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. Link-State Refresh. A timer that determines how often the originating router should reflood an LSA - even if no changes have occurred to the LSA.






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






3. Rapid Spanning Tree Protocol.






4. A bit in the LAPF Frame Relay header that - when set to 1 - implies that the frame has experienced congestion.






5. On a serial cable - the pin lead set by the DCE to imply that the DCE is ready to signal using pin leads






6. With DiffServ - a DSCP marking and a related set of QoS actions applied to packets that have that marking.






7. The information maintained by a router for each multicast entry in its multicast routing table - such as incoming interface - outgoing interface list - Uptime timer - Expire timer - etc.






8. A type of spread spectrum that spreads RF signals over the frequency spectrum by transmitting the signal at different frequencies according to a hopping pattern. One of the original 802.11 physical layers used FHSS to offer data rates of 1 and 2 Mbps






9. A characterization of a BGP path attribute in which all BGP implementations must support and understand the attribute (well known) - and all BGP Updates must include the attribute (mandatory).






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






11. With EIGRP - for a particular route - the case in which the RD is lower than the FD.






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






13. A BGP router that forwards iBGP-learned routes to other iBGP routers.






14. A technology that enables frequency reuse. Two variants exist: frequency hopping (FHSS) and direct sequence (DSSS). Both techniques spread the signal power over a relatively wide portion of the frequency spectrum over time - to reduce interference be






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






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






17. Cisco IOS Embedded Event Manager - a feature that monitors events on a router and reports their results. Principally intended to increase availability - EEM provides flexible - granular detection and alerting functions.






18. The rate at which a shaper limits the bits exiting the shaper.






19. Local Management Interface.






20. Another name for Superframe.






21. 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.






22. The process of taking the payload inside a Layer 2 frame - including the headers of Layer 3 and above - compressing the data - and then uncompressing the data on the receiving router.






23. 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.






24. 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.






25. A term referring to the MQC service-policy command - which is used to enable a policy map on an interface.






26. Class of Service.






27. Digital subscriber line - a common Internet service type for residential and business customers.






28. Cisco IOS router feature by which a route map determines how to forward a packet - typically based on information in the packet other than the destination IP address.






29. The process of installing a multicast application; also referred to as launching an application.






30. A Cisco-proprietary protocol - used by LAN switches to communicate VLAN configuration.






31. A Layer 3 forwarding path through a router that does not optimize the forwarding path through the router.






32. Link Control Protocol.






33. An MQC configuration style by which one policy map calls a second policy map. For example - a shaping policy map can call an LLQ policy map to implement LLQ for packets shaped by CB Shaping.






34. A protocol used for reliable multicast and unicast transmissions. Used by EIGRP.






35. Aka network layer reachability information.






36. An issue whereby parts of the RF signal take different paths from the source to the destination - which causes direct and reflected signals to reach the receiver at different times - and corresponding bit errors.






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






38. 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.






39. Reported distance or Route Distinguisher.






40. Provider router.






41. 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.






42. An intrusion detection system that safeguards the wireless LAN from malicious and unauthorized access.






43. The specific frequency subband on which the radio card or access point is operating. The RF channel is set in the access point or ad hoc stations.






44. In IPv6 - the Neighbor Discovery message used by an IPv6 node to send information about itself to its neighbors.






45. In the context of SNMP - the Set command is sent by an SNMP manager - to an agent - requesting that the agent set a single identified variable to the stated value. The main purpose is to allow remote configuration and remote operation - such as shutt






46. An optional nontransitive BGP path attribute that lists the route reflector cluster IDs through which a route has been advertised - as part of a loop-prevention process similar to the AS_PATH attribute.






47. High Density Binary 3.






48. A set of four hex digits listed in an IPv6 address. Each quartet is separated by a colon.






49. A WRED process by which WRED does not discard packets during times in which a queue's minimum threshold has not been passed.






50. The RMON function of tracking a particular variable. RMON events trigger RMON alarms.
