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 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.






2. 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.






3. Feasible distance.






4. With a routing update - or routing table entry - the portion of a route that defines the next router to which a packet should be sent to reach the destination subnet. With routing protocols - the Next Hop field may define a router other than the rout






5. An intrusion detection system that safeguards the wireless LAN from malicious and unauthorized access.






6. In IPv6 DNS - the IPv6 equivalent of an IPv4 DNS A record.






7. Virtual Routing and Forwarding table.






8. Ethernet process by which devices attached to the same cable negotiate their speed and the duplex settings over the cable.






9. A Cisco-proprietary messaging protocol used to negotiate the dynamic creation of PortChannels (EtherChannels) and to choose which ports can be placed into an EtherChannel.






10. An Internet standard authentication protocol that uses secure hashes and a three-way handshake to perform authentication over a PPP link.






11. 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.






12. 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-






13. On a serial cable - the pin lead set by the DTE to tell the DCE that the DTE wants to send data.






14. Generic routing encapsulation.






15. Cisco-proprietary STP feature in which a switch port monitors for incoming superior Hellos - and reacts to a superior Hello to prevent any switch connected to that port from becoming root.






16. A T1 alarm state that occurs when a device has detected a local LOF/LOS/AIS condition. The device in Red alarm state then sends a Yellow alarm signal.






17. A number between 1 and 64 -511 (public) and 64 -512 and 65 -535 (private) assigned to an AS for the purpose of identifying a specific BGP domain.






18. Voice over Frame Relay.






19. A predefined VC. A PVC can be equated to a leased line in concept.






20. An MPLS VPN term referring to a router at a customer site that does not implement MPLS.






21. Finish time.






22. Direct sequence spread spectrum.






23. A Layer 3 forwarding path through a router that does not optimize the forwarding path through the router.






24. A BGP path attribute that implies how the route was originally injected into some router's BGP table.






25. A message sent by a multicast router - by default every 125 seconds - on each of its LAN interfaces to determine whether any host wants to receive multicast traffic for any group.






26. Link Control Protocol.






27. The mandatory contention-based 802.11 access protocol that is also referred to as CSMA/CA.






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






29. 16 bits between the interface ID and global routing prefix in an IPv6 global address - used for subnet assignment inside an enterprise.






30. Version 6 of the IP protocol - which uses 128-bit IP addresses.






31. Each 802.11 station periodically sends a probe request frame on each RF channel and monitors probe response frames that all access points within range send back. Stations use the signal strength of the probe response frames to determine which access






32. The RMON function of sending a notification to an RMON collector or the console. Triggered by an RMON event.






33. A component of the IOS IP SLA feature. An IP SLA responder is a router configured to respond to a particular IP SLA message initiated by another router - allowing the routers to work together to provide performance information including UDP jitter an






34. An STP timer that dictates how long a switch should wait when it ceases to hear Hellos.






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






36. Another term for summary route.






37. Dynamic Host Configuration Protocol.






38. A vendor consortium that formerly worked to further Frame Relay common vendor standards.






39. Measured Round-Trip Time.






40. Protocol data unit.






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






42. The feature in a Cisco IOS device by which a terminal session's previously typed commands are remembered - allowing the user to recall the old commands to the command line through a simple key sequence (for example - the up-arrow key).






43. A serial-line encoding standard like B8ZS - but with each set of four consecutive 0s being changed to include a Bipolar Violation to maintain synchronization.






44. The first 6 bits of the DS field - used for QoS marking.






45. Reliable Transport Protocol.






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






47. 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.






48. Smoothed Round-Trip Time.






49. A router that should not be used to forward packets between other routers. Other routers will not send Query messages to a stub router.






50. Quantum value.
