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






2. Digital Signal Level 1.






3. 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






4. With OSPF - the OSPF router that wins an election amongst all current neighbors. The DR is responsible for flooding on the subnet - and for creating and flooding the type 2 LSA for the subnet.






5. A term referring to the MQC policy-map command and its related subcommands - which are used to apply QoS actions to classes of packets.






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






7. A Cisco-proprietary protocol - used by LAN switches to communicate VLAN configuration.






8. Sending a message from a single source or multiple sources to selected multiple destinations across a Layer 3 network in one data stream.






9. Virtual circuit.






10. 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.






11. An Internet standard authentication protocol that uses clear-text passwords and a two-way handshake to perform authentication over a PPP link.






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






13. 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






14. A bit in the Frame Relay header that - when set to 1 - means that if a device needs to discard frames - it should discard the frames with DE 1 first.






15. A subset of a classful IP network - as defined by a subnet mask - which used to address IP hosts on the same Layer 2 network in much the same way as a classful network is used.






16. 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.






17. 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.






18. A term referring to the MQC service-policy command - which is used to enable a policy map on an interface.






19. Advanced Encryption Standard A superior encryption mechanism that is part of the 802.11i standard and has much stronger security than TKIP.






20. An 802.1w RSTP port state in which the port is an alternative Designated Port on some LAN segment.






21. The definitions for a particular set of data variables - with those definitions following the SMI specifications. See also SMI.






22. Type of Service byte.






23. Instead of advertising all routes out a particular interface - the routing protocol omits the routes whose outgoing interface field matches the interface out which the update would be sent.






24. The portion of PPP focused on features that are unrelated to any specific Layer 3 protocol.






25. Often used synonymously with neighbor - but with emphasis on the fact that all required parameters match - allowing routing updates to be exchanged between the routers.






26. The original MPLS protocol used to advertise the binding (mapping) information about each particular IP prefix and associated label. It is slightly different from LDP - but functionally equivalent. See also LDP.






27. A switch feature that limits the number of allowed MAC addresses on a port - with optional limits based on the actual values of the MAC addresses.






28. Rapid Spanning Tree Protocol.






29. A message sent by a router - after receiving a Leave message from a host - to determine whether there are still any active members of the group. The router uses the group address as the destination address.






30. 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.






31. The destination VLAN for an RSPAN session.






32. VTP process that prevents the flow of broadcasts and unknown unicast Ethernet frames in a VLAN from being sent to switches that have no ports in that VLAN.






33. 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.






34. Auto-Rendezvous Point. Cisco-proprietary protocol that can be used to designate an RP and send RP-Announce messages that advertise its IP address and groups. Also - it can be used to designate a mapping agent that interprets what IP address RP is adv






35. Defined in RFC 3748 - the protocol used by IEEE 802.1X for exchanging authentication information.






36. Generic routing encapsulation.






37. Time to Live.






38. Sequence number.






39. Out of Frame.






40. A wireless LAN that only includes wireless users and no access points. 802.11 data frames in an ad hoc network travel directly between wireless users.






41. 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.






42. The range 233.0.0.0 through 233.255.255.255 that IANA has reserved (RFC 2770) on an experimental basis. It can be used by anyone who owns a registered autonomous system number to create 256 global multicast addresses.






43. Prefix list.






44. On a serial cable - the pin lead set by the DTE to imply that the DTE is ready to signal using pin leads.






45. 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.






46. 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.






47. A BGP process by which a router reapplies routing policy configuration (route maps - filters - and the like) based on stored copies of sent and received BGP Updates.






48. Dynamic Multipoint VPN.






49. A security standard that includes both TKIP and AES and was ratified by the Wi-Fi Alliance.






50. Operation - Administration - and Maintenance.
