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. Route Target.






2. Out of Frame.






3. A vendor consortium that formerly worked to further Frame Relay common vendor standards.






4. The second byte of the IP header - formerly known as the ToS byte and redefined by DiffServ.






5. The second most significant bit in the most significant byte of an Ethernet MAC address - a value of binary 0 implies that the address is a Universally Administered Address (UAA) (also known as Burned-In Address [BIA]) - and a value of binary 1 impli






6. Neighbor Discovery Protocol.






7. With a routing update - or routing table entry - the portion of a route that defines the next router to which a packet should be sent to reach the destination subnet. With routing protocols - the Next Hop field may define a router other than the rout






8. A component of the IOS IP SLA feature. An IP SLA responder is a router configured to respond to a particular IP SLA message initiated by another router - allowing the routers to work together to provide performance information including UDP jitter an






9. 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






10. An IPv6 address type that is used by a number of hosts in a network that are providing the same service. Hosts accessing the service are routed to the nearest host in an anycast environment based on routing protocol metrics.






11. With EIGRP - for a particular route - the case in which the RD is lower than the FD.






12. 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.






13. In OSPF - a router that is prepared to take over the designated router.






14. A reserved value for the BGP COMMUNITY path attribute that implies that the route should not be advertised outside the local AS.






15. 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.






16. A name used for DS3 lines inside the North American TDM hierarchy.






17. A technology that enables frequency reuse. Two variants exist: frequency hopping (FHSS) and direct sequence (DSSS). Both techniques spread the signal power over a relatively wide portion of the frequency spectrum over time - to reduce interference be






18. An FRF standard for payload compression.






19. A DiffServ PHB - based on DSCP EF (decimal 46) - that provides low-latency queuing behavior as well as policing protection to prevent EF traffic from starving queues for other types of traffic.






20. A term generally describing characteristics about BGP paths that are advertised in BGP Updates.






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






22. A component that interfaces with a phone using IP and provides connections to the Public Switched Telephone Network (PSTN).






23. Smoothed Round-Trip Time.






24. Modified Deficit Round-Robin.






25. Inter-Switch Link.






26. A field in the IP header that is decremented at each pass through a Layer 3 forwarding device.






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






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






29. 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






30. Receiver's advertised window.






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






32. In shaping and policing - the definition of parameters that together imply the allowed rate and bursts.






33. A BGP path attribute that implies how the route was originally injected into some router's BGP table.






34. Used by WRED to calculate the rate at which the average queue depth changes as compared with the current queue depth. The larger the number - the slower the change in the average queue depth.






35. With Spanning Tree Protocol - the single port on each LAN segment from which the best Hello BPDU is forwarded.






36. A Cisco IOS queuing tool that uses MQC configuration commands and reserves a minimum bandwidth for each queue.






37. Defined in RFC 2289 - a mechanism by which a shared key and a secret key together feed into a hash algorithm - creating a password that is transmitted over a network. Because the shared key is not reused - the hash value is only valid for that indivi






38. Voice over Frame Relay.






39. EIGRP jargon meaning that EIGRP has placed a route into active status.






40. Classless interdomain routing.






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






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






43. Weighted tail drop.






44. 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






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






46. A reserved value for the BGP COMMUNITY path attribute that implies that the route should not be advertised outside the local confederation sub-AS.






47. Network Address Translation.






48. The single port on each nonroot switch upon which the best Hello BPDU is received.






49. A method of applying a mathematical formula - with input including a private key - the message contents - and sometimes a shared text string - with the resulting digest being included with the message. The sender and the receiver perform the same mat






50. Reliable Transport Protocol.
