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 path attribute that lists ASNs through which the route has been advertised. The AS_PATH includes four types of segments: AS_SEQ - AS_SET - AS_CONFED_SEQ - and AS_CONFED_SET. Often - this term is used synonymously with AS_SEQ






2. The MD5-encoded password defined by the enable secret command.






3. Link Fragmentation and Interleaving.






4. The process of forwarding packets through a router. Also call IP routing.






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






6. A switch feature that examines incoming frames - comparing the source IP and MAC addresses to the DHCP snooping binding database - filtering frames whose addresses are not listed in the database for the incoming interface.






7. Point-to-Point Protocol.






8. The notation in a Cisco IOS IP routing table that identifies the route used by that router as the default route.






9. The PDU used by a particular layer of a networking model - with x defining the layer.






10. Measured Round-Trip Time.






11. A Cisco-proprietary feature by which multiple routers can provide interface IP address redundancy - as well as cause a set of clients to load-balance their traffic across multiple routers inside the GLBP group.






12. Any other router - sharing a common data link - with which a router exchanges Hellos - and for which the parameters in the Hello pass the parameter-check process.






13. The process of taking the IP - UDP - and RTP headers of a voice or video packet - compressing them - and then uncompressing them on the receiving router.






14. An interface on a Cisco IOS-based switch that is treated as if it were an interface on a switch.






15. 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.






16. A BGP feature by which a router learns iBGP routes - and then forwards them to other iBGP peers - reducing the required number of iBGP peers while also avoiding routing loops.






17. Flush timer.






18. VTP process that prevents the flow of broadcasts and unknown unicast Ethernet frames in a VLAN from being sent to switches that have no ports in that VLAN.






19. A NAT term describing the process of multiplexing TCP and UDP flows - based on port numbers - to a small number of public IP addresses. Also called NAT overloading.






20. 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






21. Common Spanning Tree.






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






23. Aka network layer reachability information.






24. A style of attack in which an ICMP Echo is sent with a directed broadcast (subnet broadcast) destination IP address - and a source address of the host that is being attacked. The attack can result in the Echo reaching a large number of hosts - all of






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






26. Multilink PPP.






27. In two-rate policing - the second and higher rate defined to the policer.






28. Message sent by a PIM-DM router to its upstream router asking to quickly restart forwarding the group traffic; sent using the unicast address of the upstream router.






29. A type of logic for how a router uses a default route. When a default route exists - and no more specific match is made between the destination of the packet and the routing table - the default route is used.






30. A NAT term describing an IP address representing a host that resides outside the enterprise network - with the address being used in packets inside the enterprise network.






31. 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.






32. 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.






33. Data communications equipment.






34. A name used for DS1 lines inside the European TDM hierarchy.






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






36. A conceptual model used by CB Policing when using an excess burst.






37. A Cisco IOS configuration tool for RIP and EIGRP for which the list matches routes in routing updates - and adds a defined value to the sent or received metric for the routes. The value added to the metric is the offset.






38. Cell Loss Priority.






39. Defines a particular behavior for FTP regarding the establishment of data TCP connections. In active mode - the FTP client uses the FTP PORT command - over the FTP control connection - to tell the FTP server the port on which the client should be lis






40. Rendezvous point.






41. Loss of Signal. A T1 alarm state that occurs when the receiver has not received any pulses of either polarity for a defined time period.






42. A field in the IP header that is decremented at each pass through a Layer 3 forwarding device.






43. With EIGRP - a timer started when a reliable (to be acknowledged) message is transmitted. For any neighbor(s) failing to respond in its RTO - the RTP protocol causes retransmission. RTO is calculated based on SRTT.






44. A 16-bit number set with a router config-register command. It is used to set several low-level features related mainly to accessing the router and what the router does when powered on.






45. Label Switch Router.






46. A conceptual model used by shapers and policers to represent their internal logic.






47. The definitions for a particular set of data variables - with those definitions following the SMI specifications. See also SMI.






48. In the PIM-SM design - the process by which a PIM-SM router can build the SPT between itself and the source of a multicast group and take advantage of the most efficient path available from the source to the router as long as it has one directly conn






49. Penultimate hop popping.






50. 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
