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. 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.






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






3. A set of four hex digits listed in an IPv6 address. Each quartet is separated by a colon.






4. 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.






5. Records client authentication and roaming events - which are sent to the CiscoWorks Wireless LAN Solution Engine (WLSE) to monitor client associations to specific access points.






6. Maximum Response Time.






7. Defined in IEEE 802.1s - a specification for multiple STP instances when using 802.1Q trunks






8. A method of collecting traffic received on a switch port or a VLAN and sending it to specific destination ports on the same switch.






9. A Frame Relay traffic shaping feature during which the shaping rate is reduced when the shaper notices congestion through the receipt of BECN or ForeSight messages.






10. 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.






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






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






13. A type of spread spectrum that spreads RF signals over the frequency spectrum by transmitting the signal at different frequencies according to a hopping pattern. One of the original 802.11 physical layers used FHSS to offer data rates of 1 and 2 Mbps






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






15. Modular QoS CLI.






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






17. After a host receives an IGMP Query - the amount of time (default - 10 seconds) the host has to send the IGMP Report.






18. Another name for Superframe.






19. A commonly used name for Multi-VRF CE.






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






21. The innermost MPLS header in an packet traversing an MPLS VPN - with the label value identifying the forwarding details for the egress PE's VRF associated with that VPN.






22. A WFQ term referring to its drop logic - which is similar to tail-drop behavior.






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. The two computers use a protocol with which to communicate with the same layer on another computer. The protocol defined by each layer uses a header that is transmitted between the computers to communicate what each computer wants to do.






25. Virtual circuit.






26. With shaping - the number of bits allowed to be sent every Tc. Also defines the size of the token bucket when Be = 0.






27. A Cisco-proprietary Layer 2 protocol that enables a router to communicate to a switch which multicast group traffic the router does and does not want to receive from the switch.






28. Modified Deficit Round-Robin.






29. 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






30. Data Terminal Ready.






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






32. Gateway Load Balancing Protocol.






33. A queuing scheduler concept - much like CQ's scheduler - in which queues are given some service in sequence. This term is often used with queuing in Cisco LAN switches.






34. A mechanism in which VLAN information can extend over another set of 802.1Q trunks by tunneling the original 802.1Q traffic with another 802.1Q tag. It allows a service provider to support transparent VLAN services with multiple customers - even if t






35. With RIP - the regular interval at which updates are sent. Each interface uses an independent timer - defaulting to 30 seconds.






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






37. Diffusing Update Algorithm.






38. 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.






39. A BGP feature that defines the IP TTL field value in packets sent between two eBGP peers. This feature is required when using IP addresses other than the interface IP address on the link between peers.






40. Defined in RFC 1293 - this protocol allows a Frame Relay-attached device to react to a received LMI "PVC up" message by announcing its Layer 3 addresses to the device on the other end of the PVC.






41. Virtual Routing and Forwarding table.






42. A 3-bit field in an ISL header used for marking frames. Also - used generically to refer to either the ISL CoS field or the 802.1Q User Priority field.






43. When multiple routers are connected to a subnet - only one should be sending IGMP queries. It is called a querier. IGMPv1 does not have any rules for electing a querier. In IGMPv2 and IGMPv3 - a router with the lowest interface IP address on the subn






44. The OSPF data structure that describes topology information.






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






46. Calculated measurement based on the actual queue depth and the previous average. Designed to allow WRED to adjust slowly to rapid changes of the actual queue depth.






47. A BGP router that - unknown to it - is aided by a route reflector server to cause all iBGP routers in an AS to learn all eBGP-learned prefixes.






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






49. A Cisco IOS queuing tool most notable for its reservation of a minimum bandwidth for each queue.






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