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. When subnetting a class A - B - or C address - the subnet for which all subnet bits are binary 1.






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






3. A Cisco-proprietary messaging protocol used to negotiate the dynamic creation of PortChannels (EtherChannels) and to choose which ports can be placed into an EtherChannel.






4. 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.






5. An E-LSR in an MPLS VPN network whose role in a particular discussion is to receive unlabeled packets over customer links and then forward the packets as labeled packets into the MPLS network.






6. Management Information Base.






7. A message sent by a host when it wants to leave a group - addressed to the All Multicast Routers address 224.0.0.2.






8. 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.






9. An IEEE standard that - when used with EAP - provides user authentication before their connected switch port allows the device to fully use the LAN.






10. An IP variable that defines the largest size allowed in an IP packet - including the IP header. IP hosts must support an MTU of at least 576 bytes.






11. On a serial cable - the pin lead set by the DTE to tell the DCE that the DTE wants to send data.






12. An 802.1d STP port state in which the port has been administratively disabled.






13. Data-link connection identifier.






14. 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.






15. 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.






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






17. Generic routing encapsulation.






18. The process of running the SPF algorithm against the LSDB - with the result being the determination of the current best route(s) to each subnet.






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






20. Modular QoS CLI.






21. Multicast Open Shortest Path First.






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






23. An MPLS VPN term referring to any LSR that connects to customers to support the forwarding of unlabeled packets - as well as connecting to the MPLS network to support labeled packets - thereby making the LSR be on the edge between the provider and th






24. Diffusing Update Algorithm.






25. The portion of PPP focused on features that are unrelated to any specific Layer 3 protocol.






26. The process of breaking a frame into pieces - sending some of the fragments - and then sending all or part of a different packet - all of which is done to reduce the delay of the second packet.






27. Provides dynamic inspection of traffic as it traverses the router. It uses Context-Based Access Control (CBAC) to look deeper into a packet than an access list can. It tracks outbound traffic and dynamically allows in responses to that traffic.






28. The protocol used in IPv6 for many functions - including address autoconfiguration - duplicate address detection - router - neighbor - and prefix discovery - neighbor address resolution - and parameter discovery.






29. An MPLS term referring to the MPLS label just before the IP header. Also called the VPN label when implementing MPLS VPNs.






30. The rate at which a policer limits the bits exiting or entering the policer.






31. Hot Standby Router Protocol.






32. A type of OSPF packet used to discover neighbors - check for parameter agreement - and monitor the health of another router.






33. Defined in IEEE 802.1AD - defines a messaging protocol used to negotiate the dynamic creation of PortChannels (EtherChannels) and to choose which ports can be placed into an EtherChannel.






34. An architecture and set of documents that defines Cisco's best recommendations for how to secure a network.






35. Network Time Protocol.






36. Ethernet MAC address that represents a single NIC or interface.






37. A routing protocol feature for which the routing protocol sends routing updates immediately upon hearing about a changed route - even though it may normally only send updates on a regular update interval.






38. A message sent by a router - after receiving a Leave message from a host - to determine whether there are still any active members of the group. The router uses the group address as the destination address.






39. 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






40. Jargon used to refer to the second of two buckets in the dual token bucket model; its size is Be.






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. When subnetting a class A - B - or C address - the subnet for which all subnet bits are binary 0.






43. Clear To Send.






44. Calculated measurement based on the actual queue depth and the previous average. Designed to allow WRED to adjust slowly to rapid changes of the actual queue depth.






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






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






47. A BGP router in an AS that uses route reflectors - but that is not aided by any RR server.






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






49. RFC 1918-defined IPv4 network numbers that are not assigned as public IP address ranges - and are not routable on the Internet. Intended for use inside enterprise networks.






50. A communication protocol between hosts and a multicast router by which routers learn of which multicast groups' packets need to be forwarded onto a LAN.
