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.

3. TCP and UDP Port 161






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

7. Command used to disable HTTP Server






8. Protects against repeating of secure sessions






9. Two FIN bits or one RST bit






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






11. 0x33 or 51






12. Four TCP/UDP Small Server commands recommended to disable






13. Layer 3






14. These ACLs filter by network or host IP address and only filter on source






15. Router threat that refers to willful attempts to cause such disruptions by overwhelming the targeted system with improperly formatted traffic






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






17. Release Number






18. No Known Vulnerability






19. Command used to disable NTP on an interface






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






21. Uses server and host keys to authenticate systems






22. When one network protocol called the payload protocol is encapsulated within a different delivery network - or provide a secure path through an untrusted network






23. Technology
