HOTSPOT
A company is upgrading to SharePoint Server 2013.
You plan to migrate an existing PHP eCommerce site to SharePoint Server 2013.
The ecommerce site has the following requirements:
Users must be able to browse all products available.
Users must be able to drill down on specific product attributes.
Product attributes must be stored as managed metadata.
You need to determine which components you should implement.
Which components are required? To answer, select the appropriate option from each list in the
answer area.
Answer: 
Explanation:
* Cross Site Publishing is required as metadata will be used as product attributes.
You can use cross-site publishing to create an Internet business site that contains a catalog that
shows products to customers, based on metadata. Users view pages that are created dynamically
based on navigation, and filter results based on additional refinements. The site may also show
content such as a company contact page, shipping and handling rates, and job openings. Content is
authored internally, and is made available to anonymous users outside the firewall.
You can use cross-site publishing to create a knowledge base that is available to internal and
external users in an extranet site. Content authors tag pages with metadata to categorize articles so
that users can search or browse for specific information, such as troubleshooting articles, support
issues, and service packs.
* Managed metadata service is required as product attributes must be stored as managed metadata.
* Search Web Parts is required as users must be able to browse (search) the products.
* Secure Store Service is not required as single-sign on is not required.
The Secure Store Service replaces the Microsoft Office SharePoint Server 2007 Single Sign On
feature. Secure Store Service is a shared service that provides storage and mapping of credentials
such as account names and passwords. It enables you to securely store data that provides
credentials required for connecting to external systems and associating those credentials to a
specific identity or group of identities.* Device Channels is not required as there is no requirement that the web pages should be rendered
in different devices (such as mobile phones, tablets).
A device channel is part of the SharePoint 2013 publishing infrastructure that enables you to render
certain site content, style your content, and even change images—while maintaining the same URL
across a pool of different devices.
