Snowflake SnowPro Advanced: Data Engineer Certification Exam DEA-C01 Prüfungsfragen mit Lösungen (Q140-Q145):

140. Frage
A company has an on-premises PostgreSQL database that contains customer data. The company wants to migrate the customer data to an Amazon Redshift data warehouse. The company has established a VPN connection between the on-premises database and AWS.
The on-premises database is continuously updated. The company must ensure that the data in Amazon Redshift is updated as quickly as possible.
Which solution will meet these requirements?

Antwort: D

Begründung:
AWS DMS can perform an initial full load of your on-premises PostgreSQL data into Redshift and then continuously capture and apply changes (CDC) over the VPN. This approach keeps your Redshift tables up to date with minimal latency and operational overhead.


141. Frage
A company needs to use Amazon Athena to analyze data that is in an Amazon S3 bucket. A data engineer needs to configure AWS Glue table partitions for year, month, and day. The data engineer needs to create the partitions every day to adjust to schema changes in the data.
Which solution will meet these requirements?

Antwort: C

Begründung:
Partition projection in AWS Glue lets Athena automatically calculate partitions based on table properties without explicitly creating them each day. This eliminates the need for crawlers or Lambda jobs, reduces operational overhead, and adapts to schema changes while supporting year, month, and day partitions efficiently.


142. Frage
A company uses Amazon Redshift to store order transactions from the current day. The company has an orders table that contains the previous order data. The company also has a staging table that contains new or updated order records.
The company needs to remove stale records from the orders table and insert the most recent data in the orders table from the staging table. Several downstream applications need the orders table to display up-to-date information.
Which solution will meet these requirements?

Antwort: B

Begründung:
An Amazon Redshift stored procedure can perform the delete-and-insert logic directly inside the warehouse in a single controlled operation. This is the most appropriate way to remove stale rows from the target table and load the latest records from the staging table while keeping the orders table current for downstream applications, without introducing unnecessary data movement or external processing.


143. Frage
A company uses an Amazon S3 bucket to integrate multiple data sources into a central data lake.
The company needs to perform multiple transformations and data cleaning processes on the data to make the data accessible to business partners.
The company needs a solution that will give multiple business partners the ability to run SQL queries on the central data lake during normal business hours.
Which solution will meet these requirements MOST cost-effectively?

Antwort: A

Begründung:
AWS Glue Flex Jobs provide discounted, off-hours batch ETL to transform S3 data, and Amazon Redshift Serverless offers on-demand SQL access during business hours without paying for idle clusters minimizing cost and operations.


144. Frage
A security company stores IoT data that is in JSON format in an Amazon S3 bucket. The data structure can change when the company upgrades the IoT devices. The company wants to create a data catalog that includes the IoT data. The company's analytics department will use the data catalog to index the data.
Which solution will meet these requirements MOST cost-effectively?

Antwort: D
