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. Network Address Translation-Protocol Translation.






2. Clear To Send.






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






4. The rate at which a policer limits the bits exiting or entering the policer.






5. In IPv6 - the Neighbor Discovery message used by an IPv6 node to send information about itself to its neighbors.






6. A Cisco-proprietary protocol that defines how to perform authentication between an authenticator (for example - a router) and an authentication server that holds a list of usernames and passwords.






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






8. When subnetting a class A - B - or C address - the subnet for which all subnet bits are binary 1.






9. A type of AS_PATH segment consisting of an ordered list of ASNs through which the route has been advertised.






10. A term referring to how a router views a BGP peer relationship - in which the peer is in another AS.






11. An SPF calculation for which a router does not need to run SPF for any LSAs inside its area - but instead runs a very simple algorithm for changes to LSAs outside its own area.






12. Ready To Send.






13. A BGP peer connection between two routers inside the same ASN - but in different confederation sub-autonomous systems.






14. A multicast routing protocol that operates in dense mode and depends on the OSPF unicast routing protocol to perform its multicast functions.






15. 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.






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






17. A BGP path attribute that lists ASNs through which the route has been advertised. The AS_PATH includes four types of segments: AS_SEQ - AS_SET - AS_CONFED_SEQ - and AS_CONFED_SET. Often - this term is used synonymously with AS_SEQ






18. An 802.1d STP transitory port state in which the port does not send or receive frames - and does not learn MAC addresses - but does wait for STP convergence and for CAM flushing by the switches in the network.






19. Weighted fair queuing.






20. A BGP term referring to an IP prefix and prefix length.






21. A router that should not be used to forward packets between other routers. Other routers will not send Query messages to a stub router.






22. Data Terminal Ready.






23. Context-Based Access Control.






24. Jargon used to refer to the first of two buckets in the dual token bucket model; its size is Bc.






25. Secure Shell protocol used for character-oriented command-line access and configuration. A highly secure alternative to Telnet.






26. Backup designated router.






27. A type of spread spectrum that spreads RF signals over the frequency spectrum by representing each data bit by a longer code. 802.11b specifies the use of DSSS.






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






29. 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.






30. Forwarding Information Base.






31. A Cisco-proprietary feature. After a Cisco multicast router receives IGMP Join or Leave messages from hosts - it communicates to the connected Cisco switches - telling them which hosts (based on their unicast MAC addresses) have joined or left each m






32. With OSPF - the timer used to determine when a neighboring router has failed - based on a router not receiving any OSPF messages - including Hellos - in this timer period.






33. Timer An STP timer that dictates how long a port should stay in the listening state and the learning state.






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






35. The operating mode of shaped round-robin that provides behavior like CBWFQ with bandwidth allocated between different traffic classes by a relative amount rather than absolute percentage of the available bandwidth.






36. In MPLS - a term used to define a label that an LSR allocates and then advertises to neighboring routers. The label is considered "local" on the router that allocates and advertises the label.






37. A Cisco IOS configuration tool - using the ip as-path access-list command - that defines a list of statements that match the AS_PATH BGP path attribute using regular expressions.






38. A Frame Relay address used in Frame Relay headers to identify the VC






39. A term relating to Cisco LAN switch tail-drop logic - in which multiple tail-drop thresholds may be assigned based on CoS or DSCP - resulting in some frames being discarded more aggressively than others.






40. Operation - Administration - and Maintenance.






41. The process of sending an infinite-metric route in routing updates when that route fails.






42. Weighted round-robin.






43. Assured Forwarding. A set of DiffServ PHBs that defines 12 DSCP values - with four queuing classes and three drop probabilities within each queuing class.






44. The destination VLAN for an RSPAN session.






45. Dynamic ARP Inspection.






46. A BGP path attribute that allows routers in one AS to set a value and advertise it into a neighboring AS - impacting the decision process in that neighboring AS. A smaller value is considered better. Also called the BGP metric.






47. The process of changing the electrical characteristics on a transmission medium - based on defined rules - to represent data.






48. A type of logic for how a router uses a default route. When a default route exists - and no more specific match is made between the destination of the packet and the routing table - the default route is used.






49. Port Aggregation Protocol.






50. Class Selector.
