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 BGP feature that overcomes the requirement of a full mesh of iBGP peers inside a single AS by separating the AS into multiple sub-autonomous systems.






2. Another name for Superframe.






3. Cisco-proprietary STP feature in which a switch port monitors for STP BPDUs of any kind - err-disabling the port upon receipt of any BPDU.






4. Internet Group Management Protocol.






5. Maximum Response Time.






6. 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.






7. The combination of PVST+ and Rapid Spanning Tree. It provides subsecond convergence time and is compatible with PVST+ and MSTP.






8. With OSPF - the timer used to determine when a neighboring router has failed - based on a router not receiving any OSPF messages - including Hellos - in this timer period.






9. With EIGRP - for a particular route - the case in which the RD is lower than the FD.






10. In MPLS VPNs - a 64-bit Extended Community path attribute attached to a BGP route for the purpose of controlling into which VRFs the route is added.






11. Multicast Open Shortest Path First.






12. 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






13. In BGP - either external BGP (eBGP) - confederation eBGP - or internal BGP (iBGP). The term refers to a peer connection - and whether the peers are in different ASs (eBGP) - different confederation sub-ASs (confederation eBGP) - or in the same AS (iB






14. 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.






15. Virtual Router Redundancy Protocol.






16. 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






17. Out of Frame.






18. 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.






19. Digital Signal Level 0.






20. A message sent by a multicast router - by default every 125 seconds - on each of its LAN interfaces to determine whether any host wants to receive multicast traffic for any group.






21. An exterior routing protocol that predates BGP. It is no longer used today.






22. The 32-bit number used to represent an OSPF router.






23. A PPP feature used to load balance multiple parallel links at Layer 2 by fragmenting frames - sending one frame over each of the links in the bundle - and reassembling them at the receiving end of the link.






24. The process of taking the IP and TCP headers of a packet - compressing them - and then uncompressing them on the receiving router.






25. 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.






26. Network Address Translation-Protocol Translation.






27. With PIM on a multiaccess network - the PIM router with the highest IP address on the subnet. It is also the IGMPv1 Querier. The DR is responsible for the following tasks: - Sending PIM register and PIM join and prune messages toward the RP to infor






28. On a serial cable - the pin lead set by the DCE to tell the DTE that the DTE is allowed send data.






29. The IPv6 protocol used for the discovery of which hosts are listening for which multicast IP addresses for IPv6.






30. In BGP - a configuration construct in which multiple neighbors' parameters can be configured as a group - thereby reducing the length of the configuration. Additionally - BGP performs routing policy logic against only one set of Updates for the entir






31. In shaping and policing - the definition of parameters that together imply the allowed rate and bursts.






32. A method of Link Fragmentation and Interleaving (LFI) over interfaces that natively use Frame Relay encapsulation. The routers first build MLP-style PPP headers - which are then encapsulated inside a Frame Relay header. The PPP headers are then used






33. Inter-Switch Link.






34. An optional contention-free 802.11 access protocol that requires the access point to poll wireless stations before they are able to send frames. Not commonly implemented.






35. Ready To Send.






36. An 802.1d STP port state in which the port does not send or receive frames - except for listening for received Hello BPDUs.






37. Similar to an appliance firewall - in that interfaces are placed into security zones. Traffic is allowed between interfaces in the same zone. You can apply policies to filter and control traffic between zones.






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






39. A term used with WFQ for the number assigned to a packet as it is enqueued into a WFQ. WFQ schedules the currently lowest SN packet next.






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






41. Cisco IOS Embedded Event Manager - a feature that monitors events on a router and reports their results. Principally intended to increase availability - EEM provides flexible - granular detection and alerting functions.






42. An IPv6 migration strategy in which a host or router supports both IPv4 and IPv6 natively.






43. Neighbor Advertisement.






44. Common Spanning Tree.






45. Layer 2 payload compression.






46. Jargon used to refer to the first of two buckets in the dual token bucket model; its size is Bc.






47. A workstation or server configured to collect and present RMON data for reporting purposes.






48. An MPLS term referring to the MPLS label just before the IP header. Also called the VPN label when implementing MPLS VPNs.






49. 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.






50. A feature of Ethernet NICs. When the NIC transmits an electrical signal - it "loops" the transmitted electrical current back onto the receive pair. By doing so - if another NIC transmits a frame at the same time - the NIC can detect the overlapping r
