Looker LookML Developer Practice Test 2025 - Free LookML Developer Practice Questions and Study Guide

The statement is true because the Content Validator in Looker is designed to help users identify issues that could arise from changes or inconsistencies in the LookML model. However, it is not intended to apply validation directly to objects like custom filters, custom fields, or table calculations created at the user interface level.

Custom filters and fields are user-generated elements that are not governed by core LookML code but are instead built on top of the existing model. Therefore, they operate outside the purview of the Content Validator, which is focused on LookML code quality and integrity, ensuring that the underlying structure and logic of the data model remain intact.

Similarly, table calculations are specific to the context of a data exploration session and do not affect the model itself. They are calculated on the fly when a report is run, which means they do not have a permanent representation in the LookML layer and, thus, are not subject to the validations that the Content Validator performs.

In summary, the Content Validator's limitations regarding the exclusion of user-defined elements underscore its primary function: maintaining the integrity and performance of the LookML codebase rather than validating or managing user-added components.
