What is the primary objective of Data Lifecycle Management (DLM)?

  1. To ensure data integrity and accuracy

  2. To optimize data storage and retrieval

  3. To protect data from unauthorized access

  4. To comply with regulatory and legal requirements


Correct Option: B
Explanation:

DLM aims to manage data throughout its lifecycle to ensure efficient storage, retrieval, and disposal, while minimizing costs and risks.

Which phase of the data lifecycle involves the initial creation and capture of data?

  1. Storage

  2. Processing

  3. Acquisition

  4. Retention


Correct Option: C
Explanation:

Acquisition is the first phase of the data lifecycle, where data is initially created or captured from various sources.

What is the purpose of data retention policies?

  1. To ensure data availability for legal or regulatory purposes

  2. To optimize data storage and reduce costs

  3. To protect data from unauthorized access

  4. To improve data quality and accuracy


Correct Option: A
Explanation:

Data retention policies are implemented to comply with legal and regulatory requirements, ensuring that data is retained for a specified period to meet legal obligations.

Which data classification method categorizes data based on its sensitivity and criticality?

  1. Data lineage

  2. Data profiling

  3. Data classification

  4. Data retention


Correct Option: C
Explanation:

Data classification involves categorizing data into different classes based on its sensitivity, criticality, and regulatory requirements.

What is the process of identifying, classifying, and labeling data according to its sensitivity and criticality called?

  1. Data governance

  2. Data retention

  3. Data classification

  4. Data lineage


Correct Option: C
Explanation:

Data classification is the process of identifying, classifying, and labeling data according to its sensitivity and criticality, enabling organizations to manage and protect data effectively.

Which data lifecycle phase involves transforming raw data into a more usable and meaningful format?

  1. Storage

  2. Processing

  3. Acquisition

  4. Retention


Correct Option: B
Explanation:

Processing is the phase where raw data is transformed into a more usable and meaningful format through various operations such as cleaning, filtering, and aggregation.

What is the primary goal of data retention policies?

  1. To ensure data integrity and accuracy

  2. To optimize data storage and reduce costs

  3. To protect data from unauthorized access

  4. To comply with legal and regulatory requirements


Correct Option: D
Explanation:

Data retention policies are primarily implemented to comply with legal and regulatory requirements, ensuring that data is retained for a specified period to meet legal obligations.

Which data lifecycle phase involves storing data in a secure and accessible manner?

  1. Storage

  2. Processing

  3. Acquisition

  4. Retention


Correct Option: A
Explanation:

Storage is the phase where data is stored in a secure and accessible manner, enabling authorized users to retrieve it when needed.

What is the process of tracking the movement and transformation of data throughout its lifecycle called?

  1. Data lineage

  2. Data profiling

  3. Data classification

  4. Data retention


Correct Option: A
Explanation:

Data lineage is the process of tracking the movement and transformation of data throughout its lifecycle, providing a comprehensive understanding of data provenance and dependencies.

Which data lifecycle phase involves the systematic disposal or archiving of data that is no longer needed?

  1. Storage

  2. Processing

  3. Acquisition

  4. Disposition


Correct Option: D
Explanation:

Disposition is the phase where data that is no longer needed is systematically disposed of or archived, ensuring compliance with data retention policies and regulations.

What is the primary objective of data governance?

  1. To ensure data integrity and accuracy

  2. To optimize data storage and reduce costs

  3. To protect data from unauthorized access

  4. To establish policies and procedures for managing data


Correct Option: D
Explanation:

Data governance aims to establish policies, procedures, and standards for managing data, ensuring its integrity, security, and compliance with regulatory requirements.

Which data lifecycle phase involves monitoring and maintaining data quality and accuracy?

  1. Storage

  2. Processing

  3. Acquisition

  4. Quality Assurance


Correct Option: D
Explanation:

Quality Assurance is the phase where data quality and accuracy are monitored and maintained, ensuring that data meets the required standards and is fit for its intended purpose.

What is the process of identifying and removing duplicate or redundant data from a dataset called?

  1. Data deduplication

  2. Data profiling

  3. Data classification

  4. Data retention


Correct Option: A
Explanation:

Data deduplication is the process of identifying and removing duplicate or redundant data from a dataset, optimizing storage space and improving data quality.

Which data lifecycle phase involves analyzing data to extract meaningful insights and patterns?

  1. Storage

  2. Processing

  3. Analytics

  4. Retention


Correct Option: C
Explanation:

Analytics is the phase where data is analyzed to extract meaningful insights, patterns, and trends, enabling organizations to make informed decisions.

What is the process of converting unstructured data into a structured format for easier analysis and processing called?

  1. Data wrangling

  2. Data profiling

  3. Data classification

  4. Data retention


Correct Option: A
Explanation:

Data wrangling is the process of converting unstructured data into a structured format, making it easier to analyze and process, and enabling the extraction of valuable insights.
