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. An alternative software loaded into a Cisco router - used for basic IP connectivity; most useful when Flash memory is broken and you need IP connectivity to copy a new IOS image into Flash memory.






2. A type of AS_PATH segment consisting of an unordered list of ASNs consolidated from component subnets of a summary BGP route.






3. 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.






4. A 3-bit field in the first 3 bits of the ToS byte in the IP header - used for QoS marking.






5. The router in a VRRP group that is currently actively forwarding IP packets. Conceptually the same as an HSRP Active router.






6. 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.






7. Structure of Management Information.






8. A multicast routing protocol whose default action is to flood multicast packets throughout a network.






9. Multicast Open Shortest Path First.






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






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






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






13. 64 bits at the end of an IPv6 global address - used to uniquely identify each host in a subnet.






14. Prefix list.






15. Data terminal equipment.






16. Each 802.11 station passively monitors each RF channel for a specific amount of time and listens for beacons. Stations use the signal strengths of found beacons to determine the access point or ad hoc network with which to attempt association.






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






18. An FRF standard for Frame Relay-to-ATM Service Interworking in which one DTE uses Frame Relay and one uses ATM.






19. Neighbor Advertisement.






20. A T1 alarm state that occurs when the receiver can no longer consistently identify the frame. See LOF.






21. Typically used by protocols that perform flow control (like TCP) - a TCP window is the number of bytes that a sender can send before it must pause and wait for an acknowledgement of some of the yet-unacknowledged data.






22. In MQC and CB Policing - a configuration style by which - for one category of packets (conform - exceed - or violate) - more than one marking action is defined for a single category. For example - marking DSCP and DE.






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






24. Link Aggregation Control Protocol.






25. Label Forwarding Information Base.






26. A type of OSPF packet used to exchange and acknowledge LSA headers. Sometimes called DBD.






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






28. An MPLS LSR that can forward and receive both labeled and unlabeled packets.






29. Per-Hop Behavior.






30. Source-specific multicast.






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






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






33. Each 802.11 station periodically sends a probe request frame on each RF channel and monitors probe response frames that all access points within range send back. Stations use the signal strength of the probe response frames to determine which access






34. Jargon used by STP mostly when discussing the root election process; refers to a Hello with a lower bridge ID. Sometimes refers to a Hello with the same bridge ID as another - but with better values for the tiebreakers in the election process.






35. Classless interdomain routing.






36. Allows the router to act as an inline IPS - doing deep packet inspection.






37. Virtual Routing and Forwarding table.






38. A 3-tuple consisting of an IP address - port number - and transport layer protocol. TCP connections exist between a pair of sockets.






39. Cisco-proprietary STP feature in which a switch port monitors for incoming superior Hellos - and reacts to a superior Hello to prevent any switch connected to that port from becoming root.






40. An OSPF external route for which internal OSPF cost is not added to the cost of the route as it was redistributed into OSPF.






41. Differentiated Services.






42. A Cisco-proprietary Layer 2 protocol that enables a router to communicate to a switch which multicast group traffic the router does and does not want to receive from the switch.






43. Exterior Gateway Protocol.






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






45. IP multicast address range from 224.0.0.0 through 239.255.255.255.






46. An SPF calculation for which a router does not need to run SPF for any LSAs inside its area - but instead runs a very simple algorithm for changes to LSAs outside its own area.






47. An optimized Layer 3 forwarding path through a router. Fast switching optimizes routing table lookup by creating a special - easily searched table of known flows between hosts.






48. A T1 alarm state that occurs when a device has detected a local LOF/LOS/AIS condition. The device in Red alarm state then sends a Yellow alarm signal.






49. Dynamic Trunking Protocol.






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