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. A Cisco-proprietary Layer 2 protocol that enables a router to communicate to a switch which multicast group traffic the router does and does not want to receive from the switch.






2. With DiffServ - a DSCP marking and a related set of QoS actions applied to packets that have that marking.






3. 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.






4. Dynamic Multipoint VPN.






5. Link Access Procedure for Frame-Mode Bearer Services.






6. Committed Burst.






7. Label switched path.






8. A type of OSPF packet - used to communicate LSAs to another router.






9. A small FIFO queue associated with each router's physical interface - for the purpose of making packets available to the interface hardware - removing the need for a CPU interrupt to start sending the next packet out the interface.






10. A type of OSPF packet used to discover neighbors - check for parameter agreement - and monitor the health of another router.






11. A router feature used when a router sees an ARP request searching for an IP host's MAC - when the router believes the IP host could not be on that LAN because the host is in another subnet. If the router has a route to reach the subnet where the ARP-






12. Sequence number.






13. An STP timer that dictates how long a switch should wait when it ceases to hear Hellos.






14. An ITU standard Frame Relay header - including the DLCI - DE - FECN - and BECN bits in the LAPF header - and a frame check in the LAPF trailer.






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






16. A packet-scheduling algorithm used in Cisco switches that provides similar behavior to CBWFQ in shared mode and polices in shaped mode.






17. 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.






18. The IPv6 protocol used for the discovery of which hosts are listening for which multicast IP addresses for IPv6.






19. A switch feature that limits the number of allowed MAC addresses on a port - with optional limits based on the actual values of the MAC addresses.






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






21. In IPv6 DNS - the IPv6 equivalent of an IPv4 DNS A record.






22. A term used with WFQ for the number assigned to a packet as it is enqueued into a WFQ. WFQ schedules the currently lowest SN packet next.






23. Per-VLAN Spanning Tree Plus.






24. 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.






25. A Cisco-proprietary LMI protocol - implemented in Cisco WAN switches and routers - through which the switch can inform the router about parameters for each VC - including CIR - Bc - and Be.






26. A router that should not be used to forward packets between other routers. Other routers will not send Query messages to a stub router.






27. A state for a route in an EIGRP topology table that indicates that the router believes that the route is stable - and it is not currently looking for any new routes to that subnet.






28. With shaping - the number of bits allowed to be sent every Tc. Also defines the size of the token bucket when Be = 0.






29. An early T1 framing standard.






30. A conceptual model used by CB Policing when using an excess burst.






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






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






33. A Cisco-proprietary feature. After a Cisco multicast router receives IGMP Join or Leave messages from hosts - it communicates to the connected Cisco switches - telling them which hosts (based on their unicast MAC addresses) have joined or left each m






34. 64 bits at the end of an IPv6 global address - used to uniquely identify each host in a subnet.






35. In MQC and CB Policing - a configuration style by which - for one category of packets (conform - exceed - or violate) - more than one marking action is defined for a single category. For example - marking DSCP and DE.






36. A set of parameters for CBAC to perform in its traffic inspection process.






37. A dotted-decimal number that represents a subnet. It is the lowest numeric value in the range of IP addresses implied by a subnet number and prefix/mask.






38. A message that each host sends - either in response to a router Query message or on its own - to all multicast groups for which it would like to receive multicast traffic.






39. From one multicast router's perspective - the upstream router is another router that has just forwarded a multicast packet to that router.






40. A message sent by each host - either in response to a router Query or on its own - to all multicast groups for which it would like to receive multicast traffic.






41. In 802.1X - the computer that stores usernames/passwords and verifies that the correct values were submitted before authenticating the user.






42. An Internet standard (RFC 1305) that defines the messages and modes used for IP hosts to synchronize their time-of-day clocks.






43. With OSPF - the OSPF router that wins an election amongst all current neighbors. The DR is responsible for flooding on the subnet - and for creating and flooding the type 2 LSA for the subnet.






44. The structure inside telcos' original digital circuit build-out in the mid-1900s - based upon using TDM to combine and disperse smaller DS levels into larger levels - and vice versa.






45. Virtual Routing and Forwarding table.






46. A serial-line encoding standard that substitutes Bipolar Violations in a string of eight binary 0s to provide enough signal transitions to maintain synchronization.






47. Peak information rate.






48. 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.






49. Layer x PDU.






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