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 type of OSPF packet used to discover neighbors - check for parameter agreement - and monitor the health of another router.






2. A route that is created to represent one or more smaller component routes - typically in an effort to reduce the size of routing and topology tables.






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






4. 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.






5. A method of collecting traffic received on a switch port or a VLAN and sending it to specific destination ports on the same switch.






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






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






8. 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.






9. With EIGRP - a route that is not a successor route - but that meets the feasibility condition; can be used when the successor route fails - without causing loops.






10. The process of taking the IP and TCP headers of a packet - compressing them - and then uncompressing them on the receiving router.






11. An EIGRP router's reaction to an input event - leading to the use of a feasible successor or going active on a route.






12. Dynamic ARP Inspection.






13. Inside telcos' original TDM hierarchy - the smallest unit of transmission at 64 kbps.






14. Variable-length subnet masking.






15. Dynamic Multipoint VPN.






16. The mandatory contention-based 802.11 access protocol that is also referred to as CSMA/CA.






17. 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.






18. Aka Rapid Per-VLAN Spanning Tree Plus.






19. Context-Based Access Control.






20. Cell Loss Priority.






21. A group of devices on one or more LANs that are configured (using management software) so that they can communicate as if they were attached to the same wire - when - in fact - they are located on a number of different LAN segments. Because VLANs are






22. 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






23. In the context of SNMP - the Set command is sent by an SNMP manager - to an agent - requesting that the agent set a single identified variable to the stated value. The main purpose is to allow remote configuration and remote operation - such as shutt






24. A component of the IOS IP SLA feature. An IP SLA responder is a router configured to respond to a particular IP SLA message initiated by another router - allowing the routers to work together to provide performance information including UDP jitter an






25. A NAT term describing an IP address representing a host that resides inside the enterprise network - with the address being used in packets inside the enterprise network.






26. Defined in IEEE 802.1d - a protocol used on LAN bridges and switches to dynamically define a logical network topology that allows all devices to be reached - but prevents the formation of loops.






27. Neighbor Discovery Protocol.






28. 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.






29. A method of providing dynamically configured spoke-to-spoke VPN connectivity in a hub-and-spoke network that significantly reduces configuration required on the spoke routers compared to traditional IPsec VPN environments.






30. In IPv6 - an address used in the Neighbor Discovery (ND) process. The format for these addresses is FF02::1:FF00:0000/104 - and each IPv6 host must join the corresponding group for each of its unicast and anycast addresses.






31. The term to describe a router that is neither the DR nor the BDR on a subnet that elects a DR and BDR.






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






33. An OSPF external route for which internal OSPF cost is not added to the cost of the route as it was redistributed into OSPF.






34. Per-VLAN Spanning Tree Plus.






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






36. 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.






37. Common Spanning Tree.






38. Temporal Key Integrity Protocol.






39. Jargon used to refer to the second of two buckets in the dual token bucket model; its size is Be.






40. The same thing as TCP code bits. See TCP code bits.






41. 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.






42. With private VLANs - a secondary VLAN in which the ports can send and receive frames only with promiscuous ports in the primary VLAN.






43. The process of successive neighboring routers exchanging LSAs such that all routers have an identical LSDB for each area to which they are attached.






44. An EIGRP message that informs neighbors about routing information. Update messages require an Ack.






45. Hot Standby Router Protocol.






46. 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






47. The process by which neighboring OSPF routers examine their Hello messages and elect the DR. The decision is based on priority (highest) - or RID (highest) if priority is a tie.






48. When a PIM-SM router switches from RPT to SPT - it sends a PIM-SM Prune message for the source and the group with the RP bit set to its upstream router on the shared tree. RFC 2362 uses the notation PIM-SM (S - G) RP-bit Prune for this message.






49. Maximum transmission unit.






50. Jargon referring to a policer action through which - instead of discarding an out-of-contract packet - the policer marks a different IPP or DSCP value - allowing the packet to continue on its way - but making the packet more likely to be discarded la
