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






2. A conceptual model used by CB Policing when using an excess burst.






3. Dynamic Multipoint VPN.






4. A term referring to the MQC class-map command and its related subcommands - which are used for classifying packets.






5. With EIGRP - the metric value for the lowest-metric route to a particular subnet.






6. A queue created by Cisco IOS as a result of the configuration of a queuing tool.






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






8. A BGP feature that overcomes the requirement of a full mesh of iBGP peers inside a single AS by separating the AS into multiple sub-autonomous systems.






9. Controls the distribution of multicast traffic by checking the TTL values configured on the interfaces. It forwards the multicast packet only on those interfaces whose configured TTL value is less than or equal to the TTL value of the multicast packe






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






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






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. A set of rules by which BGP examines the details of multiple BGP routes for the same NLRI and chooses the single best BGP route to install in the local BGP table.






14. A strategy for subnetting a classful network for which masks/prefixes are different for some subnets of that one classful network.






15. Each 802.11 station periodically sends a probe request frame on each RF channel and monitors probe response frames that all access points within range send back. Stations use the signal strength of the probe response frames to determine which access






16. Reverse ARP.






17. In OSPF - a number assigned to each LSA - ranging from 0x80000001 and wrapping back around to 0x7FFFFFFF - which is used to determine which LSA is most recent.






18. A standard (RFC 903) protocol by which a LAN-attached host can dynamically broadcast a request for a server to assign it an IP address. See also ARP.






19. With PIM on a multiaccess network - the PIM router with the highest IP address on the subnet. It is also the IGMPv1 Querier. The DR is responsible for the following tasks: - Sending PIM register and PIM join and prune messages toward the RP to infor






20. From a Layer 1 perspective - the process of using special strings of electrical signals over a transmission medium to inform the receiver as to which bits are overhead bits - and which fit into individual subchannels.






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






22. Time-division multiplexing.






23. WRED compares this setting to the average queue depth to decide whether packets should be discarded. All packets are discarded if the average queue depth rises above this maximum threshold.






24. Another name for Superframe.






25. Discard Eligible.






26. Digital Signal Level 1.






27. Reported distance or Route Distinguisher.






28. A routing protocol feature by which the routing update includes only routes that have changed - rather than include the entire set of routes.






29. Version 6 of the IP protocol - which uses 128-bit IP addresses.






30. Time Interval.






31. Out of Frame.






32. An IPv6 address type that is used by a number of hosts in a network that are providing the same service. Hosts accessing the service are routed to the nearest host in an anycast environment based on routing protocol metrics.






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






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






35. A wireless LAN physical layer that operates at up to 54-Mbps data rates using OFDM in the 5-GHz band.






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






37. Similar to an appliance firewall - in that interfaces are placed into security zones. Traffic is allowed between interfaces in the same zone. You can apply policies to filter and control traffic between zones.






38. The range 233.0.0.0 through 233.255.255.255 that IANA has reserved (RFC 2770) on an experimental basis. It can be used by anyone who owns a registered autonomous system number to create 256 global multicast addresses.






39. A list of interspersed alphanumeric literals and metacharacters that are used to apply complex matching logic to alphanumeric strings. Often used for matching AS_PATHs in Cisco routers.






40. Link Aggregation Control Protocol.






41. Instead of advertising all routes out a particular interface - the routing protocol omits the routes whose outgoing interface field matches the interface out which the update would be sent.






42. Type of Service byte.






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






44. The multicast IP address 224.0.0.5 - listened for by all OSPF routers.






45. The condition in which a route has been in an EIGRP active state for longer than the router's Active timer.






46. A designated router that is directly connected with a source of the multicast group.






47. Often used synonymously with neighbor - but with emphasis on the fact that all required parameters match - allowing routing updates to be exchanged between the routers.






48. An STP timer that dictates how long a switch should wait when it ceases to hear Hellos.






49. Differentiated Services.






50. Refers to how a router views a BGP peer relationship - in which the peer is in the same AS.
