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 queuing scheduler concept - much like CQ's scheduler - in which queues are given some service in sequence. This term is often used with queuing in Cisco LAN switches.






2. 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.






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






4. Sending a message from a single source or multiple sources to selected multiple destinations across a Layer 3 network in one data stream.






5. A definition that determines the data structure and information implied by a particular LSA.






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






7. Provider edge.






8. Internal BGP.






9. In the context of SNMP - the Inform command is sent by an SNMP manager to communicate a set of variables - and their values - to another SNMP manager. The main purpose is to allow multiple managers to exchange MIB information - and work together - wi






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






11. The multicast IP address 224.0.0.5 - listened for by all OSPF routers.






12. A name used for DS3 lines inside the European TDM hierarchy.






13. A mechanism for conserving battery power in wireless stations. The access point buffers data frames destined to sleeping stations - which wake periodically to learn from information in the beacon frame whether or not data frames are waiting for trans






14. Point-to-Point Protocol over Ethernet. A convention often used as the data link protocol over Cable in which Ethernet is used as the data link protocol - but with PPP being encapsulated inside Ethernet. The combination gives the data link features of






15. Backward Explicit Congestion Notification.






16. A mapping between each DSCP value and a corresponding CoS value - often used in Cisco LAN switches when performing classification for egress queuing.






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






18. A 1-byte field in the IP header - originally defined by RFC 791 for QoS marking purposes.






19. Any occurrence that could change a router's EIGRP topology table - including a received Update or Query - a failed interface - or the loss of a neighbor.






20. Enhanced Local Management Interface.






21. Link-State Update.






22. Finish time.






23. Policing in which a single rate is metered - and packets are placed into one of three categories (conform - exceed - or violate).






24. Designated router.






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






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. Jargon referring to any queue that receives priority service - often used for queues in an LLQ configuration that have the priority command configured.






28. Router-Port Group Management Protocol.






29. Digital Signal Level 0.






30. The RMON function of sending a notification to an RMON collector or the console. Triggered by an RMON event.






31. An IPv6 address format used for publicly registered IPv6 addresses.






32. A reserved value for the BGP COMMUNITY path attribute that implies that the route should not be advertised outside the local confederation sub-AS.






33. Label switched path.






34. The portion of PPP focused on features that are unrelated to any specific Layer 3 protocol.






35. After a host receives an IGMP Query - the amount of time (default - 10 seconds) the host has to send the IGMP Report.






36. Flush timer.






37. Maximum Segment Size.






38. A T1 alarm state that occurs when a device receives a Yellow Alarm signal. This typically means that the device on the other end of the line is in a Red Alarm state.






39. Class Selector.






40. 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.






41. Tag Distribution Protocol.






42. Border Gateway Protocol.






43. Reliable Transport Protocol.






44. Cisco Group Management Protocol.






45. Receiver's advertised window.






46. A single address in each subnet for which packets sent to this address will be broadcast to all hosts in the subnet. It is the highest numeric value in the range of IP addresses implied by a subnet number and prefix/mask.






47. An event in which a new packet arrives - needing to be placed into a queue - and the queue is full






48. The most significant bit in the most significant byte of an Ethernet MAC address - its value implies that the address is a unicast MAC address (binary 0) or not (binary 1).






49. A WFQ term referring to its drop logic - which is similar to tail-drop behavior.






50. A CBWFQ and LLQ term referring to the bandwidth on an interface that is neither reserved nor allocated via a priority command.
