220-1102 Question 567
Single answerClearing cacheA user reports that a company intranet site displays an outdated logo and old page content in Microsoft Edge on a Windows 11 laptop, even though the web team confirms the site was updated this morning. Other users can already see the new content. The technician verifies the laptop has internet access and can open other websites normally. Which action should the technician take FIRST to resolve the issue?
- A
Clear the browser's cached images and files for the affected site, then reload the page
- B
Flush the computer's DNS cache from an elevated command prompt
- C
Disable all browser add-ons and restart the browser
- D
Reset TCP/IP settings and reboot the laptop
Show answer and explanation
Correct answer: A
Explanation
The best first step is to clear the browser cache, specifically cached images and files, because the problem is limited to one user's browser showing outdated content while the site is otherwise reachable and updated for other users. In real-world support, technicians should start with the least invasive fix that matches the symptom. Browser caches are designed to improve performance by storing local copies of web resources, but they can sometimes continue serving outdated versions until the cache is cleared or refreshed. Microsoft and other browser vendors document clearing cached images/files as a standard step when websites display old content or do not load recent changes correctly. DNS cache flushing is useful for name resolution changes, and TCP/IP reset is for broader network issues, but neither is the most appropriate first action here.
- A. Correct.
Correct. When only one user is seeing outdated web page content while others already see the update, the most likely cause is stale browser cache. Clearing cached images and files forces the browser to download current page elements from the web server instead of reusing locally stored copies. This is the most direct and least disruptive first step.
- B. Incorrect.
Incorrect. Flushing the DNS cache can help when a hostname resolves to the wrong IP address or after DNS record changes, but DNS issues typically prevent reaching the correct site or send the user to the wrong server. In this scenario, the user reaches the site successfully and only sees old page content, which points more strongly to browser cache rather than DNS.
- C. Incorrect.
Incorrect. Add-ons can interfere with web page behavior, block scripts, or modify page rendering, so this is a plausible troubleshooting step. However, the symptom of seeing an older logo and stale content after a confirmed site update is more consistent with cached web objects than with an extension problem. Clearing cache is the better first action.
- D. Incorrect.
Incorrect. Resetting TCP/IP is a much broader network troubleshooting step used for persistent connectivity problems. The user already has internet access and can open the site, so there is no evidence of a TCP/IP stack issue. This option is unnecessarily disruptive and does not specifically address stale web content.
