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






2. On a serial cable - the pin lead set by the DTE to imply that the DTE is ready to signal using pin leads.






3. From one perspective - DTE devices are one of two devices on either end of a communications circuit - specifically the device with less control over the communications. In Frame Relay - routers connected to a Frame Relay access link are DTE devices.






4. Data Terminal Ready.






5. Data Carrier Detect.






6. An IPv6 address format used for publicly registered IPv6 addresses.






7. A BGP neighbor state in which the BGP neighbors have stabilized and can exchange routing information using BGP Update messages.






8. 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.






9. A switch feature that limits the number of allowed MAC addresses on a port - with optional limits based on the actual values of the MAC addresses.






10. With RIP - a per-route timer - which is reset and grows with the Invalid timer. When the Flush timer mark is reached (default 240 seconds) - the router removes the route from the routing table - and now accepts any other routes about the failed subne






11. 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.






12. A vendor consortium that formerly worked to further Frame Relay common vendor standards.






13. A Cisco switch feature that allows separation of ports as if they were in separate VLANs - while allowing the use of a single IP subnet for all ports.






14. Data communications equipment.






15. Cell Loss Priority.






16. Regeneration of the Layer 2 encapsulation removed from frames forwarded in a SPAN session.






17. A type of logic for how a router uses a default route. When a default route exists - and no more specific match is made between the destination of the packet and the routing table - the default route is used.






18. 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






19. In IP routing - a term referring to the building of IP routing tables by IP routing protocols.






20. 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.






21. A bit in the LAPF Frame Relay header that - when set to 1 - implies that the frame has experienced congestion.






22. Three core security functions.






23. Aka minimum CIR.






24. A type of spread spectrum that spreads RF signals over the frequency spectrum by transmitting the signal at different frequencies according to a hopping pattern. One of the original 802.11 physical layers used FHSS to offer data rates of 1 and 2 Mbps






25. Multicast addresses that are not assigned by IANA.






26. Aka receiver's advertised window.






27. A set of parameters for CBAC to perform in its traffic inspection process.






28. The characterization of how far EIGRP Query messages flow away from the router that first notices a failed route and goes active for a particular subnet.






29. Per-VLAN Spanning Tree Plus.






30. A characterization of a BGP path attribute in which all BGP implementations must support and understand the attribute (well known) - but BGP Updates can either include the attribute or not depending on whether a related feature has been configured (d






31. A term used with Cisco LAN switches - referring to a DSCP value used when making QoS decisions about a frame. This value may not be the actual DSCP value in the IP header encapsulated inside the frame.






32. With RIP - a per-route timer (default 180 seconds) that begins when a route's metric changes to a larger value.






33. Part of the Cisco IOS Firewall feature set - CBAC inspects traffic using information in the higher-layer protocols being carried to decide whether to open the firewall to specific inbound traffic. CBAC supports both UDP and TCP and multiple higher-la






34. An EIGRP message that identifies neighbors - exchanges parameters - and is sent periodically as a keepalive function. Hellos do not require an Ack.






35. A term used with Cisco LAN switches - referring to a queue treated with strict-priority scheduling.






36. The second byte of the IP header - formerly known as the ToS byte and redefined by DiffServ.






37. Port Aggregation Protocol.






38. 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.






39. Loss of Signal. A T1 alarm state that occurs when the receiver has not received any pulses of either polarity for a defined time period.






40. Password Authentication Protocol.






41. 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.






42. Area Border Router. An OSPF router that connects to the backbone area and to one or more non-backbone areas.






43. An MPLS term referring to the MPLS label just before the IP header. Also called the VPN label when implementing MPLS VPNs.






44. In PIM-SM - the path of the group traffic that flows from the RP to the routers that need the traffic. It is also called the root-path tree (RPT) - because it is rooted at the RP.






45. A neighbor state that signifies the other router has reached neighbor status - having passed the parameter check. The FIB entry details the information needed for forwarding: the next-hop router and the outgoing interface - in an optimized mtrie stru






46. A routing protocol feature for which the routing protocol sends routing updates immediately upon hearing about a changed route - even though it may normally only send updates on a regular update interval.






47. Multicast Listener Discovery.






48. External BGP.






49. The range 239.0.0.0 through 239.255.255.255 that IANA has assigned for use in private multicast domains.






50. Digital Signal Level 1.
