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. VTP process that prevents the flow of broadcasts and unknown unicast Ethernet frames in a VLAN from being sent to switches that have no ports in that VLAN.






2. A state variable kept by a router for each known neighbor or potential neighbor.






3. A basic form of traffic shaping that is applied to an interface or subinterface. By default - it shapes all traffic leaving the interface - but can be modified by using an access control list. The access list controls only what traffic is shaped; GTS






4. 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.






5. A subset of a classful IP network - as defined by a subnet mask - which used to address IP hosts on the same Layer 2 network in much the same way as a classful network is used.






6. An MPLS term referring to any device that can forward packets that have MPLS labels.






7. The process of forwarding packets through a router. Also call IP routing.






8. An EIGRP message that is used to ask neighboring routers to verify their route to a particular subnet. Query messages require an Ack.






9. Smoothed Round-Trip Time.






10. The IP address to which Label Distribution Protocol (LDP) sends LDP Hellos. Also used in IP multicast to send packets to all multicast routers.






11. A T1 alarm state that occurs when the receiver can no longer consistently identify the frame. See LOF.






12. A wireless LAN physical layer that operates at up to 11-Mbps data rates using DSSS in the 2.4-GHz band.






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






14. Wired Equivalent Privacy.






15. A queuing scheduler's logic by which - if a particular queue has packets in it - those packets always get serviced next.






16. Aka network layer reachability information.






17. 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.






18. A security standard that includes both TKIP and AES and was ratified by the Wi-Fi Alliance.






19. Also known as triggered updates.






20. When subnetting a class A - B - or C address - the subnet for which all subnet bits are binary 0.






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






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






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






24. A Cisco IOS queuing tool most notable for its scheduler - which always services the high-priority queue over all other queues.






25. Cisco-proprietary STP feature in which a switch port monitors for STP BPDUs of any kind - err-disabling the port upon receipt of any BPDU.






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






27. A type of IPv4 and IPv6 traffic designed primarily to provide one-to-many connectivity but unlike broadcast - has the capability to control the scope of traffic distribution.






28. Quantum value.






29. The process by which neighboring OSPF routers examine their Hello messages and elect the DR. The decision is based on priority (highest) - or RID (highest) if priority is a tie.






30. On a serial cable - the pin lead set by the DCE to tell the DTE that the DTE is allowed send data.






31. A switch feature that examines incoming frames - comparing the source IP and MAC addresses to the DHCP snooping binding database - filtering frames whose addresses are not listed in the database for the incoming interface.






32. In the context of SNMP - the Response command is sent by an SNMP agent - back to a manager - in response to any of the three types of Get requests - or in response to a Set request. It is also used by a manager in response to a received Inform comman






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






34. The multicast IP address 224.0.0.5 - listened for by all OSPF routers.






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






36. As defined in RFCs 2765 and 2766 - a method of translating between IPv4 and IPv6 that removes the need for hosts to run dual protocol stacks. NAT-PT is an alternative to tunneling IPv6 over an IPv4 network - or vice versa.






37. Each 802.11 station passively monitors each RF channel for a specific amount of time and listens for beacons. Stations use the signal strengths of found beacons to determine the access point or ad hoc network with which to attempt association.






38. A specification for the 64-bit interface ID in an IPv6 address - composed of the first half of a MAC address - hex FFFE - and the last half of the MAC.






39. In OSPF - a number assigned to each LSA - ranging from 0x80000001 and wrapping back around to 0x7FFFFFFF - which is used to determine which LSA is most recent.






40. UniDirectional Link Detection.






41. The process of forwarding packets through a router. Also called IP forwarding.






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






43. An IPv6/IPv4 tunneling method that is designed for transporting IPv6 packets within a site where a native IPv6 infrastructures is not available.






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






45. The most recent standardized set of generic SNMP MIB variables - defined in RFC 1213 and updated in RFCs 2011 through 2013.






46. Link-state advertisement.






47. The IP address used by hosts as the default gateway in a VRRP configuration. This address is shared by two or more VRRP routers - much as HSRP works.






48. 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






49. Policing in which a single rate is metered - and packets are placed into one of two categories (conform or exceed).






50. The notation in a Cisco IOS IP routing table that identifies the route used by that router as the default route.
