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 MPLS VPNs - an entity in a single router that provides a means to separate routes in different VPNs. The VRF includes per-VRF instances of routing protocols - a routing table - and an associated CEF FIB.






2. 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.






3. Dynamic Host Configuration Protocol.






4. The process of taking routes known through one routing protocol and advertising those routes with another routing protocol.






5. A term generally describing characteristics about BGP paths that are advertised in BGP Updates.






6. An EIGRP message that is used by neighbors to reply to a query. Reply messages require an Ack.






7. A BGP ASN whose value is between 64 -512 and 65 -535. These values are not assigned for use on the Internet - and can be used for private purposes - typically either within confederations or by ISPs to hide the ASN used by some customers.






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






9. The portion of PPP focused on features that are unrelated to any specific Layer 3 protocol.






10. Per-VLAN Spanning Tree Plus.






11. A term referring to EIGRP's internal processing logic.






12. When multiple routers are connected to a subnet - only one should be sending IGMP queries. It is called a querier. IGMPv1 does not have any rules for electing a querier. In IGMPv2 and IGMPv3 - a router with the lowest interface IP address on the subn






13. 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.






14. Each 802.11 station passively monitors each RF channel for a specific amount of time and listens for beacons. Stations use the signal strengths of found beacons to determine the access point or ad hoc network with which to attempt association.






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






16. Orthogonal frequency division multiplexing.






17. The first 6 bits of the DS field - used for QoS marking.






18. 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.






19. In the PIM-SM design - the process by which a PIM-SM router can build the SPT between itself and the source of a multicast group and take advantage of the most efficient path available from the source to the router as long as it has one directly conn






20. Provider edge.






21. The IP address to which Label Distribution Protocol (LDP) sends LDP Hellos. Also used in IP multicast to send packets to all multicast routers.






22. The command used to initialize a SPAN or RSPAN session on a Catalyst switch.






23. A protection against problems caused by unidirectional links between two switches. Uses messaging between switches to detect the loop - err-disabling the port when the link is unidirectional.






24. With EIGRP - a timer started when a reliable (to be acknowledged) message is transmitted. For any neighbor(s) failing to respond in its RTO - the RTP protocol causes retransmission. RTO is calculated based on SRTT.






25. A WFQ term referring to its drop logic - which is similar to tail-drop behavior.






26. Instead of advertising all routes out a particular interface - the routing protocol omits the routes whose outgoing interface field matches the interface out which the update would be sent.






27. 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.






28. Discard Eligible.






29. Static length subnet masking.






30. Common Spanning Tree.






31. Controls the distribution of multicast traffic by checking the TTL values configured on the interfaces. It forwards the multicast packet only on those interfaces whose configured TTL value is less than or equal to the TTL value of the multicast packe






32. A Cisco IOS queuing tool that uses MQC configuration commands - reserves a minimum bandwidth for some queues - provides high-priority scheduling for some queues - and polices those queues to prevent starvation of lower-priority queues during interfac






33. A switch feature that examines incoming frames - comparing the source IP and MAC addresses to the DHCP snooping binding database - filtering frames whose addresses are not listed in the database for the incoming interface.






34. A mechanism for conserving battery power in wireless stations. The access point buffers data frames destined to sleeping stations - which wake periodically to learn from information in the beacon frame whether or not data frames are waiting for trans






35. Also known as triggered updates.






36. Classless interdomain routing.






37. The process of forwarding packets through a router. Also called IP forwarding.






38. Removing unwanted VLANs from a Layer 2 path.






39. An exterior routing protocol that predates BGP. It is no longer used today.






40. One-time password.






41. A configuration tool in Cisco IOS that allows basic programming logic to be applied to a set of items. Often used for decisions about what routes to redistribute - and for setting particular characteristics of those routes






42. 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.






43. Out of Frame.






44. A method of obtaining an IPv6 address that uses DHCPv6. See also stateless autoconfiguration.






45. Committed information rate.






46. Sent by a PIM router - by default every 30 seconds - on every interface on which PIM is configured to discover neighbors - establish adjacency - and maintain adjacency.






47. Challenge Handshake Authentication Protocol.






48. In the context of SNMP - the Trap command is sent by an SNMP agent - to a manager - when the agent wants to send unsolicited information to the manager. Trap is not followed by a Response message from the receiving SNMP manager.






49. Digital Signal Level 3.






50. Network Address Translation.
