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. Refers to addresses used on the organization's private network






2. This server is used for querying a host about its logged in users






3. These ACLs filter by network or host IP addresses andspecific protocol type or port numbers - filters by source and destination






4. Helps to mitigate problems that are caused by the introduction of malformed or spoofed IP source addresses into a network by discarding packets lacking a verifiable IP source address






5. An alternative for both standard and extended ACLs that allow you to refer to an ACL by a descriptive name instead of a number






6. What Local and Global refer to in NAT






7. Software that blocks packets from unreachable hosts - thus allowing only reachable external hosts to initiate connections to a host on an internal network






8. Tunnel Mode Protocol provides confidentiality - along with authentication and integrity protection with encryption






9. Privilege levels that can have passwords assigned to them






10. Cryptographic protocols that provide secure communications on the Internet for such thing as WWW - email - faxing - IM - and other data transfers






11. What Tunnel Mode is used for






12. Can discover vulnerabilities - network stats - and firewall discovery






13. Authentication Header (AH) and Encapsulated Security Payload (ESP)






14. Command used to disable HTTP Server






15. Geolocational positioning






16. Broadcast

20. Mode where only the payload of the IP packet is encrypted and/or authenticated






21. TCP and UDP Port 162






22. Time can be changed - Routing Table can be killed






23. Local and Remote






24. ESP - SSH - SSL/TLP






25. 0-99






26. 33400-34400






27. TCP only - used to filter inbound traffic while allowing return TCP sessions - can be spoofed by attackers and cannot be used with Active FTP






28. Refers to addresses used on the organization's private network






29. Command to disable CDP on a router






30. Lists interfaces - routing table - ARP table - physical and network addresses - time last booted

32. UDP Port 1701






33. 0x32 - or 50






34. Public IP address before translation






35. A suite of protocols for securing Internet Protocol communications by authenticating and/or encrypting each IP packet in a data stream






36. DENY IP 224.0.0.0 15.255.255.255 ANY






37. Public IP address after translation






38. The host can specify which route to take - which bypasses security






39. Proprietary - used by Cisco routers and switches use to identify each other on LAN and WAN segments






40. Privilege level that is restricted to basic level operations






41. Command to disable TCP small server on a router






42. Mode where the entire packet is encrypted and/or authenticated - requiring a new IP packet to be encapsulated






43. War dialing






44. Form of dynamic NAT that maps multiple unregistered IP addresses to a single registered IP address by using different ports; limited to ~64 -000 hosts






45. Major Version






46. Major Version - Minor Version - Release - Interim Build - Release Train Identifier






47. Cisco default tunneling protocol that uses multicast addressing without encryption and is designed to encapsulate a wide variety of network layer packets inside IP tunneling packets






48. Breaks LAN security perimeter extends LAN to Layer 2






49. Users - Host PC's - IP Addresses






50. Allows the source IP host to specify a route through the IP network
