Snowflake SnowPro Advanced: Data Engineer Certification Exam Sample Questions (Q118-Q123):

NEW QUESTION # 118
A company stores a 100 MB dataset in an Amazon S3 bucket as an Apache Parquet file. A data engineer needs to profile the data before performing data preparation steps on the data. Which solution will meet this requirement in the MOST operationally efficient way?

Answer: C

Explanation:
AWS Glue DataBrew provides built-in data profiling specifically for exploring dataset structure, data types, distributions, missing values, and anomalies before preparation. For a 100 MB Parquet file in Amazon S3, creating a profile job is the most operationally efficient approach because it requires minimal setup and no custom infrastructure or query framework.


NEW QUESTION # 119
A data engineer notices slow query performance on a highly partitioned table that is in Amazon Athena. The table contains daily data for the previous 5 years, partitioned by date.
The data engineer wants to improve query performance and to automate partition management.
Which solution will meet these requirements?

Answer: D

Explanation:
Partition projection eliminates the need for frequent metadata lookups or explicit partition registration in the AWS Glue Data Catalog. By defining a date range in your table's properties (for example, projection.enabled=true, projection.order_date.type=DATE, projection.order_date.range=2020/01/01,NOW, and the appropriate format), Athena will calculate partitions on-the-fly. This both speeds up queries (avoiding catalog calls for thousands of partitions) and removes the need for any external partition-management jobs.


NEW QUESTION # 120
A company wants to migrate a data warehouse from Teradata to Amazon Redshift.
Which solution will meet this requirement with the LEAST operational effort?

Answer: D

Explanation:
This solution provides the least operational effort for migrating a data warehouse from Teradata to Amazon Redshift by using AWS services that are specifically designed for schema and data migration:
AWS Schema Conversion Tool (SCT) is used to convert and migrate the schema from Teradata to Amazon Redshift, handling schema differences automatically and reducing manual work.
AWS Database Migration Service (DMS) is then used to transfer the data from Teradata to Redshift, allowing for efficient data migration.


NEW QUESTION # 121
The following CREATE DATABASE command creates a clone of a database snowmy_db i.e.
Create database pods_db clone snowmy_db
before (statement => '7e5d0cb9-005e-94e6-b058-k8f5b37c5725');
What are possible reason of failing cloning operation for this database?

Answer: A,D


NEW QUESTION # 122
A company uses an Amazon Redshift cluster as a data warehouse that is shared across two departments. To comply with a security policy, each department must have unique access permissions.
Department A must have access to tables and views for Department A. Department B must have access to tables and views for Department B.
The company often runs SQL queries that use objects from both departments in one query.
Which solution will meet these requirements with the LEAST operational overhead?

Answer: A

Explanation:
By organizing each department's tables and views into its own schema (for example, dept_a and dept_b), you can grant usage and object privileges at the schema level. Department A's role gets USAGE on schema dept_a and the necessary SELECT rights there (and no rights on dept_b), and vice versa for Department B. Because both schemas live in the same database, analysts can still run cross-department queries by schema-qualifying objects, and you avoid the extra complexity of multiple databases or intricate IAM policies.
