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. Modular QoS CLI.






2. DCE devices are one of two devices on either end of a communications circuit - specifically the device with more control over the communications. Frame Relay switches are DCE devices. DCEs are also known as data circuit-terminating equipment (DTE).






3. 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.






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






5. A type of logic for how a router uses a default route. When a default route exists - and the class A - B - or C network for the destination IP address does not exist in the routing table - the default route is used. If any part of that classful netwo






6. A BGP path attribute that implies how the route was originally injected into some router's BGP table.






7. The All OSPF DR Routers multicast IP address - listened for by DR and BDR routers.






8. Finish time.






9. A term referring to the process of applying the Message Digest 5 (MD5) algorithm to a string - resulting in another value. The original string cannot be easily computed even when the hash is known - making this process a strong method for storing pas






10. A serial-line encoding standard like B8ZS - but with each set of four consecutive 0s being changed to include a Bipolar Violation to maintain synchronization.






11. A Cisco IOS feature that provides reporting information to a NetFlow aggregator based on traffic flows.






12. A method of collecting traffic received on a switch port or a VLAN and sending it to specific destination ports on the same switch.






13. The password required by the enable command. Also - this term may specifically refer to the password defined by the enable password command.






14. Weighted tail drop.






15. Receiver's advertised window.






16. Customer edge.






17. Ethernet process by which devices attached to the same cable negotiate their speed and the duplex settings over the cable.






18. In the PIM-SM design - the central distribution point to which the multicast traffic is first delivered from the source designated router.






19. A TCP variable used as the basis for a TCP sender's timer defining how long it should wait for a missing acknowledgement before resending the data.






20. A term referring to how a router views a BGP peer relationship - in which the peer is in another AS.






21. The process of forwarding packets through a router. Also call IP routing.






22. A security standard that includes both TKIP and AES and was ratified by the Wi-Fi Alliance.






23. The original standardized set of generic SNMP MIB variables - defined in RFC 1158.






24. A type of OSPF stub area that - unlike stub areas - can inject external routes into the NSSA area.






25. Data-link connection identifier.






26. A routing protocol feature by which the routing update includes the entire set of routes - even if some or all of the routes are unchanged.






27. A standard (RFC 951) protocol by which a LAN-attached host can dynamically broadcast a request for a server to assign it an IP address - along with other configuration settings - including a subnet mask and default gateway IP address.






28. Digital Signal Level 0.






29. An exterior routing protocol designed to exchange prefix information between different autonomous systems. The information includes a rich set of characteristics called path attributes - which in turn allows for great flexibility regarding routing ch






30. A BGP message that includes withdrawn routes - path attributes - and NLRI.






31. The two computers use a protocol with which to communicate with the same layer on another computer. The protocol defined by each layer uses a header that is transmitted between the computers to communicate what each computer wants to do.






32. A message sent by a multicast router - by default every 125 seconds - on each of its LAN interfaces to determine whether any host wants to receive multicast traffic for any group.






33. Label switched path.






34. A name used for DS3 lines inside the North American TDM hierarchy.






35. Maximum transmission unit.






36. A 16-bit number set with a router config-register command. It is used to set several low-level features related mainly to accessing the router and what the router does when powered on.






37. Regeneration of the Layer 2 encapsulation removed from frames forwarded in a SPAN session.






38. 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.






39. 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.






40. Dynamic Trunking Protocol.






41. With EIGRP - the metric (distance) of a route as reported by a neighboring router.






42. A Cisco IOS queuing tool that uses MQC configuration commands - reserves a minimum bandwidth for some queues - provides high-priority scheduling for some queues - and polices those queues to prevent starvation of lower-priority queues during interfac






43. The first 4 bits of the first octet must be 1110. The last 28 bits are unstructured.






44. 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.






45. High Density Binary 3.






46. A network/subnet to which only one OSPF router is connected.






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






48. A serial-line encoding standard that sends alternating positive and negative 3-volt signals for binary 1 - and no signal (0 V) for binary 0.






49. An IPv6 address format used for publicly registered IPv6 addresses.






50. A name used for DS3 lines inside the European TDM hierarchy.
