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 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.






2. A well-known discretionary BGP path attribute that flags a route as being a summary route.






3. A router that should either permanently or temporarily not be used as a transit router. Can wait a certain time after OSPF process start - or after BGP notifies OSPF that BGP has converged - before ceasing to be a stub router.






4. A subset of a classful IP network - as defined by a subnet mask - which used to address IP hosts on the same Layer 2 network in much the same way as a classful network is used.






5. Any other router - sharing a common data link - with which a router exchanges Hellos - and for which the parameters in the Hello pass the parameter-check process.






6. Link Access Procedure for Frame-Mode Bearer Services.






7. A method for optimizing the flow of multicast IP packets passing through a LAN switch. The switch using IGMP snooping examines IGMP messages to determine which ports need to receive traffic for each multicast group.






8. An enhanced version of WEP that is part of the 802.11i standard and has an automatic key-update mechanism that makes it much more secure than WEP. TKIP is not as strong as AES in terms of data protection.






9. A switch feature in which the switch examines DHCP messages and - for untrusted ports - filters all messages typically sent by servers and inappropriate messages sent by clients. It also builds a DHCP snooping binding table that is used by DAI and IP






10. A message sent by each host - either in response to a router Query or on its own - to all multicast groups for which it would like to receive multicast traffic.






11. 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.






12. WRED compares this setting to the average queue depth to decide whether packets should be discarded. No packets are discarded if the average queue depth falls below this minimum threshold.






13. A bit in the LAPF Frame Relay header that - when set to 1 - implies that the frame has experienced congestion.






14. An FRF standard for Frame Relay-to-ATM Service Interworking in which both DTEs use Frame Relay - with ATM in between.






15. 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






16. Frame Relay Forum.






17. On a serial cable - the pin lead set by the DTE to tell the DCE that the DTE wants to send data.






18. When a Query is received from a router - each host randomly picks a time between 0 and the Maximum Response Time period to send a Report. When the host with the smallest time period first sends the Report - the rest of the hosts suppress their report






19. A term used with Cisco LAN switches - referring to a queue treated with strict-priority scheduling.






20. With OSPF - the encapsulation of OSPF messages inside IP - to a router with which no common subnet is shared - for the purpose of either mending partitioned areas or providing a connection from some remote area to the backbone area.






21. 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.






22. Link-State Update.






23. Expedited Forwarding.






24. A bit inside the Frame Relay header that - when set - implies that congestion occurred in the direction opposite (or backward) as compared with the direction of the frame.






25. The mandatory contention-based 802.11 access protocol that is also referred to as CSMA/CA.






26. The combination of MPLS labels and links over which a packet will be forwarded over an MPLS network - from the point of ingress to the MPLS network to the point of egress.






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






28. Sent by a PIM router to its upstream router to either request that the upstream router forward the group traffic or stop forwarding the group traffic that is currently being forwarded. If a PIM router wants to start receiving the group traffic - it l






29. An FRF standard for Frame Relay-to-ATM Service Interworking in which one DTE uses Frame Relay and one uses ATM.






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






31. A set of all devices for which any frame sent by one of the devices would collide with any frames transmitted at the same time by any of the other devices in the set.






32. Switched virtual circuit.






33. In IP routing - a term referring to the process of forwarding packets through a router.






34. Maximum transmission unit.






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. A possible side effect of a scheduler that performs strict-priority scheduling of a queue - which can result in lower-priority queues getting little or no service.






37. Voice over Frame Relay.






38. A neighbor state that signifies the other router has reached neighbor status - having passed the parameter check. The FIB entry details the information needed for forwarding: the next-hop router and the outgoing interface - in an optimized mtrie stru






39. Weighted round-robin.






40. A Cisco IOS configuration tool for routing protocols by which routing updates may be filtered.






41. With OSPF - the OSPF router that wins an election amongst all current neighbors. The DR is responsible for flooding on the subnet - and for creating and flooding the type 2 LSA for the subnet.






42. High Density Binary 3.






43. 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






44. 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.






45. In OSPF - a number assigned to each LSA - ranging from 0x80000001 and wrapping back around to 0x7FFFFFFF - which is used to determine which LSA is most recent.






46. The actual number of packets in a queue at a particular time.






47. Alarm Indication Signal. With T1s - the practice of sending all binary 1s on the line in reaction to problems - to provide signal transitions and allow recovery of synchronization and framing.






48. Protocol Independent Multicast sparse-mode routing protocol.






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






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