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 method for how a TCP sender grows its calculated CWND variable - thereby growing the allowed window for the connection. Slow Start grows CWND at an exponential rate.






2. A category used by a policer to classify packets relative to the traffic contract. With two-color policers - these packets are considered to be above the contract; for three-color - these packets are above the Bc setting - but within the Be setting.






3. The IEEE standardized protocol for VLAN trunking.






4. An OSPF timer that determines how long an LSA can remain in the LSDB without having heard a reflooded copy of the LSA.






5. With OSPF - the OSPF router that wins an election amongst all current neighbors. The DR is responsible for flooding on the subnet - and for creating and flooding the type 2 LSA for the subnet.






6. Link Access Procedure for Frame-Mode Bearer Services.






7. An NTP mode in which two or more NTP servers mutually synchronize their clocks.






8. Voice over Frame Relay.






9. An MQC-based feature of IOS that is used to classify and mark packets for QoS purposes.






10. A mechanism that counters collisions caused by hidden nodes. If enabled - the station or access point must first send an RTS frame and receive a CTS frame before sending each data frame.






11. In IPv6 - the Neighbor Discovery message used by an IPv6 node to request information about a neighbor or neighbors.






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






13. Time Interval.






14. An EIGRP message that is used to acknowledge reliable EIGRP messages - namely Update - Query - and Reply messages. Acks do not require an Ack.






15. Defined in RFC 826 - a protocol used on LANs so that an IP host can discover the MAC address of another device that is using a particular IP address.






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






17. A route that is created to represent one or more smaller component routes - typically in an effort to reduce the size of routing and topology tables.






18. A configuration tool in Cisco IOS that allows basic programming logic to be applied to a set of items. Often used for decisions about what routes to redistribute - and for setting particular characteristics of those routes






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






20. An MPLS VPN term referring to a router at a customer site that does not implement MPLS.






21. Extended Superframe.






22. Used to reserve network resources for a flow as it traverses the network. A device that creates an RSVP reservation guarantees that it can provide the bandwidth - latency - or other resources that are requested by RSVP.






23. A time value that each wireless station must set based on the duration value found in every 802.11 frame. The time value counts down and must be equal to zero before a station is allowed to access the wireless medium. The result is a collision-avoida






24. 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.






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






26. Maximum Segment Size.






27. Cisco IOS Embedded Event Manager - a feature that monitors events on a router and reports their results. Principally intended to increase availability - EEM provides flexible - granular detection and alerting functions.






28. With EIGRP - a route that is not a successor route - but that meets the feasibility condition; can be used when the successor route fails - without causing loops.






29. Sequence number.






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






31. A neighbor state that signifies the other router has reached neighbor status - having passed the parameter check.






32. From one perspective - DTE devices are one of two devices on either end of a communications circuit - specifically the device with less control over the communications. In Frame Relay - routers connected to a Frame Relay access link are DTE devices.






33. An attack similar to a smurf attack - but using packets for the UDP Echo application instead of ICMP.






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. Each 802.11 station passively monitors each RF channel for a specific amount of time and listens for beacons. Stations use the signal strengths of found beacons to determine the access point or ad hoc network with which to attempt association.






36. Class of Service.






37. 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






38. Any routing protocol that uses the concept of using the SPF algorithm with an LSDB to compute routes.






39. AS number. 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.






40. Data Set Ready.






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






42. Network Address Translation.






43. 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.






44. With EIGRP - the route to each destination for which the metric is the lowest of all known routes to that network.






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






46. Point-to-Point Protocol.






47. Layer x PDU.






48. An FRF standard for Frame Relay-to-ATM Service Interworking in which both DTEs use Frame Relay - with ATM in between.






49. Loss of Signal. A T1 alarm state that occurs when the receiver has not received any pulses of either polarity for a defined time period.






50. A table inside a router that holds the path attributes and NLRI known by the BGP implementation on that router.
