Which of the following is a benefit of Sitecore's rendering and layout system?

The benefit of Sitecore's rendering and layout system is enhanced performance and simplified updates. This system allows developers to create reusable components that can be used across different pages and layouts. By leveraging this modular architecture, changes can be made more efficiently since updates to a component reflect universally wherever that component is used, reducing the need for redundant edits.

Additionally, the rendering and layout system supports performance optimization by allowing for the integration of caching strategies. This means that once content and layouts are rendered, they can be cached for quicker retrieval, significantly improving page load times and the overall user experience.

In contrast, options highlighting increased content duplication, a lack of modularity, and less control over content distribution do not align with the objectives of the rendering and layout system, which aims for efficiency, reusability, and better performance management.
