Answers

1.	A. The DACL is the part of the security descriptor that is used to grant or deny specific users and groups access to the object. The SACL is used to determine which events are to be audited for specific users or groups. An access token contains the information regarding a logged-on user. The Security ID (SID) is used to uniquely identify objects in Active Directory.
2.	Place Accounts in Global groups. Nest your Global groups. Place Global groups in a Universal group. Assign Permissions to Domain Local groups. Put the Universal group in the Domain Local group. Follow the AG(G)UDLP method, but the placement of the Universal group in the Domain Local group should be last. By doing this task last, you prevent anyone from accessing the resources until they have been completely secured.
3.	C. When a share is created by default, the Everyone group is granted Full Control through the share.
4.	C. When a share is created by default, the Everyone group is granted Full Control through the share.
5.	B. Rather than making a user such as a help desk technician a member of the Administrators or Domain Administrators group, you can use delegation to grant the user or group control over an object or an entire Active Directory container, thus minimizing the number of users or groups who require membership in the administrative groups.
6.	A. EFS is the technology that should be used to secure the data on disk. NTFS will not prevent access to the files and folders if the disk is physically obtained by someone else. IPSec and SSL are used to encrypt data over the network, not on disk.
7.	B, C, D, E, F. The only permission that you should not assign to the Accountants group is Full Control because it includes the ability to change permissions and take ownership, which is not required in the scenario presented in the question.
8.	A, D. By default, an administrator and the creator/owner of the file would have the Full Control permission, which includes the Change Permissions special permission.
9.	B, C, D, E, F. You will have the Modify permission across the network. Full Control is not granted at the folder level; therefore, it will never propagate through the share.
10.	B, C, D, E, F. By default, the Everyone group is granted the Read permission on a share. The scenario states that the Employees group is granted the Change permission on the share. When combining Share and NTFS permissions, the most restrictive is what is effective. Administrators have, by default, the Full Control NTFS permission on all folders. When combined with the Change permission on the share, Change is the only permission granted to the Administrators group when accessing files and folders through the share.
