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. A single address in each subnet for which packets sent to this address will be broadcast to all hosts in the subnet. It is the highest numeric value in the range of IP addresses implied by a subnet number and prefix/mask.






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






3. A term referring to the MQC service-policy command - which is used to enable a policy map on an interface.






4. The process of running the SPF algorithm against the LSDB - with the result being the determination of the current best route(s) to each subnet.






5. A 64-bit extension to the BGP NLRI field - used by MPLS for the purpose of making MPLS VPN customer routes unique in spite of the possibility of overlapping IPv4 address spaces in different customer networks.






6. Committed information rate.






7. Excess Burst.






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






9. Router Advertisement.






10. In IPv6 - the Neighbor Discovery message used by an IPv6 node to request information about a neighbor or neighbors.






11. Virtual Router Redundancy Protocol.






12. The process of taking the IP - UDP - and RTP headers of a voice or video packet - compressing them - and then uncompressing them on the receiving router.






13. Network Address Translation-Protocol Translation.






14. An 802.1d STP port state in which the port has been administratively disabled.






15. A problem that occurs when an AS does not run BGP on all routers - with synchronization disabled. The routers running BGP may believe they have working routes to reach a prefix - and forward packets to internal routers that do not run BGP and do not






16. The ASN assigned to a confederation sub-AS.






17. Any occurrence that could change a router's EIGRP topology table - including a received Update or Query - a failed interface - or the loss of a neighbor.






18. A 48-bit address that is calculated from a Layer 3 multicast address by using 0x0100.5E as the multicast vendor code (OUI) for the first 24 bits - always binary 0 for the 25th bit - and copying the last 23 bits of the Layer 3 multicast address.






19. An OSPF external route for which internal OSPF cost is not added to the cost of the route as it was redistributed into OSPF.






20. 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).






21. The RMON function of tracking a particular variable. RMON events trigger RMON alarms.






22. Voice over Frame Relay.






23. A BGP router that forwards iBGP-learned routes to other iBGP routers.






24. Defined in RFC 826 - a protocol used on LANs so that an IP host can discover the MAC address of another device that is using a particular IP address.






25. A wireless LAN that only includes wireless users and no access points. 802.11 data frames in an ad hoc network travel directly between wireless users.






26. 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.






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






28. Link Control Protocol.






29. VLAN Trunking Protocol.






30. An IP variable that defines the largest size allowed in an IP packet - including the IP header. IP hosts must support an MTU of at least 576 bytes.






31. 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.






32. Challenge Handshake Authentication Protocol.






33. 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.






34. An OSPF area into which external (type 5) LSAs are not introduced by its ABRs; instead - the ABRs originate and inject default routes into the area.






35. Weighted tail drop.






36. Cisco Express Forwarding.






37. Reliable Transport Protocol.






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






39. Data communications equipment.






40. A method of collecting traffic received on a switch port or a VLAN and sending it to specific destination ports on the same switch.






41. A route that is created to represent one or more smaller component routes - typically in an effort to reduce the size of routing and topology tables.






42. Protocol Independent Multicast dense-mode routing protocol.






43. 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






44. 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.






45. A 3-bit field in an 802.1Q header used for marking frames.






46. An Internet standard serial data-link protocol - used on synchronous and asynchronous links - that provides data-link framing - link negotiation - Layer 3 interface features - and other functions.






47. Internet Group Management Protocol.






48. A routing protocol feature for which the routing protocol sends routing updates immediately upon hearing about a changed route - even though it may normally only send updates on a regular update interval.






49. An IOS feature in which multiple routing tables and routing forwarding instances exist in a single router - with interfaces being assigned to one of the several VRFs. This feature allows separating of routing domains inside a single router platform.






50. In the context of SNMP - the Response command is sent by an SNMP agent - back to a manager - in response to any of the three types of Get requests - or in response to a Set request. It is also used by a manager in response to a received Inform comman
