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 NTP mode in which an NTP host adjusts its clock in relation to an NTP server's clock.






2. An SPF calculation as a result of changes inside the same area as a router - for which the SPF run must examine the full LSDB.






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






4. A term referring to the process of applying the Message Digest 5 (MD5) algorithm to a string - resulting in another value. The original string cannot be easily computed even when the hash is known - making this process a strong method for storing pas






5. 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






6. A set of rules by which BGP examines the details of multiple BGP routes for the same NLRI and chooses the single best BGP route to install in the local BGP table.






7. An 802.1d STP transitory port state in which the port does not send or receive frames - but does learn the source MAC addresses from incoming frames.






8. The original standardized set of generic SNMP MIB variables - defined in RFC 1158.






9. Used to reserve network resources for a flow as it traverses the network. A device that creates an RSVP reservation guarantees that it can provide the bandwidth - latency - or other resources that are requested by RSVP.






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






11. The process by which neighboring OSPF routers examine their Hello messages and elect the DR. The decision is based on priority (highest) - or RID (highest) if priority is a tie.






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






13. The data structure used by OSPF to hold LSAs.






14. An alternative software loaded into a Cisco router - used for low-level debugging and for password recovery.






15. Router Advertisement.






16. Sent by a PIM router - by default every 30 seconds - on every interface on which PIM is configured to discover neighbors - establish adjacency - and maintain adjacency.






17. The RFC-standard MPLS protocol used to advertise the binding (mapping) information about each particular IP prefix and associated label. See also TDP.






18. In MQC and CB Policing - a configuration style by which - for one category of packets (conform - exceed - or violate) - more than one marking action is defined for a single category. For example - marking DSCP and DE.






19. A workstation or server configured to collect and present RMON data for reporting purposes.






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






21. Not-so-stubby area.






22. 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.






23. 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






24. A Cisco IOS queuing tool that uses MQC configuration commands - reserves a minimum bandwidth for some queues - provides high-priority scheduling for some queues - and polices those queues to prevent starvation of lower-priority queues during interfac






25. In BGP - either external BGP (eBGP) - confederation eBGP - or internal BGP (iBGP). The term refers to a peer connection - and whether the peers are in different ASs (eBGP) - different confederation sub-ASs (confederation eBGP) - or in the same AS (iB






26. In the PIM-SM design - the process by which a source DR - after it starts to receive the group traffic - encapsulates the multicast packets in the unicast packets and sends them to the RP.






27. The process - defined by FRF.5 and FRF.8 - for combining ATM and FR technologies for an individual VC.






28. A type of IPv4 and IPv6 traffic designed primarily to provide one-to-many connectivity but unlike broadcast - has the capability to control the scope of traffic distribution.






29. Data terminal equipment.






30. From one multicast router's perspective - the upstream router is another router that has just forwarded a multicast packet to that router.






31. Receivers subscribe to an (S -G) channel when they request to join a multicast group. That is - they specify the unicast IP address of their multicast source and the group multicast address. SSM is typically used in very large multicast deployments s






32. 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






33. Ethernet process by which devices attached to the same cable negotiate their speed and the duplex settings over the cable.






34. Time Interval.






35. Another term for summary route.






36. Aka network layer reachability information.






37. With routing protocols - the process by which the router receiving a routing update determines if the routing update came from a trusted router.






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






39. The speed at which the access link is clocked. This choice affects the price of the connection and many aspects of traffic shaping and policing - compression - quality of service - and other configuration options.






40. 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.






41. Sequence number.






42. Neighbor Discovery Protocol.






43. An early T1 framing standard.






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






45. With RIP - a per-route timer (default 180 seconds) that begins when a route's metric changes to a larger value.






46. Frame Relay Forum.






47. 16 bits between the interface ID and global routing prefix in an IPv6 global address - used for subnet assignment inside an enterprise.






48. In the context of SNMP - the GetBulk command is sent by an SNMP manager - to an agent - requesting the values of multiple variables. The GetBulk command allows retrieval of complex structures - like a routing table - with a single command - as well a






49. Cell Loss Priority.






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