When configuring an SMTP server for sending alert notifications via email in NDB, the two security options available are SSL and TLS. These protocols encrypt the email communication between NDB and the SMTP server, ensuring the confidentiality and integrity of alert notifications. NDB supports both options to accommodate different SMTP server configurations, with TLS being the more modern standard and SSL as a legacy option.
Other options are not applicable:
* B. S/MIME: This is used for email content encryption, not SMTP server configuration.
* C. DKIM: This is a domain authentication method, not a security protocol for SMTP.
Thus, the verified answers are A and D, reflecting NDB's SMTP security features.
