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 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.






2. Modular QoS CLI.






3. A type of OSPF stub 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 cannot be injected into a totally stubby area.






4. The destination VLAN for an RSPAN session.






5. An individual line in an ACL.






6. Wired Equivalent Privacy.






7. Any OSPF neighbor for which the database flooding process has completed.






8. Receiver's advertised window.






9. A BGP router that - unknown to it - is aided by a route reflector server to cause all iBGP routers in an AS to learn all eBGP-learned prefixes.






10. 16 bits between the interface ID and global routing prefix in an IPv6 global address - used for subnet assignment inside an enterprise.






11. 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.






12. 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.






13. The rate at which a shaper limits the bits exiting the shaper.






14. A BGP path attribute that allows routers in one AS to set a value and advertise it into a neighboring AS - impacting the decision process in that neighboring AS. A smaller value is considered better. Also called the BGP metric.






15. Slow Start Threshold.






16. 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.






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






18. Used by RRs to denote the RID of the iBGP neighbor that injected the NLRI into the AS.






19. Port Aggregation Protocol.






20. An EIGRP message that informs neighbors about routing information. Update messages require an Ack.






21. The combination of PVST+ and Rapid Spanning Tree. It provides subsecond convergence time and is compatible with PVST+ and MSTP.






22. In an IOS confederation configuration - the actual ASN as seen by eBGP peers.






23. With EIGRP - a timer started when a reliable (to be acknowledged) message is transmitted. For any neighbor(s) failing to respond in its RTO - the RTP protocol causes retransmission. RTO is calculated based on SRTT.






24. The single port on each nonroot switch upon which the best Hello BPDU is received.






25. 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.






26. With RIP - the advertisement of a poisoned route out an interface - when that route was formerly not advertised out that interface due to split horizon rules.






27. Another term for summary route.






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






29. The PDU used by a particular layer of a networking model - with x defining the layer.






30. An MPLS data structure used for forwarding labeled packets. The LFIB lists the incoming label - which is compared to the incoming packet's label - along with forwarding instructions for the packet.






31. The algorithm used by OSPF and IS-IS to compute routes based on the LSDB.






32. An OSPF external route for which internal OSPF cost is added to the cost of the route as it was redistributed into OSPF.






33. Out of Frame.






34. Enables a wireless client to securely roam between access points in the same subnet or between subnets with access point handoff times within 50 ms.






35. Sent by a PIM router - by default every 30 seconds - on every interface on which PIM is configured to discover neighbors - establish adjacency - and maintain adjacency.






36. Receivers subscribe to an (S -G) channel when they request to join a multicast group. That is - they specify the unicast IP address of their multicast source and the group multicast address. SSM is typically used in very large multicast deployments s






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. EIGRP (and IGRP) allows for the use of bandwidth - load - delay - MTU - and link reliability; the K values refer to an integer constant that includes these five possible metric components. Only bandwidth and delay are used by default - to minimize re






39. A Cisco switch feature that allows separation of ports as if they were in separate VLANs - while allowing the use of a single IP subnet for all ports.






40. Link-state advertisement.






41. A characterization of a BGP path attribute in which all BGP implementations must support and understand the attribute (well known) - and all BGP Updates must include the attribute (mandatory).






42. Provider router.






43. 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.






44. Timer An STP timer that dictates how long a port should stay in the listening state and the learning state.






45. Protocol data unit.






46. Database Description.






47. Source-specific multicast.






48. When subnetting a class A - B - or C address - the subnet for which all subnet bits are binary 0.






49. A BGP router in an AS that uses route reflectors - but that is not aided by any RR server.






50. Quantum value.
