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. Digital Signal Level 1.






2. Committed information rate.






3. A BGP path attribute that is communicated throughout a single AS to signify which route of multiple possible routes is the best route to be taken when leaving that AS. A larger value is considered to be better.






4. With Spanning Tree Protocol - the single port on each LAN segment from which the best Hello BPDU is forwarded.






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






6. A Cisco-proprietary STP implementation - created many years before IEEE 802.1s and 802.1w - that speeds convergence and allows for one STP instance for each VLAN.






7. 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.






8. A Cisco 12000 series router feature that combines the key features of LLQ and CQ to provide similar congestion-management features.






9. The Cisco IOS feature by which special short key sequences can be used to move the cursor inside the current command line to more easily change a command.






10. Extended Superframe.






11. Network Address Translation-Protocol Translation.






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






13. An STP timer that dictates the interval at which the Root switch generates and sends Hello BPDUs.






14. The actual number of packets in a queue at a particular time.






15. A single instance of STP that is applied to multiple VLANs - typically when using the 802.1Q trunking standard.






16. An 802.1d STP port state in which the port does not send or receive frames - except for listening for received Hello BPDUs.






17. With PIM on a multiaccess network - the PIM router with the highest IP address on the subnet. It is also the IGMPv1 Querier. The DR is responsible for the following tasks: - Sending PIM register and PIM join and prune messages toward the RP to infor






18. A routing protocol feature by which the routing update includes only routes that have changed - rather than include the entire set of routes.






19. 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.






20. A 3-bit field in an 802.1Q header used for marking frames.






21. Loss of Frame.






22. Network Layer Protocol ID is a field in the RFC 2427 header that is used as a Protocol Type field in order to identify the type of Layer 3 packet encapsulated inside a Frame Relay frame.






23. A process used in routers that are encrypting traffic to permit egress QoS actions to be taken on traffic that is being encrypted on that router. QoS pre-classification keeps a copy of each packet to be encrypted in memory long enough to take the app






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






25. 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






26. 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.






27. A tunneling protocol that can be used to encapsulate many different protocol types - including IPv4 - IPv6 - IPsec - and others - to transport them across a network.






28. In the context of SNMP - the GetNext command is sent by an SNMP manager - to an agent - requesting the value of a single MIB variable. The GetNext request identifies a variable for which the manager wants the variable name and value of the next MIB l






29. Defined in RFC 826 - a protocol used on LANs so that an IP host can discover the MAC address of another device that is using a particular IP address.






30. A calculation of the length of the AS_PATH PA - which includes 1 for each number in the AS_SEQ - 1 for an entire AS_SET segment - and possibly other considerations.






31. 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.






32. The speed at which the access link is clocked. This choice affects the price of the connection and many aspects of traffic shaping and policing - compression - quality of service - and other configuration options.






33. An enhanced version of WEP that is part of the 802.11i standard and has an automatic key-update mechanism that makes it much more secure than WEP. TKIP is not as strong as AES in terms of data protection.






34. Data Set Ready.






35. Similar to an appliance firewall - in that interfaces are placed into security zones. Traffic is allowed between interfaces in the same zone. You can apply policies to filter and control traffic between zones.






36. A BGP router that forwards iBGP-learned routes to other iBGP routers.






37. Controls the distribution of multicast traffic by checking the TTL values configured on the interfaces. It forwards the multicast packet only on those interfaces whose configured TTL value is less than or equal to the TTL value of the multicast packe






38. The command used to initialize a SPAN or RSPAN session on a Catalyst switch.






39. 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.






40. A state variable kept by a router for each known neighbor or potential neighbor.






41. Layer 2 payload compression.






42. In BGP - a configuration construct in which multiple neighbors' parameters can be configured as a group - thereby reducing the length of the configuration. Additionally - BGP performs routing policy logic against only one set of Updates for the entir






43. 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.






44. 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






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






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






47. Defined in RFC 1631 - a method of translating IP addresses in headers with the goal of allowing multiple hosts to share single public IP addresses - thereby reducing IPv4 public address depletion.






48. Slow Start Threshold.






49. Carrier sense multiple access with collision detection. A media-access mechanism where devices ready to transmit data first check the channel for a carrier. If no carrier is sensed for a specific period of time - a device can transmit. If two devices






50. A BGP router in an AS that uses route reflectors - but that is not aided by any RR server.
