質問 41
A Delta Live Table pipeline includes two datasets defined using STREAMING LIVE TABLE.
Three datasets are defined against Delta Lake table sources using LIVE TABLE . The table is configured to
run in Development mode using the Triggered Pipeline Mode.
Assuming previously unprocessed data exists and all definitions are valid, what is the expected outcome after
clicking Start to update the pipeline?

  • A. All datasets will be updated continuously and the pipeline will not shut down. The compute resources
    will persist with the pipeline
  • B. All datasets will be updated once and the pipeline will shut down. The compute resources will be
    terminated
  • C. All datasets will be updated at set intervals until the pipeline is shut down. The compute resources will
    be deployed for the update and terminated when the pipeline is stopped
  • D. All datasets will be updated at set intervals until the pipeline is shut down. The compute resources will
    persist after the pipeline is stopped to allow for additional testing
  • E. All datasets will be updated once and the pipeline will shut down. The compute resources will persist to
    allow for additional testing

正解: E

 

質問 42
Projecting a multi-dimensional dataset onto which vector has the greatest variance?

  • A. first principal component
  • B. not enough information given to answer
  • C. second principal component
  • D. second eigenvector
  • E. first eigenvector

正解: A

解説:
Explanation
The method based on principal component analysis (PCA) evaluates the features according to the projection of
the largest eigenvector of the correlation matrix on the initial dimensions, the method based on Fisher’s linear
discriminant analysis evaluates. Them according to the magnitude of the components of the discriminant
vector.
The first principal component corresponds to the greatest variance in the data, by definition. If we project the
data onto the first principal component line, the data is more spread out (higher variance) than if projected onto
any other line, including other principal components.

 

質問 43
A data engineering team needs to query a Delta table to extract rows that all meet the same condi-tion.
However, the team has noticed that the query is running slowly. The team has already tuned the size of the
data files. Upon investigating, the team has concluded that the rows meeting the condition are sparsely located
throughout each of the data files.
Based on the scenario, which of the following optimization techniques could speed up the query?

  • A. Bin-packing
  • B. Z-Ordering
  • C. Write as a Parquet file
  • D. Tuning the file size
  • E. Data skipping

正解: B

 

質問 44
A data analyst has provided a data engineering team with the following Spark SQL query:
1.SELECT district,
2.avg(sales)
3.FROM store_sales_20220101
4.GROUP BY district;
The data analyst would like the data engineering team to run this query every day. The date at the end of the
table name (20220101) should automatically be replaced with the current date each time the query is run.
Which of the following approaches could be used by the data engineering team to efficiently auto-mate this
process?

  • A. They could replace the string-formatted date in the table with a timestamp-formatted date
  • B. They could manually replace the date within the table name with the current day’s date
  • C. They could pass the table into PySpark and develop a robustly tested module on the existing query
  • D. They could wrap the query using PySpark and use Python’s string variable system to automatically
    update the table name
  • E. They could request that the data analyst rewrites the query to be run less frequently

正解: D

 

質問 45
A data engineer has developed a code block to perform a streaming read on a data source. The code block is
below:
1. (spark
2. .read
3. .schema(schema)
4. .format(“cloudFiles”)
5. .option(“cloudFiles.format”, “json”)
6. .load(dataSource)
7. )
The code block is returning an error.
Which of the following changes should be made to the code block to configure the block to successfully
perform a streaming read?

  • A. The .read line should be replaced with .readStream
  • B. The .format(“cloudFiles”) line should be replaced with .format(“stream”)
  • C. A new .stream line should be added after the spark line
  • D. A new .stream line should be added after the .read line
  • E. A new .stream line should be added after the .load(dataSource) line

正解: A
