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. Label Forwarding Information Base.






2. A Cisco 12000 series router feature that combines the key features of LLQ and CQ to provide similar congestion-management features.






3. An OSPF area into which external (type 5) LSAs are not introduced by its ABRs; instead - the ABRs originate and inject default routes into the area.






4. Multicast addresses that are not assigned by IANA.






5. In the context of SNMP - the GetNext command is sent by an SNMP manager - to an agent - requesting the value of a single MIB variable. The GetNext request identifies a variable for which the manager wants the variable name and value of the next MIB l






6. Time to Live.






7. A protocol used for reliable multicast and unicast transmissions. Used by EIGRP.






8. When multiple routers are connected to a subnet - only one should be sending IGMP queries. It is called a querier. IGMPv1 does not have any rules for electing a querier. In IGMPv2 and IGMPv3 - a router with the lowest interface IP address on the subn






9. An optimized Layer 3 forwarding path through a router. Fast switching optimizes routing table lookup by creating a special - easily searched table of known flows between hosts.






10. Modified Deficit Round-Robin.






11. The portion of PPP focused on negotiating IP features






12. An EIGRP message that is used to acknowledge reliable EIGRP messages - namely Update - Query - and Reply messages. Acks do not require an Ack.






13. 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






14. A name used for DS1 lines inside the European TDM hierarchy.






15. A characterization of a BGP path attribute in which all BGP implementations must support and understand the attribute (well known) - and all BGP Updates must include the attribute (mandatory).






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






17. Access Control Server. A term referring generically to a server that performs many AAA functions. It also refers to the software product Cisco Secure Access Control Server.






18. A conceptual model used by shapers and policers to represent their internal logic.






19. In OSPF - a router that is prepared to take over the designated router.






20. A wireless LAN that only includes wireless users and no access points. 802.11 data frames in an ad hoc network travel directly between wireless users.






21. Link Control Protocol.






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






23. A TCP variable that defines the largest number of bytes allowed in a TCP segment's Data field. The calculation does not include the TCP header. With a typical IP MTU of 1500 bytes - the resulting default MSS would be 1460. TCP hosts must support an M






24. VLAN Trunking Protocol.






25. Sent by a PIM-DM or PIM-SM router when it receives a multicast packet for a group on a LAN interface that is in the outgoing interface list for the group; includes the administrative distance of the unicast routing protocol used to learn the network






26. A logical concept that represents the path over which frames travel between DTEs. VCs are particularly useful when comparing Frame Relay to leased physical circuits.






27. A term referring to the MQC policy-map command and its related subcommands - which are used to apply QoS actions to classes of packets.






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






29. Used by a policer to classify packets relative to the traffic contract. These packets are considered to be above the traffic contract in all cases.






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






31. The protocol used by content engines to manage traffic flow between routers configured for WCCP and between content engines. WCCP takes advantage of the fact that many web pages (and other content) are regularly accessed by users in a given network.






32. An individual line in an ACL.






33. Another name for 802.1Q-in-Q. See 802.1Q-in-Q.






34. The encapsulation of EAP messages directly inside LAN frames. This encapsulation is used between the supplicant and the authenticator.






35. A 1-byte field in the IP header - originally defined by RFC 791 for QoS marking purposes.






36. The IP address used by hosts as the default gateway in a VRRP configuration. This address is shared by two or more VRRP routers - much as HSRP works.






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






38. The MD5-encoded password defined by the enable secret command.






39. 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.






40. Another term for Port Address Translation. See PAT.






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






42. In IPv6 - an address used in the Neighbor Discovery (ND) process. The format for these addresses is FF02::1:FF00:0000/104 - and each IPv6 host must join the corresponding group for each of its unicast and anycast addresses.






43. 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






44. A Cisco IOS interface software queue queuing strategy implemented automatically when using either form of Frame Relay fragmentation. The system then interleaves packets from the high-priority queue between fragments of the medium-priority queue.






45. 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).






46. An attack similar to a smurf attack - but using packets for the UDP Echo application instead of ICMP.






47. High Density Binary 3.






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






49. Tag Distribution Protocol.






50. 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.
