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 commonly used name for Multi-VRF CE.






2. Static length subnet masking.






3. Copper cable with RJ-45 connectors in which the wire at pin 1 on one end is connected to pin 1 on the other end; the wire at pin 2 is connected to pin 2 on the other end; and so on.






4. 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






5. A Cisco IOS configuration tool that can be used to match routing updates based on a base network address - a prefix - and a range of possible masks used inside the values defined by the base network address and prefix.






6. A vendor consortium that formerly worked to further Frame Relay common vendor standards.






7. Local Management Interface.






8. In IP routing - a term referring to the building of IP routing tables by IP routing protocols.






9. 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.






10. An early T1 framing standard.






11. In SNMP - the process of a manager using successive GetNext and GetBulk commands to discover the exact MIB structure supported by an SNMP agent. The process involves the manager asking for each successive MIB leaf variable.






12. Flush timer.






13. The data structure used by OSPF to hold LSAs.






14. 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.






15. Challenge Handshake Authentication Protocol.






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






17. 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.






18. The All OSPF Routers multicast IP address - listened for by all OSPF routers.






19. Password Authentication Protocol.






20. Modular QoS CLI.






21. A WFQ term referring to its drop logic - which is similar to tail-drop behavior.






22. Alternate name for the SPF algorithm - named for its inventor - Edsger W. Dijkstra.






23. An enhanced version of WEP that is part of the 802.11i standard and has an automatic key-update mechanism that makes it much more secure than WEP. TKIP is not as strong as AES in terms of data protection.






24. In IPv6 - an address used in the Neighbor Discovery (ND) process. The format for these addresses is FF02::1:FF00:0000/104 - and each IPv6 host must join the corresponding group for each of its unicast and anycast addresses.






25. 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.






26. A 3-bit field in an 802.1Q header used for marking frames.






27. A prestandard (at the time of publication) wireless LAN physical layer that offers data rates in the hundreds of megabits per second.






28. 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.






29. A message sent by each host - either in response to a router query or on its own - to all multicast groups for which it would like to receive multicast traffic. The destination address on the Report is 224.0.0.22 - and a host can specify the source a






30. A message sent by the multicast router - by default every 60 seconds - on each of its LAN interfaces to determine whether any host wants to receive multicast traffic for any group.






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






32. A BGP process by which a router reapplies routing policy configuration (route maps - filters - and the like) based on stored copies of sent and received BGP Updates.






33. Peak information rate.






34. A BGP feature by which a router learns iBGP routes - and then forwards them to other iBGP peers - reducing the required number of iBGP peers while also avoiding routing loops.






35. Policing in which a single rate is metered - and packets are placed into one of two categories (conform or exceed).






36. Provider edge.






37. A method that creates three thresholds per egress queue in the Cisco 3560 switch. Traffic is divided into the three queues based on CoS value - and given different likelihoods (weight) for tail drop when congestion occurs based on which egress queue






38. An EIGRP message that is used to ask neighboring routers to verify their route to a particular subnet. Query messages require an Ack.






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






40. A Cisco-proprietary feature. After a Cisco multicast router receives IGMP Join or Leave messages from hosts - it communicates to the connected Cisco switches - telling them which hosts (based on their unicast MAC addresses) have joined or left each m






41. Rendezvous point.






42. Internal BGP.






43. Alarm Indication Signal. With T1s - the practice of sending all binary 1s on the line in reaction to problems - to provide signal transitions and allow recovery of synchronization and framing.






44. A characterization of a network attack in which packets flow to the attacker - and then out to the true recipient. As a result - the user continues to send data - increasing the chance that the attacker learns more and better information.






45. An integer setting for EIGRP and IGRP. Any FS route whose metric is less than this variance multiplier times the successor's metric is added to the routing table - within the restrictions of the maximum-paths command.






46. Link Fragmentation and Interleaving.






47. A term used in this book to refer to a route that is included in a larger summary route.






48. Designed to solve the problems of multicast duplication and multicast routing loops. For every multicast packet received - a multicast router examines its source IP address - consults its unicast routing table - determines which interface it would us






49. 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






50. An 802.11 frame that access points or stations in ad hoc networks send periodically so that wireless stations can discover the presence of a wireless LAN and coordinate use of certain protocols - such as power-save mode.
