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 standard (RFC 951) protocol by which a LAN-attached host can dynamically broadcast a request for a server to assign it an IP address - along with other configuration settings - including a subnet mask and default gateway IP address.






2. Class-Based Weighted Fair Queuing.






3. A neighbor state that signifies the other router has reached neighbor status - having passed the parameter check. The FIB entry details the information needed for forwarding: the next-hop router and the outgoing interface - in an optimized mtrie stru






4. The number of bytes in a queue that are removed per cycle in MDRR. Similar to byte count in the custom queuing (CQ) scheduler.






5. An FRF standard for LFI for VoFR (FRF.11) VCs - in which all voice frames are interleaved in front of data frames' fragments.






6. The portion of PPP focused on features that are unrelated to any specific Layer 3 protocol.






7. Policing in which a single rate is metered - and packets are placed into one of three categories (conform - exceed - or violate).






8. An exterior routing protocol designed to exchange prefix information between different autonomous systems. The information includes a rich set of characteristics called path attributes - which in turn allows for great flexibility regarding routing ch






9. 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






10. A multicast routing protocol that operates in dense mode and depends on the OSPF unicast routing protocol to perform its multicast functions.






11. Bipolar 8 Zero Substitution. A serial-line encoding standard that substitutes Bipolar Violations in a string of eight binary 0s to provide enough signal transitions to maintain synchronization.






12. A standard (RFC 3768) feature by which multiple routers can provide interface IP address redundancy so that hosts using the shared - virtual IP address as their default gateway can still reach the rest of a network even if one or more routers fail.






13. The specific frequency subband on which the radio card or access point is operating. The RF channel is set in the access point or ad hoc stations.






14. An Internet standard serial data-link protocol - used on synchronous and asynchronous links - that provides data-link framing - link negotiation - Layer 3 interface features - and other functions.






15. Differentiated Services.






16. An IPv6/IPv4 tunneling method that is designed for transporting IPv6 packets within a site where a native IPv6 infrastructures is not available.






17. 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






18. The portions of PPP focused on features that are related to specific Layer 3 protocols.






19. A 3-bit field in an 802.1Q header used for marking frames.






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






21. With EIGRP - the metric (distance) of a route as reported by a neighboring router.






22. A routing protocol feature by which the routing update includes the entire set of routes - even if some or all of the routes are unchanged.






23. An intrusion detection system that safeguards the wireless LAN from malicious and unauthorized access.






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






25. On a multiaccess network - when a PIM-DM or PIM-SM router receives a Prune message - it starts a 3-second timer. If it receives a Join message on the multiaccess network from another router before the timer expires - it considers the message as an ov






26. A wireless LAN physical layer that is backward compatible with 802.11b and operates at up to 54-Mbps data rates using OFDM in the 2.4-GHz band.






27. An early standard from AT&T for encoding analog voice as a digital signal for transmission over a TDM network. PCM requires 64 kbps - and is the basis for the DS0 speed.






28. Message sent by a PIM-DM router to a downstream router when it receives a Graft message from the downstream router; sent using the unicast address of the downstream router.






29. Weighted round-robin.






30. A method for optimizing the flow of multicast IP packets passing through a LAN switch. The switch using IGMP snooping examines IGMP messages to determine which ports need to receive traffic for each multicast group.






31. Layer 2 payload compression.






32. WRED compares this setting to the average queue depth to decide whether packets should be discarded. No packets are discarded if the average queue depth falls below this minimum threshold.






33. On a serial cable - the pin lead set by the DCE to tell the DTE that the DTE is allowed send data.






34. The operating mode of shaped round-robin that provides a low-latency queue with policing.






35. A term generally describing characteristics about BGP paths that are advertised in BGP Updates.






36. PIM-SM is a method of routing multicast packets that requires some intelligence in the network about the locations of receivers so that multicast traffic is not flooded into areas with no receivers. PIM Sparse Mode gets its name from the assumption t






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






38. Maximum Response Time.






39. A queuing scheduler's logic by which - if a particular queue has packets in it - those packets always get serviced next.






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






41. In IPv6 - a Router Advertisement message used by an IPv6 router to send information about itself to nodes and other routers connected to that router.






42. A local Cisco-proprietary BGP setting that is not advertised to any peers. A larger value is considered to be better.






43. Jargon used by STP mostly when discussing the root election process; refers to a Hello with a lower bridge ID. Sometimes refers to a Hello with the same bridge ID as another - but with better values for the tiebreakers in the election process.






44. An IOS feature in which multiple routing tables and routing forwarding instances exist in a single router - with interfaces being assigned to one of the several VRFs. This feature allows separating of routing domains inside a single router platform.






45. 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.






46. 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.






47. Router Advertisement.






48. The common set of IOS configuration commands that is used with each QoS feature whose name begins with "Class-Based."






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






50. An SPF calculation for which a router does not need to run SPF for any LSAs inside its area - but instead runs a very simple algorithm for changes to LSAs outside its own area.
