To enable read-write access to a dataset named DS1 via the XMLA endpoint, which setting must be modified first?

• A. the DS1 settings
• B. the WS1 settings
• C. the C1 settings
• D. the Tenant1 settings

Answer: (C)

Enabling read-write access through the XMLA endpoint starts from the highest level that controls whether the endpoint is even available. The C1 settings determine whether the XMLA endpoint is exposed across the namespace. If that top-level switch isn’t enabled, you can’t use XMLA for any dataset, no matter what its own settings say. Once the C1 setting is turned on, you can then configure read-write access for the specific dataset (DS1) within its workspace.

Choosing the dataset’s own settings wouldn’t turn on the endpoint itself, and workspace or tenant settings alone can’t unlock access if the global exposure isn’t enabled at the top level.
