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. Defines a particular behavior for FTP regarding the establishment of data TCP connections. In active mode - the FTP client uses the FTP PORT command - over the FTP control connection - to tell the FTP server the port on which the client should be lis






2. The destination VLAN for an RSPAN session.






3. Port Aggregation Protocol.






4. A Layer 3 forwarding path through a router that does not optimize the forwarding path through the router.






5. The most recent standardized set of generic SNMP MIB variables - defined in RFC 1213 and updated in RFCs 2011 through 2013.






6. 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






7. 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.






8. An interface on a Cisco IOS-based switch that is treated as if it were an interface on a switch.






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






10. In shaping and policing - commonly used to refer to the shaping or policing rate. For WAN services - a common reference to the bit rate defined in the WAN service business contract for each VC.






11. Assured Forwarding. A set of DiffServ PHBs that defines 12 DSCP values - with four queuing classes and three drop probabilities within each queuing class.






12. In OSPF - a router that is prepared to take over the designated router.






13. 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.






14. An EIGRP message that is used to acknowledge reliable EIGRP messages - namely Update - Query - and Reply messages. Acks do not require an Ack.






15. A Cisco IOS configuration tool - using the ip as-path access-list command - that defines a list of statements that match the AS_PATH BGP path attribute using regular expressions.






16. An integer setting for EIGRP and IGRP. Any FS route whose metric is less than this variance multiplier times the successor's metric is added to the routing table - within the restrictions of the maximum-paths command.






17. 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.






18. A Cisco router feature in which the router works to prevent SYN attacks either by monitoring TCP connections flowing through the router - or by actively terminating TCP connection until the TCP connection is established and then knitting the client-s






19. Copper cable with RJ-45 connectors in which a twisted pair at pins 1 -2 on the first end of the cable is connected to pins 3 -6 on the other end - with a second pair connected to pins 3 -6 on the first end and pins 1 -2 on the other end.






20. A type of routing protocol convergence event in which the metric for a route increases slightly over time because of the advertisement of an invalid route.






21. The process of forwarding packets through a router. Also called IP forwarding.






22. Defined in RFC 3748 - the protocol used by IEEE 802.1X for exchanging authentication information.






23. A group of devices on one or more LANs that are configured (using management software) so that they can communicate as if they were attached to the same wire - when - in fact - they are located on a number of different LAN segments. Because VLANs are






24. Spanning Tree Protocol.






25. An 802.1w RSTP port state in which the port is an alternative Designated Port on some LAN segment.






26. A term referring to how a router views a BGP peer relationship - in which the peer is in another AS.






27. Link Aggregation Control Protocol.






28. The Cisco IOS Router IP Traffic Export feature - intended for intrusion detection - exports IP traffic that has signs of an attack - such as duplicate IP packets simultaneously received on two or more of a router's interfaces.






29. The protocol used in IPv6 for many functions - including address autoconfiguration - duplicate address detection - router - neighbor - and prefix discovery - neighbor address resolution - and parameter discovery.






30. Password Authentication Protocol.






31. A BGP ASN whose value is between 64 -512 and 65 -535. These values are not assigned for use on the Internet - and can be used for private purposes - typically either within confederations or by ISPs to hide the ASN used by some customers.






32. Variable-length subnet masking.






33. Loss of Frame.






34. A state variable kept by a router for each known neighbor or potential neighbor.






35. When a PIM-SM router switches from RPT to SPT - it sends a PIM-SM Prune message for the source and the group with the RP bit set to its upstream router on the shared tree. RFC 2362 uses the notation PIM-SM (S - G) RP-bit Prune for this message.






36. A term generally describing characteristics about BGP paths that are advertised in BGP Updates.






37. A set of all devices that receive broadcast frames originating from any device within the set. Devices in the same VLAN are in the same broadcast domain.






38. A Cisco IOS interface setting - as a percentage between 1 and 99 - that defines how much of the interface's bandwidth setting may be allocated by a queuing tool. The default value is 75 percent.






39. 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






40. A Cisco-proprietary Layer 2 protocol that enables a router to communicate to a switch which multicast group traffic the router does and does not want to receive from the switch.






41. Per-VLAN Spanning Tree Plus.






42. A Cisco switch feature that permits limiting traffic arriving at switch ports by percentage or absolute bandwidth. Separate thresholds are available per port for unicast - multicast - and broadcast traffic.






43. An 802.11 frame that access points or stations in ad hoc networks send periodically so that wireless stations can discover the presence of a wireless LAN and coordinate use of certain protocols - such as power-save mode.






44. A WRED process by which WRED discards all newly arriving packets intended for a queue - based on whether the queue's maximum threshold has been exceeded.






45. A type of OSPF NSSA area for which neither external (type 5) LSAs are introduced - nor type 3 summary LSAs; instead - the ABRs originate and inject default routes into the area. External routes can be injected into a totally NSSA area.






46. Link-state database.






47. Smoothed Round-Trip Time.






48. The process of taking the IP and TCP headers of a packet - compressing them - and then uncompressing them on the receiving router.






49. A 1-byte field in the IP header - originally defined by RFC 791 for QoS marking purposes.






50. Dynamic ARP Inspection.
