Sitecore XM Cloud Developer Online Practice Questions

Explanation:
XM Cloud Components provide a low-code or no-code solution for building components, allowing for the consumption of data from various sources without extensive coding. On the other hand, Headless SXA Components are designed for developers to code and consume data, typically from the same data sources, offering a more hands-on approach to component creation.
Reference: The distinction between XM Cloud Components and Headless SXA Components is outlined in the Sitecore XM Cloud documentation, which describes the capabilities and intended use cases for each type of component12.

Explanation:
The correct GraphQL mutation to create a new item in Sitecore XM Cloud is createItem. This mutation allows developers to specify the necessary details such as the item’s name, template ID, parent ID, language, and fields to create a new content item within the Sitecore content tree.
Reference: The usage of the createItem mutation is documented in the Sitecore XM Cloud Developer’s Guide, which provides examples and explanations for authoring operations, including item creation1. Additionally, the Sitecore Stack Exchange provides insights into the available mutations for item management, confirming the use of createItem for creating new items2.

Explanation:
XM Cloud includes a modern technology stack that supports various frameworks and libraries for development. React is part of this stack, as it is commonly used in conjunction with Sitecore’s headless services and JSS (JavaScript Services) for building dynamic user interfaces.
Reference: The Sitecore XM Cloud documentation mentions the use of modern frameworks and libraries, including React, as part of its technology stack1. This aligns with the industry’s move towards more flexible and modular front-end development practices.

Explanation:
In Sitecore XM Cloud, if an administrator-level user cannot see the Layouts or Templates nodes in the content tree, it is likely because the “Hidden items” option is not selected in the Content Editor’s View tab. These nodes are typically marked as hidden to streamline the interface for users.
Reference: This solution is consistent with common practices in Sitecore content management, as indicated by community discussions and troubleshooting guides that address similar issues with hidden items in the content tree1.

Explanation:
The query to the Experience Edge GraphQL schema is designed to retrieve the layout information for a specific URL, which in this case is the root path (“/”) of a site named “experienceedge”. This allows developers to access the Layout Service JSON for the item, which is essential for rendering the page in a headless setup.
Reference: The Sitecore XM Cloud documentation describes the Experience Edge schema as a read-only GraphQL schema that supports common front-end use cases for headless Sitecore development, including querying an item’s layout by site and route path1.
