CompTIA A+ Core 2 (220-1002) — Question 321

Joe, a user, cannot read encrypted email messages on a corporate smartphone, but he has been able to read them in the past. A technician restarts Joe's smartphone, but the issue remains. The technician deletes the corporate email account and has Joe re-add it, verifying all settings are correct. Despite these steps, the issue persists.
Which of the following is MOST likely causing the issue?

Answer options

• A. The certificate is expired.
• B. The TPM is bad.
• C. The phone is not encrypted.
• D. The incorrect mail server is selected in settings.

Correct answer: A

Explanation

The most likely cause is that the certificate is expired, as this would prevent Joe from decrypting the emails. The other options, such as a faulty TPM or incorrect mail server settings, are less likely to be the cause since the technician has verified the email account settings and restarting the phone typically resolves hardware-related issues.
