¿Qué variables NO son posible modificar después de crear la campaña? S ele cci on ar 2 las respuestas correctas

After a campaign is created in Mercado Ads, you cannot modify the segmentation (automatic or custom) or the destination URL. These are fundamental structural variables that the system uses for algorithm learning and traffic direction. Changing them would fundamentally alter the campaign's core strategy, requiring a new campaign to be created. In contrast, the budget, keywords, and creative are dynamic elements that can be adjusted during the campaign's lifecycle to optimize performance without needing to restart the entire campaign.
