220-1102 Question #156: Real Exam Question with Answer & Explanation

Question

After returning from vacation, a user is unable to connect to the network at the corporate office. Windows allows the user to log in; however, no internal or external websites are accessible when running a browser. The user's expected network shares are unreachable, and all websites attempted return the message, `Hmm, we can't reach this page.` Which of the following is the MOST likely cause of this issue?

Options

• AThe user's password expired while on vacation.
• BThe user clicked on a malicious email.
• CThe user connected to a captive portal while traveling.
• DThe user enabled airplane mode.

Explanation

A complete inability to access any network resources (internal or external) while logged into Windows, accompanied by "Hmm, we can't reach this page" errors, is a strong indicator of an activated airplane mode.

Common mistakes.

• A. An expired password would prevent the user from logging into network resources or Windows itself if configured for network authentication, but it wouldn't result in a complete loss of all network connectivity with a "cannot reach page" error.
• B. Clicking on a malicious email might lead to various security or performance issues, but it wouldn't typically cause an immediate and complete loss of all network connectivity without other observable symptoms.
• C. Connecting to a captive portal while traveling is irrelevant once the user is back at the corporate office, as the corporate network environment would be entirely different and would not retain captive portal settings or restrictions.
