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. Excess Burst.






2. Label Switch Router.






3. The IEEE standardized protocol for VLAN trunking.






4. The combination of MPLS labels and links over which a packet will be forwarded over an MPLS network - from the point of ingress to the MPLS network to the point of egress.






5. The definitions for a particular set of data variables - with those definitions following the SMI specifications. See also SMI.






6. An alternative software loaded into a Cisco router - used for low-level debugging and for password recovery.






7. A VC that is set up dynamically when needed. An SVC can be equated to a dial-on-demand connection in concept.






8. Slow Start Threshold.






9. An Internet standard authentication protocol that uses secure hashes and a three-way handshake to perform authentication over a PPP link.






10. A name used for DS1 lines inside the European TDM hierarchy.






11. A technology that sends a high-speed data stream over multiple subcarriers simultaneously. It is highly immune to multipath interference. 802.11a and 802.11g specify the use of OFDM.






12. A message sent by a multicast router - by default every 125 seconds - on each of its LAN interfaces to determine whether any host wants to receive multicast traffic for any group.






13. With some routing protocols - the time period between successive Hello messages.






14. Loss of Frame.






15. Virtual Routing and Forwarding table.






16. An Internet standard authentication protocol that uses clear-text passwords and a two-way handshake to perform authentication over a PPP link.






17. A field in the IP header that is decremented at each pass through a Layer 3 forwarding device.






18. Digital Signal Level 1.






19. Protocol Independent Multicast sparse-mode routing protocol.






20. An integer setting for EIGRP and IGRP. Any FS route whose metric is less than this variance multiplier times the successor's metric is added to the routing table - within the restrictions of the maximum-paths command.






21. Provider router.






22. The second byte of the IP header - formerly known as the ToS byte and redefined by DiffServ.






23. A term used with Cisco LAN switches - referring to a queue treated with strict-priority scheduling.






24. One of the two modes of MDRR - in which the priority queue is serviced between each servicing of the non-priority queues.






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






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






27. A router that is not an ABR or ASBR in that all of its interfaces connect to only a single OSPF area.






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






29. An EIGRP message that is used by a router to notify its neighbors when the router is gracefully shutting down.






30. Defined in FRF.11 - an FR VC that uses a slightly varied header - as compared with FRF.3 data VCs - to accommodate voice payloads directly encapsulated inside the Frame Relay LAPF header.






31. When a wireless station connects to an access point - the access point assigns an association ID (AID) to the station. Various protocols - such as power-save mode - make use of the association ID.






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






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






34. The 802.1X driver that supplies a username/password prompt to the user and sends/receives the EAPoL messages.






35. Reported distance or Route Distinguisher.






36. Part of the Cisco IOS Firewall feature set - CBAC inspects traffic using information in the higher-layer protocols being carried to decide whether to open the firewall to specific inbound traffic. CBAC supports both UDP and TCP and multiple higher-la






37. 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.






38. A name used for DS1 lines inside the North American TDM hierarchy.






39. 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.






40. A single label and link that is part of a complete LDP. See also label switched path.






41. A time value that each wireless station must set based on the duration value found in every 802.11 frame. The time value counts down and must be equal to zero before a station is allowed to access the wireless medium. The result is a collision-avoida






42. Wired Equivalent Privacy.






43. A wireless LAN that offers connections to the Internet from public places - such as airports - hotels - and coffee shops.






44. A component of the IOS IP SLA feature. An IP SLA responder is a router configured to respond to a particular IP SLA message initiated by another router - allowing the routers to work together to provide performance information including UDP jitter an






45. Used by WRED to calculate the rate at which the average queue depth changes as compared with the current queue depth. The larger the number - the slower the change in the average queue depth.






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






47. Point-to-Point Protocol.






48. The process of running the SPF algorithm against the LSDB - with the result being the determination of the current best route(s) to each subnet.






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






50. Network Time Protocol.
