Which statement describes this implementation?

A) The customers table is implemented as a Type 0 table; all writes are append only with no changes to existing values.
B) The customers table is implemented as a Type 1 table; old values are overwritten by new values and no history is maintained.
C) The customers table is implemented as a Type 2 table; old values are maintained but marked as no longer current and new values are inserted.
D) The customers table is implemented as a Type 3 table; old values are maintained as a new column alongside the current value.
E) The customers table is implemented as a Type 2 table; old values are overwritten and new customers are appended.

2. The data architect has mandated that all tables in the Lakehouse should be configured as external (also known as "unmanaged") Delta Lake tables.
Which approach will ensure that this requirement is met?

A) When tables are created, make sure that the EXTERNAL keyword is used in the CREATE TABLE statement.
B) When a database is being created, make sure that the LOCATION keyword is used.
C) When the workspace is being configured, make sure that external cloud object storage has been mounted.
D) When configuring an external data warehouse for all table storage, leverage Databricks for all ELT.
E) When data is saved to a table, make sure that a full file path is specified alongside the Delta format.

3. The business intelligence team has a dashboard configured to track various summary metrics for retail stories. This includes total sales for the previous day alongside totals and averages for a variety of time periods. The fields required to populate this dashboard have the following schema:

For Demand forecasting, the Lakehouse contains a validated table of all itemized sales updated incrementally in near real-time. This table named products_per_order, includes the following fields:

Because reporting on long-term sales trends is less volatile, analysts using the new dashboard only require data to be refreshed once daily. Because the dashboard will be queried interactively by many users throughout a normal business day, it should return results quickly and reduce total compute associated with each materialization.
Which solution meets the expectations of the end users while controlling and limiting possible costs?

A) Use the Delta Cache to persists the products_per_order table in memory to quickly the dashboard with each query.
B) Configure a webhook to execute an incremental read against products_per_order each time the dashboard is refreshed.
C) Define a view against the products_per_order table and define the dashboard against this view.
D) Populate the dashboard by configuring a nightly batch job to save the required to quickly update the dashboard with each query.
E) Use Structure Streaming to configure a live dashboard against the products_per_order table within a Databricks notebook.

Assume that the fields customer_id and order_id serve as a composite key to uniquely identify each order.
If the upstream system is known to occasionally produce duplicate entries for a single order hours apart, which statement is correct?

A) Each write to the orders table will only contain unique records, but newly written records may have duplicates already present in the target table.
B) Each write to the orders table will only contain unique records; if existing records with the same key are present in the target table, these records will be overwritten.
C) Each write to the orders table will only contain unique records; if existing records with the same key are present in the target table, the operation will tail.
D) Each write to the orders table will only contain unique records, and only those records without duplicates in the target table will be written.
E) Each write to the orders table will run deduplication over the union of new and existing records, ensuring no duplicate records are present.

5. A table named user_ltv is being used to create a view that will be used by data analysts on various teams. Users in the workspace are configured into groups, which are used for setting up data access using ACLs.
The user_ltv table has the following schema:
email STRING, age INT, ltv INT
The following view definition is executed:

An analyst who is not a member of the auditing group executes the following query:
SELECT * FROM user_ltv_no_minors
Which statement describes the results returned by this query?

A) All age values less than 18 will be returned as null values all other columns will be returned with the values in user_ltv.
B) All columns will be displayed normally for those records that have an age greater than 17; records not meeting this condition will be omitted.
