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. Extended Superframe.






2. 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.






3. Sent by a PIM-DM or PIM-SM router when it receives a multicast packet for a group on a LAN interface that is in the outgoing interface list for the group; includes the administrative distance of the unicast routing protocol used to learn the network






4. EIGRP jargon meaning that EIGRP has placed a route into active status.






5. 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.






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






7. Cisco IOS IP Service Level Agent feature. Provides for router-generated information useful for verifying network performance on a scheduled basis - and the associated reporting functions.






8. The specific frequency subband on which the radio card or access point is operating. The RF channel is set in the access point or ad hoc stations.






9. In BGP - a feature in which BGP routes cannot be considered to be a best route to reach an NLRI unless that same prefix exists in the router's IP routing table as learned via some IGP.






10. A type of IPv4 and IPv6 traffic designed primarily to provide one-to-many connectivity but unlike broadcast - has the capability to control the scope of traffic distribution.






11. A process on a computing device that accepts SNMP requests - responds with SNMP-structured MIB data - and initiates unsolicited Trap messages back to an SNMP management station.






12. A serial-line encoding standard that sends alternating positive and negative 3-volt signals for binary 1 - and no signal (0 V) for binary 0.






13. A Cisco switch feature that allows separation of ports as if they were in separate VLANs - while allowing the use of a single IP subnet for all ports.






14. The SNMP specifications - standardized in RFCs - defining the rules by which SNMP MIB variables should be defined.






15. Dynamic Host Configuration Protocol.






16. Tag Distribution Protocol.






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






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






19. Carrier sense multiple access with collision detection. A media-access mechanism where devices ready to transmit data first check the channel for a carrier. If no carrier is sensed for a specific period of time - a device can transmit. If two devices






20. Another term for summary route.






21. Out of Frame.






22. A route that is used for forwarding packets when the packet does not match any more specific routes in the IP routing table.






23. A Cisco-proprietary Layer 2 protocol that enables a router to communicate to a switch which multicast group traffic the router does and does not want to receive from the switch.






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






25. Link Access Procedure for Frame-Mode Bearer Services.






26. Voice over Frame Relay.






27. In the context of SNMP - the Get command is sent by an SNMP manager - to an agent - requesting the value of a single MIB variable identified in the request. The Get request identifies the exact variable whose value the manager wants to retrieve. Intr






28. 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






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






30. Loss of Frame.






31. Feasible distance.






32. Point-to-Point Protocol over Ethernet. A convention often used as the data link protocol over Cable in which Ethernet is used as the data link protocol - but with PPP being encapsulated inside Ethernet. The combination gives the data link features of






33. Neighbor Advertisement.






34. 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.






35. 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.






36. Area Border Router. An OSPF router that connects to the backbone area and to one or more non-backbone areas.






37. 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.






38. An 802.1w RSTP port state in which the port is not the Root Port but is available to become the root port if the current root port goes down.






39. An Internet standard (RFC 1305) that defines the messages and modes used for IP hosts to synchronize their time-of-day clocks.






40. With private VLANs - a secondary VLAN in which the ports can send and receive frames only with promiscuous ports in the primary VLAN.






41. 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






42. Internal BGP.






43. An FRF standard for LFI for VoFR (FRF.11) VCs - in which all voice frames are interleaved in front of data frames' fragments.






44. 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.






45. Peak information rate.






46. Committed information rate.






47. Virtual Router Redundancy Protocol.






48. In BGP - a set of routers inside a single administrative authority - grouped together for the purpose of controlling routing policies for the routes advertised by that group to the Internet.






49. A router that should not be used to forward packets between other routers. Other routers will not send Query messages to a stub router.






50. A list of interspersed alphanumeric literals and metacharacters that are used to apply complex matching logic to alphanumeric strings. Often used for matching AS_PATHs in Cisco routers.
