This read-create TruthValue marks a download server entry as the default used when a new cpeConfigMgrEntry is created without explicitly specifying a cpeConfigMgrDwnldSrvrToUsed value, and only applies at configuration time, not runtime. An admin sets exactly one server entry to true to avoid ambiguity about which server new profiles will inherit by default. For example, an operator flags the primary download server as cpeCfgMgrDwnldSrvrDefault so any newly created manager profile automatically uses it unless told otherwise.
