Correct Answers: C, E and F 
RentMe wants to give access to a portal page with targeted promotions only to premium customers. These customers are all authenticated users. To provide access to the particular web page, you need to create a new web portal role, like Premium. Then you need to create a new Web Page Access Control Rule. A Web Page Access Control Rule has two settings: Grant Access and Restrict Read. 
The Grant Access rule allows a user (associated with the rule by the user’s web role) to publish content on a page and its child pages. 
The Restricted Read rule limits viewing of the page and its child pages to specific users. 
For premium customers, we need to use the Restricted Read option. After you create a Web Page Access rule by including a web page and selecting the Restricted Read option, you must link the rule with the Premium web role. 
You can do all these operations from Portal Management (Number 1). Under the Security section (Number 2), select the Web Roles (Number 3). Create and save a new web role Premium for authenticated users (Number 4). After the screen is updated, click on the Related tab (Number 5). In the new menu, select the Web Page Access Control Rules (Number 6). Then on a new screen, click on the "Add Existing Web Page” (Number 7). When you create a new record, you need to provide a rule name, website, and web page. Then select the Right (grant access levels) — Restrict Read and the scope — “All content.” After you save the record for this web role, you will see a new record in Rule Associate View with the Premium name (Number 8), a web page name (Number 9), the Right (Number 10), and the scope (Number 11). Now only the users with the Premium web role can access the Services web page and its child pages. 

All other options are incorrect.
