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 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.






2. A tunneling protocol that can be used to encapsulate many different protocol types - including IPv4 - IPv6 - IPsec - and others - to transport them across a network.






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






4. 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.






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






6. An attack by which the attacker initiates many TCP connections to a server - but does not complete the TCP connections - by simply not sending the third segment normally used to establish the connection. The server may consume resources and reject ne






7. Router Advertisement.






8. A term referring to the MQC policy-map command and its related subcommands - which are used to apply QoS actions to classes of packets.






9. Protocol Independent Multicast sparse-mode routing protocol.






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






11. When a Query is received from a router - each host randomly picks a time between 0 and the Maximum Response Time period to send a Report. When the host with the smallest time period first sends the Report - the rest of the hosts suppress their report






12. On a serial cable - the pin lead set by the DCE to imply a working link.






13. 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.






14. An 802.1d STP port state in which the port sends and receives frames.






15. A wireless LAN physical layer that is backward compatible with 802.11b and operates at up to 54-Mbps data rates using OFDM in the 2.4-GHz band.






16. A Cisco-proprietary protocol - used by LAN switches to communicate VLAN configuration.






17. Loss of Frame.






18. Data Carrier Detect.






19. Structure of Management Information.






20. An OSPF router that connects to the backbone area and to one or more non-backbone area.






21. The PPP function for fragmenting packets - plus interleaving delay-sensitive later-arriving packets between the fragments of the first packet.






22. Also known as triggered updates.






23. Weighted random early detection.






24. Modified Deficit Round-Robin.






25. EAP over LAN.






26. The Cisco IOS Router IP Traffic Export feature - intended for intrusion detection - exports IP traffic that has signs of an attack - such as duplicate IP packets simultaneously received on two or more of a router's interfaces.






27. 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.






28. Network Time Protocol.






29. Link Access Procedure for Frame-Mode Bearer Services.






30. A WRED process by which WRED discards all newly arriving packets intended for a queue - based on whether the queue's maximum threshold has been exceeded.






31. Layer 2 payload compression.






32. In OSPF - a router that is prepared to take over the designated router.






33. A possible side effect of a scheduler that performs strict-priority scheduling of a queue - which can result in lower-priority queues getting little or no service.






34. The RFC-standard MPLS protocol used to advertise the binding (mapping) information about each particular IP prefix and associated label. See also TDP.






35. Management Information Base.






36. An ITU standard Frame Relay header - including the DLCI - DE - FECN - and BECN bits in the LAPF header - and a frame check in the LAPF trailer.






37. The rate at which a shaper limits the bits exiting the shaper.






38. Operation - Administration - and Maintenance.






39. Another term for summary route.






40. Sent by a PIM-DM or PIM-SM router when it receives a multicast packet for a group on a LAN interface that is in the outgoing interface list for the group; includes the administrative distance of the unicast routing protocol used to learn the network






41. 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






42. A process on a computing device that issues requests for SNMP MIB variables from SNMP agents - receives and processes the MIB data - and accepts unsolicited Trap messages from SNMP agents.






43. A type of logic for how a router uses a default route. When a default route exists - and no more specific match is made between the destination of the packet and the routing table - the default route is used.






44. Jargon referring to the minimum value to which adaptive shaping will lower the shaping rate.






45. Slow Start Threshold.






46. In BGP - either external BGP (eBGP) - confederation eBGP - or internal BGP (iBGP). The term refers to a peer connection - and whether the peers are in different ASs (eBGP) - different confederation sub-ASs (confederation eBGP) - or in the same AS (iB






47. In MPLS VPNs - an entity in a single router that provides a means to separate routes in different VPNs. The VRF includes per-VRF instances of routing protocols - a routing table - and an associated CEF FIB.






48. The portion of PPP focused on negotiating IP features






49. 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.






50. Backward Explicit Congestion Notification.
