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 single label and link that is part of a complete LDP. See also label switched path.






2. The same thing as TCP code bits. See TCP code bits.






3. A term used with Cisco LAN switches - referring to a queue treated with strict-priority scheduling.






4. Label Distribution Protocol.






5. A type of OSPF packet used to acknowledge LSU packets.






6. Network Based Application Recognition.






7. Low-latency queuing.






8. A field within a route entry in a routing update - used to associate a generic number with the route. It is used when passing routes between routing protocols - allowing an intermediate routing protocol to pass information about a route that is not n






9. Timer An STP timer that dictates how long a port should stay in the listening state and the learning state.






10. A reserved value for the BGP COMMUNITY path attribute that implies that the route should not be advertised to any other peer.






11. 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.






12. An 802.1d STP transitory port state in which the port does not send or receive frames - and does not learn MAC addresses - but does wait for STP convergence and for CAM flushing by the switches in the network.






13. An OSPF timer that determines how long an LSA can remain in the LSDB without having heard a reflooded copy of the LSA.






14. 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.






15. In wireless LANs - a mechanism that counters issues related to RF interference by dividing a larger 802.11 data frame into smaller frames that are sent independently to the destination. See also LFI.






16. 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.






17. Link Access Procedure for Frame-Mode Bearer Services.






18. A type of spread spectrum that spreads RF signals over the frequency spectrum by representing each data bit by a longer code. 802.11b specifies the use of DSSS.






19. 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.






20. Weighted tail drop.






21. An Internet standard authentication protocol that uses secure hashes and a three-way handshake to perform authentication over a PPP link.






22. Not-so-stubby area.






23. A numeric value between 0 and 32 (inclusive) that defines the number of beginning bits in an IP address for which all IP addresses in the same group have the same value. Alternative: The number of binary 1s beginning a subnet mask - written as a deci






24. 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.






25. Single-bit fields in the TCP header. For example - the TCP SYN and ACK code bits are used during connection establishment.






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






27. Clear To Send.






28. In IPv6 - the Neighbor Discovery message used by an IPv6 node to send information about itself to its neighbors.






29. In the context of SNMP - the GetNext command is sent by an SNMP manager - to an agent - requesting the value of a single MIB variable. The GetNext request identifies a variable for which the manager wants the variable name and value of the next MIB l






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






31. A Cisco IOS queuing tool most notable for its reservation of a minimum bandwidth for each queue.






32. A BGP feature that overcomes the requirement of a full mesh of iBGP peers inside a single AS by separating the AS into multiple sub-autonomous systems.






33. A VC that is set up dynamically when needed. An SVC can be equated to a dial-on-demand connection in concept.






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






35. Quantum value.






36. In switch port security - the process whereby the switch dynamically learns the MAC address(es) of the device(s) connected to a switch port - and then adds those addresses to the running configuration as allowed MAC addresses for port security.






37. A type of OSPF packet used to exchange and acknowledge LSA headers. Sometimes called DBD.






38. With shaping - the number of bits allowed to be sent every Tc. Also defines the size of the token bucket when Be = 0.






39. Label switched path.






40. With OSPF - the timer used to determine when a neighboring router has failed - based on a router not receiving any OSPF messages - including Hellos - in this timer period.






41. Used by WRED to calculate the rate at which the average queue depth changes as compared with the current queue depth. The larger the number - the slower the change in the average queue depth.






42. 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.






43. A characterization of a BGP path attribute in which BGP implementations are not required to support the attribute (optional) - and for which if a router receives a route with such an attribute - the router should forward the attribute unchanged (tran






44. An early T1 framing standard.






45. An EIGRP message that informs neighbors about routing information. Update messages require an Ack.






46. Cisco IOS Embedded Event Manager - a feature that monitors events on a router and reports their results. Principally intended to increase availability - EEM provides flexible - granular detection and alerting functions.






47. Provider edge.






48. A characteristic of OSPF interfaces that determines whether a DR election is attempted - whether or not neighbors must be statically configured - and the default Hello and Dead timer settings.






49. Copper cable with RJ-45 connectors in which a twisted pair at pins 1 -2 on the first end of the cable is connected to pins 3 -6 on the other end - with a second pair connected to pins 3 -6 on the first end and pins 1 -2 on the other end.






50. Similar to an appliance firewall - in that interfaces are placed into security zones. Traffic is allowed between interfaces in the same zone. You can apply policies to filter and control traffic between zones.
