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. Temporal Key Integrity Protocol.






2. Data-link connection identifier.






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






4. In the PIM-SM design - the process by which a source DR - after it starts to receive the group traffic - encapsulates the multicast packets in the unicast packets and sends them to the RP.






5. With EIGRP - a route that is not a successor route - but that meets the feasibility condition; can be used when the successor route fails - without causing loops.






6. Backup designated router.






7. A router that is allowed to receive a packet from an OSPF router and then forward the packet to another OSPF router.






8. Per-Hop Behavior.






9. In BGP - a configuration construct in which multiple neighbors' parameters can be configured as a group - thereby reducing the length of the configuration. Additionally - BGP performs routing policy logic against only one set of Updates for the entir






10. A Cisco-proprietary messaging protocol used to negotiate the dynamic creation of PortChannels (EtherChannels) and to choose which ports can be placed into an EtherChannel.






11. EIGRP jargon meaning that EIGRP has placed a route into active status.






12. Service set identifier.






13. The destination VLAN for an RSPAN session.






14. The data structure used by OSPF to hold LSAs.






15. 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






16. 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






17. Class-Based Weighted Fair Queuing.






18. An 802.1d STP transitory port state in which the port does not send or receive frames - and does not learn MAC addresses - but does wait for STP convergence and for CAM flushing by the switches in the network.






19. Priority queue and priority queuing.






20. A queue created by Cisco IOS as a result of the configuration of a queuing tool.






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






22. The same thing as TCP code bits. See TCP code bits.






23. Regeneration of the Layer 2 encapsulation removed from frames forwarded in a SPAN session.






24. A queuing scheduler concept - much like CQ's scheduler - in which queues are given some service in sequence. This term is often used with queuing in Cisco LAN switches.






25. Edge LSR.






26. A set of all devices for which any frame sent by one of the devices would collide with any frames transmitted at the same time by any of the other devices in the set.






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






28. Version 6 of the IP protocol - which uses 128-bit IP addresses.






29. With routing protocols - the measurement of favorability that determines which entry will be installed in a routing table if more than one router is advertising that exact network and mask.






30. A router that is not an ABR or ASBR in that all of its interfaces connect to only a single OSPF area.






31. A Cisco IOS configuration tool for RIP and EIGRP for which the list matches routes in routing updates - and adds a defined value to the sent or received metric for the routes. The value added to the metric is the offset.






32. A VC that is set up dynamically when needed. An SVC can be equated to a dial-on-demand connection in concept.






33. Classless interdomain routing.






34. Used by RRs to denote the RID of the iBGP neighbor that injected the NLRI into the AS.






35. A multicast routing protocol that operates in dense mode and depends on the OSPF unicast routing protocol to perform its multicast functions.






36. A calculation of the length of the AS_PATH PA - which includes 1 for each number in the AS_SEQ - 1 for an entire AS_SET segment - and possibly other considerations.






37. A logical concept that represents the path over which frames travel between DTEs. VCs are particularly useful when comparing Frame Relay to leased physical circuits.






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






39. Not-so-stubby area.






40. Jargon referring to a policer action through which - instead of discarding an out-of-contract packet - the policer marks a different IPP or DSCP value - allowing the packet to continue on its way - but making the packet more likely to be discarded la






41. 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.






42. The signal strength of the RF signal at the output of the radio card or access point transmitter - before being fed into the antenna. Measured in milliwatts - watts - or dBm.






43. Sent by a PIM router to its upstream router to either request that the upstream router forward the group traffic or stop forwarding the group traffic that is currently being forwarded. If a PIM router wants to start receiving the group traffic - it l






44. EAP over LAN.






45. An MPLS VPN term referring to any LSR that connects to customers to support the forwarding of unlabeled packets - as well as connecting to the MPLS network to support labeled packets - thereby making the LSR be on the edge between the provider and th






46. A term referring to how a router views a BGP peer relationship - in which the peer is in another AS.






47. Label Forwarding Information Base.






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






49. The condition in which a route has been in an EIGRP active state for longer than the router's Active timer.






50. A single label and link that is part of a complete LDP. See also label switched path.
