NEW QUESTION # 26
Which statements about the Alias and Redirect directives in Apache HTTPD's configuration file are true?
(Choose two.)

A. Alias can only reference files under DocumentRoot
B. Alias is not a valid configuration directive
C. Redirect works with regular expressions
D. Redirect is handled on the client side
E. Alias is handled on the server side

Answer: D,E

Explanation:
Explanation
The Alias and Redirect directives in Apache HTTPD's configuration file have different purposes and effects.
The Alias directive maps a URL path to a file system path, allowing the server to serve content that is not under the DocumentRoot. The Redirect directive instructs the client to make a new request with a different URL, which can be used to redirect requests to another server or location. The Redirect directive can use either a fixed URL or a regular expression to match and replace the original URL.
The difference between Alias and Redirect is that Alias is handled on the server side, meaning that the client does not see the file system path that the server uses to serve the content. The Redirect directive is handled on the client side, meaning that the client sees the new URL that the server sends back as a response. The client then makes a new request with the new URL, which may or may not be handled by the same server.
Therefore, the correct statements are C and D. Statement A is false because Alias can reference files outside of the DocumentRoot. Statement B is false because RedirectMatch is the directive that works with regular expressions, not Redirect. Statement E is false because Alias is a valid configuration directive.

NEW QUESTION # 27
In a PAM configuration file, which of the following is true about the required control flag?

A. If the module returns failure, no more modules of the same type will be invoked
B. The module is not critical and whether it returns success or failure is not important
C. The success of the module is needed for the module-type facility to succeed. If it returns a failure, control is returned to the calling application
D. The success of the module is needed for the module-type facility to succeed. However, all remaining modules of the same type will be invoked
E. If the module returns success, no more modules of the same type will be invoked

Answer: D

Explanation:
Explanation
The required control flag means that the PAM module is essential for the authentication process. If the module fails, the whole authentication fails. However, unlike the requisite control flag, the required control flag does not stop the execution of the remaining modules of the same type. This allows the user to receive feedback from all the modules, such as password expiration warnings or account lockout messages.

E. Add unix password sync = yes to smb.conf

Answer: E

Explanation:
Explanation
This option enables Samba to synchronize the UNIX password with the SMB password when the encrypted SMB password in the passdb is changed using smbpasswd. This means that the user only needs to change their password once, and both the UNIX and SMB passwords will be updated. Samba will use the passwd program specified by the passwd program option to change the UNIX password. Samba will also follow the passwd chat option to communicate with the passwd program. The other options are either invalid or irrelevant for this question. References: 1, 2, 3
