Suggested Answer:
Box 1: Premium -
Credential passthrough requires an Azure Databricks Premium Plan.
Incorrect Answers:
Support for Azure Data Lake Storage credential passthrough on standard clusters is in Public Preview.
Standard clusters with credential passthrough are supported on Databricks Runtime 5.5 and above and are limited to a single user.
Node: Azure Databricks supports three cluster modes: Standard, High Concurrency, and Single Node.
Box 2: Azure Data Lake Storage Gen1 Credential Passthrough
You can authenticate automatically to Azure Data Lake Storage Gen1 and Azure Data Lake Storage Gen2 from Azure Databricks clusters using the same Azure
Active Directory (Azure AD) identity that you use to log into Azure Databricks. When you enable your cluster for Azure Data Lake Storage credential passthrough, commands that you run on that cluster can read and write data in Azure Data Lake Storage without requiring you to configure service principal credentials for access to storage.

this will be standard cluster not premium. For credential passthrough you only need a azure databricks premium plan but not premium cluster.

i agree with the statement, cluster mode options are standard, high concurrency and single node. Thus, it make sense the choose "STANDARD" in the first box. Azure Databricks premium plan is needed to enable the passthrough feature. Reference: https://docs.microsoft.com/en-us/azure/databricks/security/credential-passthrough/adls-passthrough

Credential passthrough requires an Azure Databricks Premium Plan. See Upgrade or Downgrade an Azure Databricks Workspace for details on upgrading a standard plan to a premium plan https://docs.microsoft.com/en-gb/azure/databricks/security/credential-passthrough/adls-passthrough

Given explanation is correct: But as mentioned Azure Databricks supports three cluster modes: Standard, High Concurrency, and Single Node. There is no premium cluster mode, thus we need to go with standard
