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 logical group of content engines running WCCP between them. The lead content engine determines the traffic distribution within the cluster - for optimum performance and scalability.






2. EAP over LAN.






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






4. A standard (RFC 951) protocol by which a LAN-attached host can dynamically broadcast a request for a server to assign it an IP address - along with other configuration settings - including a subnet mask and default gateway IP address.






5. 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.






6. A conceptual model used by shapers and policers to represent their internal logic.






7. In two-rate policing - the second and higher rate defined to the policer.






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






9. A name used for DS1 lines inside the North American TDM hierarchy.






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






11. A Cisco switch feature that permits limiting traffic arriving at switch ports by percentage or absolute bandwidth. Separate thresholds are available per port for unicast - multicast - and broadcast traffic.






12. A message that each host sends - either in response to a router Query message or on its own - to all multicast groups for which it would like to receive multicast traffic.






13. Common Spanning Tree.






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






15. Inside telcos' original TDM hierarchy - a unit that combines multiple DS0s into a single channel






16. Hot Standby Router Protocol.






17. Cisco Express Forwarding.






18. An FRF standard for Frame Relay-to-ATM Service Interworking in which one DTE uses Frame Relay and one uses ATM.






19. An optional nontransitive BGP path attribute that lists the route reflector cluster IDs through which a route has been advertised - as part of a loop-prevention process similar to the AS_PATH attribute.






20. Removing unwanted VLANs from a Layer 2 path.






21. On a serial cable - the pin lead set by the DCE to imply a working link.






22. Secure Copy Protocol - one of the many ways of transferring files to and from Cisco IOS routers and switches.






23. An effort to reduce the query scope with EIGRP - using route summarization or EIGRP stub routers.






24. The multicast addresses assigned by IANA.






25. 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






26. Label switched path.






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






28. The term referring to a group of iBGP routers in a confederation - with the group members being assigned a hidden ASN for the purposes of loop avoidance.






29. A Cisco IOS queuing tool that uses MQC configuration commands - reserves a minimum bandwidth for some queues - provides high-priority scheduling for some queues - and polices those queues to prevent starvation of lower-priority queues during interfac






30. The Frame Relay protocol used between a DCE and DTE to manage the connection. Signaling messages for SVCs - PVC Status messages - and keepalives are all LMI messages.






31. Access Control Entry. An individual line in an ACL.






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






33. Web Cache Communication Protocol.






34. Flush timer.






35. Shaped round-robin.






36. An NTP mode in which an NTP host adjusts its clock in relation to an NTP server's clock.






37. A Cisco IOS queuing tool most notable for its reservation of a minimum bandwidth for each queue.






38. Ethernet MAC address that represents all devices on the LAN.






39. 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.






40. In Frame Relay - a link between a router and a Frame Relay switch.






41. WRED is a method of congestion avoidance that works by dropping packets before the output queue becomes completely full. WRED can base its dropping behavior on IP Precedence or DSCP values to drop low-priority packets before high-priority packets.






42. Another term for summary route.






43. Sequence number.






44. A generic term that refers to the data structure used by a layer in a layered network architecture when sending data.






45. A technology that sends a high-speed data stream over multiple subcarriers simultaneously. It is highly immune to multipath interference. 802.11a and 802.11g specify the use of OFDM.






46. Weighted tail drop.






47. A Cisco IOS queuing tool most notable for its scheduler - which always services the high-priority queue over all other queues.






48. A wireless LAN that includes the use of access points. Infrastructure mode connects wireless users to a wired network and allows wireless users to roam throughout a facility between different access points. All 802.11 data frames in an infrastructure






49. Differentiated Services Code Point.






50. A method for how a TCP sender grows its calculated CWND variable - thereby growing the allowed window for the connection. Congestion Avoidance grows CWND linearly.
