allowed to modify other pages in the site. What should you do first?
A.
Modify the site permissions.
B.
Edit the properties of the page.
C.
Stop the inheritance of permissions.
D.
Change the default Permission Levels.
Explanation:
About permission inheritance
Permissions on securable objects within a site are inherited from the parent object by default. You
can break inheritance and use fine-grained permissions — unique permissions on the list or library,
folder, or item or document level — to gain more control of the actions users can take on your site.
Stopping inheriting permissions copies the groups, users, and permission levels from the parent
object to the child object, and then breaks the inheritance. When permission inheritance is broken,
all permissions are explicit and any changes to parent object do not affect the child object. If you
restore inherited permissions, the child object will inherit its users, groups, and permission levels
from the parent again, and you will lose any users, groups, or permission levels that were unique to
the child object.
For ease of management, use permission inheritance wherever possible.
