All Development-Lifecycle-and-Deployment-Architect Test Inside Salesforce Questions

 Using a Developer Edition org to stage changes to their Customer Community poses the following risks:

Developer Edition orgs have limited user counts and low data volume limits, which will make User Testing difficult, as the testing environment will not be representative of the production environment.

Developer Edition orgs cannot have sandboxes, which will make team development difficult, as the developers will not be able to work in isolated environments and test their changes before merging them.

Changes Sets cannot be used to deploy from Developer Edition to Production, which will make deployment more complex, as the developers will have to use other tools such as Ant Migration Tool or SFDX CLI to deploy their changes.

Change Sets are a manual way of deploying metadata components between orgs that are affiliated with the same production org. Change Sets cannot be automated, rolled back, or reused between production Salesforce orgs. Change Sets can be validated before deployment, and they can be used for orgs affiliated with the same production org.

 Executing all test classes in sandboxes can help identify and fix any errors or failures before deploying to production. Executing selected test classes in production can help reduce the deployment time and avoid running unnecessary tests.

To deploy custom metadata types to production using Metadata API, you need to include the CustomMetadata and CustomField data types. CustomMetadata represents the custom metadata type definition, and CustomField represents the custom metadata type fields. CustomMetadataType and CustomObject are not valid data types for custom metadata types
