Questions # 11:

The daily_forecast Explore used by the sales team needs to be cached for 24 hours. All other Explores usedby the sales team need to be cached for one hour.

What is a scalable way to configure this caching logic?

Options:

A.

Define two datagroups for the model. Apply persist_with at the model level with the datagroup for 1-hour caching, and apply persist_with to daily_forecast with the datagroup for 24-hour caching.


B.

Define max_cache_age on daily_forecast Explores of 24 hours. Define max_cache_age on all other Explores for one hour.


C.

Define two datagroups for the model. Create a persistent derived table (PDT) forthe daily_forecast Explore, and apply datagroup_trigger to it using the datagroup for 24-hour caching.


D.

Define for the model one datagroup that caches for 1 hour. Create a persistent derived table (PDT) for the daily_forecast Explore, and apply sql_trigger_value to it selecting the current date.


Questions # 12:

A LookML developer creates a new model and a test dashboard from the model. The developer shares the link to the new dashboard with users, but the users report that all they see is the “Model Not Found” error.

Questions # 13:

A LookML developer creates an Explore that joins two views. The base view has information about users’interactions with the support team. The joined view contains data about the users. The support team using this Explore feels overwhelmed by the amount of data this Explore shows them and decides to just look at open tickets.

What should the developer add to the Explore in the model to achieve these requirements?

Options:

A.

A filtered measure


B.

The hidden parameter


C.

The sql_always_where parameter


D.

A relationship definition

Questions # 15:

A developer needs to model out LookML to convert existing reports into Looker. The existing reports are:

Report 1: A report with order and order_items data, which finds the order with the largest total value of the order_item prices.

Report 2: A report with order and order_items data, which finds the order with the largest total number of products ordered.

Report 3: A report with data on every product, whether or not it has been ordered.

Each database table used is updated in real time as orders are made.

How should the developer construct an Explore using the order_items view as the base view?

Options:

A.

Create one persistent derived table to calculate Report 1, create one persistent derived table to calculate Report 2, and join in the products view with a full_outer join.


B.

Create one persistent derived table to calculate Reports 1 and 2, and join in the products view with a full_outer join.


C.

Create one ephemeral derived table to calculate Report 1, create one ephemeral derived table to calculate Report 2, andjoin in the products view with a left_outer join.


D.

Create one ephemeral derived table to calculate Reports 1 and 2, and join in the products view with a full_outer join.
