Test your basic knowledge |

CCIE Vocab

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 second byte of the IP header - formerly known as the ToS byte and redefined by DiffServ.






2. Diffusing Update Algorithm.






3. Custom queuing






4. The MD5-encoded password defined by the enable secret command.






5. 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






6. The router that will receive the group traffic when a multicast router forwards group traffic to another router.






7. Link-State Update.






8. A type of routing protocol convergence event in which the metric for a route increases slightly over time because of the advertisement of an invalid route.






9. A method of collecting traffic received on a switch port or a VLAN and sending it to specific destination ports on a switch other than the one on which it was received.






10. 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






11. 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






12. The range 239.0.0.0 through 239.255.255.255 that IANA has assigned for use in private multicast domains.






13. 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.






14. A Cisco-proprietary LMI protocol - implemented in Cisco WAN switches and routers - through which the switch can inform the router about parameters for each VC - including CIR - Bc - and Be.






15. An interface on a Cisco IOS-based switch that is treated as if it were an interface on a switch.






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






17. Virtual LAN.






18. A Cisco IOS queuing tool that uses MQC configuration commands and reserves a minimum bandwidth for each queue.






19. Backward Explicit Congestion Notification.






20. Smoothed Round-Trip Time.






21. With EIGRP - a purposefully slowly changing measurement of round-trip time between neighbors - from which the EIGRP RTO is calculated.






22. Class of Service.






23. Multicast addresses that are not assigned by IANA.






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






25. A Cisco IOS interface software queue queuing strategy implemented automatically when using either form of Frame Relay fragmentation. The system then interleaves packets from the high-priority queue between fragments of the medium-priority queue.






26. WRED compares this setting to the average queue depth to decide whether packets should be discarded. All packets are discarded if the average queue depth rises above this maximum threshold.






27. From one multicast router's perspective - the upstream router is another router that has just forwarded a multicast packet to that router.






28. Designated router.






29. The first 4 bits of the first octet must be 1110. The last 28 bits are unstructured.






30. The process of successive neighboring routers exchanging LSAs such that all routers have an identical LSDB for each area to which they are attached.






31. Service set identifier.






32. With private VLANs - a port that can send and receive frames with all other ports in the private VLAN.






33. Orthogonal frequency division multiplexing.






34. Bipolar 8 Zero Substitution. A serial-line encoding standard that substitutes Bipolar Violations in a string of eight binary 0s to provide enough signal transitions to maintain synchronization.






35. Jargon used by STP mostly when discussing the root election process; refers to a Hello with a lower bridge ID. Sometimes refers to a Hello with the same bridge ID as another - but with better values for the tiebreakers in the election process.






36. 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.






37. A PPP feature used to load balance multiple parallel links at Layer 2 by fragmenting frames - sending one frame over each of the links in the bundle - and reassembling them at the receiving end of the link.






38. DCE devices are one of two devices on either end of a communications circuit - specifically the device with more control over the communications. Frame Relay switches are DCE devices. DCEs are also known as data circuit-terminating equipment (DTE).






39. A reserved value for the BGP COMMUNITY path attribute that implies that the route should not be advertised to any other peer.






40. Ethernet MAC address that represents all devices on the LAN.






41. On a single computer - one layer provides a service to a higher layer. The software or hardware that implements the higher layer requests that the next lower layer perform the needed function.






42. Ethernet feature in which a NIC or Ethernet port can both transmit and receive at the same instant in time. It can be used only when there is no possibility of collisions. Loopback circuitry on NIC cards is disabled to use full duplex.






43. An NTP mode in which an NTP host does not adjust its clock - but in which it sends NTP messages to clients so that the clients can update their clocks based on the server's clock.






44. An OSPF external route for which internal OSPF cost is added to the cost of the route as it was redistributed into OSPF.






45. A route that is used for forwarding packets when the packet does not match any more specific routes in the IP routing table.






46. 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.






47. 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






48. Distance Vector Multicast Routing Protocol.






49. A routing protocol feature by which the routing update includes the entire set of routes - even if some or all of the routes are unchanged.






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