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. A contiguous group of data links that share the same OSPF area number.






2. Link-state database.






3. Layer 2 payload compression.






4. Per-Hop Behavior.






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






6. Jargon referring to any queue that receives priority service - often used for queues in an LLQ configuration that have the priority command configured.






7. 16 bits between the interface ID and global routing prefix in an IPv6 global address - used for subnet assignment inside an enterprise.






8. Inside telcos' original TDM hierarchy - the smallest unit of transmission at 64 kbps.






9. Prefix list.






10. Network Layer Protocol ID is a field in the RFC 2427 header that is used as a Protocol Type field in order to identify the type of Layer 3 packet encapsulated inside a Frame Relay frame.






11. Static length subnet masking.






12. An MPLS application that allows the MPLS network to connect to multiple different IP networks - with overlapping IP addresses - and provide IP connectivity to those multiple networks.






13. In two-rate policing - the second and higher rate defined to the policer.






14. Rendezvous point.






15. A mapping between each DSCP value and a corresponding CoS value - often used in Cisco LAN switches when performing classification for egress queuing.






16. In the PIM-SM design - the process by which a source DR - after it starts to receive the group traffic - encapsulates the multicast packets in the unicast packets and sends them to the RP.






17. IP Control Protocol.






18. Defined in IEEE 802.1w - a specification to enhance the 802.1d standard to improve the speed of STP convergence.






19. Challenge Handshake Authentication Protocol.






20. A vendor consortium that formerly worked to further Frame Relay common vendor standards.






21. In 802.1X - the computer that stores usernames/passwords and verifies that the correct values were submitted before authenticating the user.






22. A wireless LAN that only includes wireless users and no access points. 802.11 data frames in an ad hoc network travel directly between wireless users.






23. 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.






24. Link Aggregation Control Protocol.






25. A local Cisco-proprietary BGP setting that is not advertised to any peers. A larger value is considered to be better.






26. 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






27. Sent by a PIM router - by default every 30 seconds - on every interface on which PIM is configured to discover neighbors - establish adjacency - and maintain adjacency.






28. The mandatory contention-based 802.11 access protocol that is also referred to as CSMA/CA.






29. A workstation or server configured to collect and present RMON data for reporting purposes.






30. EIGRP (and IGRP) allows for the use of bandwidth - load - delay - MTU - and link reliability; the K values refer to an integer constant that includes these five possible metric components. Only bandwidth and delay are used by default - to minimize re






31. The password required by the enable command. Also - this term may specifically refer to the password defined by the enable password command.






32. With PIM on a multiaccess network - the PIM router with the highest IP address on the subnet. It is also the IGMPv1 Querier. The DR is responsible for the following tasks: - Sending PIM register and PIM join and prune messages toward the RP to infor






33. The range 233.0.0.0 through 233.255.255.255 that IANA has reserved (RFC 2770) on an experimental basis. It can be used by anyone who owns a registered autonomous system number to create 256 global multicast addresses.






34. Network Time Protocol.






35. 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






36. A dotted-decimal number that represents a subnet. It is the lowest numeric value in the range of IP addresses implied by a subnet number and prefix/mask.






37. A DiffServ PHB that defines eight values that provide backward compatibility with IP Precedence.






38. A standard (RFC 3768) feature by which multiple routers can provide interface IP address redundancy so that hosts using the shared - virtual IP address as their default gateway can still reach the rest of a network even if one or more routers fail.






39. The RFC 1997 name for the reserved COMMUNITY path attribute known to Cisco IOS as LOCAL_AS. (See LOCAL_AS.)






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






41. 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.






42. Regeneration of the Layer 2 encapsulation removed from frames forwarded in a SPAN session.






43. A standard (RFC 903) protocol by which a LAN-attached host can dynamically broadcast a request for a server to assign it an IP address. See also ARP.






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






45. The process of taking the payload inside a Layer 2 frame - including the headers of Layer 3 and above - compressing the data - and then uncompressing the data on the receiving router.






46. Temporal Key Integrity Protocol.






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






48. Another term for Port Address Translation. See PAT.






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






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