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. Instead of advertising all routes out a particular interface - the routing protocol omits the routes whose outgoing interface field matches the interface out which the update would be sent.






2. Challenge Handshake Authentication Protocol.






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






4. 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.






5. The portions of PPP focused on features that are related to specific Layer 3 protocols.






6. Class-Based Marking.






7. A term referring generically to a server that performs many AAA functions. It also refers to the software product Cisco Secure Access Control Server.






8. Slow Start Threshold.






9. A reserved value for the BGP COMMUNITY path attribute that implies that the route should not be advertised to any other peer.






10. Clear To Send.






11. Any routing protocol that uses the concept of using the SPF algorithm with an LSDB to compute routes.






12. 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






13. 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.






14. Neighbor Discovery Protocol.






15. In PIM-SM - the path of the group traffic that flows from the RP to the routers that need the traffic. It is also called the root-path tree (RPT) - because it is rooted at the RP.






16. The definitions for a particular set of data variables - with those definitions following the SMI specifications. See also SMI.






17. Superframe






18. A network/subnet to which only one OSPF router is connected.






19. An E-LSR in an MPLS VPN network whose role in a particular discussion is to receive unlabeled packets over customer links and then forward the packets as labeled packets into the MPLS network.






20. A method of providing dynamically configured spoke-to-spoke VPN connectivity in a hub-and-spoke network that significantly reduces configuration required on the spoke routers compared to traditional IPsec VPN environments.






21. In BGP - a feature in which BGP routes cannot be considered to be a best route to reach an NLRI unless that same prefix exists in the router's IP routing table as learned via some IGP.






22. The router in a VRRP group that is currently actively forwarding IP packets. Conceptually the same as an HSRP Active router.






23. 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






24. A name used for DS3 lines inside the European TDM hierarchy.






25. An EIGRP router's reaction to an input event - leading to the use of a feasible successor or going active on a route.






26. 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.






27. In the context of SNMP - the Trap command is sent by an SNMP agent - to a manager - when the agent wants to send unsolicited information to the manager. Trap is not followed by a Response message from the receiving SNMP manager.






28. A protection against problems caused by unidirectional links between two switches. Uses messaging between switches to detect the loop - err-disabling the port when the link is unidirectional.






29. Inside telcos' original TDM hierarchy - the smallest unit of transmission at 64 kbps.






30. Network Address Translation-Protocol Translation.






31. With private VLANs - a secondary VLAN in which the ports can send and receive frames with each other - but not with ports in other secondary VLANS.






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






33. A protocol - defined in RFC 2865 - 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.






34. Database Description.






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






36. An 802.1w RSTP port state in which the port is not forwarding or receiving; covers 802.1d port states disabled - blocking - and listening.






37. Ethernet process by which devices attached to the same cable negotiate their speed and the duplex settings over the cable.






38. Shaped round-robin.






39. IP Control Protocol.






40. Priority queue and priority queuing.






41. A Cisco-proprietary feature by which multiple routers can provide interface IP address redundancy so that hosts using the shared - virtual IP address as their default gateway can still reach the rest of a network even if one or more routers fail.






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






43. The most significant bit in the most significant byte of an Ethernet MAC address - its value implies that the address is a unicast MAC address (binary 0) or not (binary 1).






44. A calculation of the length of the AS_PATH PA - which includes 1 for each number in the AS_SEQ - 1 for an entire AS_SET segment - and possibly other considerations.






45. Variable-length subnet masking.






46. Cisco Wireless LAN Solution Engine.






47. External BGP.






48. The process of taking routes known through one routing protocol and advertising those routes with another routing protocol.






49. 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.






50. A Cisco-proprietary STP implementation - created many years before IEEE 802.1s and 802.1w - that speeds convergence and allows for one STP instance for each VLAN.
