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. 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






2. Secure Shell protocol used for character-oriented command-line access and configuration. A highly secure alternative to Telnet.






3. The process of forwarding packets through a router. Also call IP routing.






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






5. Virtual Routing and Forwarding table.






6. Reduces the bandwidth necessary for radio management information - such as access point status messages - that is sent across the network by eliminating redundant management information.






7. With some routing protocols - the time period between successive Hello messages.






8. An MPLS term referring to the first of several labels when an MPLS-forwarded packet has multiple labels (a label stack).






9. Penultimate hop popping.






10. Ethernet MAC address that represents a single NIC or interface.






11. 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.






12. Used by WRED to calculate the rate at which the average queue depth changes as compared with the current queue depth. The larger the number - the slower the change in the average queue depth.






13. The operating mode of shaped round-robin that provides a low-latency queue with policing.






14. Management Information Base.






15. The Cisco IOS feature by which special short key sequences can be used to move the cursor inside the current command line to more easily change a command.






16. Virtual Router Redundancy Protocol.






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






18. The content engine in a WCCP cluster - which determines how traffic will be distributed within the cluster.






19. A standards-based way of helping routers find Rendezvous Points (RP). RPs notify BSRs of the groups they handle. BSRs in turn flood the group-to-RP mappings throughout the network. Each router individually determines which RP to use for a particular






20. 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






21. 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.






22. Point-to-Point Protocol.






23. An IPv6/IPv4 tunneling method that is designed for transporting IPv6 packets within a site where a native IPv6 infrastructures is not available.






24. An EIGRP message that informs neighbors about routing information. Update messages require an Ack.






25. An 802.1d STP transitory port state in which the port does not send or receive frames - but does learn the source MAC addresses from incoming frames.






26. Label Distribution Protocol.






27. A prestandard (at the time of publication) wireless LAN physical layer that offers data rates in the hundreds of megabits per second.






28. A multicast routing protocol whose default action is to flood multicast packets throughout a network.






29. A standard (RFC 903) protocol by which a LAN-attached host can dynamically broadcast a request for a server to assign it an IP address. See also ARP.






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






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






32. 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.






33. Class-Based Weighted Fair Queuing.






34. Alternate Mark Inversion. A serial-line encoding standard that sends alternating positive and negative 3-volt signals for binary 1 - and no signal (0 V) for binary 0.






35. Structure of Management Information.






36. A mapping between each DSCP value and a corresponding CoS value - often used in Cisco LAN switches when performing classification for egress queuing.






37. 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.






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






39. A strategy for subnetting a classful network for which all masks/prefixes are the same value for all subnets of that one classful network.






40. 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.






41. A type of spread spectrum that spreads RF signals over the frequency spectrum by representing each data bit by a longer code. 802.11b specifies the use of DSSS.






42. An EIGRP message that is used to ask neighboring routers to verify their route to a particular subnet. Query messages require an Ack.






43. Distance Vector Multicast Routing Protocol.






44. Exterior Gateway Protocol.






45. 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).






46. Type of Service byte.






47. The range 232.0.0.0 through 232.255.255.255 that is allocated by IANA for SSM destination addresses and is reserved for use by source-specific applications and protocols.






48. Backup designated router.






49. A term referring to the MQC policy-map command and its related subcommands - which are used to apply QoS actions to classes of packets.






50. A process whereby a switch - when making a forwarding decision - uses not only Layer 2 logic but other OSI layer equivalents as well.
