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. Data Terminal Ready.






2. A configuration tool in Cisco IOS that allows basic programming logic to be applied to a set of items. Often used for decisions about what routes to redistribute - and for setting particular characteristics of those routes






3. The IEEE standardized protocol for VLAN trunking.






4. Link-State Refresh. A timer that determines how often the originating router should reflood an LSA - even if no changes have occurred to the LSA.






5. Message Digest 5.






6. A term referring to EIGRP's internal processing logic.






7. Cisco IOS Embedded Event Manager - a feature that monitors events on a router and reports their results. Principally intended to increase availability - EEM provides flexible - granular detection and alerting functions.






8. An FRF standard for LFI for data (FRF.3) VCs.






9. A method of collecting traffic received on a switch port or a VLAN and sending it to specific destination ports on a switch other than the one on which it was received.






10. 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.






11. With EIGRP - a timer started when a reliable (to be acknowledged) message is transmitted. For any neighbor(s) failing to respond in its RTO - the RTP protocol causes retransmission. RTO is calculated based on SRTT.






12. The single port on each nonroot switch upon which the best Hello BPDU is received.






13. With a routing update - or routing table entry - the portion of a route that defines the next router to which a packet should be sent to reach the destination subnet. With routing protocols - the Next Hop field may define a router other than the rout






14. A type of logic for how a router uses a default route. A convention for discussing and thinking about IP addresses by which class A - B - and C default network prefixes (of 8 - 16 - and 24 bits - respectively) are considered.






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






16. A field in the IP header that is decremented at each pass through a Layer 3 forwarding device.






17. The specific frequency subband on which the radio card or access point is operating. The RF channel is set in the access point or ad hoc stations.






18. 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).






19. Cisco-proprietary STP feature in which switches use messaging to confirm the loss of Hello BPDUs in a switch's Root Port - to avoid having to wait for maxage to expire - resulting in faster convergence.






20. 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






21. 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.






22. A bit inside the Frame Relay header that - when set - implies that congestion occurred in the direction opposite (or backward) as compared with the direction of the frame.






23. An 802.1d STP port state in which the port sends and receives frames.






24. Priority queue and priority queuing.






25. Cisco IOS router feature by which a route map determines how to forward a packet - typically based on information in the packet other than the destination IP address.






26. Rapid Spanning Tree Protocol.






27. 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.






28. A switch feature with which the switch watches ARP messages - determines if those messages may or may not be part of some attack - and filters those that look suspicious.






29. Secure Copy Protocol - one of the many ways of transferring files to and from Cisco IOS routers and switches.






30. 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.






31. The Lempel Ziv STAC compression algorithm is used in Frame Relay networks to define dynamic dictionary entries that list a binary string from the compressed data and an associated smaller string that represents it during transmission






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






33. A CBWFQ and LLQ term referring to the bandwidth on an interface that is neither reserved nor allocated via a priority command.






34. A term used with WFQ for the number assigned to a packet as it is enqueued into a WFQ. WFQ schedules the currently lowest SN packet next.






35. A security standard that includes both TKIP and AES and was ratified by the Wi-Fi Alliance.






36. A 3-bit field in an ISL header used for marking frames. Also - used generically to refer to either the ISL CoS field or the 802.1Q User Priority field.






37. With private VLANs - a secondary VLAN in which the ports can send and receive frames only with promiscuous ports in the primary VLAN.






38. An EIGRP router's reaction to an input event - leading to the use of a feasible successor or going active on a route.






39. Alarm Indication Signal. With T1s - the practice of sending all binary 1s on the line in reaction to problems - to provide signal transitions and allow recovery of synchronization and framing.






40. Jargon used by STP mostly when discussing the root election process; refers to a Hello with a lower bridge ID. Sometimes refers to a Hello with the same bridge ID as another - but with better values for the tiebreakers in the election process.






41. The notation in a Cisco IOS IP routing table that identifies the route used by that router as the default route.






42. A characteristic of OSPF interfaces that determines whether a DR election is attempted - whether or not neighbors must be statically configured - and the default Hello and Dead timer settings.






43. Cisco-proprietary VLAN trunking protocol.






44. Ethernet process by which devices attached to the same cable negotiate their speed and the duplex settings over the cable.






45. 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.






46. A Cisco IOS configuration tool that can be used to match routing updates based on a base network address - a prefix - and a range of possible masks used inside the values defined by the base network address and prefix.






47. Link-state database.






48. A BGP path attribute that lists ASNs through which the route has been advertised. The AS_PATH includes four types of segments: AS_SEQ - AS_SET - AS_CONFED_SEQ - and AS_CONFED_SET. Often - this term is used synonymously with AS_SEQ






49. An E-LSR in an MPLS VPN network whose role in a particular discussion is to receive unlabeled packets over customer links and then forward the packets as labeled packets into the MPLS network.






50. Alternate Mark Inversion. A serial-line encoding standard that sends alternating positive and negative 3-volt signals for binary 1 - and no signal (0 V) for binary 0.
