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 54-Mbps data rates using OFDM in the 5-GHz band.






2. 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.






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






4. 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.






5. A type of AS_PATH segment consisting of an unordered list of ASNs consolidated from component subnets of a summary BGP route.






6. With EIGRP - the metric (distance) of a route as reported by a neighboring router.






7. Defined in FRF.11 - an FR VC that uses a slightly varied header - as compared with FRF.3 data VCs - to accommodate voice payloads directly encapsulated inside the Frame Relay LAPF header.






8. Defined in IEEE 802.1d - a protocol used on LAN bridges and switches to dynamically define a logical network topology that allows all devices to be reached - but prevents the formation of loops.






9. Voice over Frame Relay.






10. Internal BGP.






11. In MPLS VPNs - a 64-bit Extended Community path attribute attached to a BGP route for the purpose of controlling into which VRFs the route is added.






12. Dynamic Multipoint VPN.






13. Class-Based Marking.






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






15. Class Selector.






16. An enhanced version of T1 framing - as compared with the earlier Superframe (D4) standard.






17. The innermost MPLS header in an packet traversing an MPLS VPN - with the label value identifying the forwarding details for the egress PE's VRF associated with that VPN.






18. A BGP router that - unknown to it - is aided by a route reflector server to cause all iBGP routers in an AS to learn all eBGP-learned prefixes.






19. Congestion window.






20. Three core security functions.






21. The signal strength of the RF signal at the output of the radio card or access point transmitter - before being fed into the antenna. Measured in milliwatts - watts - or dBm.






22. 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.






23. Prefix list.






24. A basic form of traffic shaping that is applied to an interface or subinterface. By default - it shapes all traffic leaving the interface - but can be modified by using an access control list. The access list controls only what traffic is shaped; GTS






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






26. Calculated measurement based on the actual queue depth and the previous average. Designed to allow WRED to adjust slowly to rapid changes of the actual queue depth.






27. Temporal Key Integrity Protocol.






28. Finish time.






29. A predefined VC. A PVC can be equated to a leased line in concept.






30. An IP variable that defines the largest size allowed in an IP packet - including the IP header. IP hosts must support an MTU of at least 576 bytes.






31. An issue whereby parts of the RF signal take different paths from the source to the destination - which causes direct and reflected signals to reach the receiver at different times - and corresponding bit errors.






32. An OSPF router that connects to the backbone area and to one or more non-backbone area.






33. The process of sending an infinite-metric route in routing updates when that route fails.






34. The one VLAN on an 802.1Q trunk for which the endpoints do not add the 4-byte 802.1Q tag when transmitting frames in that VLAN.






35. When a Query is received from a router - each host randomly picks a time between 0 and the Maximum Response Time period to send a Report. When the host with the smallest time period first sends the Report - the rest of the hosts suppress their report






36. Cisco-proprietary STP feature in which a switch port monitors for STP BPDUs of any kind - err-disabling the port upon receipt of any BPDU.






37. A term referring to the processes and bits in the data stream used to manage the Telco TDM hierarchy.






38. A method of collecting traffic received on a switch port or a VLAN and sending it to specific destination ports on the same switch.






39. A term referring generically to a server that performs many AAA functions. It also refers to the software product Cisco Secure Access Control Server.






40. A serial-line encoding standard that substitutes Bipolar Violations in a string of eight binary 0s to provide enough signal transitions to maintain synchronization.






41. RFC 1918-defined IPv4 network numbers that are not assigned as public IP address ranges - and are not routable on the Internet. Intended for use inside enterprise networks.






42. With DiffServ - a DSCP marking and a related set of QoS actions applied to packets that have that marking.






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






44. This term has two BGP-related definitions. First - it is the normal process in which a router - before sending an Update to an eBGP peer - adds its local ASN to the beginning of the AS_PATH path attribute. Second - it is the routing policy of purpose






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






46. A multicast routing protocol that operates in dense mode and depends on the OSPF unicast routing protocol to perform its multicast functions.






47. A commonly used name for Multi-VRF CE.






48. A method of applying a mathematical formula - with input including a private key - the message contents - and sometimes a shared text string - with the resulting digest being included with the message. The sender and the receiver perform the same mat






49. 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






50. The second byte of the IP header - formerly known as the ToS byte and redefined by DiffServ.
