MCTS: Protepcting Network Traffic With IPsec

Instructions:
  • Answer 42 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. IPsec provides ______ in the form of data origin authentication - data integrity - and anti-replay protection.






2. Like IPsec Policies - ______ evaluate network traffic and then block - allow - or negotiate security for messages based on the criteria you establish.






3. IP ______ contain a set of one or more IP filters that capture IP traffic for an IPsec Policy.






4. Note that when matching a source or destination address - the most ______ IPsec filter always takes precedence.






5. Each policy rule - in turn - is associated with one IP ______ and one filter action.






6. You can use IPsec to encrypt network data so that the data is unreadable if captured in transit. This describes what?






7. Phase 1 negotiation is known as main mode negotiation - and Phase 2 is known as ______ negotiation.






8. The main advantage of using Connection Security Rules is that they are ______.






9. Possible filter actions for a rule include block - permit - or ______ security.






10. If you need to implement IPsec in a production environment in which Kerberos authentication is not available - you should use a ______ infrastructure to authenticate the IPsec peers.






11. You can assign only one IPsec Policy to a computer at a time. If you assign a second IPsec Policy to a computer - the first IPsec Policy ______.






12. Security for an SA is provided by the two IPsec protocols: ______ and ______.






13. ______ provides data encryption - data origin authentication - data integrity - and anti-replay protection for the ESP payload.






14. You can use IPsec to ensure that data is not altered in transit. This describes what?






15. Determines whether the traffic captured by an IP filter in a given policy rule is permitted - blocked - encrypted - or authenticated.






16. You can use an Isolation rule to configure "domain isolation." This simply means that you can use Connection Security Rules to block traffic from computers originating from outside the local ______.






17. If Group Policy assigns an IPsec Policy to a computer - the computer ______ IPsec Policy assigned in its Local Security Policy.






18. ______ by default attempt to negotiate only authentication services.






19. You should assign the ______ policy to intranet servers that require secure communications - such as a server that transmits highly sensitive data.






20. In Group Policy - three IPsec Policies are predefined. You can thus configure an IPsec Policy for a domain or an OU by assigning any one of the following predefined policies:






21. With IPsec ______ mode - an entire IP packet is protected and then encapsulated with an additional - unprotected IP header.






22. Every IPsec Policy rule have an IP filter list even if the ________________.






23. ______ provides data origin authentication - data integrity - and anti-replay protection for the entire IP packet.






24. IPsec by default operates in ______ mode - which is used to provide end-to-end security between computers.






25. You can configure IPsec to verify that each packet received is unique and not duplicated. This describes what?






26. Remember that ______ authentication is preferable in an AD environment. Outside of an AD environment - a certificate infrastructure is your best option.






27. You can assign an IPsec Policy either to an individual computer by using Local Security Policy or to a group of computers by using ______.






28. In Win Vista - Win 7 - Win Srvr 2008 and Win Srvr 2008 R2 - IPsec is enforced either by ______ or ______.






29. You configure Connection Security Rules for any one computer in the ______ console or the ______node in Server Manager.






30. You can configure IPsec to ensure that each packet you receive from a trusted party in fact originates from that party and is not spoofed. This describes what?






31. Transport mode is also used in most IPsec-based VPNs - for which the ______is used to tunnel the IPsec connection through the public network.






32. If you need encryption - use ______. If you just need to authenticate the data origin or verify data integrity - use ______.






33. You can use any of these three methods to authenticate the hosts communicating through IPsec:






34. You can summarize the steps for establishing an IPsec connection in the following way:






35. IPsec protects data between two IP addresses by providing the following services:






36. Every IPsec Policy is composed of one or more IPsec Policy ______ that determine when and how IP traffic should be protected.






37. To establish SAs dynamically between IPsec peers - the ______ protocol is used.






38. After two computers negotiate an IPsec connection - whether through IPsec Policies or Connection Security Rules - the data sent between those computers is secured in what is known as a ______.






39. You should assign the ______ policy to computers for which encryption is preferred but not required.






40. ______ by default attempt to negotiate both authentication and encryption services.






41. When you assign ______ policy to a computer through a GPO - that computer will never initiate a request to establish an IPsec communications channel with another computer.






42. To ensure successful and secure communication - IKE performs a ______ negotiation operation - each with its own SAs.
