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 Cisco-proprietary messaging protocol used to negotiate the dynamic creation of PortChannels (EtherChannels) and to choose which ports can be placed into an EtherChannel.






2. Pulse code modulation.






3. 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






4. Defined in IEEE 802.1AD - defines a messaging protocol used to negotiate the dynamic creation of PortChannels (EtherChannels) and to choose which ports can be placed into an EtherChannel.






5. An 802.11 frame that access points or stations in ad hoc networks send periodically so that wireless stations can discover the presence of a wireless LAN and coordinate use of certain protocols - such as power-save mode.






6. 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






7. Peak information rate.






8. A reserved value for the BGP COMMUNITY path attribute that implies that the route should not be advertised outside the local AS.






9. In MPLS - a term used to define a label that an LSR learned from a neighboring LSR.






10. Allows the router to act as an inline IPS - doing deep packet inspection.






11. Data-link connection identifier.






12. The 32-bit number used to represent an OSPF router.






13. VLAN Trunking Protocol.






14. A multicast routing protocol that operates in dense mode and depends on the OSPF unicast routing protocol to perform its multicast functions.






15. The MD5-encoded password defined by the enable secret command.






16. A router that is allowed to receive a packet from an OSPF router and then forward the packet to another OSPF router.






17. 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






18. 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.






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






20. Router ID.






21. Expedited Forwarding.






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






23. A BGP path attribute that lists the next-hop IP address used to reach an NLRI.






24. Permanent virtual circuit.






25. Jargon referring to the minimum value to which adaptive shaping will lower the shaping rate.






26. 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






27. A Cisco IOS queuing tool most notable for its automatic classification of packets into separate per-flow queues.






28. 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.






29. An STP timer that dictates how long a switch should wait when it ceases to hear Hellos.






30. Assured Forwarding. A set of DiffServ PHBs that defines 12 DSCP values - with four queuing classes and three drop probabilities within each queuing class.






31. 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.






32. A numeric value between 0 and 32 (inclusive) that defines the number of beginning bits in an IP address for which all IP addresses in the same group have the same value. Alternative: The number of binary 1s beginning a subnet mask - written as a deci






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






34. Ethernet feature in which a NIC or Ethernet port can only transmit or receive at the same instant in time - but not both. Half duplex is required when a possibility of collisions exists.






35. Maximum transmission unit.






36. Cisco-proprietary STP feature in which a switch port monitors for STP BPDUs of any kind - err-disabling the port upon receipt of any BPDU.






37. An early T1 framing standard.






38. The original standardized set of generic SNMP MIB variables - defined in RFC 1158.






39. Used by a policer to classify packets relative to the traffic contract. These packets are considered to be above the traffic contract in all cases.






40. Neighbor Advertisement.






41. Measured Round-Trip Time.






42. An integer setting for EIGRP and IGRP. Any FS route whose metric is less than this variance multiplier times the successor's metric is added to the routing table - within the restrictions of the maximum-paths command.






43. Defined in RFC 1293 - this protocol allows a Frame Relay-attached device to react to a received LMI "PVC up" message by announcing its Layer 3 addresses to the device on the other end of the PVC.






44. A problem that occurs when an AS does not run BGP on all routers - with synchronization disabled. The routers running BGP may believe they have working routes to reach a prefix - and forward packets to internal routers that do not run BGP and do not






45. 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.






46. 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.






47. Cisco-proprietary VLAN trunking protocol.






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






49. A term referring generically to a server that performs many AAA functions. It also refers to the software product Cisco Secure Access Control Server.






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