When importing configurations specific to different sites into the same sandbox, the XML files that should be imported using site-specific Merchant Tools rather than through the Administration section are: B. Site Jobs - These files relate to scheduled jobs configured at the site level, containing settings and parameters specific to operations within individual sites. D. Promotions - These involve marketing and promotional settings that are typically specific to individual sites, affecting how discounts and special offers are applied and managed within that site's context. Importing these using the site-specific Merchant Tools ensures that configurations apply correctly and are managed in the context of the intended site, maintaining consistency and specificity in site operations.
