CCIE Vocab

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. Internal BGP.






2. With Spanning Tree Protocol - the single port on each LAN segment from which the best Hello BPDU is forwarded.






3. In the context of SNMP - the Response command is sent by an SNMP agent - back to a manager - in response to any of the three types of Get requests - or in response to a Set request. It is also used by a manager in response to a received Inform comman






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






5. On a serial cable - the pin lead set by the DTE to imply that the DTE is ready to signal using pin leads.






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






7. A single instance of STP that is applied to multiple VLANs - typically when using the 802.1Q trunking standard.






8. A prestandard (at the time of publication) wireless LAN physical layer that offers data rates in the hundreds of megabits per second.






9. The most significant bit in the most significant byte of an Ethernet MAC address - its value implies that the address is a unicast MAC address (binary 0) or not (binary 1).






10. A type of spread spectrum that spreads RF signals over the frequency spectrum by transmitting the signal at different frequencies according to a hopping pattern. One of the original 802.11 physical layers used FHSS to offer data rates of 1 and 2 Mbps






11. With EIGRP - the route to each destination for which the metric is the lowest of all known routes to that network.






12. Also known as triggered updates.






13. Defines a particular wireless LAN. The SSID configured in the radio card must match the SSID in the access point before the station can connect with the access point.






14. Jargon used to refer to the second of two buckets in the dual token bucket model; its size is Be.






15. Hot Standby Router Protocol.






16. Jargon used to refer to the first of two buckets in the dual token bucket model; its size is Bc.






17. A process on a computing device that issues requests for SNMP MIB variables from SNMP agents - receives and processes the MIB data - and accepts unsolicited Trap messages from SNMP agents.






18. An Internet standard authentication protocol that uses clear-text passwords and a two-way handshake to perform authentication over a PPP link.






19. Direct sequence spread spectrum.






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






21. 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.






22. With RIP - a per-route timer (default 180 seconds) that begins when a route's metric changes to a larger value.






23. Maximum Response Time.






24. A 3-bit field in the first 3 bits of the ToS byte in the IP header - used for QoS marking.






25. PIM-DM is a method of routing multicast packets that depends on a flood-and-prune approach. PIM Dense Mode gets its name from the assumption that there are many receivers of a particular multicast group - close together (from a network perspective).






26. A conceptual model used by shapers and policers to represent their internal logic.






27. AS number. 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.






28. Congestion window.






29. Per-VLAN Spanning Tree Plus.






30. On a serial cable - the pin lead set by the DTE to tell the DCE that the DTE wants to send data.






31. Cisco Express Forwarding.






32. A 16-bit number set with a router config-register command. It is used to set several low-level features related mainly to accessing the router and what the router does when powered on.






33. A BGP neighbor state in which the BGP neighbors have stabilized and can exchange routing information using BGP Update messages.






34. A BGP process by which a router reapplies routing policy configuration (route maps - filters - and the like) based on stored copies of sent and received BGP Updates.






35. 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.






36. Digital subscriber line - a common Internet service type for residential and business customers.






37. Area Border Router. An OSPF router that connects to the backbone area and to one or more non-backbone areas.






38. Maximum transmission unit.






39. Boot Protocol. A standard (RFC 951) protocol by which a LAN-attached host can dynamically broadcast a request for a server to assign it an IP address - along with other configuration settings - including a subnet mask and default gateway IP address.






40. The number of beacons that governs how often multicast frames are sent over a wireless LAN.






41. 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.






42. 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.






43. 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.






44. Spanning Tree Protocol.






45. With EIGRP - a router sharing the same primary subnet - with which Hellos are exchanged - parameters match - and with which routes can be exchanged.






46. A small FIFO queue associated with each router's physical interface - for the purpose of making packets available to the interface hardware - removing the need for a CPU interrupt to start sending the next packet out the interface.






47. A term referring generically to ways in which a router or switch can determine whether a particular device or user should be allowed access.






48. An early standard from AT&T for encoding analog voice as a digital signal for transmission over a TDM network. PCM requires 64 kbps - and is the basis for the DS0 speed.






49. Cisco IOS IP Service Level Agent feature. Provides for router-generated information useful for verifying network performance on a scheduled basis - and the associated reporting functions.






50. Router Advertisement.
