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. Permanent virtual circuit.






2. Modified Deficit Round-Robin.






3. Data Terminal Ready.






4. A standard (RFC 2131) protocol by which a host can dynamically broadcast a request for a server to assign to it an IP address - along with other configuration settings - including a subnet mask and default gateway IP address. DHCP provides a great de






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






6. A method of providing dynamically configured spoke-to-spoke VPN connectivity in a hub-and-spoke network that significantly reduces configuration required on the spoke routers compared to traditional IPsec VPN environments.






7. A protocol used for reliable multicast and unicast transmissions. Used by EIGRP.






8. Method by which a dense-mode routing protocol distributes multicast traffic from a source to all the segments of a network. Also called shortest-path tree (SPT) - because it uses the shortest routing path from the source to the segments of the networ






9. A Cisco switch feature that permits limiting traffic arriving at switch ports by percentage or absolute bandwidth. Separate thresholds are available per port for unicast - multicast - and broadcast traffic.






10. Multiple Spanning Trees.






11. An 802.1d STP port state in which the port sends and receives frames.






12. Network Address Translation-Protocol Translation.






13. 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






14. The IPv6 protocol used for the discovery of which hosts are listening for which multicast IP addresses for IPv6.






15. 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.






16. A group of devices on one or more LANs that are configured (using management software) so that they can communicate as if they were attached to the same wire - when - in fact - they are located on a number of different LAN segments. Because VLANs are






17. A Cisco-proprietary protocol used to dynamically negotiate whether the devices on an Ethernet segment want to form a trunk and - if so - which type (ISL or 802.1Q).






18. An individual line in an ACL.






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






20. An 802.1d STP port state in which the port has been administratively disabled.






21. Differentiated Services.






22. A BGP term referring to an IP prefix and prefix length.






23. In an IOS confederation configuration - the actual ASN as seen by eBGP peers.






24. 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






25. Defines a particular behavior for FTP regarding the establishment of TCP data connections. In passive mode - an FTP server uses the FTP PORT command - over the FTP control connection - to tell the FTP client the port on which the server will be liste






26. The operating mode of shaped round-robin that provides behavior like CBWFQ with bandwidth allocated between different traffic classes by a relative amount rather than absolute percentage of the available bandwidth.






27. Common Spanning Tree.






28. The range 232.0.0.0 through 232.255.255.255 that is allocated by IANA for SSM destination addresses and is reserved for use by source-specific applications and protocols.






29. 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.






30. The router that will receive the group traffic when a multicast router forwards group traffic to another router.






31. A WFQ term referring to its drop logic - which is similar to tail-drop behavior.






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






33. Records client authentication and roaming events - which are sent to the CiscoWorks Wireless LAN Solution Engine (WLSE) to monitor client associations to specific access points.






34. 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






35. Structure of Management Information.






36. Part of the Cisco IOS Firewall feature set - CBAC inspects traffic using information in the higher-layer protocols being carried to decide whether to open the firewall to specific inbound traffic. CBAC supports both UDP and TCP and multiple higher-la






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






38. 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.






39. Network Time Protocol.






40. A process whereby a switch - when making a forwarding decision - uses not only Layer 2 logic but other OSI layer equivalents as well.






41. Exterior Gateway Protocol.






42. The Cisco IOS Router IP Traffic Export feature - intended for intrusion detection - exports IP traffic that has signs of an attack - such as duplicate IP packets simultaneously received on two or more of a router's interfaces.






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






44. A table used by CEF that holds information about adjacent IP hosts to which packets can be forwarded.






45. A dotted-decimal number that represents a subnet. It is the lowest numeric value in the range of IP addresses implied by a subnet number and prefix/mask.






46. An IPv6 address type that is used by a number of hosts in a network that are providing the same service. Hosts accessing the service are routed to the nearest host in an anycast environment based on routing protocol metrics.






47. 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.






48. A wireless LAN that only includes wireless users and no access points. 802.11 data frames in an ad hoc network travel directly between wireless users.






49. A contiguous group of data links that share the same OSPF area number.






50. A serial-line encoding standard like B8ZS - but with each set of four consecutive 0s being changed to include a Bipolar Violation to maintain synchronization.
