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. The portion of PPP focused on negotiating IP features






2. With private VLANs - a secondary VLAN in which the ports can send and receive frames with each other - but not with ports in other secondary VLANS.






3. A type of OSPF packet used to exchange and acknowledge LSA headers. Sometimes called DBD.






4. Used to reserve network resources for a flow as it traverses the network. A device that creates an RSVP reservation guarantees that it can provide the bandwidth - latency - or other resources that are requested by RSVP.






5. A wireless LAN physical layer that is backward compatible with 802.11b and operates at up to 54-Mbps data rates using OFDM in the 2.4-GHz band.






6. The OSPF data structure that describes topology information.






7. A reserved value for the BGP COMMUNITY path attribute that implies that the route should not be advertised to any other peer.






8. Area 0; the area to which all other OSPF areas much connect in order for OSPF to work.






9. A term relating to Cisco LAN switch tail-drop logic - in which multiple tail-drop thresholds may be assigned based on CoS or DSCP - resulting in some frames being discarded more aggressively than others.






10. With EIGRP - the metric (distance) of a route as reported by a neighboring router.






11. A field within a route entry in a routing update - used to associate a generic number with the route. It is used when passing routes between routing protocols - allowing an intermediate routing protocol to pass information about a route that is not n






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






13. A component that interfaces with a phone using IP and provides connections to the Public Switched Telephone Network (PSTN).






14. An optional nontransitive BGP path attribute that lists the route reflector cluster IDs through which a route has been advertised - as part of a loop-prevention process similar to the AS_PATH attribute.






15. Measured Round-Trip Time.






16. A BGP feature that defines the IP TTL field value in packets sent between two eBGP peers. This feature is required when using IP addresses other than the interface IP address on the link between peers.






17. An OSPF external route for which internal OSPF cost is added to the cost of the route as it was redistributed into OSPF.






18. Version 6 of the IP protocol - which uses 128-bit IP addresses.






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






20. A T1 alarm state that occurs when the receiver can no longer consistently identify the frame. See LOF.






21. 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.






22. 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.






23. Cisco-proprietary VLAN trunking protocol.






24. Sequence number.






25. An exterior routing protocol that predates BGP. It is no longer used today.






26. An optimized Layer 3 forwarding path through a router. Fast switching optimizes routing table lookup by creating a special - easily searched table of known flows between hosts.






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






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






29. An optional transitive BGP path attribute used to store 32-bit decimal values. Used for flexible grouping of routes by assigning the group the same COMMUNITY value. Other routers can apply routing policies based on the COMMUNITY value. Used in a larg






30. The signal strength of the RF signal at the output of the radio card or access point transmitter - before being fed into the antenna. Measured in milliwatts - watts - or dBm.






31. The condition in which a route has been in an EIGRP active state for longer than the router's Active timer.






32. 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






33. A Cisco IOS queuing tool that uses MQC configuration commands and reserves a minimum bandwidth for each queue.






34. Link-state advertisement.






35. 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.






36. 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






37. Version 4 of the IP protocol - which is the generally deployed version worldwide (at publication) - and uses 32-bit IP addresses.






38. 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.






39. A category used by a policer to classify packets relative to the traffic contract. The bit rate implied by all conforming packets is within the traffic contract.






40. Policing in which two rates are metered - and packets are placed into one of three categories (conform - exceed - or violate).






41. An attack similar to a smurf attack - but using packets for the UDP Echo application instead of ICMP.






42. Point-to-Point Protocol over Ethernet. A convention often used as the data link protocol over Cable in which Ethernet is used as the data link protocol - but with PPP being encapsulated inside Ethernet. The combination gives the data link features of






43. Dynamic Host Configuration Protocol.






44. Label switched path.






45. In BGP - either external BGP (eBGP) - confederation eBGP - or internal BGP (iBGP). The term refers to a peer connection - and whether the peers are in different ASs (eBGP) - different confederation sub-ASs (confederation eBGP) - or in the same AS (iB






46. A possible side effect of a scheduler that performs strict-priority scheduling of a queue - which can result in lower-priority queues getting little or no service.






47. The two computers use a protocol with which to communicate with the same layer on another computer. The protocol defined by each layer uses a header that is transmitted between the computers to communicate what each computer wants to do.






48. In the context of SNMP - the Set command is sent by an SNMP manager - to an agent - requesting that the agent set a single identified variable to the stated value. The main purpose is to allow remote configuration and remote operation - such as shutt






49. A process whereby a switch - when making a forwarding decision - uses not only Layer 2 logic but other OSI layer equivalents as well.






50. Reliable Transport Protocol.
