  • 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 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.

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

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

4. Weighted round-robin.

5. In an IOS confederation configuration - the actual ASN as seen by eBGP peers.

6. 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.

7. Ethernet MAC address that represents all devices on the LAN.

8. With EIGRP - the metric (distance) of a route as reported by a neighboring router.

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

10. Bipolar Violation.

11. A standard (RFC 951) protocol by which a LAN-attached host can dynamically broadcast a request for a server to assign it an IP address - along with other configuration settings - including a subnet mask and default gateway IP address.

12. The term to describe a router that is neither the DR nor the BDR on a subnet that elects a DR and BDR.

13. A basic form of traffic shaping that is applied to an interface or subinterface. By default - it shapes all traffic leaving the interface - but can be modified by using an access control list. The access list controls only what traffic is shaped; GTS

14. Slow Start Threshold.

15. A Cisco-proprietary feature by which multiple routers can provide interface IP address redundancy - as well as cause a set of clients to load-balance their traffic across multiple routers inside the GLBP group.

16. A method for how a TCP sender grows its calculated CWND variable - thereby growing the allowed window for the connection. Congestion Avoidance grows CWND linearly.

17. Cisco-proprietary STP feature in which a switch port monitors for STP BPDUs of any kind - err-disabling the port upon receipt of any BPDU.

18. A Cisco-proprietary messaging protocol implemented in WAN switches that can be used to signal network status - including congestion - independent of end-user frames and cells.

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

20. Priority queue and priority queuing.

21. 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.

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

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

24. Class Selector.

25. Bootstrap Router.

26. A message sent by a multicast router - by default every 125 seconds - on each of its LAN interfaces to determine whether any host wants to receive multicast traffic for any group.

27. An SPF calculation for which a router does not need to run SPF for any LSAs inside its area - but instead runs a very simple algorithm for changes to LSAs outside its own area.

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

29. From the perspective of one routing protocol - a route that was learned by using route redistribution.

30. Structure of Management Information.

31. Label Forwarding Information Base.

32. The information maintained by a router for each multicast entry in its multicast routing table - such as incoming interface - outgoing interface list - Uptime timer - Expire timer - etc.

33. Network Address Translation-Protocol Translation.

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

35. A type of IPv4 and IPv6 traffic designed primarily to provide one-to-many connectivity but unlike broadcast - has the capability to control the scope of traffic distribution.

36. Software-based collection and reporting tool for data reported by NetFlow.

37. A category used by a policer to classify packets relative to the traffic contract. The bit rate implied by all conforming packets is within the traffic contract.

38. 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.

39. An FRF standard for payload compression.

40. Aka Rapid Per-VLAN Spanning Tree Plus.

41. Variable-length subnet masking.

42. Digital Signal Level 0.

43. A term referring generically to ways in which a router or switch can determine whether a particular device or user should be allowed access.

44. Label switched path.

45. Inside telcos' original TDM hierarchy - a unit that combines multiple DS0s into a single channel

46. Type of Service byte.

47. A possible side effect of a scheduler that performs strict-priority scheduling of a queue - which can result in lower-priority queues getting little or no service.

48. Low-latency queuing.

49. The process of running the SPF algorithm against the LSDB - with the result being the determination of the current best route(s) to each subnet.

50. Virtual Router Redundancy Protocol.
