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 type of AS_PATH segment consisting of an ordered list of ASNs through which the route has been advertised.






2. 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.






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






4. Orthogonal frequency division multiplexing.






5. An administrative setting - included in Hellos - that is the first criteria for electing a DR. The highest priority wins - with values from 1-255 - with priority 0 meaning a router cannot become DR or BDR.






6. Any OSPF neighbor for which the database flooding process has completed.






7. Forward Explicit Congestion Notification.






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






9. Extended Superframe.






10. Often used synonymously with neighbor - but with emphasis on the fact that all required parameters match - allowing routing updates to be exchanged between the routers.






11. A Cisco-proprietary protocol used to dynamically negotiate whether the devices on an Ethernet segment want to form a trunk and - if so - which type (ISL or 802.1Q).






12. 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.






13. A characterization of a BGP path attribute in which BGP implementations are not required to support the attribute (optional) - and for which if a router receives a route with such an attribute - the router should forward the attribute unchanged (tran






14. Operates in dense mode and depends on its own unicast routing protocol that is similar to RIP to perform its multicast functions.






15. The second most significant bit in the most significant byte of an Ethernet MAC address - a value of binary 0 implies that the address is a Universally Administered Address (UAA) (also known as Burned-In Address [BIA]) - and a value of binary 1 impli






16. AutoQoS is a macro that creates and applies quality of service configurations based on Cisco best-practice recommendations.






17. The RMON function of tracking a particular variable. RMON events trigger RMON alarms.






18. Port Aggregation Protocol.






19. Instead of advertising all routes out a particular interface - the routing protocol omits the routes whose outgoing interface field matches the interface out which the update would be sent.






20. A T1 alarm state that occurs when a device receives a Yellow Alarm signal. This typically means that the device on the other end of the line is in a Red Alarm state.






21. A term used in this book to refer to a route that is included in a larger summary route.






22. From a Layer 1 perspective - the process of using special strings of electrical signals over a transmission medium to inform the receiver as to which bits are overhead bits - and which fit into individual subchannels.






23. Ethernet feature in which a NIC or Ethernet port can both transmit and receive at the same instant in time. It can be used only when there is no possibility of collisions. Loopback circuitry on NIC cards is disabled to use full duplex.






24. A 64-bit extension to the BGP NLRI field - used by MPLS for the purpose of making MPLS VPN customer routes unique in spite of the possibility of overlapping IPv4 address spaces in different customer networks.






25. 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






26. An Internet standard serial data-link protocol - used on synchronous and asynchronous links - that provides data-link framing - link negotiation - Layer 3 interface features - and other functions.






27. Inverse ARP.






28. Maximum Segment Size.






29. VLAN Trunking Protocol.






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






31. The process of taking routes known through one routing protocol and advertising those routes with another routing protocol.






32. Defined in IEEE 802.1s - a specification for multiple STP instances when using 802.1Q trunks






33. A characterization of a BGP path attribute in which BGP implementations are not required to support the attribute (optional) - and for which if a router receives a route with such an attribute - the router should remove the attribute before advertisi






34. 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.






35. A Cisco IOS configuration tool for RIP and EIGRP for which the list matches routes in routing updates - and adds a defined value to the sent or received metric for the routes. The value added to the metric is the offset.






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






37. Any other router - sharing a common data link - with which a router exchanges Hellos - and for which the parameters in the Hello pass the parameter-check process.






38. Committed Burst.






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






40. The destination VLAN for an RSPAN session.






41. Message sent by a PIM-DM router to its upstream router asking to quickly restart forwarding the group traffic; sent using the unicast address of the upstream router.






42. A list of interspersed alphanumeric literals and metacharacters that are used to apply complex matching logic to alphanumeric strings. Often used for matching AS_PATHs in Cisco routers.






43. In MPLS - a term used to define a label that an LSR allocates and then advertises to neighboring routers. The label is considered "local" on the router that allocates and advertises the label.






44. A router that should either permanently or temporarily not be used as a transit router. Can wait a certain time after OSPF process start - or after BGP notifies OSPF that BGP has converged - before ceasing to be a stub router.






45. Jargon referring to a policer action through which - instead of discarding an out-of-contract packet - the policer marks a different IPP or DSCP value - allowing the packet to continue on its way - but making the packet more likely to be discarded la






46. Provides dynamic inspection of traffic as it traverses the router. It uses Context-Based Access Control (CBAC) to look deeper into a packet than an access list can. It tracks outbound traffic and dynamically allows in responses to that traffic.






47. Another term for summary route.






48. Generic routing encapsulation.






49. Message Digest 5.






50. A set of all devices for which any frame sent by one of the devices would collide with any frames transmitted at the same time by any of the other devices in the set.
