Comprehensive and Detailed 150 to 250 words of Explanation From Platform Sharing and Visibility Architect/Course Guide/topics:

The decisive requirement is that temporary deal access must expire automatically at a known future date. Salesforce sharing mechanisms such as manual or Apex-created shares can grant the temporary access, but a standard share entry does not carry an automatic expiration date. A Scheduled Apex job can therefore implement the lifecycle requirement by running after the specified fiscal-year date and removing only the temporary shares that were created for this collaboration program. Apex sharing by itself describes how access could be granted but not how it expires, while a sharing rule is population-based and is poorly suited to temporary per-deal collaboration with individual expiration. A production design should mark the temporary grants in a reliable way so the scheduled process removes only those shares and leaves ownership, hierarchy, teams, and unrelated sharing intact. Study Guide reference: Access to Records - temporary record sharing, Apex/manual shares, scheduled revocation, share lifecycle, and least-privilege collaboration.
