What could be the issue?

A user started to work remotely. They are having an Issue logging in.

What could be the issue?
A . The login session has expired for this user.
B . They are signing in from a mobile device.
C . The time zone for the profile is outside of login hours.
D . The user Is not In the IP range for their profile.

Answer: D

Explanation:

IP ranges are settings that restrict login access to Salesforce from specific IP addresses. Administrators can set IP ranges at the org level or at the profile level. If a user tries to log in from an IP address that is outside the allowed range for their profile or their org, they will not be able to access Salesforce. Therefore, if a user started to work remotely and is having an issue logging in, it could be because they are not in the IP range for their profile or their org.
