Once a production data load is completed in Communications Cloud, Salesforce's public data-migration and go-live readiness recommendations emphasize two mandatory activities: (1) remediation of failed records, and (2) validation of loaded data. These activities ensure that production contains a complete, accurate, and trusted data set before the system is opened to business users.

Option B -- Analyze and resolve any errors and re-load failed records

Even if a full-data migration completed successfully in a Full Copy sandbox, the production environment may still produce new failures due to data differences, unexpected validation rules, org-specific automation, or sequence dependencies. Salesforce migration best practices require analyzing the error logs generated by Data Loader, Bulk API, or middleware, correcting failed data, and performing targeted reloads. No migration is considered complete until every failed record has been addressed. This is a standard post-migration requirement in Communications Cloud given the volume and interdependencies between Accounts, Subscriptions, Service Accounts, Billing Accounts, Premises, Assets, Orders, and Fulfillment objects.

Option D -- Validate volumes and spot-check correctness

After the load finishes, the consultant must validate that record counts in production exactly match expected totals from source systems, including number of Accounts, Billing Accounts, Service Accounts, Subscriptions, Premises, and Assets. Salesforce also recommends targeted spot checks---opening individual customer records, ensuring relationships are correct, asset hierarchies are intact, and subscription data is consistent. This ensures data integrity before cutover and user access.

Incorrect options:

A -- Salesforce does not provide a data load report via support case; all logs come from the tools used during migration.

C -- You cannot assume ''all errors were resolved earlier.'' Every production load must be validated, and new issues frequently occur during the final cutover.

Therefore, the correct post-production-load actions are B and D.
