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. 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.






2. The number of beacons that governs how often multicast frames are sent over a wireless LAN.






3. A small FIFO queue associated with each router's physical interface - for the purpose of making packets available to the interface hardware - removing the need for a CPU interrupt to start sending the next packet out the interface.






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






5. An IPv6 address type that is used by a number of hosts in a network that are providing the same service. Hosts accessing the service are routed to the nearest host in an anycast environment based on routing protocol metrics.






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






7. Provider router.






8. Finish time.






9. 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.






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






11. A NAT term describing an IP address representing a host that resides inside the enterprise network - with the address being used in packets inside the enterprise network.






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






13. In switch port security - the process whereby the switch dynamically learns the MAC address(es) of the device(s) connected to a switch port - and then adds those addresses to the running configuration as allowed MAC addresses for port security.






14. Digital Signal Level 1.






15. A BGP path attribute that implies how the route was originally injected into some router's BGP table.






16. In the context of SNMP - the GetNext command is sent by an SNMP manager - to an agent - requesting the value of a single MIB variable. The GetNext request identifies a variable for which the manager wants the variable name and value of the next MIB l






17. An STP timer that dictates the interval at which the Root switch generates and sends Hello BPDUs.






18. With shaping - the number of bits allowed to be sent every Tc. Also defines the size of the token bucket when Be = 0.






19. With private VLANs - a secondary VLAN in which the ports can send and receive frames only with promiscuous ports in the primary VLAN.






20. Generic routing encapsulation.






21. Dynamic Trunking Protocol.






22. In OSPF - a router that is prepared to take over the designated router.






23. Reported distance or Route Distinguisher.






24. Advanced Encryption Standard A superior encryption mechanism that is part of the 802.11i standard and has much stronger security than TKIP.






25. Structure of Management Information.






26. Cisco Express Forwarding.






27. A serial-line encoding standard like B8ZS - but with each set of four consecutive 0s being changed to include a Bipolar Violation to maintain synchronization.






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






29. Retransmission Timeout.






30. With PIM on a multiaccess network - the PIM router with the highest IP address on the subnet. It is also the IGMPv1 Querier. The DR is responsible for the following tasks: - Sending PIM register and PIM join and prune messages toward the RP to infor






31. An optional contention-free 802.11 access protocol that requires the access point to poll wireless stations before they are able to send frames. Not commonly implemented.






32. EIGRP jargon meaning that EIGRP has placed a route into active status.






33. Cisco-proprietary VLAN trunking protocol.






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






35. Extensible Authentication Protocol.






36. Data communications equipment.






37. In the PIM-SM design - the process by which a source DR - after it starts to receive the group traffic - encapsulates the multicast packets in the unicast packets and sends them to the RP.






38. Cisco-proprietary STP feature in which an access layer switch is configured to be unlikely to become Root or to become a transit switch. Also - convergence upon the loss of the switch's Root Port takes place in a few seconds.






39. Variable-length subnet masking.






40. Port Aggregation Protocol.






41. Reliable Transport Protocol.






42. A standard (RFC 3768) feature by which multiple routers can provide interface IP address redundancy so that hosts using the shared - virtual IP address as their default gateway can still reach the rest of a network even if one or more routers fail.






43. Method by which a dense-mode routing protocol distributes multicast traffic from a source to all the segments of a network. Also called shortest-path tree (SPT) - because it uses the shortest routing path from the source to the segments of the networ






44. When a PIM-SM router switches from RPT to SPT - it sends a PIM-SM Prune message for the source and the group with the RP bit set to its upstream router on the shared tree. RFC 2362 uses the notation PIM-SM (S - G) RP-bit Prune for this message.






45. Copper cable with RJ-45 connectors in which a twisted pair at pins 1 -2 on the first end of the cable is connected to pins 3 -6 on the other end - with a second pair connected to pins 3 -6 on the first end and pins 1 -2 on the other end.






46. Feasible distance.






47. In IPv6 - the Neighbor Discovery message used by an IPv6 node to request information about a neighbor or neighbors.






48. 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.






49. An FRTS configuration construct - configured with the map-class frame-relay global configuration command.






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