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. Defined in RFC 826 - a protocol used on LANs so that an IP host can discover the MAC address of another device that is using a particular IP address.






2. A type of AS_PATH segment consisting of an ordered list of ASNs through which the route has been advertised.






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






4. 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.






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






6. Label switched path.






7. An interface on a Cisco IOS-based switch that is treated as if it were an interface on a router.






8. The algorithm used by OSPF and IS-IS to compute routes based on the LSDB.






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






10. Extensible Authentication Protocol.






11. Designated router.






12. The specific frequency subband on which the radio card or access point is operating. The RF channel is set in the access point or ad hoc stations.






13. A set of all devices that receive broadcast frames originating from any device within the set. Devices in the same VLAN are in the same broadcast domain.






14. VLAN Trunking Protocol.






15. Any OSPF neighbor for which the database flooding process has completed.






16. A queuing scheduler's logic by which - if a particular queue has packets in it - those packets always get serviced next.






17. An NTP client that assumes that a server will send NTP broadcasts - removing the requirement for the client to have the NTP server's IP address preconfigured.






18. An OSPF router that connects to the backbone area and to one or more non-backbone area.






19. On a serial cable - the pin lead set by the DTE to tell the DCE that the DTE wants to send data.






20. WRED compares this setting to the average queue depth to decide whether packets should be discarded. No packets are discarded if the average queue depth falls below this minimum threshold.






21. An Internet standard serial data-link protocol - used on synchronous and asynchronous links - that provides data-link framing - link negotiation - Layer 3 interface features - and other functions.






22. A characterization of a network attack in which packets flow to the attacker - and then out to the true recipient. As a result - the user continues to send data - increasing the chance that the attacker learns more and better information.






23. 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.






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






25. 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.






26. Internal BGP.






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






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






29. An FRF standard for Frame Relay-to-ATM Service Interworking in which both DTEs use Frame Relay - with ATM in between.






30. Operates in dense mode and depends on its own unicast routing protocol that is similar to RIP to perform its multicast functions.






31. 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






32. One of the two modes of MDRR - in which the priority queue is serviced between each servicing of the non-priority queues.






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






34. A Frame Relay address used in Frame Relay headers to identify the VC






35. Timer An STP timer that dictates how long a port should stay in the listening state and the learning state.






36. 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.






37. Defines a particular behavior for FTP regarding the establishment of data TCP connections. In active mode - the FTP client uses the FTP PORT command - over the FTP control connection - to tell the FTP server the port on which the client should be lis






38. In MPLS - a term used to define a label that an LSR allocates and then advertises to neighboring routers. The label is considered "local" on the router that allocates and advertises the label.






39. 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.






40. An exterior routing protocol designed to exchange prefix information between different autonomous systems. The information includes a rich set of characteristics called path attributes - which in turn allows for great flexibility regarding routing ch






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






42. Low-latency queuing.






43. 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






44. A tunneling protocol that can be used to encapsulate many different protocol types - including IPv4 - IPv6 - IPsec - and others - to transport them across a network.






45. A Cisco IOS configuration tool - using the ip as-path access-list command - that defines a list of statements that match the AS_PATH BGP path attribute using regular expressions.






46. A BGP router that - unknown to it - is aided by a route reflector server to cause all iBGP routers in an AS to learn all eBGP-learned prefixes.






47. Port Aggregation Protocol.






48. 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.






49. In BGP - a set of routers inside a single administrative authority - grouped together for the purpose of controlling routing policies for the routes advertised by that group to the Internet.






50. Dynamic Trunking Protocol.
