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






2. A Frame Relay traffic shaping feature during which the shaping rate is reduced when the shaper notices congestion through the receipt of BECN or ForeSight messages.






3. A bit in the LAPF Frame Relay header that - when set to 1 - implies that the frame has experienced congestion.






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






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






6. With private VLANs - a secondary VLAN in which the ports can send and receive frames with each other - but not with ports in other secondary VLANS.






7. 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.






8. Defined in RFC 3748 - the protocol used by IEEE 802.1X for exchanging authentication information.






9. Enhances RP redundancy by providing a method for RPs to exchange multicast source information - even between multicast domains.






10. Edge LSR.






11. An IOS feature in which multiple routing tables and routing forwarding instances exist in a single router - with interfaces being assigned to one of the several VRFs. This feature allows separating of routing domains inside a single router platform.






12. Another name for 802.1Q-in-Q. See 802.1Q-in-Q.






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






14. Reported distance or Route Distinguisher.






15. A 3-bit field in an MPLS header used for marking frames.






16. Label Distribution Protocol.






17. Virtual Router Redundancy Protocol.






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






19. An integer setting for EIGRP and IGRP. Any FS route whose metric is less than this variance multiplier times the successor's metric is added to the routing table - within the restrictions of the maximum-paths command.






20. Defines a particular wireless LAN. The SSID configured in the radio card must match the SSID in the access point before the station can connect with the access point.






21. The Lempel Ziv STAC compression algorithm is used in Frame Relay networks to define dynamic dictionary entries that list a binary string from the compressed data and an associated smaller string that represents it during transmission






22. A state for a route in an EIGRP topology table that indicates that the router is actively sending Query messages for this route - attempting to validate and learn the current best route to that subnet.






23. 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






24. A style of attack in which an ICMP Echo is sent with a directed broadcast (subnet broadcast) destination IP address - and a source address of the host that is being attacked. The attack can result in the Echo reaching a large number of hosts - all of






25. A BGP feature by which a router learns iBGP routes - and then forwards them to other iBGP peers - reducing the required number of iBGP peers while also avoiding routing loops.






26. Spanning Tree Protocol.






27. Virtual LAN.






28. An individual line in an ACL.






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






30. A type of logic for how a router uses a default route. A convention for discussing and thinking about IP addresses by which class A - B - and C default network prefixes (of 8 - 16 - and 24 bits - respectively) are considered.






31. A predefined VC. A PVC can be equated to a leased line in concept.






32. Network Address Translation-Protocol Translation.






33. 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.






34. Message sent by a PIM-DM router to a downstream router when it receives a Graft message from the downstream router; sent using the unicast address of the downstream router.






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






36. Management Information Base.






37. A list of interspersed alphanumeric literals and metacharacters that are used to apply complex matching logic to alphanumeric strings. Often used for matching AS_PATHs in Cisco routers.






38. Frame Relay Forum.






39. Data communications equipment.






40. Border Gateway Protocol.






41. 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.






42. An Internet standard authentication protocol that uses clear-text passwords and a two-way handshake to perform authentication over a PPP link.






43. 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.






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






45. Local Management Interface.






46. A type of OSPF NSSA area for which neither external (type 5) LSAs are introduced - nor type 3 summary LSAs; instead - the ABRs originate and inject default routes into the area. External routes can be injected into a totally NSSA area.






47. An EIGRP message that is used to acknowledge reliable EIGRP messages - namely Update - Query - and Reply messages. Acks do not require an Ack.






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






49. The PPP function for fragmenting packets - plus interleaving delay-sensitive later-arriving packets between the fragments of the first packet.






50. Dynamic ARP Inspection.
