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 speed at which the access link is clocked. This choice affects the price of the connection and many aspects of traffic shaping and policing - compression - quality of service - and other configuration options.






2. An individual line in an ACL.






3. Service set identifier.






4. A type of OSPF packet used to acknowledge LSU packets.






5. Class-Based Marking.






6. 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.






7. A single label and link that is part of a complete LDP. See also label switched path.






8. A wireless LAN that includes the use of access points. Infrastructure mode connects wireless users to a wired network and allows wireless users to roam throughout a facility between different access points. All 802.11 data frames in an infrastructure






9. Weighted round-robin.






10. Jargon used to refer to the second of two buckets in the dual token bucket model; its size is Be.






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






12. The 802.1X driver that supplies a username/password prompt to the user and sends/receives the EAPoL messages.






13. IP routing The simplest MPLS application - involving the advertisement of an IGP to learn IP routes - and LDP or TDP to advertise labels.






14. 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 forward the attribute unchanged (tran






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






16. The notation in a Cisco IOS IP routing table that identifies the route used by that router as the default route.






17. A type of AS_PATH segment consisting of an unordered list of ASNs consolidated from component subnets of a summary BGP route.






18. 64 bits at the end of an IPv6 global address - used to uniquely identify each host in a subnet.






19. A mechanism in which VLAN information can extend over another set of 802.1Q trunks by tunneling the original 802.1Q traffic with another 802.1Q tag. It allows a service provider to support transparent VLAN services with multiple customers - even if t






20. A reserved value for the BGP COMMUNITY path attribute that implies that the route should not be advertised outside the local confederation sub-AS.






21. A group of devices on one or more LANs that are configured (using management software) so that they can communicate as if they were attached to the same wire - when - in fact - they are located on a number of different LAN segments. Because VLANs are






22. The RFC 1997 name for the reserved COMMUNITY path attribute known to Cisco IOS as LOCAL_AS. (See LOCAL_AS.)






23. 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






24. An FRF standard for payload compression.






25. A characterization of a BGP path attribute in which all BGP implementations must support and understand the attribute (well known) - and all BGP Updates must include the attribute (mandatory).






26. With EIGRP - the metric (distance) of a route as reported by a neighboring router.






27. The 32-bit number used to represent an OSPF router.






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






29. A BGP feature that overcomes the requirement of a full mesh of iBGP peers inside a single AS by separating the AS into multiple sub-autonomous systems.






30. In TCP - a TCP host sets the TCP header's Window field to the number of bytes it allows the other host to send before requiring an acknowledgement. In effect - the receiving host - by stating a particular window size - grants the sending host the rig


31. Router-Port Group Management Protocol.






32. Class Selector.






33. Network Based Application Recognition.






34. 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






35. A method for optimizing the flow of multicast IP packets passing through a LAN switch. The switch using IGMP snooping examines IGMP messages to determine which ports need to receive traffic for each multicast group.






36. 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.






37. Modular QoS CLI.






38. A protection against problems caused by unidirectional links between two switches. Uses messaging between switches to detect the loop - err-disabling the port when the link is unidirectional.






39. A type of OSPF packet used to discover neighbors - check for parameter agreement - and monitor the health of another router.






40. Link-State Update.






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






42. The protocol used in IPv6 for many functions - including address autoconfiguration - duplicate address detection - router - neighbor - and prefix discovery - neighbor address resolution - and parameter discovery.






43. The process of sending an infinite-metric route in routing updates when that route fails.






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






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






46. Rapid Spanning Tree Protocol.






47. A specification for the 64-bit interface ID in an IPv6 address - composed of the first half of a MAC address - hex FFFE - and the last half of the MAC.






48. Committed information rate.






49. Router Advertisement.






50. A type of spread spectrum that spreads RF signals over the frequency spectrum by representing each data bit by a longer code. 802.11b specifies the use of DSSS.
