220-1102 Question #541: Real Exam Question with Answer & Explanation

Question

When a user attempts to open an email using a company-issued smartphone, the user receives a message stating the email is encrypted and cannot be opened. The user forwards the email to a personal account and receives the same message. The user then contacts the IT department for assistance. The technician instructs the user to contact the sender to exchange information in order to decode the message. Which of the following will the user receive from the sender?

Options

• AKeys
• BToken
• CPassword
• DRoot CA

Explanation

An encrypted email cannot be opened without the necessary cryptographic information. To decode the message, the sender must provide the appropriate keys.

Common mistakes.

• B. A token is typically used for authentication or authorization, not directly for decrypting email content.
• C. While some encrypted communications might use a shared password, in standard email encryption, specific cryptographic keys are exchanged or used, not just a simple password for the email content itself.
• D. A Root CA (Certificate Authority) is part of the trust chain for verifying digital certificates, but it is not what is exchanged between users to decrypt a specific email message.
