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. Out of Frame.






2. Inverse ARP.






3. Protocol Independent Multicast dense-mode routing protocol.






4. Ethernet process by which devices attached to the same cable negotiate their speed and the duplex settings over the cable.






5. A Cisco IOS feature that performs deep packet inspection to classify packets based on application layer information.






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






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






8. When subnetting a class A - B - or C address - the subnet for which all subnet bits are binary 1.






9. A set of DiffServ PHBs that defines 12 DSCP values - with four queuing classes and three drop probabilities within each queuing class.






10. EIGRP (and IGRP) allows for the use of bandwidth - load - delay - MTU - and link reliability; the K values refer to an integer constant that includes these five possible metric components. Only bandwidth and delay are used by default - to minimize re






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






12. An optimized Layer 3 forwarding path through a router or switch. CEF optimizes routing table lookup by creating a special - easily searched tree structure based on the contents of the IP routing table. The forwarding information is called the Forward






13. A Cisco 12000 series router feature that combines the key features of LLQ and CQ to provide similar congestion-management features.






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






15. 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.






16. With PIM on a multiaccess network - the PIM router with the highest IP address on the subnet. It is also the IGMPv1 Querier. The DR is responsible for the following tasks: - Sending PIM register and PIM join and prune messages toward the RP to infor






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






18. Designed to solve the problems of multicast duplication and multicast routing loops. For every multicast packet received - a multicast router examines its source IP address - consults its unicast routing table - determines which interface it would us






19. With EIGRP - the metric value for the lowest-metric route to a particular subnet.






20. Any other router - sharing a common data link - with which a router exchanges Hellos - and for which the parameters in the Hello pass the parameter-check process.






21. An EIGRP router's reaction to an input event - leading to the use of a feasible successor or going active on a route.






22. Multicast addresses that are not assigned by IANA.






23. With private VLANs - a secondary VLAN in which the ports can send and receive frames only with promiscuous ports in the primary VLAN.






24. IP multicast address range from 224.0.0.0 through 239.255.255.255.






25. An MPLS VPN term referring to the more efficient choice of popping the outer label at the second-to-last (penultimate) LSR - which then prevents the egress PE from having to perform two LFIB lookups to forward the packet.






26. An enhanced version of T1 framing - as compared with the earlier Superframe (D4) standard.






27. An IPv6 address type that is used by a number of hosts in a network that are providing the same service. Hosts accessing the service are routed to the nearest host in an anycast environment based on routing protocol metrics.






28. 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.






29. Clear To Send.






30. A BGP feature that overcomes the requirement of a full mesh of iBGP peers inside a single AS by separating the AS into multiple sub-autonomous systems.






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






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






33. An MPLS application that allows the MPLS network to connect to multiple different IP networks - with overlapping IP addresses - and provide IP connectivity to those multiple networks.






34. Flush timer.






35. Backward Explicit Congestion Notification.






36. A Cisco IOS queuing tool most notable for its scheduler - which always services the high-priority queue over all other queues.






37. A characteristic of OSPF interfaces that determines whether a DR election is attempted - whether or not neighbors must be statically configured - and the default Hello and Dead timer settings.






38. A characterization of a BGP path attribute in which all BGP implementations must support and understand the attribute (well known) - and all BGP Updates must include the attribute (mandatory).






39. With Spanning Tree Protocol - the single port on each LAN segment from which the best Hello BPDU is forwarded.






40. Measured Round-Trip Time.






41. An optional nontransitive BGP path attribute that lists the route reflector cluster IDs through which a route has been advertised - as part of a loop-prevention process similar to the AS_PATH attribute.






42. Cisco-proprietary VLAN trunking protocol.






43. The process by which neighboring OSPF routers examine their Hello messages and elect the DR. The decision is based on priority (highest) - or RID (highest) if priority is a tie.






44. A BGP process by which a router reapplies routing policy configuration (route maps - filters - and the like) based on stored copies of sent and received BGP Updates.






45. A router that should either permanently or temporarily not be used as a transit router. Can wait a certain time after OSPF process start - or after BGP notifies OSPF that BGP has converged - before ceasing to be a stub router.






46. Loss of Signal. A T1 alarm state that occurs when the receiver has not received any pulses of either polarity for a defined time period.






47. Route Target.






48. With RIP - a per-route timer (default 180 seconds) that begins when a route's metric changes to a larger value.






49. A numeric value between 0 and 32 (inclusive) that defines the number of beginning bits in an IP address for which all IP addresses in the same group have the same value. Alternative: The number of binary 1s beginning a subnet mask - written as a deci






50. A group of devices on one or more LANs that are configured (using management software) so that they can communicate as if they were attached to the same wire - when - in fact - they are located on a number of different LAN segments. Because VLANs are
