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. Per-VLAN Spanning Tree Plus.






2. A Cisco IOS configuration tool for RIP and EIGRP for which the list matches routes in routing updates - and adds a defined value to the sent or received metric for the routes. The value added to the metric is the offset.






3. The data structure used by OSPF to hold LSAs.






4. Secure Shell protocol used for character-oriented command-line access and configuration. A highly secure alternative to Telnet.






5. A Cisco IOS configuration tool that can be used to match routing updates based on a base network address - a prefix - and a range of possible masks used inside the values defined by the base network address and prefix.






6. A Cisco-proprietary feature. After a Cisco multicast router receives IGMP Join or Leave messages from hosts - it communicates to the connected Cisco switches - telling them which hosts (based on their unicast MAC addresses) have joined or left each m






7. An EIGRP message that informs neighbors about routing information. Update messages require an Ack.






8. An MPLS VPN term referring to any LSR that connects to customers to support the forwarding of unlabeled packets - as well as connecting to the MPLS network to support labeled packets - thereby making the LSR be on the edge between the provider and th






9. A set of packets in an MPLS network for which the MPLS network will apply the exact same forwarding behavior.






10. With EIGRP - a timer started when a reliable (to be acknowledged) message is transmitted. For any neighbor(s) failing to respond in its RTO - the RTP protocol causes retransmission. RTO is calculated based on SRTT.






11. A router that should not be used to forward packets between other routers. Other routers will not send Query messages to a stub router.






12. An optional contention-free 802.11 access protocol that requires the access point to poll wireless stations before they are able to send frames. Not commonly implemented.






13. The process of installing a multicast application; also referred to as launching an application.






14. An EIGRP router's reaction to an input event - leading to the use of a feasible successor or going active on a route.






15. A set of DiffServ PHBs that defines 12 DSCP values - with four queuing classes and three drop probabilities within each queuing class.






16. Differentiated Services Code Point.






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






18. Expedited Forwarding.






19. Multicast Listener Discovery.






20. 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.






21. Port Address Translation.






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






23. With routing protocols - the measurement of favorability that determines which entry will be installed in a routing table if more than one router is advertising that exact network and mask.






24. A method of obtaining an IPv6 address that uses DHCPv6. See also stateless autoconfiguration.






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






26. A method used by an IPv6 host to determine its own IP address - without DHCPv6 - by using NDP and the modified EUI-64 address format. See also stateful autoconfiguration.






27. 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






28. Network Address Translation.






29. 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






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






31. Data terminal equipment.






32. An IPv6 address format used for publicly registered IPv6 addresses.






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






34. Link Control Protocol.






35. The same thing as TCP code bits. See TCP code bits.






36. RFC 1918-defined IPv4 network numbers that are not assigned as public IP address ranges - and are not routable on the Internet. Intended for use inside enterprise networks.






37. A term used with Cisco LAN switches - referring to a DSCP value used when making QoS decisions about a frame. This value may not be the actual DSCP value in the IP header encapsulated inside the frame.






38. 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.






39. 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.






40. A network/subnet over which two or more OSPF routers have become neighbors - thereby being able to forward packets from one router to another across that network.






41. Router-Port Group Management Protocol.






42. A generic term that refers to the data structure used by a layer in a layered network architecture when sending data.






43. Any OSPF neighbor for which the database flooding process has completed.






44. The Cisco IOS feature by which special short key sequences can be used to move the cursor inside the current command line to more easily change a command.






45. 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.






46. Penultimate hop popping.






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






48. The range 233.0.0.0 through 233.255.255.255 that IANA has reserved (RFC 2770) on an experimental basis. It can be used by anyone who owns a registered autonomous system number to create 256 global multicast addresses.






49. An Internet standard (RFC 1305) that defines the messages and modes used for IP hosts to synchronize their time-of-day clocks.






50. Label switched path.
