Explanation
When troubleshooting a web application displaying outdated content, clearing the browser cache, performing a hard refresh, or using an incognito mode are effective solutions as they bypass or clear the cached data. These actions ensure the browser retrieves the latest version of the content from the server, resolving caching-related issues.
- A. Correct.
Clearing the browser's cache through the settings removes stored versions of web pages, ensuring the latest content is loaded.
- B. Incorrect.
Disabling JavaScript functionality is unnecessary and could cause other issues with website functionality.
- C. Correct.
Performing a hard refresh forces the browser to reload the page from the server, bypassing the cache.
- D. Incorrect.
Restarting the device does not clear the browser cache; caches are managed within the browser itself.
- E. Correct.
Using incognito or private browsing mode ensures no cached data is used, as the mode does not store cache or cookies.
