Q20. Two developers are working on adding a new view to a project. Once both developers have finished their work in the view, the changes will be pushed to production.
Where should the developers write the LookML for this view?

In the master branch, with both users writing to the branch

In one user’s personal branch, with both users writing to the branch

In a new shared branch created from the master branch

In each of their personal branches, with each user writing code separately

Q21. Users report that every time they change the filter on their Explore, the filters take a very long time to populate.
How can the developer improve the filtering experience with this Explore?

Limit the filter suggestions using the suggestions parameter.

Add an always_filter parameter to restrict the filter suggestions.

Use an access_filter parameter to automatically apply filters.

Add persistence to the base view of the Explore.

Q22. Users report that the main dashboard has been slow to show results.
Which two options should the developer evaluate to improve dashboard performance? (Choose two.)

Number of databases used by dashboard elements

Number of queries used by the dashboard

Ratio of visualizations to text tiles

Format used to deliver these reports

Amount of data rendered for each query

Q23. A user is seeing an error in the Explore that indicates the primary key defined for a one-million-row table is not unique.
How can the developer use SQL Runner to troubleshoot quickly?

Create a query that selects all the fields from the table, and sort by primary key.

Create a query that selects the primary key from the base view, and look for duplicates.

Create a query that counts how many occurrences of the primary key value are in the base view, and sort by count.

Create a query that concatenates two columns to create a compound primary key.

Q24. A retail company wants to limit who can see the financial information in their reports to executives and store managers. The LookML Developer creates a user attribute called leadership with the value “000” for executives and “999” for store managers. The developer creates three access grant objects and one dimension:

How should the developer ensure that only authorized users see the data in the Total Revenue dimension?

required_access_grants: [can_view_financial_data]

required_access_grants: [leadership]

required_access_grants: [“000″,”999”]

required_access_grants: [total_revenue]

Q25. A LookML developer has created a model with many Explores in it. Business users are having a difficult time locating the Explore they want in the long list displayed.
Which two actions can the LookML developer take to improve the user interface? (Choose two.)

Apply the hidden parameter with a value of yes to Explores that only exist to power specific Looks, dashboards, or suggestion menus.

Modify the business users’ roles so they do not have this model in their model set.

Combine the Explores into just a few Explores that each join to many views.

Apply the group_label parameter to organize the Explores under different headings.

Apply the fields parameter so that each Explore has fewer fields in it.

Q26. A developer wants to calculate the ratio of total sales from the orders view and total users from the users view.
Which two methods can be used to create a measure that meets these requirements? (Choose two.)

B)

C)

D)

E)

Option A

Option B

Option C

Option D

Option E

Q27. A developer defines the following measure in the order_items view:

The code must validate without errors.
Which action should the developer take?

Join order_items and inventory_items in a derived table.

Join order_items and inventory_items in the same Explore.

Copy the cost definition from inventory_items to the order_items view file.

Add the following to the order_items view file: include: “inventory_items,view.lkml”

Q28. After running the Content Validator, a developer can see the error “Unknown field”.
Which two changes could cause this issue? (Choose two.)

View name was changed from users to customers.

Field type was changed from number to string.

Model name was changed from e_commerce to reporting.

Explore label was changed from users to customers.

Field name was changed from id to user_id.

Q29. A LookML developer has a transactions view with several measures that each perform complex calculations involving multiple fields. The LookML developer creates an Explore based on the transactions view. The product team wants to perform further functions on these measures, such as SUM, AVG, MIN, MAX, and RANK. The team wants these further functions to be performed at different levels of detail: weekly, monthly, and yearly.
How can the LookML developer model these requirements and minimize the amount of code rewriting?

Add measures to the transactions view of type: number to apply the required functions.

Change the existing measures in the transactions view to dimensions, and add measures of the different required types.

Create a constant for each measure so it can be reused across other areas of the LookML project.

Create native derived tables using transactions as the explore_source.

Q30. A developer has the dimensions enrollment_month and graduation_month already defined in the view. Both were created as part of dimension_groups of type: time. The developer need to use these two dimensions in the sql_start and sql_end parameters of a dimension group of type: duration.
Which LookML should be used to calculate the number of month and years between enrollment month and graduation month?
A)

B)

C)

D)

Option A

Option B

Option C

Option D

Q31. A developer commits changes after adding LookML for a new measure. Upon pulling from production, the developer notices the following lines in the LookML:

Remove “<<<<<< HEAD”, “======”, and “>>>>>> branch ‘master'”

Remove “<<<<<< HEAD”, “======”, and everything following “======”

Remove everything between “<<<<<< HEAD” and “======”, and “>>>>>> branch ‘master'”

Remove everything between “<<<<<< HEAD” and “>>>>>> branch ‘master'”

Q32. A LookML developer is creating a new view with 20 dimensions in Development Mode using the Create View from Table functionality. Now users want the developer to add only four dimensions from this new view to an existing Explore.
What can the developer add to the Explore to limit the number of fields from the view that are accessible to the user in the Explore?

Set definition

Join condition

Fields parameter

Hidden parameter

Q33. Business users report that an ephemeral derived table tile on the dashboard is slow.
Information about the dashboard includes:
The dashboard filter is linked to the user attributes.
This tile usually takes approximately 5 minutes to complete running.
Which solution should be used to improve the dashboard load time?

Use a conditional WHERE clause for Development Mode.

Build a user attribute filter into the Explore.

Use index distribution_key or sort_key for this derived table.

Persist the derived table.

Q34. The developer has moved the orders Explore (shown below) from model_a to model_b, where both models are in the same project, and all users have access to both models.
Connection: “demo”
include: “.view”
explore: orders {}
What will happen after making this change?

Dashboard tiles and Looks will be automatically pointed to the orders Explore in model_b.

Dashboard tiles and Looks will redirect to the new database connection.

Dashboard tiles and Looks that rely on this Explore will be deleted.

Dashboard tiles and Looks that rely on this Explore will return an error.

Q35. A LookML developer has written the following persistent derived table. It references orders_rollup, another persistent derived table that also rebuilds with the same SQL trigger value.

Which change is needed to guarantee that user_facts will always rebuild with the latest data from orders_rollup?

Change the sql_trigger_value parameter of user_facts to select the current date plus one hour, so it triggers an hour after orders_rollup.

Change the orders_rollup view reference to ${orders_rollup.DERVIED_TABLE_NAME}

Change the sql_trigger_value parameter for both persistent derived tables to a datagroup_trigger parameter, and set them to use the same datagroup.

Change the orders_rollup view reference to the literal table name from the database’s scratch schema.
