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. Version 4 of the IP protocol - which is the generally deployed version worldwide (at publication) - and uses 32-bit IP addresses.






2. A BGP path attribute that lists ASNs through which the route has been advertised. The AS_PATH includes four types of segments: AS_SEQ - AS_SET - AS_CONFED_SEQ - and AS_CONFED_SET. Often - this term is used synonymously with AS_SEQ






3. A term used with WFQ for the number assigned to a packet as it is enqueued into a WFQ queue. WFQ schedules the currently lowest FT packet next.






4. The protocol used in IPv6 for many functions - including address autoconfiguration - duplicate address detection - router - neighbor - and prefix discovery - neighbor address resolution - and parameter discovery.






5. A Cisco-proprietary Layer 2 protocol that enables a router to communicate to a switch which multicast group traffic the router does and does not want to receive from the switch.






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






7. The RFC 1997 name for the reserved COMMUNITY path attribute known to Cisco IOS as LOCAL_AS. (See LOCAL_AS.)






8. Reverse ARP.






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






10. Multilayer Switching.






11. An FRF standard for Frame Relay-to-ATM Service Interworking in which one DTE uses Frame Relay and one uses ATM.






12. Instead of advertising all routes out a particular interface - the routing protocol omits the routes whose outgoing interface field matches the interface out which the update would be sent.






13. A Cisco router feature in which the router works to prevent SYN attacks either by monitoring TCP connections flowing through the router - or by actively terminating TCP connection until the TCP connection is established and then knitting the client-s






14. A table inside a router that holds the path attributes and NLRI known by the BGP implementation on that router.






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






16. Used by RRs to denote the RID of the iBGP neighbor that injected the NLRI into the AS.






17. Source-specific multicast.






18. 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.






19. Network Based Application Recognition.






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






21. An optional transitive BGP path attribute used to store 32-bit decimal values. Used for flexible grouping of routes by assigning the group the same COMMUNITY value. Other routers can apply routing policies based on the COMMUNITY value. Used in a larg






22. A component of the IOS IP SLA feature. An IP SLA responder is a router configured to respond to a particular IP SLA message initiated by another router - allowing the routers to work together to provide performance information including UDP jitter an






23. Address Resolution Protocol. Defined in RFC 826 - a protocol used on LANs so that an IP host can discover the MAC address of another device that is using a particular IP address.






24. A type of spread spectrum that spreads RF signals over the frequency spectrum by transmitting the signal at different frequencies according to a hopping pattern. One of the original 802.11 physical layers used FHSS to offer data rates of 1 and 2 Mbps






25. Link Aggregation Control Protocol.






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






27. Reduces the bandwidth necessary for radio management information - such as access point status messages - that is sent across the network by eliminating redundant management information.






28. 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.






29. Each 802.11 station periodically sends a probe request frame on each RF channel and monitors probe response frames that all access points within range send back. Stations use the signal strength of the probe response frames to determine which access






30. A group of devices on one or more LANs that are configured (using management software) so that they can communicate as if they were attached to the same wire - when - in fact - they are located on a number of different LAN segments. Because VLANs are






31. A type of OSPF packet - used to communicate LSAs to another router.






32. Structure of Management Information.






33. Context-Based Access Control.






34. Voice over Frame Relay.






35. In the context of SNMP - the Set command is sent by an SNMP manager - to an agent - requesting that the agent set a single identified variable to the stated value. The main purpose is to allow remote configuration and remote operation - such as shutt






36. With EIGRP - the metric value for the lowest-metric route to a particular subnet.






37. 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.






38. Differentiated Services.






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






40. A BGP router that - unknown to it - is aided by a route reflector server to cause all iBGP routers in an AS to learn all eBGP-learned prefixes.






41. A type of OSPF NSSA area for which neither external (type 5) LSAs are introduced - nor type 3 summary LSAs; instead - the ABRs originate and inject default routes into the area. External routes can be injected into a totally NSSA area.






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






43. A method for how a TCP sender grows its calculated CWND variable - thereby growing the allowed window for the connection. Congestion Avoidance grows CWND linearly.






44. 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.






45. 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






46. An 802.1w RSTP port state in which the port is not forwarding or receiving; covers 802.1d port states disabled - blocking - and listening.






47. An optional transitive BGP path attribute that - for a summary route - lists the BGP RID and ASN of the router that created the summary.






48. A contiguous group of data links that share the same OSPF area number.






49. 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






50. High Density Binary 3.
