QuestionQ4

(Official exam topics not publicly listed on Adobe’s certification page)

A developer needs to restrict a template’s use to a specific content path.

Which property should be configured?

Explanation

cq:allowedPaths restricts a template’s availability by matching the content-page path against its configured allowed path pattern. cq:allowedTemplates is used to specify templates permitted beneath a content branch, rather than to constrain where one template itself may be used.

QuestionQ5

(Official exam topics not publicly listed on Adobe’s certification page)

An AEM Developer is responsible for creating a French version of an e-commerce site for several French-speaking African countries, including Chad, Ivory Coast, and Senegal.

What are the correct steps for implementing the sites with localized content?

Explanation

AEM Multi-Site Manager should be limited to content in one language. A primary French site can serve as the source for French live copies for Chad, Ivory Coast, and Senegal, while allowing country-specific localization where needed. Adobe recommends using a primary French site to create French versions for country sites.
