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. A BGP router in an AS that uses route reflectors - but that is not aided by any RR server.






2. With PIM on a multiaccess network - the PIM router with the highest IP address on the subnet. It is also the IGMPv1 Querier. The DR is responsible for the following tasks: - Sending PIM register and PIM join and prune messages toward the RP to infor






3. 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.






4. With RIP - a per-route timer - which is reset and grows with the Invalid timer. When the Flush timer mark is reached (default 240 seconds) - the router removes the route from the routing table - and now accepts any other routes about the failed subne






5. Area Border Router. An OSPF router that connects to the backbone area and to one or more non-backbone areas.






6. With EIGRP - for a particular route - the case in which the RD is lower than the FD.






7. In MPLS VPNs - an entity in a single router that provides a means to separate routes in different VPNs. The VRF includes per-VRF instances of routing protocols - a routing table - and an associated CEF FIB.






8. A Cisco IOS queuing tool most notable for its automatic classification of packets into separate per-flow queues.






9. 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






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






11. 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






12. A route that is used for forwarding packets when the packet does not match any more specific routes in the IP routing table.






13. In 802.1X - the computer that stores usernames/passwords and verifies that the correct values were submitted before authenticating the user.






14. 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






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






16. A Frame Relay address used in Frame Relay headers to identify the VC






17. Copper cable with RJ-45 connectors in which the wire at pin 1 on one end is connected to pin 1 on the other end; the wire at pin 2 is connected to pin 2 on the other end; and so on.






18. Authentication - authorization - and accounting.






19. Permanent virtual circuit.






20. Orthogonal frequency division multiplexing.






21. 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






22. A BGP message that includes withdrawn routes - path attributes - and NLRI.






23. Data communications equipment.






24. An IPv6 migration strategy in which a host or router supports both IPv4 and IPv6 natively.






25. The structure inside telcos' original digital circuit build-out in the mid-1900s - based upon using TDM to combine and disperse smaller DS levels into larger levels - and vice versa.






26. Class of Service.






27. A Cisco IOS queuing tool most notable for its scheduler - which always services the high-priority queue over all other queues.






28. With some routing protocols - the time period between successive Hello messages.






29. Data Set Ready.






30. A message sent by each host - either in response to a router Query or on its own - to all multicast groups for which it would like to receive multicast traffic.






31. A Cisco IOS configuration tool for routing protocols by which routing updates may be filtered.






32. Distance Vector Multicast Routing Protocol.






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






34. Voice over Frame Relay.






35. A set of packets in an MPLS network for which the MPLS network will apply the exact same forwarding behavior.






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






37. Secure Shell protocol used for character-oriented command-line access and configuration. A highly secure alternative to Telnet.






38. A Layer 3 forwarding path through a router that does not optimize the forwarding path through the router.






39. 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.






40. DCE devices are one of two devices on either end of a communications circuit - specifically the device with more control over the communications. Frame Relay switches are DCE devices. DCEs are also known as data circuit-terminating equipment (DTE).






41. 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






42. An issue whereby parts of the RF signal take different paths from the source to the destination - which causes direct and reflected signals to reach the receiver at different times - and corresponding bit errors.






43. A possible side effect of a scheduler that performs strict-priority scheduling of a queue - which can result in lower-priority queues getting little or no service.






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






45. Structure of Management Information.






46. 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.






47. An integer setting for EIGRP and IGRP. Any FS route whose metric is less than this variance multiplier times the successor's metric is added to the routing table - within the restrictions of the maximum-paths command.






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






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






50. 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.
