  • 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 number between 1 and 64 -511 (public) and 64 -512 and 65 -535 (private) assigned to an AS for the purpose of identifying a specific BGP domain.

2. Dynamic ARP Inspection.

3. A message sent by a host when it wants to leave a group - addressed to the All Multicast Routers address

4. Uses Modular QoS CLI to control the amount and type of traffic handled by the router or switch control plane. Class maps identify traffic types - and then a service policy applied to the device control plane sets actions for each type of traffic.

5. For some encoding schemes - consecutive signals must use opposite polarity in an effort to reduce DC current. A BPV occurs when consecutive signals are of the same polarity.

6. Extended Superframe.

7. A set of QoS RFCs that redefines the IP header's ToS byte - and suggests specific settings of the DSCP field and the implied QoS actions based on those settings.

8. With private VLANs - a port that can send and receive frames with all other ports in the private VLAN.

9. On a serial cable - the pin lead set by the DTE to imply that the DTE is ready to signal using pin leads.

10. Secure Shell protocol used for character-oriented command-line access and configuration. A highly secure alternative to Telnet.

11. Feasible distance.

12. An FRF standard for LFI for data (FRF.3) VCs.

13. From a Layer 1 perspective - the process of using special strings of electrical signals over a transmission medium to inform the receiver as to which bits are overhead bits - and which fit into individual subchannels.

14. A technology that enables frequency reuse. Two variants exist: frequency hopping (FHSS) and direct sequence (DSSS). Both techniques spread the signal power over a relatively wide portion of the frequency spectrum over time - to reduce interference be

15. The mandatory contention-based 802.11 access protocol that is also referred to as CSMA/CA.

16. Class-Based Weighted Fair Queuing.

17. A process on a computing device that issues requests for SNMP MIB variables from SNMP agents - receives and processes the MIB data - and accepts unsolicited Trap messages from SNMP agents.

18. DCE devices are one of two devices on either end of a communications circuit - specifically the device with more control over the communications. Frame Relay switches are DCE devices. DCEs are also known as data circuit-terminating equipment (DTE).

19. 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.

20. Permanent virtual circuit.

21. Committed Burst.

22. 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.

23. 16 bits between the interface ID and global routing prefix in an IPv6 global address - used for subnet assignment inside an enterprise.

24. An optional transitive BGP path attribute that - for a summary route - lists the BGP RID and ASN of the router that created the summary.

25. The number of beacons that governs how often multicast frames are sent over a wireless LAN.

26. Network Time Protocol.

27. Hot Standby Router Protocol.

28. Committed information rate.

29. A BGP path attribute that lists the next-hop IP address used to reach an NLRI.

30. Variable-length subnet masking.

31. 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.

32. 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.

33. The OSPF data structure that describes topology information.

34. The process of breaking a frame into pieces - sending some of the fragments - and then sending all or part of a different packet - all of which is done to reduce the delay of the second packet.

35. A type of routing protocol convergence event in which the metric for a route increases slightly over time because of the advertisement of an invalid route.

36. In MPLS VPNs - a 64-bit Extended Community path attribute attached to a BGP route for the purpose of controlling into which VRFs the route is added.

37. 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

38. In the context of SNMP - the Response command is sent by an SNMP agent - back to a manager - in response to any of the three types of Get requests - or in response to a Set request. It is also used by a manager in response to a received Inform comman

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

40. A workstation or server configured to collect and present RMON data for reporting purposes.

41. Virtual Routing and Forwarding table.

42. VTP process that prevents the flow of broadcasts and unknown unicast Ethernet frames in a VLAN from being sent to switches that have no ports in that VLAN.

43. A T1 alarm state that occurs when the receiver can no longer consistently identify the frame.

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

45. 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

46. A type of AS_PATH segment consisting of an unordered list of ASNs consolidated from component subnets of a summary BGP route.

47. A characterization of a BGP path attribute in which BGP implementations are not required to support the attribute (optional) - and for which if a router receives a route with such an attribute - the router should forward the attribute unchanged (tran

48. 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.

49. An effort to reduce the query scope with EIGRP - using route summarization or EIGRP stub routers.

50. An NTP mode in which an NTP host adjusts its clock in relation to an NTP server's clock.
