Field update and email alert are two types of automated actions that can be added as part of the approval process. Field update allows you to change the value of a field on a record when it is submitted, approved, rejected, or recalled. Email alert allows you to send an email to one or more recipients when a record is submitted, approved, rejected, or recalled.

Quick actions allow you to initiate expense reports from Salesforce to an external HR system. Approval processes allow you to review the expense reports by managers and directors.

IP address restrictions allow you to prevent users from accessing Salesforce from outside of their network. You can set IP address restrictions on the profile level or globally for the org. To enforce IP restrictions for API logins, you must select Enforce Login IP Ranges on Every Request in Session Settings.

Multi factor authentication (MFA) is a security feature that requires users to verify their identity using two or more factors when they log in to Salesforce. It can help prevent unauthorized access to Salesforce by adding an extra layer of protection beyond username and password. Enabling MFA can be done by administrators in the security settings or by users in their personal settings. Disabling TLS requirements for sessions, customizing organization wide defaults, or enabling caching and autocomplete on login page are not actions that would prevent unauthorized access to Salesforce; in fact, they may reduce security or have no effect on security at all.

To help sales reps prioritize and close more deals, the administrator should use Einstein Opportunity Scoring, which is a feature that assigns each opportunity a score from 1 to 99 based on how likely it is to be won. The score is calculated using historical data and machine learning models, and can help reps focus on the most promising opportunities and take actions to improve their chances of winning. Einstein Activity Capture, Einstein Search Personalization, and Einstein Lead Scoring are not related to opportunity management.
