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. Any routing protocol that uses the concept of using the SPF algorithm with an LSDB to compute routes.






2. 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






3. An MPLS term referring to the MPLS label just before the IP header. Also called the VPN label when implementing MPLS VPNs.






4. Ready To Send.






5. With EIGRP - a route that is not a successor route - but that meets the feasibility condition; can be used when the successor route fails - without causing loops.






6. The feature in a Cisco IOS device by which a terminal session's previously typed commands are remembered - allowing the user to recall the old commands to the command line through a simple key sequence (for example - the up-arrow key).






7. An IPv6 migration strategy in which a host or router supports both IPv4 and IPv6 natively.






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






9. An OSPF external route for which internal OSPF cost is not added to the cost of the route as it was redistributed into OSPF.






10. A characterization of a BGP path attribute in which BGP implementations are not required to support the attribute (optional) - and for which if a router receives a route with such an attribute - the router should forward the attribute unchanged (tran






11. A number between 1 and 64 -511 (public) and 64 -512 and 65 -535 (private) assigned to an AS for the purpose of identifying a specific BGP domain.






12. 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.






13. The portions of PPP focused on features that are related to specific Layer 3 protocols.






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






15. The RMON function of sending a notification to an RMON collector or the console. Triggered by an RMON event.






16. With RIP - a per-route timer that increases until the router receives a routing update that confirms the route is still valid - upon which the timer is reset to 0. If the updates cease - the Invalid timer will grow - until reaching the timer setting






17. Policing in which two rates are metered - and packets are placed into one of three categories (conform - exceed - or violate).






18. Quantum value.






19. UniDirectional Link Detection.






20. 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.






21. Cisco IOS router feature by which a route map determines how to forward a packet - typically based on information in the packet other than the destination IP address.






22. An MPLS VPN term referring to the more efficient choice of popping the outer label at the second-to-last (penultimate) LSR - which then prevents the egress PE from having to perform two LFIB lookups to forward the packet.






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. As defined in RFC 3623 - graceful restart allows for uninterrupted forwarding in the event that an OSPF router's OSPF routing process must restart. The router does this by first notifying the neighbor routers that the restart is about to occur; the n






25. A set of all devices that receive broadcast frames originating from any device within the set. Devices in the same VLAN are in the same broadcast domain.






26. Jargon used by STP mostly when discussing the root election process; refers to a Hello with a lower bridge ID. Sometimes refers to a Hello with the same bridge ID as another - but with better values for the tiebreakers in the election process.






27. An FRF standard for Frame Relay-to-ATM Service Interworking in which both DTEs use Frame Relay - with ATM in between.






28. Used to reserve network resources for a flow as it traverses the network. A device that creates an RSVP reservation guarantees that it can provide the bandwidth - latency - or other resources that are requested by RSVP.






29. A Cisco IOS queuing tool that uses MQC configuration commands and reserves a minimum bandwidth for each queue.






30. A definition that determines the data structure and information implied by a particular LSA.






31. A field within a route entry in a routing update - used to associate a generic number with the route. It is used when passing routes between routing protocols - allowing an intermediate routing protocol to pass information about a route that is not n






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






33. A BGP feature that defines the IP TTL field value in packets sent between two eBGP peers. This feature is required when using IP addresses other than the interface IP address on the link between peers.






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






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






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






37. A term referring to the processes and bits in the data stream used to manage the Telco TDM hierarchy.






38. Defined in RFC 826 - a protocol used on LANs so that an IP host can discover the MAC address of another device that is using a particular IP address.






39. WRED compares this setting to the average queue depth to decide whether packets should be discarded. No packets are discarded if the average queue depth falls below this minimum threshold.






40. Defined in RFC 3748 - the protocol used by IEEE 802.1X for exchanging authentication information.






41. A characteristic of OSPF interfaces that determines whether a DR election is attempted - whether or not neighbors must be statically configured - and the default Hello and Dead timer settings.






42. An effort to reduce the query scope with EIGRP - using route summarization or EIGRP stub routers.






43. In MPLS - a term used to define a label that an LSR allocates and then advertises to neighboring routers. The label is considered "local" on the router that allocates and advertises the label.






44. A type of OSPF packet used to discover neighbors - check for parameter agreement - and monitor the health of another router.






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






46. Three core security functions.






47. 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.






48. Multilink PPP.






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






50. In SNMP - the process of a manager using successive GetNext and GetBulk commands to discover the exact MIB structure supported by an SNMP agent. The process involves the manager asking for each successive MIB leaf variable.
