NEW QUESTION # 13

Which query did the analyst execute in order to get this result?

Answer: C

NEW QUESTION # 14
Which of the following is an advantage of using a Delta Lake-based data lakehouse over common data lake solutions?

A. Open-source formats
B. Flexible schemas
C. Data deletion
D. Scalable storage
E. ACID transactions

Answer: E

Explanation:
A Delta Lake-based data lakehouse is a data platform architecture that combines the scalability and flexibility of a data lake with the reliability and performance of a data warehouse. One of the key advantages of using a Delta Lake-based data lakehouse over common data lake solutions is that it supports ACID transactions, which ensure data integrity and consistency. ACID transactions enable concurrent reads and writes, schema enforcement and evolution, data versioning and rollback, and data quality checks. These features are not available in traditional data lakes, which rely on file-based storage systems that do not support transactions. Reference:

NEW QUESTION # 15
Which of the following should data analysts consider when working with personally identifiable information (PII) data?

A. All of these considerations
B. Legal requirements for the area in which the analysis is being performed
C. Organization-specific best practices for Pll data
D. Legal requirements for the area in which the data was collected
E. None of these considerations

Answer: A

Explanation:
Data analysts should consider all of these factors when working with PII data, as they may affect the data security, privacy, compliance, and quality. PII data is any information that can be used to identify a specific individual, such as name, address, phone number, email, social security number, etc. PII data may be subject to different legal and ethical obligations depending on the context and location of the data collection and analysis. For example, some countries or regions may have stricter data protection laws than others, such as the General Data Protection Regulation (GDPR) in the European Union. Data analysts should also follow the organization-specific best practices for PII data, such as encryption, anonymization, masking, access control, auditing, etc. These best practices can help prevent data breaches, unauthorized access, misuse, or loss of PII data.

NEW QUESTION # 16
A data analyst runs the following command:
INSERT INTO stakeholders.suppliers TABLE stakeholders.new_suppliers;
What is the result of running this command?

A. The suppliers table now contains both the data it had before the command was run and the data from the new suppliers table, including any duplicate data.
B. The command fails because it is written incorrectly.
C. The suppliers table now contains only the data from the new suppliers table.
D. The suppliers table now contains the data from the new suppliers table, and the new suppliers table now contains the data from the suppliers table.
E. The suppliers table now contains both the data it had before the command was run and the data from the new suppliers table, and any duplicate data is deleted.

Answer: B

Explanation:
The command INSERT INTO stakeholders.suppliers TABLE stakeholders.new_suppliers is not a valid syntax for inserting data into a table in Databricks SQL. According to the documentation12, the correct syntax for inserting data into a table is either:
INSERT { OVERWRITE | INTO } [ TABLE ] table_name [ PARTITION clause ] [ ( column_name [, ...] ) | BY NAME ] query INSERT INTO [ TABLE ] table_name REPLACE WHERE predicate query The command in the question is missing the OVERWRITE or INTO keyword, and the query part that specifies the source of the data to be inserted. The TABLE keyword is optional and can be omitted. The PARTITION clause and the column list are also optional and depend on the table schema and the data source. Therefore, the command in the question will fail with a syntax error.

NEW QUESTION # 17
What describes the variance of a set of values?

A. Variance is a measure of how far an observed value is from the variable's maximum or minimum value.
B. Variance is a measure of how far a set of values is spread out from the sets central value.
C. Variance is a measure of how far a single observed value is from a set ot va IN
D. Variance is a measure of central tendency of a set of values.

Answer: B

Explanation:
Variance is a statistical measure that quantifies the dispersion or spread of a set of values around their mean (central value). It is calculated by taking the average of the squared differences between each value and the mean of the dataset. A higher variance indicates that the data points are more spread out from the mean, while a lower variance suggests that they are closer to the mean. This measure is fundamental in statistics to understand the degree of variability within a dataset.WikipediaWikipedia+1Investopedia+1
