Solving Email Delivery Issues in a Public Cloud Environment

A.

If users are unable to send emails, the cloud engineer should troubleshoot the issue by following a logical approach. The FIRST step that the cloud engineer should take is to confirm the email server configuration.

Option A: Confirm the email server configuration and reinstall the email server software. Confirming the email server configuration is essential to ensure that all settings are properly configured. The email server should be set up to communicate with the destination email servers. The cloud engineer should check the network connectivity and firewall settings to ensure that the email server is not blocked from sending emails. If the configuration settings are incorrect, the engineer can reinstall the email server software to set up the email server with the correct settings.

Option B: Validate TLS certificates on the destination email gateway. TLS (Transport Layer Security) certificates are used to encrypt emails in transit to ensure that the emails are secure. However, if the email server is unable to send emails, validating the TLS certificates on the destination email gateway may not be the appropriate first step. This option should be considered only after verifying that the email server is correctly configured.

Option C: Confirm email encryption service. Email encryption is an additional layer of security that can be used to protect sensitive information in emails. However, if users are unable to send emails, confirming the email encryption service may not be the appropriate first step. This option should be considered only after verifying that the email server is correctly configured.

Option D: Consult the cloud vendor's anti-spam policy. Anti-spam policies are designed to prevent spam emails from being sent to other email accounts. If the email server is unable to send emails, checking the anti-spam policy of the cloud vendor may not be the appropriate first step. This option should be considered only after verifying that the email server is correctly configured.

In conclusion, option A is the FIRST step that the cloud engineer should take to resolve the issue of users being unable to send emails. Once the email server configuration has been confirmed, the engineer can proceed with the other options to resolve the issue if necessary.
