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 reservation of a minimum bandwidth for each queue.






2. A queuing tool's logic by which it selects the next packet to dequeue from its many queues.






3. EAP over LAN.






4. Inter-Switch Link.






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






6. Quantum value.






7. Auto-Rendezvous Point. Cisco-proprietary protocol that can be used to designate an RP and send RP-Announce messages that advertise its IP address and groups. Also - it can be used to designate a mapping agent that interprets what IP address RP is adv






8. 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






9. A feature of Ethernet NICs. When the NIC transmits an electrical signal - it "loops" the transmitted electrical current back onto the receive pair. By doing so - if another NIC transmits a frame at the same time - the NIC can detect the overlapping r






10. Temporal Key Integrity Protocol.






11. A logical concept that represents the path over which frames travel between DTEs. VCs are particularly useful when comparing Frame Relay to leased physical circuits.






12. An EIGRP message that identifies neighbors - exchanges parameters - and is sent periodically as a keepalive function. Hellos do not require an Ack.






13. Clear To Send.






14. Dynamic Multipoint VPN.






15. Pulse code modulation.






16. An FRF standard for LFI for data (FRF.3) VCs.






17. 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.






18. An NTP mode in which two or more NTP servers mutually synchronize their clocks.






19. This term has two BGP-related definitions. First - it is the normal process in which a router - before sending an Update to an eBGP peer - adds its local ASN to the beginning of the AS_PATH path attribute. Second - it is the routing policy of purpose






20. A wireless LAN physical layer that is backward compatible with 802.11b and operates at up to 54-Mbps data rates using OFDM in the 2.4-GHz band.






21. An STP timer that dictates how long a switch should wait when it ceases to hear Hellos.






22. With private VLANs - a secondary VLAN in which the ports can send and receive frames with each other - but not with ports in other secondary VLANS.






23. A category used by a policer to classify packets relative to the traffic contract. With two-color policers - these packets are considered to be above the contract; for three-color - these packets are above the Bc setting - but within the Be setting.






24. 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.






25. A wireless LAN physical layer that operates at up to 11-Mbps data rates using DSSS in the 2.4-GHz band.






26. The process of changing the electrical characteristics on a transmission medium - based on defined rules - to represent data.






27. The first 6 bits of the DS field - used for QoS marking.






28. Port Aggregation Protocol.






29. An optimized Layer 3 forwarding path through a router. Fast switching optimizes routing table lookup by creating a special - easily searched table of known flows between hosts.






30. A prestandard (at the time of publication) wireless LAN physical layer that offers data rates in the hundreds of megabits per second.






31. Enables a wireless client to securely roam between access points in the same subnet or between subnets with access point handoff times within 50 ms.






32. 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






33. A wireless LAN physical layer that operates at up to 54-Mbps data rates using OFDM in the 5-GHz band.






34. A type of OSPF packet used to exchange and acknowledge LSA headers. Sometimes called DBD.






35. The IP address used by hosts as the default gateway in a VRRP configuration. This address is shared by two or more VRRP routers - much as HSRP works.






36. Slow Start Threshold.






37. Internal BGP.






38. An optimized Layer 3 forwarding path through a router or switch. CEF optimizes routing table lookup by creating a special - easily searched tree structure based on the contents of the IP routing table. The forwarding information is called the Forward






39. A queue created by Cisco IOS as a result of the configuration of a queuing tool.






40. Internet Group Management Protocol.






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






42. A term referring generically to ways in which a router or switch can determine whether a particular device or user should be allowed access.






43. A message sent by a host when it wants to leave a group - addressed to the All Multicast Routers address 224.0.0.2.






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






45. PIM-DM is a method of routing multicast packets that depends on a flood-and-prune approach. PIM Dense Mode gets its name from the assumption that there are many receivers of a particular multicast group - close together (from a network perspective).






46. An E-LSR in an MPLS VPN network whose role in a particular discussion is to receive unlabeled packets over customer links and then forward the packets as labeled packets into the MPLS network.






47. With EIGRP - a route that is not a successor route - but that meets the feasibility condition; can be used when the successor route fails - without causing loops.






48. An EIGRP router's reaction to an input event - leading to the use of a feasible successor or going active on a route.






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






50. An IPv6/IPv4 tunneling method that allows isolated IPv6 domains to be connected over an IPv4 network.
