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






2. Data Set Ready.






3. The information maintained by a router for each multicast entry in its multicast routing table - such as incoming interface - outgoing interface list - Uptime timer - Expire timer - etc.






4. Superframe






5. A Cisco-proprietary feature. After a Cisco multicast router receives IGMP Join or Leave messages from hosts - it communicates to the connected Cisco switches - telling them which hosts (based on their unicast MAC addresses) have joined or left each m






6. In the context of SNMP - the Inform command is sent by an SNMP manager to communicate a set of variables - and their values - to another SNMP manager. The main purpose is to allow multiple managers to exchange MIB information - and work together - wi






7. The IP address to which Label Distribution Protocol (LDP) sends LDP Hellos. Also used in IP multicast to send packets to all multicast routers.






8. A basic form of traffic shaping that is applied to an interface or subinterface. By default - it shapes all traffic leaving the interface - but can be modified by using an access control list. The access list controls only what traffic is shaped; GTS






9. Backup designated router.






10. A term referring to the process of applying the Message Digest 5 (MD5) algorithm to a string - resulting in another value. The original string cannot be easily computed even when the hash is known - making this process a strong method for storing pas






11. A term referring to how a router views a BGP peer relationship - in which the peer is in another AS.






12. The command used to initialize a SPAN or RSPAN session on a Catalyst switch.






13. 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






14. Defined in IEEE 802.1s - a specification for multiple STP instances when using 802.1Q trunks






15. 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.






16. 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






17. Designed to solve the problems of multicast duplication and multicast routing loops. For every multicast packet received - a multicast router examines its source IP address - consults its unicast routing table - determines which interface it would us






18. A BGP neighbor state in which the BGP neighbors have stabilized and can exchange routing information using BGP Update messages.






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






20. 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.






21. A name used for DS3 lines inside the North American TDM hierarchy.






22. 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.






23. Refers to how a router views a BGP peer relationship - in which the peer is in the same AS.






24. A method of obtaining an IPv6 address that uses DHCPv6. See also stateless autoconfiguration.






25. A Cisco-proprietary BGP feature. The administrative weight can be assigned to each NLRI and path locally on a router - impacting the local router's choice of the best BGP routes. The value cannot be communicated to another router.






26. An EIGRP message that is used to ask neighboring routers to verify their route to a particular subnet. Query messages require an Ack.






27. An 802.1d STP transitory port state in which the port does not send or receive frames - but does learn the source MAC addresses from incoming frames.






28. A Cisco IOS queuing tool that uses MQC configuration commands - reserves a minimum bandwidth for some queues - provides high-priority scheduling for some queues - and polices those queues to prevent starvation of lower-priority queues during interfac






29. With EIGRP - for a particular route - the case in which the RD is lower than the FD.






30. Digital subscriber line - a common Internet service type for residential and business customers.






31. Defined in RFC 1293 - this protocol allows a Frame Relay-attached device to react to a received LMI "PVC up" message by announcing its Layer 3 addresses to the device on the other end of the PVC.






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






33. Network Address Translation.






34. A type of OSPF NSSA area for which neither external (type 5) LSAs are introduced - nor type 3 summary LSAs; instead - the ABRs originate and inject default routes into the area. External routes can be injected into a totally NSSA area.






35. Jargon used to refer to the first of two buckets in the dual token bucket model; its size is Bc.






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






37. A wireless LAN physical layer that is backward compatible with 802.11b and operates at up to 54-Mbps data rates using OFDM in the 2.4-GHz band.






38. 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






39. A tunneling protocol that can be used to encapsulate many different protocol types - including IPv4 - IPv6 - IPsec - and others - to transport them across a network.






40. Challenge Handshake Authentication Protocol.






41. Reverse ARP.






42. Neighbor Solicitation.






43. RFC 1918-defined IPv4 network numbers that are not assigned as public IP address ranges - and are not routable on the Internet. Intended for use inside enterprise networks.






44. A 3-bit field in the first 3 bits of the ToS byte in the IP header - used for QoS marking.






45. With EIGRP - a router sharing the same primary subnet - with which Hellos are exchanged - parameters match - and with which routes can be exchanged.






46. Border Gateway Protocol.






47. Generic routing encapsulation.






48. An E-LSR in an MPLS VPN network whose role in a particular discussion is to receive unlabeled packets over customer links and then forward the packets as labeled packets into the MPLS network.






49. 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.






50. A routing protocol feature for which the routing protocol sends routing updates immediately upon hearing about a changed route - even though it may normally only send updates on a regular update interval.
