Which objects may have a queue?

In Salesforce, queues are a way to prioritize, distribute, and assign records to groups of users. Queues can hold records of specific standard or custom objects, and they allow for better management of incoming work items needing attention.

Among the options provided, the correct answer is that cases and custom objects can indeed have queues. Cases are particularly significant in the context of Service Cloud as they directly relate to customer service and support processes, and allowing queues for cases facilitates efficient workload management for support teams. Custom objects can also have queues, enabling organizations to manage records that aren't covered by standard Salesforce object capabilities.

While accounts and leads can be important objects within CRM for various business processes, they do not support the queuing function in the same way that cases and custom objects do. This distinction is key in understanding how Salesforce structures its data management system for optimal workflow processes. By leveraging queues, organizations can enhance their operational efficiency, ensuring that records are attended to promptly by the right users.
