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 term referring to the MQC class-map command and its related subcommands - which are used for classifying packets.






3. 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.






4. 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.






5. The password required by the enable command. Also - this term may specifically refer to the password defined by the enable password command.






6. Defines a particular behavior for FTP regarding the establishment of TCP data connections. In passive mode - an FTP server uses the FTP PORT command - over the FTP control connection - to tell the FTP client the port on which the server will be liste






7. 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.






8. An IPv6 migration strategy in which a host or router supports both IPv4 and IPv6 natively.






9. Variable-length subnet masking.






10. Tag Distribution Protocol.






11. Edge LSR.






12. 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






13. With EIGRP - the timer used to determine when a neighboring router has failed - based on a router not receiving any EIGRP messages - including Hellos - in this timer period.






14. An NTP mode in which an NTP host does not adjust its clock - but in which it sends NTP messages to clients so that the clients can update their clocks based on the server's clock.






15. Link-state advertisement.






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






17. With routing protocols - the measurement of favorability that determines which entry will be installed in a routing table if more than one router is advertising that exact network and mask.






18. The portions of PPP focused on features that are related to specific Layer 3 protocols.






19. A set of parameters for CBAC to perform in its traffic inspection process.






20. 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).






21. An architecture and set of documents that defines Cisco's best recommendations for how to secure a network.






22. Data terminal equipment.






23. The RMON function of sending a notification to an RMON collector or the console. Triggered by an RMON event.






24. The multicast addresses assigned by IANA.






25. Distance Vector Multicast Routing Protocol.






26. A multicast routing protocol that operates in dense mode and depends on the OSPF unicast routing protocol to perform its multicast functions.






27. A conceptual model used by shapers and policers to represent their internal logic.






28. A term used with WFQ for the number assigned to a packet as it is enqueued into a WFQ. WFQ schedules the currently lowest SN packet next.






29. Discard Eligible.






30. DCE devices are one of two devices on either end of a communications circuit - specifically the device with more control over the communications. Frame Relay switches are DCE devices. DCEs are also known as data circuit-terminating equipment (DTE).






31. An IEEE standard that - when used with EAP - provides user authentication before their connected switch port allows the device to fully use the LAN.






32. 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






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






34. Pulse code modulation.






35. A contiguous group of data links that share the same OSPF area number.






36. A type of logic for how a router uses a default route. A convention for discussing and thinking about IP addresses by which class A - B - and C default network prefixes (of 8 - 16 - and 24 bits - respectively) are considered.






37. Aka receiver's advertised window.






38. A mapping between each DSCP value and a corresponding CoS value - often used in Cisco LAN switches when performing classification for egress queuing.






39. Direct sequence spread spectrum.






40. Secure Shell protocol used for character-oriented command-line access and configuration. A highly secure alternative to Telnet.






41. 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.






42. An EIGRP message that is used by neighbors to reply to a query. Reply messages require an Ack.






43. Any OSPF neighbor for which the database flooding process has completed.






44. An enhanced version of T1 framing - as compared with the earlier Superframe (D4) standard.






45. A number between 1 and 64 -511 (public) and 64 -512 and 65 -535 (private) assigned to an AS for the purpose of identifying a specific BGP domain.






46. A routing protocol feature by which the routing update includes only routes that have changed - rather than include the entire set of routes.






47. The term referring to a group of iBGP routers in a confederation - with the group members being assigned a hidden ASN for the purposes of loop avoidance.






48. 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.






49. Alternate Mark Inversion. 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.






50. Loss of Frame.
