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. Provider router.






2. Dynamic Host Configuration Protocol.






3. With EIGRP - a purposefully slowly changing measurement of round-trip time between neighbors - from which the EIGRP RTO is calculated.






4. A router that is not an ABR or ASBR in that all of its interfaces connect to only a single OSPF area.






5. 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.






6. The notation in a Cisco IOS IP routing table that identifies the route used by that router as the default route.






7. A WFQ term referring to its drop logic - which is similar to tail-drop behavior.






8. Area Border Router. An OSPF router that connects to the backbone area and to one or more non-backbone areas.






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






10. Aka minimum CIR.






11. A T1 alarm state that occurs when the receiver can no longer consistently identify the frame. See LOF.






12. 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






13. A BGP path attribute that lists the next-hop IP address used to reach an NLRI.






14. Enables a wireless client to securely roam between access points in the same subnet or between subnets with access point handoff times within 50 ms.






15. 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.






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






17. A standard (RFC 2131) protocol by which a host can dynamically broadcast a request for a server to assign to it an IP address - along with other configuration settings - including a subnet mask and default gateway IP address. DHCP provides a great de






18. Policing in which two rates are metered - and packets are placed into one of three categories (conform - exceed - or violate).






19. An FRF standard for payload compression.






20. With EIGRP - a router sharing the same primary subnet - with which Hellos are exchanged - parameters match - and with which routes can be exchanged.






21. A message sent by a host when it wants to leave a group - addressed to the All Multicast Routers address 224.0.0.2.






22. An 802.1d STP transitory port state in which the port does not send or receive frames - but does learn the source MAC addresses from incoming frames.






23. A mapping between each DSCP value and a corresponding CoS value - often used in Cisco LAN switches when performing classification for egress queuing.






24. Out of Frame.






25. Defined in RFC 1293 - this protocol allows a Frame Relay-attached device to react to a received LMI "PVC up" message by announcing its Layer 3 addresses to the device on the other end of the PVC.






26. A term referring generically to ways in which a router or switch can determine whether a particular device or user should be allowed access.






27. Protocol data unit.






28. 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.






29. 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.






30. A component that interfaces with a phone using IP and provides connections to the Public Switched Telephone Network (PSTN).






31. The two computers use a protocol with which to communicate with the same layer on another computer. The protocol defined by each layer uses a header that is transmitted between the computers to communicate what each computer wants to do.






32. A BGP neighbor state in which the BGP neighbors have stabilized and can exchange routing information using BGP Update messages.






33. Message sent by a PIM-DM router to a downstream router when it receives a Graft message from the downstream router; sent using the unicast address of the downstream router.






34. 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.






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






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






37. Auto-Rendezvous Point. Cisco-proprietary protocol that can be used to designate an RP and send RP-Announce messages that advertise its IP address and groups. Also - it can be used to designate a mapping agent that interprets what IP address RP is adv






38. A method of collecting traffic received on a switch port or a VLAN and sending it to specific destination ports on the same switch.






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






40. The range 232.0.0.0 through 232.255.255.255 that is allocated by IANA for SSM destination addresses and is reserved for use by source-specific applications and protocols.






41. Peak information rate.






42. When a PIM-SM router switches from RPT to SPT - it sends a PIM-SM Prune message for the source and the group with the RP bit set to its upstream router on the shared tree. RFC 2362 uses the notation PIM-SM (S - G) RP-bit Prune for this message.






43. Wi-Fi Protected Access. A security standard that includes both TKIP and AES and was ratified by the Wi-Fi Alliance.






44. An SPF calculation as a result of changes inside the same area as a router - for which the SPF run must examine the full LSDB.






45. The All OSPF DR Routers multicast IP address - listened for by DR and BDR routers.






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






47. Uses Modular QoS CLI to control the amount and type of traffic handled by the router or switch control plane. Class maps identify traffic types - and then a service policy applied to the device control plane sets actions for each type of traffic.






48. Backup designated router.






49. A mechanism for conserving battery power in wireless stations. The access point buffers data frames destined to sleeping stations - which wake periodically to learn from information in the beacon frame whether or not data frames are waiting for trans






50. An optional nontransitive BGP path attribute that lists the route reflector cluster IDs through which a route has been advertised - as part of a loop-prevention process similar to the AS_PATH attribute.
