Final answer:
The statement is False as Azure services in public preview can be managed by using various tools, not just the Azure CLI. Users can choose from the Azure portal, PowerShell, ARM templates, and more.
Step-by-step explanation:
The statement that Azure services in public preview can be managed only by using the Azure CLI is False. Azure offers various tools to manage its services, including the Azure portal, PowerShell, ARM templates, and the Azure CLI, among others. While Azure CLI is a powerful tool that can be used to manage Azure services, it is not the only method available, even for services that are in public preview.
Users have the flexibility to choose their preferred management tool based on their needs and expertise. It is important to consult Azure's documentation to understand the available management options for each service, as some preview features might be limited to certain tools, but this does not mean that the CLI is always the only option.
