https://learn.microsoft.com/en-us/power-bi/enterprise/directlake-overview#fallback-behavior The DirectLakeBehavior property can be configured by using Tabular Object Model (TOM) or Tabular Model Scripting Language (TMSL). The following example specifies all queries use Direct Lake mode only: C# Copy // Disable fallback to DirectQuery mode. // database.Model.DirectLakeBehavior = DirectLakeBehavior.DirectLakeOnly = 1; database.Model.SaveChanges();

Click on Semantic model. In the Properties pane, choose the Direct Lake behavior for your custom Direct Lake semantic model: Automatic: This is the default behavior. It allows Direct Lake with fallback to DirectQuery mode if data can’t be efficiently loaded into memory. Direct Lake only: This option ensures no fallback to DirectQuery mode https://powerbi.microsoft.com/en-au/blog/leveraging-pure-direct-lake-mode-for-maximum-query-performance/

In Tabular Editor version 3, it is possible to change the Default Mode to Direct Lake and it will be the right answer. Now I am confused with this question as TE version 2.5 does not allow the Default Mode of Direct Lake, so the only option is the Direct Lake Behavior.

The correct option to ensure queries use Direct Lake mode in Tabular Editor is: D. From Model, configure the Direct Lake Behavior option. Here's why the other options are incorrect: A. Default Mode: This option doesn't exist specifically for Direct Lake mode. It might be related to a different setting within the model. B. Partitions: Partitions are used to manage data refresh in large models, not to define the overall query mode. C. Storage Location: This option specifies where the model metadata is stored, not the data retrieval method.

IMHO, D, Because: Direct Lake models include the DirectLakeBehavior property, which has three options: ... **DirectLakeOnly** - Specifies all queries use Direct Lake mode only. Fallback to DirectQuery mode is disabled. If data can't be loaded into memory, an error is returned. Use this setting to determine if DAX queries fail to load data into memory, forcing an error to be returned. ... The DirectLakeBehavior property can be configured by using Tabular Object Model (TOM) or Tabular Model Scripting Language (TMSL).
