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. 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.






2. 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.






3. A set of four hex digits listed in an IPv6 address. Each quartet is separated by a colon.






4. Clear To Send.






5. Data Carrier Detect.






6. 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






7. A type of OSPF packet - used to communicate LSAs to another router.






8. Feasible distance.






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






10. 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.






11. A term referring to the MQC service-policy command - which is used to enable a policy map on an interface.






12. Extensible Authentication Protocol.






13. Data terminal equipment.






14. Shaped round-robin.






15. A strategy for subnetting a classful network for which masks/prefixes are different for some subnets of that one classful network.






16. On a serial cable - the pin lead set by the DCE to imply a working link.






17. Aka Rapid Per-VLAN Spanning Tree Plus.






18. An IOS feature in which multiple routing tables and routing forwarding instances exist in a single router - with interfaces being assigned to one of the several VRFs. This feature allows separating of routing domains inside a single router platform.






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






20. Temporal Key Integrity Protocol.






21. The portion of PPP focused on negotiating IP features






22. With routing protocols - the process by which the router receiving a routing update determines if the routing update came from a trusted router.






23. Class-Based Marking.






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






25. A method of Link Fragmentation and Interleaving (LFI) over interfaces that natively use Frame Relay encapsulation. The routers first build MLP-style PPP headers - which are then encapsulated inside a Frame Relay header. The PPP headers are then used






26. Virtual LAN.






27. A 1-byte field in the IP header - originally defined by RFC 791 for QoS marking purposes.






28. A term generally describing characteristics about BGP paths that are advertised in BGP Updates.






29. The one VLAN on an 802.1Q trunk for which the endpoints do not add the 4-byte 802.1Q tag when transmitting frames in that VLAN.






30. Label Switch Router.






31. The MPLS feature by which an ingress E-LSR copies the IP packet's IP TTL field into the MPLS header's TTL field.






32. 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






33. Ethernet MAC address that represents all devices on the LAN.






34. An Internet standard (RFC 1305) that defines the messages and modes used for IP hosts to synchronize their time-of-day clocks.






35. The portion of PPP focused on features that are unrelated to any specific Layer 3 protocol.






36. A switch feature that examines incoming frames - comparing the source IP and MAC addresses to the DHCP snooping binding database - filtering frames whose addresses are not listed in the database for the incoming interface.






37. 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.






38. 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.






39. 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.






40. An SPF calculation as a result of changes inside the same area as a router - for which the SPF run must examine the full LSDB.






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






42. Inverse ARP.






43. The combination of MPLS labels and links over which a packet will be forwarded over an MPLS network - from the point of ingress to the MPLS network to the point of egress.






44. A process on a computing device that issues requests for SNMP MIB variables from SNMP agents - receives and processes the MIB data - and accepts unsolicited Trap messages from SNMP agents.






45. The innermost MPLS header in an packet traversing an MPLS VPN - with the label value identifying the forwarding details for the egress PE's VRF associated with that VPN.






46. Protocol Independent Multicast dense-mode routing protocol.






47. The most recent standardized set of generic SNMP MIB variables - defined in RFC 1213 and updated in RFCs 2011 through 2013.






48. VLAN Trunking Protocol.






49. Type of Service byte.






50. Aka network layer reachability information.
