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. Web Cache Communication Protocol.






2. The process of combining multiple synchronized input signals over a single medium by giving each signal its own time slot - and then breaking out those signals.






3. The portions of PPP focused on features that are related to specific Layer 3 protocols.






4. The destination VLAN for an RSPAN session.






5. Classless interdomain routing.






6. A Cisco-proprietary protocol - used by LAN switches to communicate VLAN configuration.






7. When subnetting a class A - B - or C address - the subnet for which all subnet bits are binary 1.






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






9. Copper cable with RJ-45 connectors in which the wire at pin 1 on one end is connected to pin 1 on the other end; the wire at pin 2 is connected to pin 2 on the other end; and so on.






10. 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.






11. In MPLS - a term used to define a label that an LSR allocates and then advertises to neighboring routers. The label is considered "local" on the router that allocates and advertises the label.






12. The RFC 1997 name for the reserved COMMUNITY path attribute known to Cisco IOS as LOCAL_AS. (See LOCAL_AS.)






13. A conceptual model used by CB Policing when using an excess burst.






14. A technology that enables frequency reuse. Two variants exist: frequency hopping (FHSS) and direct sequence (DSSS). Both techniques spread the signal power over a relatively wide portion of the frequency spectrum over time - to reduce interference be






15. Provider edge.






16. Per-VLAN Spanning Tree Plus.






17. In IPv6 - the Neighbor Discovery message used by an IPv6 node to send information about itself to its neighbors.






18. Layer x PDU.






19. A state for a route in an EIGRP topology table that indicates that the router believes that the route is stable - and it is not currently looking for any new routes to that subnet.






20. A 3-bit field in an ISL header used for marking frames. Also - used generically to refer to either the ISL CoS field or the 802.1Q User Priority field.






21. The process of taking the payload inside a Layer 2 frame - including the headers of Layer 3 and above - compressing the data - and then uncompressing the data on the receiving router.






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






23. A Cisco-proprietary protocol used to dynamically negotiate whether the devices on an Ethernet segment want to form a trunk and - if so - which type (ISL or 802.1Q).






24. The most recent standardized set of generic SNMP MIB variables - defined in RFC 1213 and updated in RFCs 2011 through 2013.






25. A commonly used name for Multi-VRF CE.






26. 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.






27. The original standardized set of generic SNMP MIB variables - defined in RFC 1158.






28. A name used for DS3 lines inside the North American TDM hierarchy.






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






30. The process of taking the IP - UDP - and RTP headers of a voice or video packet - compressing them - and then uncompressing them on the receiving router.






31. 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.






32. AS number. A number between 1 and 64 -511 (public) and 64 -512 and 65 -535 (private) assigned to an AS for the purpose of identifying a specific BGP domain.






33. A 48-bit address that is calculated from a Layer 3 multicast address by using 0x0100.5E as the multicast vendor code (OUI) for the first 24 bits - always binary 0 for the 25th bit - and copying the last 23 bits of the Layer 3 multicast address.






34. A designated router that is directly connected with a source of the multicast group.






35. In MPLS - a term used to define a label that an LSR learned from a neighboring LSR.






36. 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.






37. An optional nontransitive BGP path attribute that lists the route reflector cluster IDs through which a route has been advertised - as part of a loop-prevention process similar to the AS_PATH attribute.






38. With EIGRP - the route to each destination for which the metric is the lowest of all known routes to that network.






39. A queuing scheduler's logic by which - if a particular queue has packets in it - those packets always get serviced next.






40. The algorithm used by OSPF and IS-IS to compute routes based on the LSDB.






41. Aka minimum CIR.






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






43. The speed at which the access link is clocked. This choice affects the price of the connection and many aspects of traffic shaping and policing - compression - quality of service - and other configuration options.






44. A router feature used when a router sees an ARP request searching for an IP host's MAC - when the router believes the IP host could not be on that LAN because the host is in another subnet. If the router has a route to reach the subnet where the ARP-






45. Out of Frame.






46. Defined in RFC 2091 - the extensions define how RIP may send a full update once - and then send updates only when routes change - when an update is requested - or when a RIP interface changes state from down to up.






47. Single-bit fields in the TCP header. For example - the TCP SYN and ACK code bits are used during connection establishment.






48. On a multiaccess network - when a PIM-DM or PIM-SM router receives a Prune message - it starts a 3-second timer. If it receives a Join message on the multiaccess network from another router before the timer expires - it considers the message as an ov






49. In shaping and policing - commonly used to refer to the shaping or policing rate. For WAN services - a common reference to the bit rate defined in the WAN service business contract for each VC.






50. Password Authentication Protocol.
