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 state variable kept by a router for each known neighbor or potential neighbor.






2. 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.






3. Frame Relay Forum.






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






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






6. Network Based Application Recognition.






7. Port Aggregation Protocol.






8. A standard (RFC 3768) 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.






9. The same thing as TCP code bits. See TCP code bits.






10. A name used for DS1 lines inside the European TDM hierarchy.






11. Slow Start Threshold.






12. Defined in RFC 2091 - the extensions define how RIP may send a full update once - and then send updates only when routes change - when an update is requested - or when a RIP interface changes state from down to up.






13. Area 0; the area to which all other OSPF areas much connect in order for OSPF to work.






14. Router-Port Group Management Protocol.






15. A multicast routing protocol that operates in dense mode and depends on the OSPF unicast routing protocol to perform its multicast functions.






16. Inside telcos' original TDM hierarchy - the smallest unit of transmission at 64 kbps.






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






18. When multiple routers are connected to a subnet - only one should be sending IGMP queries. It is called a querier. IGMPv1 does not have any rules for electing a querier. In IGMPv2 and IGMPv3 - a router with the lowest interface IP address on the subn






19. Voice over Frame Relay.






20. Classless interdomain routing.






21. A TCP variable that defines the largest number of bytes allowed in a TCP segment's Data field. The calculation does not include the TCP header. With a typical IP MTU of 1500 bytes - the resulting default MSS would be 1460. TCP hosts must support an M






22. Cisco Group Management Protocol.






23. Advanced Encryption Standard A superior encryption mechanism that is part of the 802.11i standard and has much stronger security than TKIP.






24. The 32-bit number used to represent an OSPF router.






25. High Density Binary 3.






26. When a PIM-SM router switches from RPT to SPT - it sends a PIM-SM Prune message for the source and the group with the RP bit set to its upstream router on the shared tree. RFC 2362 uses the notation PIM-SM (S - G) RP-bit Prune for this message.






27. 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.






28. Defines a particular wireless LAN. The SSID configured in the radio card must match the SSID in the access point before the station can connect with the access point.






29. The first 4 bits of the first octet must be 1110. The last 28 bits are unstructured.






30. 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.






31. The process of installing a multicast application; also referred to as launching an application.






32. A term used with Cisco LAN switches - referring to a DSCP value used when making QoS decisions about a frame. This value may not be the actual DSCP value in the IP header encapsulated inside the frame.






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






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






35. On a multiaccess network - when a PIM-DM or PIM-SM router receives a Prune message - it starts a 3-second timer. If it receives a Join message on the multiaccess network from another router before the timer expires - it considers the message as an ov






36. Shaped round-robin.






37. Weighted tail drop.






38. 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.






39. 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.






40. In IP routing - a term referring to the process of forwarding packets through a router.






41. The RFC 1997 name for the reserved COMMUNITY path attribute known to Cisco IOS as LOCAL_AS. (See LOCAL_AS.)






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






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






44. An 802.1w RSTP port state in which the port is not forwarding or receiving; covers 802.1d port states disabled - blocking - and listening.






45. Switched virtual circuit.






46. An enhanced version of WEP that is part of the 802.11i standard and has an automatic key-update mechanism that makes it much more secure than WEP. TKIP is not as strong as AES in terms of data protection.






47. In the context of SNMP - the Set command is sent by an SNMP manager - to an agent - requesting that the agent set a single identified variable to the stated value. The main purpose is to allow remote configuration and remote operation - such as shutt






48. In BGP - a configuration construct in which multiple neighbors' parameters can be configured as a group - thereby reducing the length of the configuration. Additionally - BGP performs routing policy logic against only one set of Updates for the entir






49. The process of successive neighboring routers exchanging LSAs such that all routers have an identical LSDB for each area to which they are attached.






50. Point-to-Point Protocol.
