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






2. 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






3. 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.






4. EAP over LAN.






5. Copper cable with RJ-45 connectors in which a twisted pair at pins 1 -2 on the first end of the cable is connected to pins 3 -6 on the other end - with a second pair connected to pins 3 -6 on the first end and pins 1 -2 on the other end.






6. A standard (RFC 903) protocol by which a LAN-attached host can dynamically broadcast a request for a server to assign it an IP address. See also ARP.






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






9. Internal BGP.






10. An optimized Layer 3 forwarding path through a router or switch. CEF optimizes routing table lookup by creating a special - easily searched tree structure based on the contents of the IP routing table. The forwarding information is called the Forward






11. 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.






12. Data terminal equipment.






13. Link-State Acknowledgment.






14. An event in which a new packet arrives - needing to be placed into a queue - and the queue is full






15. The signal strength of the RF signal at the output of the radio card or access point transmitter - before being fed into the antenna. Measured in milliwatts - watts - or dBm.






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






17. Operation - Administration - and Maintenance.






18. A wireless LAN physical layer that operates at up to 11-Mbps data rates using DSSS in the 2.4-GHz band.






19. Protects against problems caused by unidirectional links between two switches. Watches for loss of received Hello BPDUs - in which case it transitions to a loop-inconsistent state instead of transitioning to a forwarding state.






20. From one perspective - DTE devices are one of two devices on either end of a communications circuit - specifically the device with less control over the communications. In Frame Relay - routers connected to a Frame Relay access link are DTE devices.






21. A wireless LAN that includes the use of access points. Infrastructure mode connects wireless users to a wired network and allows wireless users to roam throughout a facility between different access points. All 802.11 data frames in an infrastructure






22. Finish time.






23. 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






24. When subnetting a class A - B - or C address - the subnet for which all subnet bits are binary 0.






25. A queuing scheduler's logic by which - if a particular queue has packets in it - those packets always get serviced next.






26. Message Digest 5.






27. Cisco Group Management Protocol.






28. The IP address to which Label Distribution Protocol (LDP) sends LDP Hellos. Also used in IP multicast to send packets to all multicast routers.






29. In two-rate policing - the second and higher rate defined to the policer.






30. A term referring to the process of applying the Message Digest 5 (MD5) algorithm to a string - resulting in another value. The original string cannot be easily computed even when the hash is known - making this process a strong method for storing pas






31. The one VLAN on an 802.1Q trunk for which the endpoints do not add the 4-byte 802.1Q tag when transmitting frames in that VLAN.






32. A set of parameters for CBAC to perform in its traffic inspection process.






33. A DiffServ PHB that defines eight values that provide backward compatibility with IP Precedence.






34. 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.






35. The protocol used in IPv6 for many functions - including address autoconfiguration - duplicate address detection - router - neighbor - and prefix discovery - neighbor address resolution - and parameter discovery.






36. Dynamic Multipoint VPN.






37. 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






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






39. Internet Group Management Protocol.






40. Pulse code modulation.






41. Ethernet MAC address that represents all devices on the LAN.






42. A switch feature that limits the number of allowed MAC addresses on a port - with optional limits based on the actual values of the MAC addresses.






43. A conceptual model used by CB Policing when using an excess burst.






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






45. Enhances RP redundancy by providing a method for RPs to exchange multicast source information - even between multicast domains.






46. 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






47. From the perspective of one routing protocol - a route that was learned by using route redistribution.






48. Defines a particular behavior for FTP regarding the establishment of data TCP connections. In active mode - the FTP client uses the FTP PORT command - over the FTP control connection - to tell the FTP server the port on which the client should be lis






49. Layer x PDU.






50. Out of Frame.
