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. The data structure used by OSPF to hold LSAs.






2. This term has two BGP-related definitions. First - it is the normal process in which a router - before sending an Update to an eBGP peer - adds its local ASN to the beginning of the AS_PATH path attribute. Second - it is the routing policy of purpose






3. Router Advertisement.






4. A process whereby a switch - when making a forwarding decision - uses not only Layer 2 logic but other OSI layer equivalents as well.






5. Cisco Wireless LAN Solution Engine.






6. A Cisco 12000 series router feature that combines the key features of LLQ and CQ to provide similar congestion-management features.






7. A single label and link that is part of a complete LDP. See also label switched path.






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






9. An address type in IPv6 networks that is used only on the local link and never beyond that scope.






10. A wireless LAN that offers connections to the Internet from public places - such as airports - hotels - and coffee shops.






11. The underlying algorithms associated with RIP.






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






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






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






15. Aka minimum CIR.






16. An IOS feature in which multiple routing tables and routing forwarding instances exist in a single router - with interfaces being assigned to one of the several VRFs. This feature allows separating of routing domains inside a single router platform.






17. Data communications equipment.






18. The IPv6 protocol used for the discovery of which hosts are listening for which multicast IP addresses for IPv6.






19. 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






20. The list of entries learned by the switch DHCP snooping feature. The entries include the MAC address used as the device's DHCP client address - the assigned IP address - the VLAN - and the switch port on which the DHCP assignment messages flowed.






21. Request-to-send/clear-to-send.






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






23. A router that is not an ABR or ASBR in that all of its interfaces connect to only a single OSPF area.






24. 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.






25. CDP Control Protocol.






26. Not-so-stubby area.






27. 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.






28. An Internet standard authentication protocol that uses clear-text passwords and a two-way handshake to perform authentication over a PPP link.






29. 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.






30. A Frame Relay traffic shaping feature during which the shaping rate is reduced when the shaper notices congestion through the receipt of BECN or ForeSight messages.






31. A CBWFQ and LLQ term referring to the bandwidth on an interface that is neither reserved nor allocated via a priority command.






32. A packet-scheduling algorithm used in Cisco switches that provides similar behavior to CBWFQ in shared mode and polices in shaped mode.






33. Multilayer Switching.






34. A table used by CEF that holds information about adjacent IP hosts to which packets can be forwarded.






35. Defined in IEEE 802.1d - a protocol used on LAN bridges and switches to dynamically define a logical network topology that allows all devices to be reached - but prevents the formation of loops.






36. With Spanning Tree Protocol - the single port on each LAN segment from which the best Hello BPDU is forwarded.






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 definitions for a particular set of data variables - with those definitions following the SMI specifications. See also SMI.






39. Sending a message from a single source or multiple sources to selected multiple destinations across a Layer 3 network in one data stream.






40. The Cisco IOS Router IP Traffic Export feature - intended for intrusion detection - exports IP traffic that has signs of an attack - such as duplicate IP packets simultaneously received on two or more of a router's interfaces.






41. Designated router.






42. An FRF standard for payload compression.






43. Cisco IOS IP Service Level Agent feature. Provides for router-generated information useful for verifying network performance on a scheduled basis - and the associated reporting functions.






44. The original MPLS protocol used to advertise the binding (mapping) information about each particular IP prefix and associated label. It is slightly different from LDP - but functionally equivalent. See also LDP.






45. Cell Loss Priority.






46. The number of beacons that governs how often multicast frames are sent over a wireless LAN.






47. In BGP - a feature in which BGP routes cannot be considered to be a best route to reach an NLRI unless that same prefix exists in the router's IP routing table as learned via some IGP.






48. Common Spanning Tree.






49. A calculation of the length of the AS_PATH PA - which includes 1 for each number in the AS_SEQ - 1 for an entire AS_SET segment - and possibly other considerations.






50. The MD5-encoded password defined by the enable secret command.
