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






2. With RIP - the regular interval at which updates are sent. Each interface uses an independent timer - defaulting to 30 seconds.






3. Forwarding Information Base.






4. Digital Signal Level 0.






5. A component that interfaces with a phone using IP and provides connections to the Public Switched Telephone Network (PSTN).






6. Authentication - authorization - and accounting.






7. Management Information Base.






8. 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.






9. Any occurrence that could change a router's EIGRP topology table - including a received Update or Query - a failed interface - or the loss of a neighbor.






10. In 802.1X - the computer that stores usernames/passwords and verifies that the correct values were submitted before authenticating the user.






11. Defined in RFC 1293 - this protocol allows a Frame Relay-attached device to react to a received LMI "PVC up" message by announcing its Layer 3 addresses to the device on the other end of the PVC.






12. A name used for DS1 lines inside the North American TDM hierarchy.






13. A conceptual model used by shapers and policers to represent their internal logic.






14. A Cisco IOS configuration tool - using the ip as-path access-list command - that defines a list of statements that match the AS_PATH BGP path attribute using regular expressions.






15. Time Interval.






16. A router that is allowed to receive a packet from an OSPF router and then forward the packet to another OSPF router.






17. Class of Service.






18. Classless interdomain routing.






19. Provider edge.






20. A wireless LAN that includes the use of access points. Infrastructure mode connects wireless users to a wired network and allows wireless users to roam throughout a facility between different access points. All 802.11 data frames in an infrastructure






21. A characterization of a network attack in which packets flow to the attacker - and then out to the true recipient. As a result - the user continues to send data - increasing the chance that the attacker learns more and better information.






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






23. The MPLS feature by which an ingress E-LSR copies the IP packet's IP TTL field into the MPLS header's TTL field.






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






25. 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






26. A possible side effect of a scheduler that performs strict-priority scheduling of a queue - which can result in lower-priority queues getting little or no service.






27. The process by which neighboring OSPF routers examine their Hello messages and elect the DR. The decision is based on priority (highest) - or RID (highest) if priority is a tie.






28. A BGP path attribute that is communicated throughout a single AS to signify which route of multiple possible routes is the best route to be taken when leaving that AS. A larger value is considered to be better.






29. A term referring to EIGRP's internal processing logic.






30. The process of forwarding packets through a router. Also called IP forwarding.






31. As defined in RFCs 2765 and 2766 - a method of translating between IPv4 and IPv6 that removes the need for hosts to run dual protocol stacks. NAT-PT is an alternative to tunneling IPv6 over an IPv4 network - or vice versa.






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






33. An SPF calculation as a result of changes inside the same area as a router - for which the SPF run must examine the full LSDB.






34. One of the two modes of MDRR - in which the priority queue is serviced between each servicing of the non-priority queues.






35. Port Address Translation.






36. 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.






37. Another term for summary route.






38. In the context of SNMP - the Inform command is sent by an SNMP manager to communicate a set of variables - and their values - to another SNMP manager. The main purpose is to allow multiple managers to exchange MIB information - and work together - wi






39. Bipolar Violation.






40. A BGP ASN whose value is between 64 -512 and 65 -535. These values are not assigned for use on the Internet - and can be used for private purposes - typically either within confederations or by ISPs to hide the ASN used by some customers.






41. An EIGRP message that is used by neighbors to reply to a query. Reply messages require an Ack.






42. 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.






43. An attack by which the attacker initiates many TCP connections to a server - but does not complete the TCP connections - by simply not sending the third segment normally used to establish the connection. The server may consume resources and reject ne






44. A characteristic of OSPF interfaces that determines whether a DR election is attempted - whether or not neighbors must be statically configured - and the default Hello and Dead timer settings.






45. Another name for Superframe.






46. A term used with WFQ for the number assigned to a packet as it is enqueued into a WFQ queue. WFQ schedules the currently lowest FT packet next.






47. A protocol - defined in RFC 2865 - that defines how to perform authentication between an authenticator (for example - a router) and an authentication server that holds a list of usernames and passwords.






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






49. A mapping between each DSCP value and a WRED threshold - often used in Cisco LAN switches when performing WRED.






50. Receiver's advertised window.
