220-1102 Question 565
Single answerPop-up blockerA user reports that a web-based training portal opens the login page correctly, but when they click Start Course, nothing happens. You verify the site is trusted and learn the portal launches the course player in a new browser window. Other websites work normally, and there are no network connectivity issues. What is the BEST action to restore access while maintaining security?
- A
Disable the browser's pop-up blocker for all websites
- B
Add the training portal's site to the browser's allowed pop-up exceptions list
- C
Clear the browser cache and cookies, then retry the site
- D
Disable the local firewall because it may be blocking the new window
Show answer and explanation
Correct answer: B
Explanation
The best answer is to allow pop-ups for the specific trusted training portal rather than disabling protections broadly. In real support scenarios, many legitimate business applications, training systems, and financial sites still use secondary windows for authentication steps, reports, or content players. Modern browsers typically include configurable pop-up blocking with per-site exceptions, which is the preferred troubleshooting method because it restores the required functionality while minimizing exposure to unwanted or malicious pop-ups from other sites. This aligns with standard browser security best practices published in vendor documentation for Chrome, Edge, and Firefox, which support allowing pop-ups for specific sites instead of turning the feature off globally.
- A. Incorrect.
This is incorrect because disabling the pop-up blocker globally reduces security and user protection across all sites. In this scenario, the issue is limited to one trusted training portal that needs to open a new window, so a site-specific exception is the more appropriate and least disruptive fix.
- B. Correct.
This is correct because the site uses a new browser window to launch the course player, and a pop-up blocker commonly prevents that behavior. Creating an exception for the specific trusted portal restores functionality while preserving pop-up protection for other websites. This is the recommended best practice when a legitimate business site requires pop-ups.
- C. Incorrect.
This is incorrect because cache and cookies can cause login or session issues, but they do not directly address a blocked pop-up window. Someone might choose this option because it is a common browser troubleshooting step, but the scenario specifically points to a new window failing to open.
- D. Incorrect.
This is incorrect because a local firewall does not normally block standard browser pop-up windows generated by a website. This option reflects a common misconception between network/application filtering and browser-based content controls. The firewall is not the most likely cause given that the site loads and only the new window fails to appear.
