Answer: Secondary access key
The question requires configuring permanent access to an Azure Files share from an Azure Machine Learning datastore. The secondary access key (Option A) is the correct choice because it provides long-term, persistent access without expiration, unlike SAS tokens which are temporary. Account SAS keys (Option C) and Service SAS keys (Option D) have expiration limits and require periodic renewal, making them unsuitable for permanent access. Anonymous access (Option B) is not supported for Azure Files, as authentication is always required. The community discussion supports this, with the highest upvoted comment (3 upvotes) explaining that access keys remain valid until manually regenerated, ensuring permanent access, while SAS tokens are short-lived.
