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. Protocol Independent Multicast sparse-mode routing protocol.






2. An event in which a new packet arrives - needing to be placed into a queue - and the queue is full






3. A method of providing dynamically configured spoke-to-spoke VPN connectivity in a hub-and-spoke network that significantly reduces configuration required on the spoke routers compared to traditional IPsec VPN environments.






4. An IOS feature in which multiple routing tables and routing forwarding instances exist in a single router - with interfaces being assigned to one of the several VRFs. This feature allows separating of routing domains inside a single router platform.






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






6. A mechanism that counters collisions caused by hidden nodes. If enabled - the station or access point must first send an RTS frame and receive a CTS frame before sending each data frame.






7. The most significant bit in the most significant byte of an Ethernet MAC address - its value implies that the address is a unicast MAC address (binary 0) or not (binary 1).






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






9. When a PIM-SM router switches from RPT to SPT - it sends a PIM-SM Prune message for the source and the group with the RP bit set to its upstream router on the shared tree. RFC 2362 uses the notation PIM-SM (S - G) RP-bit Prune for this message.






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






11. Customer edge.






12. 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






13. With shaping - the number of bits allowed to be sent every Tc. Also defines the size of the token bucket when Be = 0.






14. An 802.1w RSTP port state in which the port is not forwarding or receiving; covers 802.1d port states disabled - blocking - and listening.






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






16. 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.






17. The process of forwarding packets through a router. Also call IP routing.






18. Defined in IEEE 802.1d - a protocol used on LAN bridges and switches to dynamically define a logical network topology that allows all devices to be reached - but prevents the formation of loops.






19. An NTP mode in which an NTP host adjusts its clock in relation to an NTP server's clock.






20. 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.






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






22. Cisco Wireless LAN Solution Engine.






23. An FRF standard for Frame Relay-to-ATM Service Interworking in which both DTEs use Frame Relay - with ATM in between.






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






25. Label Switch Router.






26. Cisco Express Forwarding.






27. A characteristic of OSPF interfaces that determines whether a DR election is attempted - whether or not neighbors must be statically configured - and the default Hello and Dead timer settings.






28. Database Description.






29. A term used with Cisco LAN switches - referring to a DSCP value used when making QoS decisions about a frame. This value may not be the actual DSCP value in the IP header encapsulated inside the frame.






30. Hot Standby Router Protocol.






31. Peak information rate.






32. Link-State Update.






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






34. A commonly used name for Multi-VRF CE.






35. Copper cable with RJ-45 connectors in which a twisted pair at pins 1 -2 on the first end of the cable is connected to pins 3 -6 on the other end - with a second pair connected to pins 3 -6 on the first end and pins 1 -2 on the other end.






36. Time Interval.






37. Network Based Application Recognition.






38. An OSPF external route for which internal OSPF cost is not added to the cost of the route as it was redistributed into OSPF.






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






40. Enhanced Local Management Interface.






41. Variable name for the time interval used by shapers and by CAR.






42. With RIP - a per-route timer (default 180 seconds) that begins when a route's metric changes to a larger value.






43. 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






44. 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.






45. Neighbor Discovery Protocol.






46. Protects against problems caused by unidirectional links between two switches. Watches for loss of received Hello BPDUs - in which case it transitions to a loop-inconsistent state instead of transitioning to a forwarding state.






47. An 802.1d STP port state in which the port sends and receives frames.






48. Service set identifier.






49. A process used in routers that are encrypting traffic to permit egress QoS actions to be taken on traffic that is being encrypted on that router. QoS pre-classification keeps a copy of each packet to be encrypted in memory long enough to take the app






50. Spanning Tree Protocol.
