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. Classless interdomain routing.






2. 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






3. An MPLS term describing designs in which one or more MPLS customer sites can be reached from multiple other VPNs.






4. Inverse ARP.






5. A communication protocol between hosts and a multicast router by which routers learn of which multicast groups' packets need to be forwarded onto a LAN.






6. In the context of SNMP - the Set command is sent by an SNMP manager - to an agent - requesting that the agent set a single identified variable to the stated value. The main purpose is to allow remote configuration and remote operation - such as shutt






7. The underlying algorithms associated with RIP.






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






9. IP multicast address range from 224.0.0.0 through 239.255.255.255.






10. Data Set Ready.






11. Permanent virtual circuit.






12. The destination VLAN for an RSPAN session.






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






14. 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.






15. The algorithm used by OSPF and IS-IS to compute routes based on the LSDB.






16. Cisco IOS Embedded Event Manager - a feature that monitors events on a router and reports their results. Principally intended to increase availability - EEM provides flexible - granular detection and alerting functions.






17. A 3-tuple consisting of an IP address - port number - and transport layer protocol. TCP connections exist between a pair of sockets.






18. Timer An STP timer that dictates how long a port should stay in the listening state and the learning state.






19. An MQC-based feature of IOS that is used to classify and mark packets for QoS purposes.






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






21. A type of AS_PATH segment consisting of an ordered list of ASNs through which the route has been advertised.






22. The one VLAN on an 802.1Q trunk for which the endpoints do not add the 4-byte 802.1Q tag when transmitting frames in that VLAN.






23. The most recent standardized set of generic SNMP MIB variables - defined in RFC 1213 and updated in RFCs 2011 through 2013.






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






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






26. Committed Burst.






27. A WFQ term referring to its drop logic - which is similar to tail-drop behavior.






28. Reported distance or Route Distinguisher.






29. A DiffServ PHB - based on DSCP EF (decimal 46) - that provides low-latency queuing behavior as well as policing protection to prevent EF traffic from starving queues for other types of traffic.






30. The operating mode of shaped round-robin that provides a low-latency queue with policing.






31. In OSPF - a router that is prepared to take over the designated router.






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






33. With EIGRP - a route that is not a successor route - but that meets the feasibility condition; can be used when the successor route fails - without causing loops.






34. A workstation or server configured to collect and present RMON data for reporting purposes.






35. A definition that determines the data structure and information implied by a particular LSA.






36. Defined in RFC 2289 - a mechanism by which a shared key and a secret key together feed into a hash algorithm - creating a password that is transmitted over a network. Because the shared key is not reused - the hash value is only valid for that indivi






37. Gateway Load Balancing Protocol.






38. Router ID.






39. Dynamic ARP Inspection.






40. 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






41. With private VLANs - a port that can send and receive frames with all other ports in the private VLAN.






42. Custom queuing






43. A type of OSPF stub area that - unlike stub areas - can inject external routes into the NSSA area.






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






45. Wired Equivalent Privacy.






46. Network Layer Protocol ID is a field in the RFC 2427 header that is used as a Protocol Type field in order to identify the type of Layer 3 packet encapsulated inside a Frame Relay frame.






47. A name used for DS3 lines inside the European TDM hierarchy.






48. Network Time Protocol.






49. Point-to-Point Protocol over Ethernet. A convention often used as the data link protocol over Cable in which Ethernet is used as the data link protocol - but with PPP being encapsulated inside Ethernet. The combination gives the data link features of






50. With routing protocols - the process by which the router receiving a routing update determines if the routing update came from a trusted router.
