Salesforce Admin Certification Practice Test

Restricting organization access in Salesforce primarily involves controlling how and when users can log into the system, which is effectively achieved through the use of IP address restrictions and login hours. By specifying a range of accepted IP addresses, you can ensure that only users connecting from designated locations can access the Salesforce org. This can be particularly useful for enhancing security in sensitive environments, as it prevents unauthorized access from unknown or untrusted networks.

Similarly, setting login hours allows administrators to define specific time frames during which users are permitted to log in. This feature can be utilized to enforce company policies regarding work hours and to prevent access to the system during off-hours, further safeguarding sensitive organizational data.

In contrast, other options such as setting login codes, managing organization charts, or creating user groups do not directly contribute to the same level of access control that IP address restrictions and login hour settings provide. While these may assist with user management and organization structure, they do not directly affect who can log in and when, making option B the most effective method for restricting access in Salesforce.
