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






2. 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.






3. A security standard that includes both TKIP and AES and was ratified by the Wi-Fi Alliance.






4. A Cisco IOS queuing tool most notable for its scheduler - which always services the high-priority queue over all other queues.






5. Designated router.






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






7. The term referring to a group of iBGP routers in a confederation - with the group members being assigned a hidden ASN for the purposes of loop avoidance.






8. A vendor consortium that formerly worked to further Frame Relay common vendor standards.






9. A queue created by Cisco IOS as a result of the configuration of a queuing tool.






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






11. An address type in IPv6 networks that is used only on the local link and never beyond that scope.






12. Customer edge.






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






14. With routing protocols - the process by which the router receiving a routing update determines if the routing update came from a trusted router.






15. 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.






16. A T1 alarm state that occurs when a device receives a Yellow Alarm signal. This typically means that the device on the other end of the line is in a Red Alarm state.






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






18. Structure of Management Information.






19. Orthogonal frequency division multiplexing.






20. Receivers subscribe to an (S -G) channel when they request to join a multicast group. That is - they specify the unicast IP address of their multicast source and the group multicast address. SSM is typically used in very large multicast deployments s






21. Differentiated Services Code Point.






22. Loss of Frame.






23. The one VLAN on an 802.1Q trunk for which the endpoints do not add the 4-byte 802.1Q tag when transmitting frames in that VLAN.






24. 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.






25. VTP pruning.






26. The Cisco IOS Router IP Traffic Export feature - intended for intrusion detection - exports IP traffic that has signs of an attack - such as duplicate IP packets simultaneously received on two or more of a router's interfaces.






27. Data communications equipment.






28. Protects against problems caused by unidirectional links between two switches. Watches for loss of received Hello BPDUs - in which case it transitions to a loop-inconsistent state instead of transitioning to a forwarding state.






29. Aka receiver's advertised window.






30. Neighbor Advertisement.






31. An IPv6 migration strategy in which a host or router supports both IPv4 and IPv6 natively.






32. A type of OSPF stub area that - unlike stub areas - can inject external routes into the NSSA area.






33. The range 233.0.0.0 through 233.255.255.255 that IANA has reserved (RFC 2770) on an experimental basis. It can be used by anyone who owns a registered autonomous system number to create 256 global multicast addresses.






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






35. The Frame Relay protocol used between a DCE and DTE to manage the connection. Signaling messages for SVCs - PVC Status messages - and keepalives are all LMI messages.






36. A table used by CEF that holds information about adjacent IP hosts to which packets can be forwarded.






37. Multicast Open Shortest Path First.






38. An MPLS data structure used for forwarding labeled packets. The LFIB lists the incoming label - which is compared to the incoming packet's label - along with forwarding instructions for the packet.






39. Switched virtual circuit.






40. From a Layer 1 perspective - the process of using special strings of electrical signals over a transmission medium to inform the receiver as to which bits are overhead bits - and which fit into individual subchannels.






41. A switch feature that limits the number of allowed MAC addresses on a port - with optional limits based on the actual values of the MAC addresses.






42. A term used with Cisco LAN switches - referring to a DSCP value used when making QoS decisions about a frame. This value may not be the actual DSCP value in the IP header encapsulated inside the frame.






43. In BGP - either external BGP (eBGP) - confederation eBGP - or internal BGP (iBGP). The term refers to a peer connection - and whether the peers are in different ASs (eBGP) - different confederation sub-ASs (confederation eBGP) - or in the same AS (iB






44. A characterization of a BGP path attribute in which BGP implementations are not required to support the attribute (optional) - and for which if a router receives a route with such an attribute - the router should forward the attribute unchanged (tran






45. Defined in RFC 826 - a protocol used on LANs so that an IP host can discover the MAC address of another device that is using a particular IP address.






46. 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.






47. A predefined VC. A PVC can be equated to a leased line in concept.






48. A basic form of traffic shaping that is applied to an interface or subinterface. By default - it shapes all traffic leaving the interface - but can be modified by using an access control list. The access list controls only what traffic is shaped; GTS






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






50. An MPLS VPN term referring to the more efficient choice of popping the outer label at the second-to-last (penultimate) LSR - which then prevents the egress PE from having to perform two LFIB lookups to forward the packet.
