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 802.1d STP port state in which the port does not send or receive frames - except for listening for received Hello BPDUs.






2. An EIGRP message that informs neighbors about routing information. Update messages require an Ack.






3. Direct sequence spread spectrum.






4. A method of collecting traffic received on a switch port or a VLAN and sending it to specific destination ports on a switch other than the one on which it was received.






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. A term referring to the MQC service-policy command - which is used to enable a policy map on an interface.






7. Inverse ARP.






8. 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.






9. Not-so-stubby area.






10. A type of OSPF stub 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 cannot be injected into a totally stubby area.






11. Port Aggregation Protocol.






12. 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.






13. A type of AS_PATH segment consisting of an unordered list of ASNs consolidated from component subnets of a summary BGP route.






14. Backup designated router.






15. An MPLS VPN term referring to an LSR that has no direct customer connections - meaning that the P router does not need any visibility into the VPN customer's IP address space.






16. Version 6 of the IP protocol - which uses 128-bit IP addresses.






17. When a wireless station connects to an access point - the access point assigns an association ID (AID) to the station. Various protocols - such as power-save mode - make use of the association ID.






18. 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






19. Database Description.






20. Controls the distribution of multicast traffic for the private multicast address range 239.0.0.0 to 239.255.255.255 by configuring a filter and applying it on the interfaces.






21. On a serial cable - the pin lead set by the DTE to tell the DCE that the DTE wants to send data.






22. The multicast IP address 224.0.0.6 - listened for by DR and BDR routers.






23. Peak information rate.






24. Receiver's advertised window.






25. A basic form of traffic shaping that is applied to an interface or subinterface. By default - it shapes all traffic leaving the interface - but can be modified by using an access control list. The access list controls only what traffic is shaped; GTS






26. A T1 alarm state that occurs when a device receives a Yellow Alarm signal. This typically means that the device on the other end of the line is in a Red Alarm state.






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






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






29. 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.






30. A term referring to how a router views a BGP peer relationship - in which the peer is in another AS.






31. 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.






32. Area 0; the area to which all other OSPF areas much connect in order for OSPF to work.






33. 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.






34. 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






35. Jargon referring to any queue that receives priority service - often used for queues in an LLQ configuration that have the priority command configured.






36. A protocol - defined in RFC 2865 - that defines how to perform authentication between an authenticator (for example - a router) and an authentication server that holds a list of usernames and passwords.






37. 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.






38. A router feature used when a router sees an ARP request searching for an IP host's MAC - when the router believes the IP host could not be on that LAN because the host is in another subnet. If the router has a route to reach the subnet where the ARP-






39. The process of installing a multicast application; also referred to as launching an application.






40. The router that will receive the group traffic when a multicast router forwards group traffic to another router.






41. Three core security functions.






42. Modified Deficit Round-Robin.






43. Extended Superframe.






44. A type of OSPF packet used to discover neighbors - check for parameter agreement - and monitor the health of another router.






45. An individual line in an ACL.






46. 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






47. A Cisco-proprietary protocol used to dynamically negotiate whether the devices on an Ethernet segment want to form a trunk and - if so - which type (ISL or 802.1Q).






48. Virtual Routing and Forwarding table.






49. A designated router that is directly connected with a source of the multicast group.






50. The IP address to which Label Distribution Protocol (LDP) sends LDP Hellos. Also used in IP multicast to send packets to all multicast routers.
