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. The process of breaking a frame into pieces - sending some of the fragments - and then sending all or part of a different packet - all of which is done to reduce the delay of the second packet.






2. A process on a computing device that issues requests for SNMP MIB variables from SNMP agents - receives and processes the MIB data - and accepts unsolicited Trap messages from SNMP agents.






3. Link-State Refresh. A timer that determines how often the originating router should reflood an LSA - even if no changes have occurred to the LSA.






4. Protocol Independent Multicast dense-mode routing protocol.






5. A NAT term describing an IP address representing a host that resides outside the enterprise network - with the address being used in packets inside the enterprise network.






6. 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






7. The command used to initialize a SPAN or RSPAN session on a Catalyst switch.






8. A Cisco-proprietary feature by which multiple routers can provide interface IP address redundancy - as well as cause a set of clients to load-balance their traffic across multiple routers inside the GLBP group.






9. 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.






10. Label Forwarding Information Base.






11. The second most significant bit in the most significant byte of an Ethernet MAC address - a value of binary 0 implies that the address is a Universally Administered Address (UAA) (also known as Burned-In Address [BIA]) - and a value of binary 1 impli






12. 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.






13. An Internet standard authentication protocol that uses secure hashes and a three-way handshake to perform authentication over a PPP link.






14. Boot Protocol. A standard (RFC 951) protocol by which a LAN-attached host can dynamically broadcast a request for a server to assign it an IP address - along with other configuration settings - including a subnet mask and default gateway IP address.






15. A prestandard (at the time of publication) wireless LAN physical layer that offers data rates in the hundreds of megabits per second.






16. The first 48 bits of an IPv6 global address - used for efficient route aggregation.






17. The speed at which the access link is clocked. This choice affects the price of the connection and many aspects of traffic shaping and policing - compression - quality of service - and other configuration options.






18. The password required by the enable command. Also - this term may specifically refer to the password defined by the enable password command.






19. The router in a VRRP group that is currently actively forwarding IP packets. Conceptually the same as an HSRP Active router.






20. The definitions for a particular set of data variables - with those definitions following the SMI specifications. See also SMI.






21. Point-to-Point Protocol over Ethernet. A convention often used as the data link protocol over Cable in which Ethernet is used as the data link protocol - but with PPP being encapsulated inside Ethernet. The combination gives the data link features of






22. Software-based collection and reporting tool for data reported by NetFlow.






23. Enhances RP redundancy by providing a method for RPs to exchange multicast source information - even between multicast domains.






24. A WRED process by which WRED discards all newly arriving packets intended for a queue - based on whether the queue's maximum threshold has been exceeded.






25. Maximum Response Time.






26. A Cisco IOS configuration tool that can be used to match routing updates based on a base network address - a prefix - and a range of possible masks used inside the values defined by the base network address and prefix.






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






28. An IPv6/IPv4 tunneling method that allows isolated IPv6 domains to be connected over an IPv4 network.






29. Maximum transmission unit.






30. Copper cable with RJ-45 connectors in which a twisted pair at pins 1 -2 on the first end of the cable is connected to pins 3 -6 on the other end - with a second pair connected to pins 3 -6 on the first end and pins 1 -2 on the other end.






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






32. 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






33. 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.






34. A basic form of traffic shaping that is applied to an interface or subinterface. By default - it shapes all traffic leaving the interface - but can be modified by using an access control list. The access list controls only what traffic is shaped; GTS






35. A packet-scheduling algorithm used in Cisco switches that provides similar behavior to CBWFQ in shared mode and polices in shaped mode.






36. An optimized Layer 3 forwarding path through a router or switch. CEF optimizes routing table lookup by creating a special - easily searched tree structure based on the contents of the IP routing table. The forwarding information is called the Forward






37. Link-state database.






38. 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






39. A Frame Relay traffic shaping feature during which the shaping rate is reduced when the shaper notices congestion through the receipt of BECN or ForeSight messages.






40. Forwarding Equivalence Class.






41. Weighted round-robin.






42. One-time password.






43. A process on a computing device that accepts SNMP requests - responds with SNMP-structured MIB data - and initiates unsolicited Trap messages back to an SNMP management station.






44. A field in the IP header that is decremented at each pass through a Layer 3 forwarding device.






45. An E-LSR in an MPLS VPN network whose role in a particular discussion is to receive unlabeled packets over customer links and then forward the packets as labeled packets into the MPLS network.






46. A queuing scheduler concept - much like CQ's scheduler - in which queues are given some service in sequence. This term is often used with queuing in Cisco LAN switches.






47. Data terminal equipment.






48. Virtual Routing and Forwarding table.






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. Password Authentication Protocol.
