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. Time-division multiplexing.






2. Dynamic Trunking Protocol.






3. Controls access to the Internet in public wireless LANs.






4. Layer 2 payload compression.






5. An ITU standard Frame Relay header - including the DLCI - DE - FECN - and BECN bits in the LAPF header - and a frame check in the LAPF trailer.






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






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






8. Software-based collection and reporting tool for data reported by NetFlow.






9. The RFC 1997 name for the reserved COMMUNITY path attribute known to Cisco IOS as LOCAL_AS. (See LOCAL_AS.)






10. A 48-bit address that is calculated from a Layer 3 multicast address by using 0x0100.5E as the multicast vendor code (OUI) for the first 24 bits - always binary 0 for the 25th bit - and copying the last 23 bits of the Layer 3 multicast address.






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






12. Classless interdomain routing.






13. The combination of PVST+ and Rapid Spanning Tree. It provides subsecond convergence time and is compatible with PVST+ and MSTP.






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






15. Frame Relay Forum.






16. The actual number of packets in a queue at a particular time.






17. A single label and link that is part of a complete LDP. See also label switched path.






18. A router that should either permanently or temporarily not be used as a transit router. Can wait a certain time after OSPF process start - or after BGP notifies OSPF that BGP has converged - before ceasing to be a stub router.






19. A router feature used when a router sees an ARP request searching for an IP host's MAC - when the router believes the IP host could not be on that LAN because the host is in another subnet. If the router has a route to reach the subnet where the ARP-






20. In IPv6 - the Neighbor Discovery message used by an IPv6 node to request information about a neighbor or neighbors.






21. The multicast IP address 224.0.0.5 - listened for by all OSPF routers.






22. A feature of Ethernet NICs. When the NIC transmits an electrical signal - it "loops" the transmitted electrical current back onto the receive pair. By doing so - if another NIC transmits a frame at the same time - the NIC can detect the overlapping r






23. The process of taking routes known through one routing protocol and advertising those routes with another routing protocol.






24. A wireless LAN physical layer that operates at up to 11-Mbps data rates using DSSS in the 2.4-GHz band.






25. A Cisco-proprietary protocol that defines how to perform authentication between an authenticator (for example - a router) and an authentication server that holds a list of usernames and passwords.






26. Weighted tail drop.






27. In the context of SNMP - the Get command is sent by an SNMP manager - to an agent - requesting the value of a single MIB variable identified in the request. The Get request identifies the exact variable whose value the manager wants to retrieve. Intr






28. The Cisco IOS Router IP Traffic Export feature - intended for intrusion detection - exports IP traffic that has signs of an attack - such as duplicate IP packets simultaneously received on two or more of a router's interfaces.






29. Link-state database.






30. With EIGRP - the metric value for the lowest-metric route to a particular subnet.






31. Penultimate hop popping.






32. A router that is not an ABR or ASBR in that all of its interfaces connect to only a single OSPF area.






33. Forward Explicit Congestion Notification.






34. Receiver's advertised window.






35. An OSPF area into which external (type 5) LSAs are not introduced by its ABRs; instead - the ABRs originate and inject default routes into the area.






36. Data Terminal Ready.






37. Modified Deficit Round-Robin.






38. Priority queue and priority queuing.






39. In IPv6 - an address used in the Neighbor Discovery (ND) process. The format for these addresses is FF02::1:FF00:0000/104 - and each IPv6 host must join the corresponding group for each of its unicast and anycast addresses.






40. Each 802.11 station passively monitors each RF channel for a specific amount of time and listens for beacons. Stations use the signal strengths of found beacons to determine the access point or ad hoc network with which to attempt association.






41. 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.






42. A wireless LAN that offers connections to the Internet from public places - such as airports - hotels - and coffee shops.






43. Customer edge.






44. Designated router.






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






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






47. As defined in RFC 3623 - graceful restart allows for uninterrupted forwarding in the event that an OSPF router's OSPF routing process must restart. The router does this by first notifying the neighbor routers that the restart is about to occur; the n






48. The content engine in a WCCP cluster - which determines how traffic will be distributed within the cluster.






49. Dynamic ARP Inspection.






50. Link-State Update.
