True or False: In the data life cycle of an information system, data is immediately deleted the moment it is classified as obsolete, skipping the archival phase entirely.
Show answer details
Correct answer: B
False. In a standard Data Life Cycle Management (DLM) process, data that is no longer actively used is typically archived first. It enters the obsolescence phase when it is no longer relevant even for historical purposes, and only then is it securely deleted based on organizational retention policies.

A senior data analyst at AeroDynamics Corp is tasked with documenting the workflow of a retiring master technician. The technician's unique troubleshooting methods and undocumented shortcuts significantly improve factory output, but they have never been recorded in the official company manuals. What type of data is the analyst attempting to capture, and why is it critical to the organization?
Show answer details
Correct answer: B
Institutional knowledge (often referred to as tribal knowledge) consists of the unwritten, tacit rules, processes, and insights that employees develop over time. Capturing this data is critical for organizations because it directly impacts efficiency and quality, and it is permanently lost if the employee leaves without transferring that knowledge.

When designing a new data architecture for a logistics company, the database administrator must choose the appropriate data structures for different types of information. Which TWO of the following statements correctly distinguish tabular data structures from hierarchical tree structures? (Select TWO)
Show answer details
Correct answer: A, C
Tabular data structures organize data into intersecting rows (records) and columns (attributes), which is the foundational structure of relational databases (RDBMS). Tree structures, conversely, map parent-child relationships and are better suited for hierarchical data like organizational charts or XML/JSON documents.
Tree structures map parent-child relationships, making them ideal for representing organizational charts or nested XML documents. Tabular structures organize data into rows and columns.
