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. In Frame Relay - a link between a router and a Frame Relay switch.






2. PIM-DM is a method of routing multicast packets that depends on a flood-and-prune approach. PIM Dense Mode gets its name from the assumption that there are many receivers of a particular multicast group - close together (from a network perspective).






3. Dynamic Host Configuration Protocol.






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






5. 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.






6. 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.






7. The range 233.0.0.0 through 233.255.255.255 that IANA has reserved (RFC 2770) on an experimental basis. It can be used by anyone who owns a registered autonomous system number to create 256 global multicast addresses.






8. Internal BGP.






9. An NTP mode in which an NTP host adjusts its clock in relation to an NTP server's clock.






10. 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






11. Out of Frame.






12. Multicast Open Shortest Path First.






13. An FRTS configuration construct - configured with the map-class frame-relay global configuration command.






14. Part of the Cisco IOS Firewall feature set - CBAC inspects traffic using information in the higher-layer protocols being carried to decide whether to open the firewall to specific inbound traffic. CBAC supports both UDP and TCP and multiple higher-la






15. A wireless LAN physical layer that operates at up to 54-Mbps data rates using OFDM in the 5-GHz band.






16. Request-to-send/clear-to-send.






17. 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.






18. 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






19. Jargon referring to the minimum value to which adaptive shaping will lower the shaping rate.






20. IP routing The simplest MPLS application - involving the advertisement of an IGP to learn IP routes - and LDP or TDP to advertise labels.






21. A reserved value for the BGP COMMUNITY path attribute that implies that the route should not be advertised outside the local AS.






22. With EIGRP - a route that is not a successor route - but that meets the feasibility condition; can be used when the successor route fails - without causing loops.






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






24. Data Carrier Detect.






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






26. Database Description.






27. One of the two modes of MDRR - in which the priority queue is serviced between each servicing of the non-priority queues.






28. Multiple Spanning Trees.






29. A Cisco-proprietary feature. After a Cisco multicast router receives IGMP Join or Leave messages from hosts - it communicates to the connected Cisco switches - telling them which hosts (based on their unicast MAC addresses) have joined or left each m






30. An individual line in an ACL.






31. Defined in RFC 1631 - a method of translating IP addresses in headers with the goal of allowing multiple hosts to share single public IP addresses - thereby reducing IPv4 public address depletion.






32. 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






33. Ready To Send.






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






35. Cisco IOS router feature by which a route map determines how to forward a packet - typically based on information in the packet other than the destination IP address.






36. The underlying algorithms associated with RIP.






37. 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.






38. Network Address Translation.






39. A type of OSPF packet used to acknowledge LSU packets.






40. AutoQoS is a macro that creates and applies quality of service configurations based on Cisco best-practice recommendations.






41. Weighted round-robin.






42. 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






43. A wireless LAN that includes the use of access points. Infrastructure mode connects wireless users to a wired network and allows wireless users to roam throughout a facility between different access points. All 802.11 data frames in an infrastructure






44. An MPLS term describing designs in which one or more MPLS customer sites can be reached from multiple other VPNs.






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






46. A Cisco-proprietary STP implementation - created many years before IEEE 802.1s and 802.1w - that speeds convergence and allows for one STP instance for each VLAN.






47. A style of attack in which an ICMP Echo is sent with a directed broadcast (subnet broadcast) destination IP address - and a source address of the host that is being attacked. The attack can result in the Echo reaching a large number of hosts - all of






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






49. Committed information rate.






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