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 Cisco-proprietary messaging protocol implemented in WAN switches that can be used to signal network status - including congestion - independent of end-user frames and cells.






2. Source-specific multicast.






3. Used by WRED to calculate the rate at which the average queue depth changes as compared with the current queue depth. The larger the number - the slower the change in the average queue depth.






4. With RIP - a per-route timer - which is reset and grows with the Invalid timer. When the Flush timer mark is reached (default 240 seconds) - the router removes the route from the routing table - and now accepts any other routes about the failed subne






5. A type of OSPF packet used to acknowledge LSU packets.






6. 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.






7. In IPv6 - the Neighbor Discovery message used by an IPv6 node to send information about itself to its neighbors.






8. A characterization of a BGP path attribute in which all BGP implementations must support and understand the attribute (well known) - but BGP Updates can either include the attribute or not depending on whether a related feature has been configured (d






9. A reserved value for the BGP COMMUNITY path attribute that implies that the route should not be advertised to any other peer.






10. Port Aggregation Protocol.






11. 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






12. An IPv6/IPv4 tunneling method that is designed for transporting IPv6 packets within a site where a native IPv6 infrastructures is not available.






13. A security standard that includes both TKIP and AES and was ratified by the Wi-Fi Alliance.






14. Class-Based Weighted Fair Queuing.






15. A set of all devices that receive broadcast frames originating from any device within the set. Devices in the same VLAN are in the same broadcast domain.






16. Jargon referring to the minimum value to which adaptive shaping will lower the shaping rate.






17. Frame Relay Forum.






18. A term relating to Cisco LAN switch tail-drop logic - in which multiple tail-drop thresholds may be assigned based on CoS or DSCP - resulting in some frames being discarded more aggressively than others.






19. A bit inside the Frame Relay header that - when set - implies that congestion occurred in the direction opposite (or backward) as compared with the direction of the frame.






20. An FRF standard for LFI for VoFR (FRF.11) VCs - in which all voice frames are interleaved in front of data frames' fragments.






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






22. In MPLS - the mapping of an IP prefix and a label - which is then advertised to neighbors using LDP.






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






24. Regeneration of the Layer 2 encapsulation removed from frames forwarded in a SPAN session.






25. Multilayer Switching.






26. Sent by a PIM-DM or PIM-SM router when it receives a multicast packet for a group on a LAN interface that is in the outgoing interface list for the group; includes the administrative distance of the unicast routing protocol used to learn the network






27. Dynamic Host Configuration Protocol.






28. Access Control Server. A term referring generically to a server that performs many AAA functions. It also refers to the software product Cisco Secure Access Control Server.






29. A route that is used for forwarding packets when the packet does not match any more specific routes in the IP routing table.






30. Sequence number.






31. An optimized Layer 3 forwarding path through a router or switch. CEF optimizes routing table lookup by creating a special - easily searched tree structure based on the contents of the IP routing table. The forwarding information is called the Forward






32. Jargon referring to any queue that receives priority service - often used for queues in an LLQ configuration that have the priority command configured.






33. Controls the distribution of multicast traffic for the private multicast address range 239.0.0.0 to 239.255.255.255 by configuring a filter and applying it on the interfaces.






34. Route Target.






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






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






37. A set of all devices for which any frame sent by one of the devices would collide with any frames transmitted at the same time by any of the other devices in the set.






38. The first 4 bits of the first octet must be 1110. The last 28 bits are unstructured.






39. The process of running the SPF algorithm against the LSDB - with the result being the determination of the current best route(s) to each subnet.






40. A set of DiffServ PHBs that defines 12 DSCP values - with four queuing classes and three drop probabilities within each queuing class.






41. A definition that determines the data structure and information implied by a particular LSA.






42. An enhanced version of T1 framing - as compared with the earlier Superframe (D4) standard.






43. Smoothed Round-Trip Time.






44. Operation - Administration - and Maintenance.






45. The process by which neighboring OSPF routers examine their Hello messages and elect the DR. The decision is based on priority (highest) - or RID (highest) if priority is a tie.






46. A bit in the Frame Relay header that - when set to 1 - means that if a device needs to discard frames - it should discard the frames with DE 1 first.






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






48. Time to Live.






49. Virtual circuit.






50. Extended Superframe.
