Test your basic knowledge |

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. An 802.1w RSTP port state in which the port is not forwarding or receiving; covers 802.1d port states disabled - blocking - and listening.






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






3. A queue created by Cisco IOS as a result of the configuration of a queuing tool.






4. The RMON function of sending a notification to an RMON collector or the console. Triggered by an RMON event.






5. The data structure used by OSPF to hold LSAs.






6. A Cisco-proprietary STP implementation - created many years before IEEE 802.1s and 802.1w - that speeds convergence and allows for one STP instance for each VLAN.






7. The 32-bit number used to represent an OSPF router.






8. An OSPF external route for which internal OSPF cost is not added to the cost of the route as it was redistributed into OSPF.






9. One-time password.






10. A component of the IOS IP SLA feature. An IP SLA responder is a router configured to respond to a particular IP SLA message initiated by another router - allowing the routers to work together to provide performance information including UDP jitter an






11. Web Cache Communication Protocol.






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






13. 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.






14. Link Control Protocol.






15. Aka receiver's advertised window.






16. A set of packets in an MPLS network for which the MPLS network will apply the exact same forwarding behavior.






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






18. 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.






19. Defined in RFC 1631 - a method of translating IP addresses in headers with the goal of allowing multiple hosts to share single public IP addresses - thereby reducing IPv4 public address depletion.






20. 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.






21. A Cisco-proprietary LMI protocol - implemented in Cisco WAN switches and routers - through which the switch can inform the router about parameters for each VC - including CIR - Bc - and Be.






22. The definitions for a particular set of data variables - with those definitions following the SMI specifications. See also SMI.






23. A type of logic for how a router uses a default route. When a default route exists - and the class A - B - or C network for the destination IP address does not exist in the routing table - the default route is used. If any part of that classful netwo






24. Type of Service byte.






25. An IPv6 address type that is used by a number of hosts in a network that are providing the same service. Hosts accessing the service are routed to the nearest host in an anycast environment based on routing protocol metrics.






26. Challenge Handshake Authentication Protocol.






27. 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.






28. A network/subnet over which two or more OSPF routers have become neighbors - thereby being able to forward packets from one router to another across that network.






29. Protocol Independent Multicast sparse-mode routing protocol.






30. 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.






31. 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.






32. A Cisco IOS interface software queue queuing strategy implemented automatically when using either form of Frame Relay fragmentation. The system then interleaves packets from the high-priority queue between fragments of the medium-priority queue.






33. 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.






34. An architecture and set of documents that defines Cisco's best recommendations for how to secure a network.






35. The command used to initialize a SPAN or RSPAN session on a Catalyst switch.






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






37. 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.






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






39. Edge LSR.






40. Database Description.






41. WRED compares this setting to the average queue depth to decide whether packets should be discarded. All packets are discarded if the average queue depth rises above this maximum threshold.






42. In the context of SNMP - the Get command is sent by an SNMP manager - to an agent - requesting the value of a single MIB variable identified in the request. The Get request identifies the exact variable whose value the manager wants to retrieve. Intr






43. A designated router that is directly connected with a source of the multicast group.






44. The router in a VRRP group that is currently actively forwarding IP packets. Conceptually the same as an HSRP Active router.






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






46. Designated router.






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






48. 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






49. A NAT term describing an IP address representing a host that resides inside the enterprise network - with the address being used in packets inside the enterprise network.






50. 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.
