In the deployment process, what must follow the deserialization of items?

After the deserialization of items in the deployment process, it is essential to undertake extra steps like publishing and index rebuild. This is because deserializing items adds or updates content items in Sitecore's content tree, but those changes are not immediately visible on the front end until the content is published.

Publishing makes the newly deserialized content available in the appropriate publishing target (usually the live website), ensuring that the updates are reflected to end-users. Additionally, rebuilding indexes is crucial as it ensures that any changes made to the content items are also searchable and visible in the Sitecore search interface. If these steps are skipped, the content may exist in your Sitecore instance but won’t be accessible or searchable, which undermines the purpose of the deployment.

The other options do not follow logically after deserialization. Installing Sitecore typically occurs before any content deployment, while copying assets from a solution is more related to project setup than the deployment workflow. Forwarding a case to Sitecore Support does not follow as a necessary step in the deployment process unless there is a specific issue that cannot be resolved through normal means.
