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 EIGRP message that identifies neighbors - exchanges parameters - and is sent periodically as a keepalive function. Hellos do not require an Ack.






2. Multilayer Switching.






3. Low-latency queuing.






4. Temporal Key Integrity Protocol.






5. The IP address used by hosts as the default gateway in a VRRP configuration. This address is shared by two or more VRRP routers - much as HSRP works.






6. For some encoding schemes - consecutive signals must use opposite polarity in an effort to reduce DC current. A BPV occurs when consecutive signals are of the same polarity.






7. Network Based Application Recognition.






8. The 32-bit number used to represent an OSPF router.






9. Similar to an appliance firewall - in that interfaces are placed into security zones. Traffic is allowed between interfaces in the same zone. You can apply policies to filter and control traffic between zones.






10. A router that should not be used to forward packets between other routers. Other routers will not send Query messages to a stub router.






11. Rendezvous point.






12. A term referring to the MQC policy-map command and its related subcommands - which are used to apply QoS actions to classes of packets.






13. With some routing protocols - the time period between successive Hello messages.






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






15. A reserved value for the BGP COMMUNITY path attribute that implies that the route should not be advertised outside the local confederation sub-AS.






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






17. The first 48 bits of an IPv6 global address - used for efficient route aggregation.






18. Any OSPF neighbor for which the database flooding process has completed.






19. 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.






20. 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.






21. Wired Equivalent Privacy.






22. Often used synonymously with neighbor - but with emphasis on the fact that all required parameters match - allowing routing updates to be exchanged between the routers.






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






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






25. Controls the distribution of multicast traffic by checking the TTL values configured on the interfaces. It forwards the multicast packet only on those interfaces whose configured TTL value is less than or equal to the TTL value of the multicast packe






26. Receiver's advertised window.






27. Digital Signal Level 3.






28. Secure Copy Protocol - one of the many ways of transferring files to and from Cisco IOS routers and switches.






29. VTP process that prevents the flow of broadcasts and unknown unicast Ethernet frames in a VLAN from being sent to switches that have no ports in that VLAN.






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






31. Multiple Spanning Trees.






32. Cell Loss Priority.






33. The structure inside telcos' original digital circuit build-out in the mid-1900s - based upon using TDM to combine and disperse smaller DS levels into larger levels - and vice versa.






34. A process used in routers that are encrypting traffic to permit egress QoS actions to be taken on traffic that is being encrypted on that router. QoS pre-classification keeps a copy of each packet to be encrypted in memory long enough to take the app






35. Port Address Translation.






36. One-time password.






37. 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.






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






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






40. Access Control Server. A term referring generically to a server that performs many AAA functions. It also refers to the software product Cisco Secure Access Control Server.






41. Time-division multiplexing.






42. A bit inside the Frame Relay header that - when set - implies that congestion occurred in the direction opposite (or backward) as compared with the direction of the frame.






43. A neighbor state that signifies the other router has reached neighbor status - having passed the parameter check. The FIB entry details the information needed for forwarding: the next-hop router and the outgoing interface - in an optimized mtrie stru






44. A standards-based way of helping routers find Rendezvous Points (RP). RPs notify BSRs of the groups they handle. BSRs in turn flood the group-to-RP mappings throughout the network. Each router individually determines which RP to use for a particular






45. A logical concept that represents the path over which frames travel between DTEs. VCs are particularly useful when comparing Frame Relay to leased physical circuits.






46. An MPLS term referring to any device that can forward packets that have MPLS labels.






47. Aka minimum CIR.






48. A multicast routing protocol that forwards the multicast traffic only when requested by a downstream router.






49. Data communications equipment.






50. Access Control Entry. An individual line in an ACL.
