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






2. 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.






3. A set of all devices for which any frame sent by one of the devices would collide with any frames transmitted at the same time by any of the other devices in the set.






4. 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.






5. When subnetting a class A - B - or C address - the subnet for which all subnet bits are binary 0.






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






7. Label Distribution Protocol.






8. Out of Frame.






9. Inter-Switch Link.






10. An optional transitive BGP path attribute used to store 32-bit decimal values. Used for flexible grouping of routes by assigning the group the same COMMUNITY value. Other routers can apply routing policies based on the COMMUNITY value. Used in a larg






11. Inside telcos' original TDM hierarchy - a unit that combines multiple DS0s into a single channel






12. The rate at which a policer limits the bits exiting or entering the policer.






13. Penultimate hop popping.






14. A term used with Cisco LAN switches - referring to a queue treated with strict-priority scheduling.






15. A single instance of STP that is applied to multiple VLANs - typically when using the 802.1Q trunking standard.






16. The low-order 4 bits of the configuration register. These bits direct a router to load either ROMMON software (boot field 0x0) - RXBOOT software (boot field 0x1) - or a full-function IOS image.






17. The signal strength of the RF signal at the output of the radio card or access point transmitter - before being fed into the antenna. Measured in milliwatts - watts - or dBm.






18. A BGP feature that defines the IP TTL field value in packets sent between two eBGP peers. This feature is required when using IP addresses other than the interface IP address on the link between peers.






19. The characterization of how far EIGRP Query messages flow away from the router that first notices a failed route and goes active for a particular subnet.






20. 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.






21. The second most significant bit in the most significant byte of an Ethernet MAC address - a value of binary 0 implies that the address is a Universally Administered Address (UAA) (also known as Burned-In Address [BIA]) - and a value of binary 1 impli






22. In PIM-SM - the path of the group traffic that flows from the RP to the routers that need the traffic. It is also called the root-path tree (RPT) - because it is rooted at the RP.






23. 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.






24. A protocol used for reliable multicast and unicast transmissions. Used by EIGRP.






25. A router that is allowed to receive a packet from an OSPF router and then forward the packet to another OSPF router.






26. Maximum Response Time.






27. The operating mode of shaped round-robin that provides behavior like CBWFQ with bandwidth allocated between different traffic classes by a relative amount rather than absolute percentage of the available bandwidth.






28. The mandatory contention-based 802.11 access protocol that is also referred to as CSMA/CA.






29. A type of OSPF packet - used to communicate LSAs to another router.






30. The rate at which a shaper limits the bits exiting the shaper.






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






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






33. With RIP - the advertisement of a poisoned route out an interface - when that route was formerly not advertised out that interface due to split horizon rules.






34. Aka receiver's advertised window.






35. Sent by a PIM router - by default every 30 seconds - on every interface on which PIM is configured to discover neighbors - establish adjacency - and maintain adjacency.






36. Generic routing encapsulation.






37. Ethernet feature in which a NIC or Ethernet port can both transmit and receive at the same instant in time. It can be used only when there is no possibility of collisions. Loopback circuitry on NIC cards is disabled to use full duplex.






38. 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






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






40. An ITU standard Frame Relay header - including the DLCI - DE - FECN - and BECN bits in the LAPF header - and a frame check in the LAPF trailer.






41. A packet-scheduling algorithm used in Cisco switches that provides similar behavior to CBWFQ in shared mode and polices in shaped mode.






42. Data Set Ready.






43. Temporal Key Integrity Protocol.






44. Authentication - authorization - and accounting.






45. Label Switch Router.






46. 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.






47. 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.






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






49. An SPF calculation as a result of changes inside the same area as a router - for which the SPF run must examine the full LSDB.






50. A Cisco-proprietary messaging protocol implemented in WAN switches that can be used to signal network status - including congestion - independent of end-user frames and cells.
