IBM WebSphere Portal 8.0 Solution Development 認定 C9520-911 試験問題:

1. A software delivery executive, by the name of Fry, is developing a custom theme called Popplers. He has deployed the theme with six custom layouts (Lla, Zdb, Bdr, Amy, Pff and Hms) at dav:fstype1/themes/Popplers/layout-templates.
Over the past few days, he has been trying to scope three of these layouts (Lla, Zdb and Bdr) however, none of them are visible in the WebSphere Portal 8.0 Layout tab.

C) One cannot partially scope custom layouts in a theme. Just like the default Portal 8.0 theme, you must scope all defined custom layouts.
