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. A set of four hex digits listed in an IPv6 address. Each quartet is separated by a colon.






2. An Internet standard authentication protocol that uses secure hashes and a three-way handshake to perform authentication over a PPP link.






3. After a host receives an IGMP Query - the amount of time (default - 10 seconds) the host has to send the IGMP Report.






4. An ITU standard Frame Relay header - including the DLCI - DE - FECN - and BECN bits in the LAPF header - and a frame check in the LAPF trailer.






5. A method for optimizing the flow of multicast IP packets passing through a LAN switch. The switch using IGMP snooping examines IGMP messages to determine which ports need to receive traffic for each multicast group.






6. A BGP router that forwards iBGP-learned routes to other iBGP routers.






7. A 3-bit field in an 802.1Q header used for marking frames.






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






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






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






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






12. Sent by a PIM-DM or PIM-SM router when it receives a multicast packet for a group on a LAN interface that is in the outgoing interface list for the group; includes the administrative distance of the unicast routing protocol used to learn the network






13. One-time password.






14. A mapping between each DSCP value and a WRED threshold - often used in Cisco LAN switches when performing WRED.






15. An E-LSR in an MPLS VPN network whose role in a particular discussion is to receive labeled packets from other LSRs and then forward the packets as unlabeled packets to CE routers.






16. A packet-scheduling algorithm used in Cisco switches that provides similar behavior to CBWFQ in shared mode and polices in shaped mode.






17. The protocol used in IPv6 for many functions - including address autoconfiguration - duplicate address detection - router - neighbor - and prefix discovery - neighbor address resolution - and parameter discovery.






18. A protocol - defined in RFC 2865 - that defines how to perform authentication between an authenticator (for example - a router) and an authentication server that holds a list of usernames and passwords.






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






20. Jargon referring to any queue that receives priority service - often used for queues in an LLQ configuration that have the priority command configured.






21. Variable name for the time interval used by shapers and by CAR.






22. 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.






23. A term used with Cisco LAN switches - referring to a queue treated with strict-priority scheduling.






24. Modular QoS CLI.






25. A BGP router in an AS that uses route reflectors - but that is not aided by any RR server.






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






27. Internet Group Management Protocol.






28. Cisco Group Management Protocol.






29. EAP over LAN.






30. 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.






31. 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.






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






33. Temporal Key Integrity Protocol.






34. On a serial cable - the pin lead set by the DCE to imply a working link.






35. A type of spread spectrum that spreads RF signals over the frequency spectrum by transmitting the signal at different frequencies according to a hopping pattern. One of the original 802.11 physical layers used FHSS to offer data rates of 1 and 2 Mbps






36. A 3-bit field in the first 3 bits of the ToS byte in the IP header - used for QoS marking.






37. The second most significant bit in the most significant byte of an Ethernet MAC address - a value of binary 0 implies that the address is a Universally Administered Address (UAA) (also known as Burned-In Address [BIA]) - and a value of binary 1 impli






38. A characterization of a BGP path attribute in which all BGP implementations must support and understand the attribute (well known) - but BGP Updates can either include the attribute or not depending on whether a related feature has been configured (d






39. A standard (RFC 951) protocol by which a LAN-attached host can dynamically broadcast a request for a server to assign it an IP address - along with other configuration settings - including a subnet mask and default gateway IP address.






40. With EIGRP - the timer used to determine when a neighboring router has failed - based on a router not receiving any EIGRP messages - including Hellos - in this timer period.






41. The portion of PPP focused on negotiating IP features






42. 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.






43. A Cisco IOS queuing tool most notable for its automatic classification of packets into separate per-flow queues.






44. The most significant bit in the most significant byte of an Ethernet MAC address - its value implies that the address is a unicast MAC address (binary 0) or not (binary 1).






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






46. 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






47. A category used by a policer to classify packets relative to the traffic contract. The bit rate implied by all conforming packets is within the traffic contract.






48. 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.






49. Custom queuing






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