Looker Certified Explorer Practice Quiz — 20 Free Sample Questions
A lot of people who use Looker every day still fail the Certified Explorer exam — usually because they've never had to think precisely about why a dashboard filter isn't updating all tiles, or what the difference is between a dimension and a measure at the field definition level. The Looker Certified Explorer exam has approximately 50 multiple-choice questions and requires around 80% to pass. It tests whether you actually understand how Looker works — not just whether you can click around it. This practice quiz covers the real exam domains: navigating Explores, dimensions vs measures, creating Looks and dashboards, filter types, table calculations, scheduling, alerts, merged results, LookML field concepts, and permissions. The questions that trip people up most are the filter interaction ones and the content-sharing ones.
In Looker, which field type returns aggregated values such as sums, counts, or averages?
About the Looker Certified Explorer
The Looker Certified Explorer certification is a Google credential for data analysts and BI professionals who use Looker as consumers and builders of data content. The exam consists of approximately 50 multiple-choice questions with a passing score of around 80%, administered online through Google's certification portal. Core exam domains include: navigating Explores and understanding how they are structured, building and saving Looks, creating and configuring dashboards, applying filters at the dashboard, tile, and Explore levels (and understanding how they interact), using table calculations and pivots, scheduling deliveries and setting up alerts, merging results from multiple Explores, understanding LookML field types at a conceptual level (dimensions, measures, dimension groups, derived tables), managing content in folders and controlling sharing permissions. The Explorer exam does not require LookML development skills — that is covered by the Looker LookML Developer certification. The most common failures on the Explorer exam involve filter precedence, the difference between Alerts and Schedules, and content permissions and folder structure.
Frequently Asked Questions
What is the difference between the Looker Explorer and LookML Developer certifications?
The Explorer certification validates skills for data consumers and analysts who build Looks, dashboards, and reports using Looker's interface. The LookML Developer certification tests the ability to write and maintain LookML data models, define Explores, and build the data layer that Explorer users consume.
How long is the Looker Certified Explorer credential valid?
Google certifications typically expire after 2 years. Check Google's certification portal for the current recertification policy and any recent changes.
Is hands-on Looker experience required to pass the Explorer exam?
Strongly recommended. The exam is scenario-based and requires understanding how Looker behaves in practice — particularly around filter interactions, dashboard publishing, and content sharing. Candidates without hands-on access consistently struggle with these questions.
