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 Cisco-proprietary messaging protocol used to negotiate the dynamic creation of PortChannels (EtherChannels) and to choose which ports can be placed into an EtherChannel.






2. The first 6 bits of the DS field - used for QoS marking.






3. An MPLS application that allows the MPLS network to connect to multiple different IP networks - with overlapping IP addresses - and provide IP connectivity to those multiple networks.






4. A type of OSPF stub area that - unlike stub areas - can inject external routes into the NSSA area.






5. Another name for Superframe.






6. Another name for 802.1Q-in-Q. See 802.1Q-in-Q.






7. A 3-bit field in the first 3 bits of the ToS byte in the IP header - used for QoS marking.






8. A BGP ASN whose value is between 64 -512 and 65 -535. These values are not assigned for use on the Internet - and can be used for private purposes - typically either within confederations or by ISPs to hide the ASN used by some customers.






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






10. Edge LSR.






11. 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.






12. A Layer 3 forwarding path through a router that does not optimize the forwarding path through the router.






13. Finish time.






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






15. A Cisco IOS configuration tool for RIP and EIGRP for which the list matches routes in routing updates - and adds a defined value to the sent or received metric for the routes. The value added to the metric is the offset.






16. A router that should not be used to forward packets between other routers. Other routers will not send Query messages to a stub router.






17. An NTP mode in which two or more NTP servers mutually synchronize their clocks.






18. Cisco-proprietary STP feature in which an access layer switch is configured to be unlikely to become Root or to become a transit switch. Also - convergence upon the loss of the switch's Root Port takes place in a few seconds.






19. Voice over Frame Relay.






20. Access Control Entry. An individual line in an ACL.






21. A queue created by Cisco IOS as a result of the configuration of a queuing tool.






22. The characterization of how far EIGRP Query messages flow away from the router that first notices a failed route and goes active for a particular subnet.






23. Inside telcos' original TDM hierarchy - a unit that combines multiple DS1s into a single channel






24. DCE devices are one of two devices on either end of a communications circuit - specifically the device with more control over the communications. Frame Relay switches are DCE devices. DCEs are also known as data circuit-terminating equipment (DTE).






25. A calculation of the length of the AS_PATH PA - which includes 1 for each number in the AS_SEQ - 1 for an entire AS_SET segment - and possibly other considerations.






26. Defined in IEEE 802.1w - a specification to enhance the 802.1d standard to improve the speed of STP convergence.






27. 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






28. In the context of SNMP - the Get command is sent by an SNMP manager - to an agent - requesting the value of a single MIB variable identified in the request. The Get request identifies the exact variable whose value the manager wants to retrieve. Intr






29. 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






30. 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.






31. The mandatory contention-based 802.11 access protocol that is also referred to as CSMA/CA.






32. Allows the router to act as an inline IPS - doing deep packet inspection.






33. A network/subnet over which two or more OSPF routers have become neighbors - thereby being able to forward packets from one router to another across that network.






34. A serial-line encoding standard that substitutes Bipolar Violations in a string of eight binary 0s to provide enough signal transitions to maintain synchronization.






35. With EIGRP - the route to each destination for which the metric is the lowest of all known routes to that network.






36. A type of OSPF packet used to acknowledge LSU packets.






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






38. The process of taking the IP and TCP headers of a packet - compressing them - and then uncompressing them on the receiving router.






39. Cisco Wireless LAN Solution Engine.






40. An early T1 framing standard.






41. Jargon used to refer to the second of two buckets in the dual token bucket model; its size is Be.






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






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






44. A workstation or server configured to collect and present RMON data for reporting purposes.






45. Designated router.






46. A wireless LAN that includes the use of access points. Infrastructure mode connects wireless users to a wired network and allows wireless users to roam throughout a facility between different access points. All 802.11 data frames in an infrastructure






47. 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






48. Multilayer Switching.






49. With private VLANs - a secondary VLAN in which the ports can send and receive frames with each other - but not with ports in other secondary VLANS.






50. Frequency hopping spread spectrum.
