A telecommunications company implements branch versioning for their organization. The default version is the published version that portal users see…

The Protected access level is the correct and most secure setting for the default version in a production enterprise environment. This configuration allows all portal users to view the data, fulfilling its role as the published version. Critically, it restricts direct editing and the ability to post changes to only the version owner (typically a data administrator) and the geodatabase administrator. This prevents general editors from modifying the authoritative default version directly, thereby ensuring data integrity. It enforces a controlled workflow where edits from named versions are reviewed and then formally posted by an authorized user, which is a standard best practice.

A. Public: This setting would allow any user with editor permissions to modify the default version directly, bypassing controlled review workflows and risking the integrity of the published data.

C. Private: This setting would restrict viewing access to only the version owner and administrator, which contradicts the requirement that the version is visible to all portal users.

1. Esri ArcGIS Pro Documentation, "Version access" section in "Manage branch versions": This document defines the three access levels. For Protected, it states, "Any user can view the named version, but only the owner or the geodatabase administrator can edit the version and post changes to it." This confirms that Protected allows viewing while restricting edits to authorized roles, safeguarding the default version.

2. Esri ArcGIS Pro Documentation, "Reconcile and post edits to a branch version": This page clarifies the permissions needed for the post operation. It specifies, "To post, the portal account must also have access to edit the default version." This technical requirement supports the choice of Protected, as it centralizes the post operation with the owner/administrator who has edit rights, thus creating a controlled update process.

3. Esri ArcGIS Pro Documentation, "Share branch versioned data": This document outlines the standard workflow, describing the default version as the published representation of the data. It emphasizes that edits occur in named versions, which are then integrated back into default. A Protected default version is the mechanism that enforces this separation and control.
