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. Multiple Spanning Trees.






2. Context-Based Access Control.






3. Policing in which two rates are metered - and packets are placed into one of three categories (conform - exceed - or violate).






4. The signal strength of the RF signal at the output of the radio card or access point transmitter - before being fed into the antenna. Measured in milliwatts - watts - or dBm.






5. In BGP - a feature in which BGP routes cannot be considered to be a best route to reach an NLRI unless that same prefix exists in the router's IP routing table as learned via some IGP.






6. Database Description.






7. On a single computer - one layer provides a service to a higher layer. The software or hardware that implements the higher layer requests that the next lower layer perform the needed function.






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






9. Ethernet feature in which a NIC or Ethernet port can only transmit or receive at the same instant in time - but not both. Half duplex is required when a possibility of collisions exists.






10. A BGP path attribute that lists the next-hop IP address used to reach an NLRI.






11. An address type in IPv6 networks that is used only on the local link and never beyond that scope.






12. A type of spread spectrum that spreads RF signals over the frequency spectrum by representing each data bit by a longer code. 802.11b specifies the use of DSSS.






13. An MQC configuration style by which one policy map calls a second policy map. For example - a shaping policy map can call an LLQ policy map to implement LLQ for packets shaped by CB Shaping.






14. Variable name for the time interval used by shapers and by CAR.






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






16. An 802.1w RSTP port state in which the port is not the Root Port but is available to become the root port if the current root port goes down.






17. A 3-bit field in an ISL header used for marking frames. Also - used generically to refer to either the ISL CoS field or the 802.1Q User Priority field.






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 dotted-decimal number that represents a subnet. It is the lowest numeric value in the range of IP addresses implied by a subnet number and prefix/mask.






20. 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.






21. In shaping and policing - commonly used to refer to the shaping or policing rate. For WAN services - a common reference to the bit rate defined in the WAN service business contract for each VC.






22. A table used by CEF that holds information about adjacent IP hosts to which packets can be forwarded.






23. A neighbor state that signifies the other router has reached neighbor status - having passed the parameter check. The FIB entry details the information needed for forwarding: the next-hop router and the outgoing interface - in an optimized mtrie stru






24. A term used with Cisco LAN switches - referring to a DSCP value used when making QoS decisions about a frame. This value may not be the actual DSCP value in the IP header encapsulated inside the frame.






25. A type of AS_PATH segment consisting of an unordered list of ASNs consolidated from component subnets of a summary BGP route.






26. 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.






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






28. A contiguous group of data links that share the same OSPF area number.






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






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






31. A method that creates three thresholds per egress queue in the Cisco 3560 switch. Traffic is divided into the three queues based on CoS value - and given different likelihoods (weight) for tail drop when congestion occurs based on which egress queue






32. Time to Live.






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






34. The process of taking the IP - UDP - and RTP headers of a voice or video packet - compressing them - and then uncompressing them on the receiving router.






35. Aka network layer reachability information.






36. An optional transitive BGP path attribute that - for a summary route - lists the BGP RID and ASN of the router that created the summary.






37. Network Control Protocol.






38. Forwarding Equivalence Class.






39. Multicast addresses that are not assigned by IANA.






40. Quantum value.






41. In the context of SNMP - the Response command is sent by an SNMP agent - back to a manager - in response to any of the three types of Get requests - or in response to a Set request. It is also used by a manager in response to a received Inform comman






42. An 802.1d STP port state in which the port does not send or receive frames - except for listening for received Hello BPDUs.






43. A BGP path attribute that is communicated throughout a single AS to signify which route of multiple possible routes is the best route to be taken when leaving that AS. A larger value is considered to be better.






44. Class of Service.






45. Data Set Ready.






46. Challenge Handshake Authentication Protocol.






47. An NTP client that assumes that a server will send NTP broadcasts - removing the requirement for the client to have the NTP server's IP address preconfigured.






48. 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.






49. 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.






50. A queuing tool's logic by which it selects the next packet to dequeue from its many queues.
