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. 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.






2. In BGP - a feature in which BGP routes cannot be considered to be a best route to reach an NLRI unless that same prefix exists in the router's IP routing table as learned via some IGP.






3. A possible side effect of a scheduler that performs strict-priority scheduling of a queue - which can result in lower-priority queues getting little or no service.






4. Hot Standby Router Protocol.






5. A PPP feature used to load balance multiple parallel links at Layer 2 by fragmenting frames - sending one frame over each of the links in the bundle - and reassembling them at the receiving end of the link.






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






7. A BGP path attribute that lists the next-hop IP address used to reach an NLRI.






8. Spanning Tree Protocol.






9. Gateway Load Balancing Protocol.






10. Advanced Encryption Standard A superior encryption mechanism that is part of the 802.11i standard and has much stronger security than TKIP.






11. The practice of defining boundaries that determine how far multicast traffic will travel in your network.






12. The SNMP specifications - standardized in RFCs - defining the rules by which SNMP MIB variables should be defined.






13. Class of Service.






14. Point-to-Point Protocol.






15. A CBWFQ and LLQ term referring to the bandwidth on an interface that is neither reserved nor allocated via a priority command.






16. Used by a policer to classify packets relative to the traffic contract. These packets are considered to be above the traffic contract in all cases.






17. Context-Based Access Control.






18. 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.






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






20. A well-known discretionary BGP path attribute that flags a route as being a summary route.






21. Loss of Frame.






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






23. 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






24. Shaped round-robin.






25. An IPv6/IPv4 tunneling method that allows isolated IPv6 domains to be connected over an IPv4 network.






26. Multilink PPP.






27. 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






28. A reserved value for the BGP COMMUNITY path attribute that implies that the route should not be advertised outside the local AS.






29. Virtual LAN.






30. When subnetting a class A - B - or C address - the subnet for which all subnet bits are binary 0.






31. 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






32. A T1 alarm state that occurs when the receiver can no longer consistently identify the frame. See LOF.






33. A route that is created to represent one or more smaller component routes - typically in an effort to reduce the size of routing and topology tables.






34. The structure inside telcos' original digital circuit build-out in the mid-1900s - based upon using TDM to combine and disperse smaller DS levels into larger levels - and vice versa.






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






36. A WRED process by which WRED does not discard packets during times in which a queue's minimum threshold has not been passed.






37. In MPLS - a term used to define a label that an LSR allocates and then advertises to neighboring routers. The label is considered "local" on the router that allocates and advertises the label.






38. With routing protocols - the measurement of favorability that determines which entry will be installed in a routing table if more than one router is advertising that exact network and mask.






39. 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.






40. With RIP - a per-route timer that increases until the router receives a routing update that confirms the route is still valid - upon which the timer is reset to 0. If the updates cease - the Invalid timer will grow - until reaching the timer setting






41. The protocol used by content engines to manage traffic flow between routers configured for WCCP and between content engines. WCCP takes advantage of the fact that many web pages (and other content) are regularly accessed by users in a given network.






42. Customer edge.






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. 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.






45. Cisco-proprietary STP feature in which an access layer switch is configured to be unlikely to become Root or to become a transit switch. Also - convergence upon the loss of the switch's Root Port takes place in a few seconds.






46. Message Digest 5.






47. Virtual Routing and Forwarding table.






48. Allows the router to act as an inline IPS - doing deep packet inspection.






49. A calculated TCP variable - used along with the TCP CWND variable - to dictate a TCP sender's behavior when it recognizes packet loss. As CWND grows after packet loss - the TCP sender increases CWND based on Slow Start rules - until CWND grows to be






50. An EIGRP message that is used by a router to notify its neighbors when the router is gracefully shutting down.
