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. The multicast addresses assigned by IANA.






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






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






4. A protocol - defined in RFC 2865 - that defines how to perform authentication between an authenticator (for example - a router) and an authentication server that holds a list of usernames and passwords.






5. With EIGRP - for a particular route - the case in which the RD is lower than the FD.






6. A neighbor state that signifies the other router has reached neighbor status - having passed the parameter check. The FIB entry details the information needed for forwarding: the next-hop router and the outgoing interface - in an optimized mtrie stru






7. In shaping and policing - the definition of parameters that together imply the allowed rate and bursts.






8. 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






9. Another name for Superframe.






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






11. The low-order 4 bits of the configuration register. These bits direct a router to load either ROMMON software (boot field 0x0) - RXBOOT software (boot field 0x1) - or a full-function IOS image.






12. In IPv6 - the Neighbor Discovery message used by an IPv6 node to request information about a neighbor or neighbors.






13. Virtual circuit.






14. An alternative software loaded into a Cisco router - used for basic IP connectivity; most useful when Flash memory is broken and you need IP connectivity to copy a new IOS image into Flash memory.






15. A DiffServ PHB that defines eight values that provide backward compatibility with IP Precedence.






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






17. An architecture and set of documents that defines Cisco's best recommendations for how to secure a network.






18. 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.






19. A set of rules by which BGP examines the details of multiple BGP routes for the same NLRI and chooses the single best BGP route to install in the local BGP table.






20. A Cisco-proprietary feature by which multiple routers can provide interface IP address redundancy so that hosts using the shared - virtual IP address as their default gateway can still reach the rest of a network even if one or more routers fail.






21. A logical group of content engines running WCCP between them. The lead content engine determines the traffic distribution within the cluster - for optimum performance and scalability.






22. Custom queuing






23. Layer 2 payload compression.






24. One-time password.






25. A local Cisco-proprietary BGP setting that is not advertised to any peers. A larger value is considered to be better.






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






27. A 48-bit address that is calculated from a Layer 3 multicast address by using 0x0100.5E as the multicast vendor code (OUI) for the first 24 bits - always binary 0 for the 25th bit - and copying the last 23 bits of the Layer 3 multicast address.






28. An interface on a Cisco IOS-based switch that is treated as if it were an interface on a router.






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






30. The most recent standardized set of generic SNMP MIB variables - defined in RFC 1213 and updated in RFCs 2011 through 2013.






31. An EIGRP message that identifies neighbors - exchanges parameters - and is sent periodically as a keepalive function. Hellos do not require an Ack.






32. IP routing The simplest MPLS application - involving the advertisement of an IGP to learn IP routes - and LDP or TDP to advertise labels.






33. A numeric value between 0 and 32 (inclusive) that defines the number of beginning bits in an IP address for which all IP addresses in the same group have the same value. Alternative: The number of binary 1s beginning a subnet mask - written as a deci






34. Data Terminal Ready.






35. A wireless LAN physical layer that operates at up to 11-Mbps data rates using DSSS in the 2.4-GHz band.






36. Cisco IOS Embedded Event Manager - a feature that monitors events on a router and reports their results. Principally intended to increase availability - EEM provides flexible - granular detection and alerting functions.






37. The two computers use a protocol with which to communicate with the same layer on another computer. The protocol defined by each layer uses a header that is transmitted between the computers to communicate what each computer wants to do.






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






39. Differentiated Services.






40. In the PIM-SM design - the process by which a PIM-SM router can build the SPT between itself and the source of a multicast group and take advantage of the most efficient path available from the source to the router as long as it has one directly conn






41. Challenge Handshake Authentication Protocol.






42. An 802.11 frame that access points or stations in ad hoc networks send periodically so that wireless stations can discover the presence of a wireless LAN and coordinate use of certain protocols - such as power-save mode.






43. A configuration tool in Cisco IOS that allows basic programming logic to be applied to a set of items. Often used for decisions about what routes to redistribute - and for setting particular characteristics of those routes






44. 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.






45. A time value that each wireless station must set based on the duration value found in every 802.11 frame. The time value counts down and must be equal to zero before a station is allowed to access the wireless medium. The result is a collision-avoida






46. A set of DiffServ PHBs that defines 12 DSCP values - with four queuing classes and three drop probabilities within each queuing class.






47. With OSPF - the encapsulation of OSPF messages inside IP - to a router with which no common subnet is shared - for the purpose of either mending partitioned areas or providing a connection from some remote area to the backbone area.






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






49. Sent by a PIM router to its upstream router to either request that the upstream router forward the group traffic or stop forwarding the group traffic that is currently being forwarded. If a PIM router wants to start receiving the group traffic - it l






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