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. Backup designated router.






2. The original standardized set of generic SNMP MIB variables - defined in RFC 1158.






3. An OSPF timer that determines how long an LSA can remain in the LSDB without having heard a reflooded copy of the LSA.






4. Defined in RFCs 1517-1520 - a scheme to help reduce Internet routing table sizes by administratively allocating large blocks of consecutive classful IP network numbers to ISPs for use in different global geographies. CIDR results in large blocks of n






5. A process used in routers that are encrypting traffic to permit egress QoS actions to be taken on traffic that is being encrypted on that router. QoS pre-classification keeps a copy of each packet to be encrypted in memory long enough to take the app






6. A Cisco-proprietary messaging protocol implemented in WAN switches that can be used to signal network status - including congestion - independent of end-user frames and cells.






7. Designed to solve the problems of multicast duplication and multicast routing loops. For every multicast packet received - a multicast router examines its source IP address - consults its unicast routing table - determines which interface it would us






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






9. Dynamic Multipoint VPN.






10. A Cisco IOS interface setting - as a percentage between 1 and 99 - that defines how much of the interface's bandwidth setting may be allocated by a queuing tool. The default value is 75 percent.






11. Bootstrap Router.






12. Web Cache Communication Protocol.






13. A T1 alarm state that occurs when a device has detected a local LOF/LOS/AIS condition. The device in Red alarm state then sends a Yellow alarm signal.






14. A characterization of a BGP path attribute in which all BGP implementations must support and understand the attribute (well known) - but BGP Updates can either include the attribute or not depending on whether a related feature has been configured (d






15. A strategy for subnetting a classful network for which all masks/prefixes are the same value for all subnets of that one classful network.






16. Layer 2 payload compression.






17. Provides dynamic inspection of traffic as it traverses the router. It uses Context-Based Access Control (CBAC) to look deeper into a packet than an access list can. It tracks outbound traffic and dynamically allows in responses to that traffic.






18. A BGP path attribute that is communicated throughout a single AS to signify which route of multiple possible routes is the best route to be taken when leaving that AS. A larger value is considered to be better.






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






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






21. A BGP feature by which a router learns iBGP routes - and then forwards them to other iBGP peers - reducing the required number of iBGP peers while also avoiding routing loops.






22. 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.






23. An intrusion detection system that safeguards the wireless LAN from malicious and unauthorized access.






24. On a serial cable - the pin lead set by the DTE to imply that the DTE is ready to signal using pin leads.






25. 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.






26. Cisco Wireless LAN Solution Engine.






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






28. An MPLS VPN term referring to a router at a customer site that does not implement MPLS.






29. Time Interval.






30. An FRF standard for LFI for data (FRF.3) VCs.






31. Controls access to the Internet in public wireless LANs.






32. Superframe






33. Data Set Ready.






34. Protocol Independent Multicast dense-mode routing protocol.






35. Another term for summary route.






36. An MPLS VPN term referring to the more efficient choice of popping the outer label at the second-to-last (penultimate) LSR - which then prevents the egress PE from having to perform two LFIB lookups to forward the packet.






37. A 3-tuple consisting of an IP address - port number - and transport layer protocol. TCP connections exist between a pair of sockets.






38. 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.






39. A WRED process by which WRED does not discard packets during times in which a queue's minimum threshold has not been passed.






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






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. Temporal Key Integrity Protocol.






43. The first 6 bits of the DS field - used for QoS marking.






44. In the context of SNMP - the Get command is sent by an SNMP manager - to an agent - requesting the value of a single MIB variable identified in the request. The Get request identifies the exact variable whose value the manager wants to retrieve. Intr






45. A vendor consortium that formerly worked to further Frame Relay common vendor standards.






46. In IPv6 - the Neighbor Discovery message used by an IPv6 node to send information about itself to its neighbors.






47. Feasible distance.






48. The initial 802.11 common key encryption mechanism; vulnerable to hackers.






49. On a multiaccess network - when a PIM-DM or PIM-SM router receives a Prune message - it starts a 3-second timer. If it receives a Join message on the multiaccess network from another router before the timer expires - it considers the message as an ov






50. A local Cisco-proprietary BGP setting that is not advertised to any peers. A larger value is considered to be better.
