About Question enthuware.jwpv6.2.1198 :

[johnlamb]

From https://docs.oracle.com/cd/E19798-01/82 ... index.html

it states:

"The auth-method subelement configures the authentication mechanism for the web application. The element content must be either NONE, BASIC, DIGEST, FORM, or CLIENT-CERT. "

So shouldn't the question state "select 3 options"?

[admin]

As per section 14.4 (Point 18) of Servlet 3.1 specification:

18. login-config Element
The login-config is used to configure the authentication method that should be used, the realm name that should be used for this application, and the attributes that are needed by the form login mechanism. The sub-element authmethod configures the authentication mechanism for the Web application. The element content must be either BASIC, DIGEST, FORM, CLIENT-CERT, or a vendor-specific authentication scheme.

Since there is a little bit of discrepancy in the two resources, it is better to go with the specification.

HTH,
