FC0-U71 Data and Database Fundamentals Practice Question

A database designer is normalizing a table that contains repeating groups (multiple values in one column). Which of the following are goals of normalization? (Select THREE.)

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Eliminate update anomalies

Normalization aims to reduce redundancy, enforce data integrity, and eliminate update anomalies. It rarely improves query performance (often may reduce it due to more joins).

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Simplify the database schema

    Why it's wrong here

    Normalisation eliminates data redundancy and update anomalies by decomposing tables into smaller, related structures, which actually increases schema complexity rather than reducing it. The goal is to remove repeating groups through atomicity and dependency enforcement, not to simplify the schema. This option is tempting because simplifying a schema is a common database design objective, and it would be correct in a scenario where denormalisation is intentionally applied to improve read performance by reducing join operations.

  • Improve query performance

    Why it's wrong here

    Normalization can sometimes decrease performance due to more joins.

  • Eliminate update anomalies

    Why this is correct

    Correct; normalization reduces anomalies when updating data.

  • Reduce data redundancy

    Why this is correct

    Correct; normalization removes duplicate data.

  • Enforce data integrity

    Why this is correct

    Correct; normalization helps maintain data consistency.

Same concept, more angles

2 more ways this is tested on FC0-U71

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.

Variation 1. Which of the following best describes normalization in a relational database?

medium
  • A.Encrypting sensitive data in the database
  • B.Removing duplicate data from a table
  • C.Increasing the number of tables to improve performance
  • D.Combining all data into a single table

Why B: Normalization is the process of organizing data to reduce redundancy and improve data integrity.

Variation 2. A database designer wants to split a table into two to reduce data redundancy and avoid update anomalies. This process is known as:

medium
  • A.Normalization
  • B.Denormalization
  • C.Indexing
  • D.Partitioning

Why A: Normalization is the process of organizing data to reduce redundancy and improve integrity.
