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. Ethernet feature in which a NIC or Ethernet port can both transmit and receive at the same instant in time. It can be used only when there is no possibility of collisions. Loopback circuitry on NIC cards is disabled to use full duplex.






2. In SNMP - the process of a manager using successive GetNext and GetBulk commands to discover the exact MIB structure supported by an SNMP agent. The process involves the manager asking for each successive MIB leaf variable.






3. Discard Eligible.






4. A Cisco IOS configuration tool for RIP and EIGRP for which the list matches routes in routing updates - and adds a defined value to the sent or received metric for the routes. The value added to the metric is the offset.






5. 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.






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






7. The IEEE standardized protocol for VLAN trunking.






8. A time value that each wireless station must set based on the duration value found in every 802.11 frame. The time value counts down and must be equal to zero before a station is allowed to access the wireless medium. The result is a collision-avoida






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






10. 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.






11. A Cisco 12000 series router feature that combines the key features of LLQ and CQ to provide similar congestion-management features.






12. On a serial cable - the pin lead set by the DCE to imply a working link.






13. 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






14. 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.






15. 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.






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






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. A Cisco IOS queuing tool that uses MQC configuration commands - reserves a minimum bandwidth for some queues - provides high-priority scheduling for some queues - and polices those queues to prevent starvation of lower-priority queues during interfac






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






20. Inverse ARP.






21. Gateway Load Balancing Protocol.






22. Differentiated Services Code Point.






23. With EIGRP - the metric (distance) of a route as reported by a neighboring router.






24. A type of logic for how a router uses a default route. When a default route exists - and the class A - B - or C network for the destination IP address does not exist in the routing table - the default route is used. If any part of that classful netwo






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






26. An MPLS term referring to any device that can forward packets that have MPLS labels.






27. A wireless LAN that offers connections to the Internet from public places - such as airports - hotels - and coffee shops.






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






29. The RMON function of sending a notification to an RMON collector or the console. Triggered by an RMON event.






30. 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






31. An FRF standard for payload compression.






32. IP routing The simplest MPLS application - involving the advertisement of an IGP to learn IP routes - and LDP or TDP to advertise labels.






33. Also known as triggered updates.






34. Per-VLAN Spanning Tree Plus.






35. The portion of PPP focused on negotiating IP features






36. Network Address Translation-Protocol Translation.






37. 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.






38. IP Control Protocol.






39. Cisco IOS router feature by which a route map determines how to forward a packet - typically based on information in the packet other than the destination IP address.






40. Weighted random early detection.






41. Custom queuing






42. Multilink PPP.






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






44. Mark probability denominator.






45. A routing protocol feature by which the routing update includes only routes that have changed - rather than include the entire set of routes.






46. An Internet standard (RFC 1305) that defines the messages and modes used for IP hosts to synchronize their time-of-day clocks.






47. Used to reserve network resources for a flow as it traverses the network. A device that creates an RSVP reservation guarantees that it can provide the bandwidth - latency - or other resources that are requested by RSVP.






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






49. A type of spread spectrum that spreads RF signals over the frequency spectrum by transmitting the signal at different frequencies according to a hopping pattern. One of the original 802.11 physical layers used FHSS to offer data rates of 1 and 2 Mbps






50. Alternate Mark Inversion. A serial-line encoding standard that sends alternating positive and negative 3-volt signals for binary 1 - and no signal (0 V) for binary 0.
