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. IP Control Protocol.






2. An MPLS LSR that can forward and receive both labeled and unlabeled packets.






3. In IPv6 DNS - the IPv6 equivalent of an IPv4 DNS A record.






4. Regeneration of the Layer 2 encapsulation removed from frames forwarded in a SPAN session.






5. Extensible Authentication Protocol.






6. A Cisco IOS queuing tool most notable for its automatic classification of packets into separate per-flow queues.






7. Label Forwarding Information Base.






8. 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.






9. Dynamic Trunking Protocol.






10. A bit in the LAPF Frame Relay header that - when set to 1 - implies that the frame has experienced congestion.






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






12. Rapid Spanning Tree Protocol.






13. 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.






14. Gateway Load Balancing Protocol.






15. The list of entries learned by the switch DHCP snooping feature. The entries include the MAC address used as the device's DHCP client address - the assigned IP address - the VLAN - and the switch port on which the DHCP assignment messages flowed.






16. 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.






17. An address type in IPv6 networks that is used only on the local link and never beyond that scope.






18. A calculated TCP variable - used along with the TCP CWND variable - to dictate a TCP sender's behavior when it recognizes packet loss. As CWND grows after packet loss - the TCP sender increases CWND based on Slow Start rules - until CWND grows to be






19. A type of OSPF NSSA area for which neither external (type 5) LSAs are introduced - nor type 3 summary LSAs; instead - the ABRs originate and inject default routes into the area. External routes can be injected into a totally NSSA area.






20. With EIGRP - the metric value for the lowest-metric route to a particular subnet.






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






22. A set of parameters for CBAC to perform in its traffic inspection process.






23. An OSPF timer that determines how long an LSA can remain in the LSDB without having heard a reflooded copy of the LSA.






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






25. A switch feature with which the switch watches ARP messages - determines if those messages may or may not be part of some attack - and filters those that look suspicious.






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






27. A term generally describing characteristics about BGP paths that are advertised in BGP Updates.






28. 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






29. Feasible distance.






30. Message Digest 5.






31. A standard (RFC 951) protocol by which a LAN-attached host can dynamically broadcast a request for a server to assign it an IP address - along with other configuration settings - including a subnet mask and default gateway IP address.






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






33. Protocol Independent Multicast sparse-mode routing protocol.






34. A BGP message that includes withdrawn routes - path attributes - and NLRI.






35. Quantum value.






36. The Frame Relay protocol used between a DCE and DTE to manage the connection. Signaling messages for SVCs - PVC Status messages - and keepalives are all LMI messages.






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






38. 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.






39. The router in a VRRP group that is currently actively forwarding IP packets. Conceptually the same as an HSRP Active router.






40. Access Control Server. A term referring generically to a server that performs many AAA functions. It also refers to the software product Cisco Secure Access Control Server.






41. 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






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






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






44. A predefined VC. A PVC can be equated to a leased line in concept.






45. Modified Deficit Round-Robin.






46. Hot Standby Router Protocol.






47. A message sent by each host - either in response to a router query or on its own - to all multicast groups for which it would like to receive multicast traffic. The destination address on the Report is 224.0.0.22 - and a host can specify the source a






48. In MQC and CB Policing - a configuration style by which - for one category of packets (conform - exceed - or violate) - more than one marking action is defined for a single category. For example - marking DSCP and DE.






49. A term referring generically to a server that performs many AAA functions. It also refers to the software product Cisco Secure Access Control Server.






50. 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
