two or more OSPF routers have become neighbors - thereby being able to forward packets from one router to another across that network.
