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. Designed to solve the problems of multicast duplication and multicast routing loops. For every multicast packet received - a multicast router examines its source IP address - consults its unicast routing table - determines which interface it would us






2. An EIGRP message that is used to ask neighboring routers to verify their route to a particular subnet. Query messages require an Ack.






3. An optional transitive BGP path attribute that - for a summary route - lists the BGP RID and ASN of the router that created the summary.






4. A BGP neighbor state in which the BGP neighbors have stabilized and can exchange routing information using BGP Update messages.






5. A security standard that includes both TKIP and AES and was ratified by the Wi-Fi Alliance.






6. A group of devices on one or more LANs that are configured (using management software) so that they can communicate as if they were attached to the same wire - when - in fact - they are located on a number of different LAN segments. Because VLANs are






7. 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






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






9. A NAT term describing an IP address representing a host that resides inside the enterprise network - with the address being used in packets outside the enterprise network.






10. Enhanced Local Management Interface.






11. Network Layer Protocol ID is a field in the RFC 2427 header that is used as a Protocol Type field in order to identify the type of Layer 3 packet encapsulated inside a Frame Relay frame.






12. Each 802.11 station passively monitors each RF channel for a specific amount of time and listens for beacons. Stations use the signal strengths of found beacons to determine the access point or ad hoc network with which to attempt association.






13. An MPLS VPN term referring to a router at a customer site that does not implement MPLS.






14. On a serial cable - the pin lead set by the DCE to imply that the DCE is ready to signal using pin leads






15. Layer x PDU.






16. A Cisco IOS feature that provides reporting information to a NetFlow aggregator based on traffic flows.






17. 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






18. Orthogonal frequency division multiplexing.






19. Removing unwanted VLANs from a Layer 2 path.






20. Virtual Router Redundancy Protocol.






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






22. IP multicast address range from 224.0.0.0 through 239.255.255.255.






23. An IPv6 address type that is used by a number of hosts in a network that are providing the same service. Hosts accessing the service are routed to the nearest host in an anycast environment based on routing protocol metrics.






24. A routing protocol feature by which the routing update includes only routes that have changed - rather than include the entire set of routes.






25. Data Terminal Ready.






26. The one VLAN on an 802.1Q trunk for which the endpoints do not add the 4-byte 802.1Q tag when transmitting frames in that VLAN.






27. A set of QoS RFCs that redefines the IP header's ToS byte - and suggests specific settings of the DSCP field and the implied QoS actions based on those settings.






28. Defined in IEEE 802.1s - a specification for multiple STP instances when using 802.1Q trunks






29. The original standardized set of generic SNMP MIB variables - defined in RFC 1158.






30. An optional transitive BGP path attribute used to store 32-bit decimal values. Used for flexible grouping of routes by assigning the group the same COMMUNITY value. Other routers can apply routing policies based on the COMMUNITY value. Used in a larg






31. Label switched path.






32. Any other router - sharing a common data link - with which a router exchanges Hellos - and for which the parameters in the Hello pass the parameter-check process.






33. 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.






34. Operation - Administration - and Maintenance.






35. With EIGRP - the metric (distance) of a route as reported by a neighboring router.






36. Committed Burst.






37. A set of all devices for which any frame sent by one of the devices would collide with any frames transmitted at the same time by any of the other devices in the set.






38. A protocol used for reliable multicast and unicast transmissions. Used by EIGRP.






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






40. Protocol Independent Multicast dense-mode routing protocol.






41. 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.






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






43. Service set identifier.






44. A category used by a policer to classify packets relative to the traffic contract. The bit rate implied by all conforming packets is within the traffic contract.






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






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






47. Defines a particular behavior for FTP regarding the establishment of TCP data connections. In passive mode - an FTP server uses the FTP PORT command - over the FTP control connection - to tell the FTP client the port on which the server will be liste






48. Structure of Management Information.






49. The 802.1X function implemented by a switch - in which the switch translates between EAPoL and RADIUS messages in both directions - and enables/disables ports based on the success/failure of authentication.






50. A type of OSPF packet - used to communicate LSAs to another router.
