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 wireless LAN physical layer that operates at up to 11-Mbps data rates using DSSS in the 2.4-GHz band.






2. An OSPF external route for which internal OSPF cost is added to the cost of the route as it was redistributed into OSPF.






3. Bipolar Violation.






4. A BGP feature that defines the IP TTL field value in packets sent between two eBGP peers. This feature is required when using IP addresses other than the interface IP address on the link between peers.






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






6. A strategy for subnetting a classful network for which all masks/prefixes are the same value for all subnets of that one classful network.






7. The rate at which a shaper limits the bits exiting the shaper.






8. An optional transitive BGP path attribute that - for a summary route - lists the BGP RID and ASN of the router that created the summary.






9. 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.






10. A characterization of a BGP path attribute in which all BGP implementations must support and understand the attribute (well known) - but BGP Updates can either include the attribute or not depending on whether a related feature has been configured (d






11. 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.






12. Removing unwanted VLANs from a Layer 2 path.






13. A BGP path attribute that allows routers in one AS to set a value and advertise it into a neighboring AS - impacting the decision process in that neighboring AS. A smaller value is considered better. Also called the BGP metric.






14. Generic routing encapsulation.






15. A routing protocol feature by which the routing update includes the entire set of routes - even if some or all of the routes are unchanged.






16. A message sent by each host - either in response to a router Query or on its own - to all multicast groups for which it would like to receive multicast traffic.






17. Router Advertisement.






18. Aka network layer reachability information.






19. An OSPF area into which external (type 5) LSAs are not introduced by its ABRs; instead - the ABRs originate and inject default routes into the area.






20. A network/subnet to which only one OSPF router is connected.






21. The portion of PPP focused on features that are unrelated to any specific Layer 3 protocol.






22. Point-to-Point Protocol over Ethernet. A convention often used as the data link protocol over Cable in which Ethernet is used as the data link protocol - but with PPP being encapsulated inside Ethernet. The combination gives the data link features of






23. Cisco IOS router feature by which a route map determines how to forward a packet - typically based on information in the packet other than the destination IP address.






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






25. 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.






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






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






28. In the context of SNMP - the Inform command is sent by an SNMP manager to communicate a set of variables - and their values - to another SNMP manager. The main purpose is to allow multiple managers to exchange MIB information - and work together - wi






29. 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






30. Out of Frame.






31. Network Address Translation-Protocol Translation.






32. Exterior Gateway Protocol.






33. A number between 1 and 64 -511 (public) and 64 -512 and 65 -535 (private) assigned to an AS for the purpose of identifying a specific BGP domain.






34. In BGP - a configuration construct in which multiple neighbors' parameters can be configured as a group - thereby reducing the length of the configuration. Additionally - BGP performs routing policy logic against only one set of Updates for the entir






35. 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.






36. A set of QoS RFCs that redefines the IP header's ToS byte - and suggests specific settings of the DSCP field and the implied QoS actions based on those settings.






37. Inside telcos' original TDM hierarchy - a unit that combines multiple DS1s into a single channel






38. A router that should not be used to forward packets between other routers. Other routers will not send Query messages to a stub router.






39. Dynamic Trunking Protocol.






40. An address type in IPv6 networks that is used only on the local link and never beyond that scope.






41. Used to reserve network resources for a flow as it traverses the network. A device that creates an RSVP reservation guarantees that it can provide the bandwidth - latency - or other resources that are requested by RSVP.






42. Permanent virtual circuit.






43. Per-Hop Behavior.






44. An E-LSR in an MPLS VPN network whose role in a particular discussion is to receive unlabeled packets over customer links and then forward the packets as labeled packets into the MPLS network.






45. Variable name for the time interval used by shapers and by CAR.






46. In MPLS - a term used to define a label that an LSR learned from a neighboring LSR.






47. A table inside a router that holds the path attributes and NLRI known by the BGP implementation on that router.






48. A protocol - defined in RFC 2865 - that defines how to perform authentication between an authenticator (for example - a router) and an authentication server that holds a list of usernames and passwords.






49. Penultimate hop popping.






50. Context-Based Access Control.
