To implement a specific cache period for Page Designer pages in SFRA:

• Option Ainvolves creating a new Page.js controller in the client’s cartridge, where the existing Page-Show route can be modified to include a custom caching logic. This ensures that the specific caching requirements for Page Designer pages are met without altering the base functionality for other pages.
• Option Dcalls for extending the existing cache.js module in the client’s cartridge to include a function specifically for Page Designer caching. This allows for reusing the existing caching logic while adding enhancements specific to the Page Designer pages, thus maintaining efficiency and clarity in the codebase.

Both options provide a clean, maintainable approach to customizing caching for specific requirements in SFRA, avoiding disruptions in other areas of the site functionality.

To resolve the issue of incorrect page versions being served across different devices, changing the URL structure to include device-specific parameters can be highly effective. By adding parameters such as 'desktop' or 'mobile' to the URLs:

• The caching mechanism can differentiate between the content for different device types, thus caching and serving the correct version of the page according to the device type specified in the URL.
• This method allows for maintaining existing caching strategies linked to promotions and ensures that SEO is not adversely affected since the content remains the same per device type but is merely served through different URLs.

This approach addresses the core issue without requiring disabling of caching or reengineering existing promotional structures, hence preserving site performance and user experience.

When facing build failures that are not reproducible in developers' environments, a common and effective first step is to clean up the build server workspace (Answer A). This action clears any residual files, settings, or data that might be influencing the build process and causing discrepancies between local and server builds. By resetting the workspace to a clean state, it helps ensure that the build process is starting from a consistent base, potentially resolving issues caused by stale data or corrupted build artifacts. This step often resolves hidden configuration or environment-specific issues that are not immediately apparent in the code or module versions.

Reducing the basket lifetime is a strategic approach to minimizing the impact of disabling a promotional coupon. This action will cause baskets that may still contain the now-disabled coupon to expire sooner, thereby reducing the potential volume of calls to the Call Center from customers inquiring about the coupon. This method also avoids the drastic measure of clearing all existing baskets or restarting the production instance, which could disrupt user experience and lead to further customer dissatisfaction.
