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 FRF standard for payload compression.






2. A term used with Cisco LAN switches - referring to a DSCP value used when making QoS decisions about a frame. This value may not be the actual DSCP value in the IP header encapsulated inside the frame.






3. A Cisco IOS feature that provides reporting information to a NetFlow aggregator based on traffic flows.






4. A configuration tool in Cisco IOS that allows basic programming logic to be applied to a set of items. Often used for decisions about what routes to redistribute - and for setting particular characteristics of those routes






5. An exterior routing protocol that predates BGP. It is no longer used today.






6. A 48-bit address that is calculated from a Layer 3 multicast address by using 0x0100.5E as the multicast vendor code (OUI) for the first 24 bits - always binary 0 for the 25th bit - and copying the last 23 bits of the Layer 3 multicast address.






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






8. Any OSPF neighbor for which the database flooding process has completed.






9. IP routing The simplest MPLS application - involving the advertisement of an IGP to learn IP routes - and LDP or TDP to advertise labels.






10. The RMON function of tracking a particular variable. RMON events trigger RMON alarms.






11. Sending a message from a single source or multiple sources to selected multiple destinations across a Layer 3 network in one data stream.






12. In shaping and policing - commonly used to refer to the shaping or policing rate. For WAN services - a common reference to the bit rate defined in the WAN service business contract for each VC.






13. 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






14. A bit inside the Frame Relay header that - when set - implies that congestion occurred in the direction opposite (or backward) as compared with the direction of the frame.






15. Extended Superframe.






16. 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.






17. An FRF standard for LFI for data (FRF.3) VCs.






18. Burst With shaping and policing - the number of additional bits that may be sent after a period of relative inactivity.






19. With DiffServ - a DSCP marking and a related set of QoS actions applied to packets that have that marking.






20. An effort to reduce the query scope with EIGRP - using route summarization or EIGRP stub routers.






21. Neighbor Advertisement.






22. An alternative software loaded into a Cisco router - used for basic IP connectivity; most useful when Flash memory is broken and you need IP connectivity to copy a new IOS image into Flash memory.






23. A subset of a classful IP network - as defined by a subnet mask - which used to address IP hosts on the same Layer 2 network in much the same way as a classful network is used.






24. A problem that occurs when an AS does not run BGP on all routers - with synchronization disabled. The routers running BGP may believe they have working routes to reach a prefix - and forward packets to internal routers that do not run BGP and do not






25. As defined in RFC 3623 - graceful restart allows for uninterrupted forwarding in the event that an OSPF router's OSPF routing process must restart. The router does this by first notifying the neighbor routers that the restart is about to occur; the n






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






27. Forwarding Equivalence Class.






28. Jargon referring to a policer action through which - instead of discarding an out-of-contract packet - the policer marks a different IPP or DSCP value - allowing the packet to continue on its way - but making the packet more likely to be discarded la






29. The Lempel Ziv STAC compression algorithm is used in Frame Relay networks to define dynamic dictionary entries that list a binary string from the compressed data and an associated smaller string that represents it during transmission






30. Router Advertisement.






31. A method for how a TCP sender grows its calculated CWND variable - thereby growing the allowed window for the connection. Slow Start grows CWND at an exponential rate.






32. Smoothed Round-Trip Time.






33. 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.






34. An MPLS term referring to any device that can forward packets that have MPLS labels.






35. 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.






36. 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.






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






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






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






40. Rendezvous point.






41. A protection against problems caused by unidirectional links between two switches. Uses messaging between switches to detect the loop - err-disabling the port when the link is unidirectional.






42. Link Fragmentation and Interleaving.






43. An event in which a new packet arrives - needing to be placed into a queue - and the queue is full






44. Provider edge.






45. An MPLS application that allows the MPLS network to connect to multiple different IP networks - with overlapping IP addresses - and provide IP connectivity to those multiple networks.






46. Auto-Rendezvous Point. Cisco-proprietary protocol that can be used to designate an RP and send RP-Announce messages that advertise its IP address and groups. Also - it can be used to designate a mapping agent that interprets what IP address RP is adv






47. The two computers use a protocol with which to communicate with the same layer on another computer. The protocol defined by each layer uses a header that is transmitted between the computers to communicate what each computer wants to do.






48. Rapid Spanning Tree Protocol.






49. The first 6 bits of the DS field - used for QoS marking.






50. An MPLS data structure used for forwarding labeled packets. The LFIB lists the incoming label - which is compared to the incoming packet's label - along with forwarding instructions for the packet.
