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. The content engine in a WCCP cluster - which determines how traffic will be distributed within the cluster.






2. An optional nontransitive BGP path attribute that lists the route reflector cluster IDs through which a route has been advertised - as part of a loop-prevention process similar to the AS_PATH attribute.






3. A standard (RFC 2131) protocol by which a host can dynamically broadcast a request for a server to assign to it an IP address - along with other configuration settings - including a subnet mask and default gateway IP address. DHCP provides a great de






4. The RMON function of tracking a particular variable. RMON events trigger RMON alarms.






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






6. A well-known discretionary BGP path attribute that flags a route as being a summary route.






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






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






9. The MD5-encoded password defined by the enable secret command.






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






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






12. A message sent by a host when it wants to leave a group - addressed to the All Multicast Routers address 224.0.0.2.






13. The number of beacons that governs how often multicast frames are sent over a wireless LAN.






14. A Cisco-proprietary feature by which multiple routers can provide interface IP address redundancy so that hosts using the shared - virtual IP address as their default gateway can still reach the rest of a network even if one or more routers fail.






15. 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.






16. Alternate name for the SPF algorithm - named for its inventor - Edsger W. Dijkstra.






17. The portion of PPP focused on features that are unrelated to any specific Layer 3 protocol.






18. A Cisco IOS feature that performs deep packet inspection to classify packets based on application layer information.






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






20. The RFC 1997 name for the reserved COMMUNITY path attribute known to Cisco IOS as LOCAL_AS. (See LOCAL_AS.)






21. The operating mode of shaped round-robin that provides a low-latency queue with policing.






22. A term used with WFQ for the number assigned to a packet as it is enqueued into a WFQ. WFQ schedules the currently lowest SN packet next.






23. An FRF standard for LFI for VoFR (FRF.11) VCs - in which all voice frames are interleaved in front of data frames' fragments.






24. Boot Protocol. 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.






25. Version 6 of the IP protocol - which uses 128-bit IP addresses.






26. Challenge Handshake Authentication Protocol.






27. A BGP feature that overcomes the requirement of a full mesh of iBGP peers inside a single AS by separating the AS into multiple sub-autonomous systems.






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






29. A term referring generically to ways in which a router or switch can determine whether a particular device or user should be allowed access.






30. 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






31. Gateway Load Balancing Protocol.






32. An IOS feature in which multiple routing tables and routing forwarding instances exist in a single router - with interfaces being assigned to one of the several VRFs. This feature allows separating of routing domains inside a single router platform.






33. With EIGRP - the metric (distance) of a route as reported by a neighboring router.






34. 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






35. Defined in IEEE 802.1d - a protocol used on LAN bridges and switches to dynamically define a logical network topology that allows all devices to be reached - but prevents the formation of loops.






36. An IPv6/IPv4 tunneling method that allows isolated IPv6 domains to be connected over an IPv4 network.






37. AS number. 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. Edge LSR.






39. In two-rate policing - the second and higher rate defined to the policer.






40. Dynamic ARP Inspection.






41. A term referring to the process of applying the Message Digest 5 (MD5) algorithm to a string - resulting in another value. The original string cannot be easily computed even when the hash is known - making this process a strong method for storing pas






42. Version 4 of the IP protocol - which is the generally deployed version worldwide (at publication) - and uses 32-bit IP addresses.






43. With DiffServ - a DSCP marking and a related set of QoS actions applied to packets that have that marking.






44. Differentiated Services Code Point.






45. Protects against problems caused by unidirectional links between two switches. Watches for loss of received Hello BPDUs - in which case it transitions to a loop-inconsistent state instead of transitioning to a forwarding state.






46. The speed at which the access link is clocked. This choice affects the price of the connection and many aspects of traffic shaping and policing - compression - quality of service - and other configuration options.






47. Superframe






48. In IPv6 - a Router Advertisement message used by an IPv6 router to send information about itself to nodes and other routers connected to that router.






49. An interface on a Cisco IOS-based switch that is treated as if it were an interface on a switch.






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