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 mapping between each DSCP value and a WRED threshold - often used in Cisco LAN switches when performing WRED.






2. Copper cable with RJ-45 connectors in which the wire at pin 1 on one end is connected to pin 1 on the other end; the wire at pin 2 is connected to pin 2 on the other end; and so on.






3. The common set of IOS configuration commands that is used with each QoS feature whose name begins with "Class-Based."






4. Cisco IOS router feature by which a route map determines how to forward a packet - typically based on information in the packet other than the destination IP address.






5. A group of devices on one or more LANs that are configured (using management software) so that they can communicate as if they were attached to the same wire - when - in fact - they are located on a number of different LAN segments. Because VLANs are






6. Layer 2 payload compression.






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






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






9. Advanced Encryption Standard A superior encryption mechanism that is part of the 802.11i standard and has much stronger security than TKIP.






10. 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.






11. 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






12. In the context of SNMP - the Trap command is sent by an SNMP agent - to a manager - when the agent wants to send unsolicited information to the manager. Trap is not followed by a Response message from the receiving SNMP manager.






13. Layer x PDU.






14. A term used with Cisco LAN switches - referring to a queue treated with strict-priority scheduling.






15. The first 48 bits of an IPv6 global address - used for efficient route aggregation.






16. 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






17. Virtual circuit.






18. Ethernet feature in which a NIC or Ethernet port can both transmit and receive at the same instant in time. It can be used only when there is no possibility of collisions. Loopback circuitry on NIC cards is disabled to use full duplex.






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






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






21. An EIGRP router's reaction to an input event - leading to the use of a feasible successor or going active on a route.






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






23. Reported distance or Route Distinguisher.






24. A type of OSPF packet - used to communicate LSAs to another router.






25. A 3-bit field in an MPLS header used for marking frames.






26. Another name for 802.1Q-in-Q. See 802.1Q-in-Q.






27. Link Aggregation Control Protocol.






28. Records client authentication and roaming events - which are sent to the CiscoWorks Wireless LAN Solution Engine (WLSE) to monitor client associations to specific access points.






29. With routing protocols - the measurement of favorability that determines which entry will be installed in a routing table if more than one router is advertising that exact network and mask.






30. Out of Frame.






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






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






33. Diffusing Update Algorithm.






34. Extended Superframe.






35. Static length subnet masking.






36. With RIP - the regular interval at which updates are sent. Each interface uses an independent timer - defaulting to 30 seconds.






37. Provides dynamic inspection of traffic as it traverses the router. It uses Context-Based Access Control (CBAC) to look deeper into a packet than an access list can. It tracks outbound traffic and dynamically allows in responses to that traffic.






38. Area 0; the area to which all other OSPF areas much connect in order for OSPF to work.






39. Time-division multiplexing.






40. Message sent by a PIM-DM router to a downstream router when it receives a Graft message from the downstream router; sent using the unicast address of the downstream router.






41. Class-Based Weighted Fair Queuing.






42. Distance Vector Multicast Routing Protocol.






43. The characterization of how far EIGRP Query messages flow away from the router that first notices a failed route and goes active for a particular subnet.






44. A protocol used for reliable multicast and unicast transmissions. Used by EIGRP.






45. A BGP term referring to an IP prefix and prefix length.






46. Challenge Handshake Authentication Protocol.






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






48. A Cisco 12000 series router feature that combines the key features of LLQ and CQ to provide similar congestion-management features.






49. Weighted fair queuing.






50. A Cisco IOS configuration tool for routing protocols by which routing updates may be filtered.
