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 basic form of traffic shaping that is applied to an interface or subinterface. By default - it shapes all traffic leaving the interface - but can be modified by using an access control list. The access list controls only what traffic is shaped; GTS






2. A route that is used for forwarding packets when the packet does not match any more specific routes in the IP routing table.






3. 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.






4. Structure of Management Information.






5. An alternative software loaded into a Cisco router - used for basic IP connectivity; most useful when Flash memory is broken and you need IP connectivity to copy a new IOS image into Flash memory.






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






7. A network/subnet over which two or more OSPF routers have become neighbors - thereby being able to forward packets from one router to another across that network.






8. VTP process that prevents the flow of broadcasts and unknown unicast Ethernet frames in a VLAN from being sent to switches that have no ports in that VLAN.






9. The single port on each nonroot switch upon which the best Hello BPDU is received.






10. A router feature used when a router sees an ARP request searching for an IP host's MAC - when the router believes the IP host could not be on that LAN because the host is in another subnet. If the router has a route to reach the subnet where the ARP-






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






12. The IEEE standardized protocol for VLAN trunking.






13. With OSPF - the encapsulation of OSPF messages inside IP - to a router with which no common subnet is shared - for the purpose of either mending partitioned areas or providing a connection from some remote area to the backbone area.






14. Smoothed Round-Trip Time.






15. Class-Based Marking.






16. 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.






17. An effort to reduce the query scope with EIGRP - using route summarization or EIGRP stub routers.






18. Backward Explicit Congestion Notification.






19. 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.






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






21. A 3-bit field in an MPLS header used for marking frames.






22. A DiffServ PHB that defines eight values that provide backward compatibility with IP Precedence.






23. A local Cisco-proprietary BGP setting that is not advertised to any peers. A larger value is considered to be better.






24. A predefined VC. A PVC can be equated to a leased line in concept.






25. With EIGRP - for a particular route - the case in which the RD is lower than the FD.






26. A wireless LAN that only includes wireless users and no access points. 802.11 data frames in an ad hoc network travel directly between wireless users.






27. The portion of PPP focused on supporting the CDP protocol.






28. 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.






29. 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.






30. 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.






31. Advanced Encryption Standard A superior encryption mechanism that is part of the 802.11i standard and has much stronger security than TKIP.






32. WRED compares this setting to the average queue depth to decide whether packets should be discarded. All packets are discarded if the average queue depth rises above this maximum threshold.






33. Refers to how a router views a BGP peer relationship - in which the peer is in the same AS.






34. Removing unwanted VLANs from a Layer 2 path.






35. Expedited Forwarding.






36. PIM-SM is a method of routing multicast packets that requires some intelligence in the network about the locations of receivers so that multicast traffic is not flooded into areas with no receivers. PIM Sparse Mode gets its name from the assumption t






37. A security standard that includes both TKIP and AES and was ratified by the Wi-Fi Alliance.






38. Network Based Application Recognition.






39. An NTP mode in which an NTP host does not adjust its clock - but in which it sends NTP messages to clients so that the clients can update their clocks based on the server's clock.






40. The RFC 1997 name for the reserved COMMUNITY path attribute known to Cisco IOS as LOCAL_AS. (See LOCAL_AS.)






41. Class Selector.






42. An IP variable that defines the largest size allowed in an IP packet - including the IP header. IP hosts must support an MTU of at least 576 bytes.






43. A Cisco IOS feature that performs deep packet inspection to classify packets based on application layer information.






44. Protocol Independent Multicast dense-mode routing protocol.






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






46. 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






47. The OSPF data structure that describes topology information.






48. A list of interspersed alphanumeric literals and metacharacters that are used to apply complex matching logic to alphanumeric strings. Often used for matching AS_PATHs in Cisco routers.






49. Defined in RFC 3748 - the protocol used by IEEE 802.1X for exchanging authentication information.






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