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 destination VLAN for an RSPAN session.






2. Challenge Handshake Authentication Protocol.






3. 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






4. The process - defined by FRF.5 and FRF.8 - for combining ATM and FR technologies for an individual VC.






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






6. An FRF standard for LFI for data (FRF.3) VCs.






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






8. An MPLS term referring to the MPLS label just before the IP header. Also called the VPN label when implementing MPLS VPNs.






9. Differentiated Services.






10. Per-Hop Behavior.






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. 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.






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






14. The specific frequency subband on which the radio card or access point is operating. The RF channel is set in the access point or ad hoc stations.






15. Forwarding Information Base.






16. A mapping between each DSCP value and a corresponding CoS value - often used in Cisco LAN switches when performing classification for egress queuing.






17. IP Control Protocol.






18. Low-latency queuing.






19. Jargon used by STP mostly when discussing the root election process; refers to a Hello with a lower bridge ID. Sometimes refers to a Hello with the same bridge ID as another - but with better values for the tiebreakers in the election process.






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






21. 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.






22. Peak information rate.






23. In shaping and policing - commonly used to refer to the shaping or policing rate. For WAN services - a common reference to the bit rate defined in the WAN service business contract for each VC.






24. Classless interdomain routing.






25. 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.






26. 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.






27. 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.






28. An MPLS data structure used for forwarding labeled packets. The LFIB lists the incoming label - which is compared to the incoming packet's label - along with forwarding instructions for the packet.






29. The characterization of how far EIGRP Query messages flow away from the router that first notices a failed route and goes active for a particular subnet.






30. Cisco IOS router feature by which a route map determines how to forward a packet - typically based on information in the packet other than the destination IP address.






31. Web Cache Communication Protocol.






32. A characterization of a BGP path attribute in which BGP implementations are not required to support the attribute (optional) - and for which if a router receives a route with such an attribute - the router should remove the attribute before advertisi






33. The SNMP specifications - standardized in RFCs - defining the rules by which SNMP MIB variables should be defined.






34. 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






35. Uses Modular QoS CLI to control the amount and type of traffic handled by the router or switch control plane. Class maps identify traffic types - and then a service policy applied to the device control plane sets actions for each type of traffic.






36. Retransmission Timeout.






37. Feasible distance.






38. Dynamic Trunking Protocol.






39. Inverse ARP.






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






41. In switch port security - the process whereby the switch dynamically learns the MAC address(es) of the device(s) connected to a switch port - and then adds those addresses to the running configuration as allowed MAC addresses for port security.






42. The process of taking the payload inside a Layer 2 frame - including the headers of Layer 3 and above - compressing the data - and then uncompressing the data on the receiving router.






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






44. Weighted round-robin.






45. Inside telcos' original TDM hierarchy - a unit that combines multiple DS0s into a single channel






46. An NTP client that assumes that a server will send NTP broadcasts - removing the requirement for the client to have the NTP server's IP address preconfigured.






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






48. Operates in dense mode and depends on its own unicast routing protocol that is similar to RIP to perform its multicast functions.






49. A characteristic of OSPF interfaces that determines whether a DR election is attempted - whether or not neighbors must be statically configured - and the default Hello and Dead timer settings.






50. With private VLANs - a port that can send and receive frames with all other ports in the private VLAN.
