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. An 802.1w RSTP port state in which the port is not the Root Port but is available to become the root port if the current root port goes down.






2. A wireless LAN that offers connections to the Internet from public places - such as airports - hotels - and coffee shops.






3. An Internet standard authentication protocol that uses clear-text passwords and a two-way handshake to perform authentication over a PPP link.






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






5. Finish time.






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






7. 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.






8. A type of logic for how a router uses a default route. When a default route exists - and no more specific match is made between the destination of the packet and the routing table - the default route is used.






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






10. High Density Binary 3.






11. A BGP path attribute that allows routers in one AS to set a value and advertise it into a neighboring AS - impacting the decision process in that neighboring AS. A smaller value is considered better. Also called the BGP metric.






12. 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.






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






14. Aka network layer reachability information.






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. A technology that sends a high-speed data stream over multiple subcarriers simultaneously. It is highly immune to multipath interference. 802.11a and 802.11g specify the use of OFDM.






17. A type of routing protocol convergence event in which the metric for a route increases slightly over time because of the advertisement of an invalid route.






18. Virtual Routing and Forwarding table.






19. An architecture and set of documents that defines Cisco's best recommendations for how to secure a network.






20. Network Layer Protocol ID is a field in the RFC 2427 header that is used as a Protocol Type field in order to identify the type of Layer 3 packet encapsulated inside a Frame Relay frame.






21. An E-LSR in an MPLS VPN network whose role in a particular discussion is to receive labeled packets from other LSRs and then forward the packets as unlabeled packets to CE routers.






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






23. Data Set Ready.






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






25. A reserved value for the BGP COMMUNITY path attribute that implies that the route should not be advertised to any other peer.






26. Network Address Translation.






27. A single instance of STP that is applied to multiple VLANs - typically when using the 802.1Q trunking standard.






28. 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.






29. With a routing update - or routing table entry - the portion of a route that defines the next router to which a packet should be sent to reach the destination subnet. With routing protocols - the Next Hop field may define a router other than the rout






30. On a serial cable - the pin lead set by the DCE to imply a working link.






31. The single port on each nonroot switch upon which the best Hello BPDU is received.






32. A number between 1 and 64 -511 (public) and 64 -512 and 65 -535 (private) assigned to an AS for the purpose of identifying a specific BGP domain.






33. A term used with Cisco LAN switches - referring to a queue treated with strict-priority scheduling.






34. In the context of SNMP - the Inform command is sent by an SNMP manager to communicate a set of variables - and their values - to another SNMP manager. The main purpose is to allow multiple managers to exchange MIB information - and work together - wi






35. An OSPF router that connects to the backbone area and to one or more non-backbone area.






36. Cisco Express Forwarding.






37. A set of four hex digits listed in an IPv6 address. Each quartet is separated by a colon.






38. An interface on a Cisco IOS-based switch that is treated as if it were an interface on a router.






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






40. An MPLS term referring to the first of several labels when an MPLS-forwarded packet has multiple labels (a label stack).






41. Tag Distribution Protocol.






42. With private VLANs - a port that can send and receive frames with all other ports in the private VLAN.






43. 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.






44. A method used by an IPv6 host to determine its own IP address - without DHCPv6 - by using NDP and the modified EUI-64 address format. See also stateful autoconfiguration.






45. Protocol data unit.






46. 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






47. Local Management Interface.






48. With routing protocols - the measurement of favorability that determines which entry will be installed in a routing table if more than one router is advertising that exact network and mask.






49. An attack by which the attacker initiates many TCP connections to a server - but does not complete the TCP connections - by simply not sending the third segment normally used to establish the connection. The server may consume resources and reject ne






50. A state variable kept by a router for each known neighbor or potential neighbor.
