  • 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. The number of bytes in a queue that are removed per cycle in MDRR. Similar to byte count in the custom queuing (CQ) scheduler.

2. A type of AS_PATH segment consisting of an ordered list of ASNs through which the route has been advertised.

3. A route that is created to represent one or more smaller component routes - typically in an effort to reduce the size of routing and topology tables.

4. A single instance of STP that is applied to multiple VLANs - typically when using the 802.1Q trunking standard.

5. In the PIM-SM design - the central distribution point to which the multicast traffic is first delivered from the source designated router.

6. Prefix list.

7. Generic routing encapsulation.

8. On a serial cable - the pin lead set by the DCE to tell the DTE that the DTE is allowed send data.

9. A single label and link that is part of a complete LDP. See also label switched path.

10. Exterior Gateway Protocol.

11. A term referring to the MQC class-map command and its related subcommands - which are used for classifying packets.

12. A method that creates three thresholds per egress queue in the Cisco 3560 switch. Traffic is divided into the three queues based on CoS value - and given different likelihoods (weight) for tail drop when congestion occurs based on which egress queue

13. Controls the distribution of multicast traffic for the private multicast address range to by configuring a filter and applying it on the interfaces.

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

15. The process of taking the payload inside a Layer 2 frame - including the headers of Layer 3 and above - compressing the data - and then uncompressing the data on the receiving router.

16. Committed Burst.

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

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

19. A BGP peer connection between two routers inside the same ASN - but in different confederation sub-autonomous systems.

20. A name used for DS1 lines inside the North American TDM hierarchy.

21. From one perspective - DTE devices are one of two devices on either end of a communications circuit - specifically the device with less control over the communications. In Frame Relay - routers connected to a Frame Relay access link are DTE devices.

22. A term referring to the MQC service-policy command - which is used to enable a policy map on an interface.

23. A neighbor state that signifies the other router has reached neighbor status - having passed the parameter check.

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

25. The notation in a Cisco IOS IP routing table that identifies the route used by that router as the default route.

26. Digital Signal Level 0.

27. Multilayer Switching.

28. The combination of MPLS labels and links over which a packet will be forwarded over an MPLS network - from the point of ingress to the MPLS network to the point of egress.

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

30. An Internet standard authentication protocol that uses secure hashes and a three-way handshake to perform authentication over a PPP link.

31. Route Target.

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

33. WRED is a method of congestion avoidance that works by dropping packets before the output queue becomes completely full. WRED can base its dropping behavior on IP Precedence or DSCP values to drop low-priority packets before high-priority packets.

34. A BGP term referring to an IP prefix and prefix length.

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

36. A designated router that is directly connected with a source of the multicast group.

37. An OSPF area into which external (type 5) LSAs are not introduced by its ABRs; instead - the ABRs originate and inject default routes into the area.

38. Common Spanning Tree.

39. Shaped round-robin.

40. The SNMP specifications - standardized in RFCs - defining the rules by which SNMP MIB variables should be defined.

41. An issue whereby parts of the RF signal take different paths from the source to the destination - which causes direct and reflected signals to reach the receiver at different times - and corresponding bit errors.

42. 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.

43. An optimized Layer 3 forwarding path through a router. Fast switching optimizes routing table lookup by creating a special - easily searched table of known flows between hosts.

44. A message sent by a router - after receiving a Leave message from a host - to determine whether there are still any active members of the group. The router uses the group address as the destination address.

45. A T1 alarm state that occurs when a device has detected a local LOF/LOS/AIS condition. The device in Red alarm state then sends a Yellow alarm signal.

46. The IEEE standardized protocol for VLAN trunking.

47. Extended Superframe.

48. 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.

49. 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.

50. A generic term that refers to the data structure used by a layer in a layered network architecture when sending data.
