Correct Answer: ABCWhen updating sales territories and Account owners, two key factors to consider are the impact on sharing recalculations and the risk of lock errors. The data update will cause sharing recalculations, which can be resource-intensive and should therefore be completed during off-peak hours to minimize disruption. Additionally, the team can defer sharing calculations to decrease the risk of lock errors during the data update, ensuring a smoother process. There is no need to change the organization-wide default to Public, as the update can be performed with default set to Private. Also, Salesforce Platform can handle more than 200 accounts at a time, so that statement is not accurate.
