Snowflake SnowPro Advanced: Data Engineer Certification Exam Sample Questions (Q237-Q242):

NEW QUESTION # 237
A company extracts approximately 1 TB of data every day from data sources such as SAP HANA, Microsoft SQL Server, MongoDB, Apache Kafka, and Amazon DynamoDB. Some of the data sources have undefined data schemas or data schemas that change.
A data engineer must implement a solution that can detect the schema for these data sources.
The solution must extract, transform, and load the data to an Amazon S3 bucket. The company has a service level agreement (SLA) to load the data into the S3 bucket within 15 minutes of data creation.
Which solution will meet these requirements with the LEAST operational overhead?

A. Create a PySpark program in AWS Lambda to extract, transform, and load the data into the S3 bucket.
B. Create a stored procedure in Amazon Redshift to detect the schema and to extract, transform, and load the data into a Redshift Spectrum table. Access the table from Amazon S3.
C. Use Amazon EMR to detect the schema and to extract, transform, and load the data into the S3 bucket. Create a pipeline in Apache Spark.
D. Use AWS Glue to detect the schema and to extract, transform, and load the data into the S3 bucket. Create a pipeline in Apache Spark.

Answer: D

NEW QUESTION # 238
As Data Engineer, you have requirement to Load set of New Product Files containing Product rele-vant information into the Snowflake internal tables, Later you analyzed that some of the Source files are already loaded in one of the historical batch & for that you have prechecked Metadata col-umn LAST_MODIFIED date for a staged data file & found out that LAST_MODIFIED date is older than 64 days for few files and the initial set of data was loaded into the table more than 64 days earlier, Which one is the best approach to Load Source data files with expired load metadata along with set of files whose metadata might be available to avoid data duplication?

A. To load files whose metadata has expired, set the LOAD_UNCERTAIN_FILES copy option to true.
B. Since the initial set of data for the table (i.e. the first batch after the table was created) was loaded, we can simply use the COPY INTO command to load all the product files with the known load status irrespective of their column LAST_MODIFIED date values.
C. Set the FORCE option to load all files, ignoring load metadata if it exists.
D. The COPY command cannot definitively determine whether a file has been loaded al-ready if the LAST_MODIFIED date is older than 64 days and the initial set of data was loaded into the table more than 64 days earlier (and if the file was loaded into the table, that also occurred more than 64 days earlier). In this case, to prevent accidental reload, the command skips the product files by default.

Answer: A

Explanation:
Explanation
To load files whose metadata has expired, set the LOAD_UNCERTAIN_FILES copy option to true. The copy option references load metadata, if available, to avoid data duplication, but also at-tempts to load files with expired load metadata.
Alternatively, set the FORCE option to load all files, ignoring load metadata if it exists. Note that this option reloads files, potentially duplicating data in a table.
Please refer the Example as mentioned in the link below:

NEW QUESTION # 239
A company has an application that uses an Amazon API Gateway REST API and an AWS Lambda function to retrieve data from an Amazon DynamoDB instance. Users recently reported intermittent high latency in the application's response times. A data engineer finds that the Lambda function experiences frequent throttling when the company's other Lambda functions experience increased invocations.
The company wants to ensure the API's Lambda function operate without being affected by other Lambda functions.
Which solution will meet this requirement MOST cost-effectively?

A. Increase the Lambda function timeout and allocated memory.
B. Increase the number of read capacity unit (RCU) in DynamoDB.
C. Configure reserved concurrency for the Lambda function.
D. Configure provisioned concurrency for the Lambda function.

Answer: C

Explanation:
Reserved concurrency ensures that a specific Lambda function has a set number of concurrent executions that cannot be throttled due to other Lambda functions consuming shared concurrency limits. By configuring reserved concurrency, the API's Lambda function will always have the necessary resources to execute without being affected by other functions, thereby preventing throttling and ensuring consistent performance.

NEW QUESTION # 240
A data engineer uses Amazon Kinesis Data Streams to ingest and process records that contain user behavior data from an application every day.
The data engineer notices that the data stream is experiencing throttling because hot shards receive much more data than other shards in the data stream.
How should the data engineer resolve the throttling issue?

A. Limit the number of records that are sent each second by the producer to match the capacity of the stream.
B. Decrease the size of the records that the producer sends to match the capacity of the stream.
C. Use a random partition key to distribute the ingested records.
D. Increase the number of shards in the data stream. Distribute the records across the shards.

Answer: D

Explanation:
Amazon Kinesis Data Streams distribute data across multiple shards, with each shard having its own capacity for read and write operations. Throttling occurs when one or more shards, referred to as "hot shards," receive significantly more data than they can handle. To resolve this, increasing the number of shards in the data stream and redistributing the records across the shards is the appropriate solution. This approach ensures that the workload is spread more evenly, thereby preventing throttling on individual shards.

NEW QUESTION # 241
A data engineer is using an AWS Glue ETL job to remove outdated customer records from a table that contains customer account information. The data engineer is using the following SQL command to remove customers that exist in a table named monthly_accounts_update table from the customer accounts table:
MERGE INTO accounts t USING monthly_accounts_update s
ON t.customer = s.customer
WHEN MATCHED
THEN DELETE
What will happen when the data engineer runs the SQL command?

A. Only customer records that are present in both tables will be retained in the customer accounts table.
B. All customer records that exist in both the customer accounts table and the monthly_accounts_update table will be deleted from the accounts table.
C. The monthly_accounts_update table will be deleted.
D. No records will be deleted because the command syntax is not valid in AWS Glue.

Answer: B

Explanation:
That MERGE statement deletes every row in accounts where the customer value matches a row in monthly_accounts_update. All overlapping customer records will be removed from the accounts table.
