A FortiWeb administrator is deciding between using SAML SSO or HTML authentication.

SAML SSO is the correct choice when the goal is to reduce repeated credential prompts across multiple services. SAML uses a federated identity model, where users authenticate through an identity provider and then use assertions to access service providers without repeatedly entering credentials. This is exactly the value of single sign-on. HTML form authentication is more local and application-specific; it can authenticate users to a protected site, but it does not provide the same cross-service identity federation. Option B overstates SAML as a policy-blocking mechanism. Option C may be simpler but does not meet the SSO requirement. Option D incorrectly describes HTML form authentication as token-based remote-service access.
