A company plans to use Amazon Q Business and must protect the security and privacy of its data. Which combination of actions will satisfy these requirements? (Choose two.)

To protect data security and privacy in Amazon Q Business, enabling AWS Key Management Service (KMS) keys for the Enterprise index ensures that all data at rest is encrypted with customer-managed keys, providing strong control over encryption. Configuring AWS Identity and Access Management (IAM) for authentication is crucial for controlling who can access Amazon Q Business and what actions they can perform, enforcing the principle of least privilege. Establishing cross-account access to the Amazon Q index is not inherently a security measure; it's an architectural choice that requires careful security configuration. Amazon Inspector is a vulnerability management service, not an authentication mechanism. Allowing public access to the Amazon Q index would compromise data privacy and security.
