It runs faster queries.
It creates automatic indexes.
It enforces stronger security.
It may contain duplicate records. (Correct answer)

Correct answer: It may contain duplicate records.

If a table lacks a primary key, there is no mechanism to uniquely identify each row within that table. This means the database system cannot prevent the insertion of identical records, leading to data redundancy and potential inconsistencies. A primary key is crucial for data integrity and for establishing reliable relationships with other tables.

Question 33: Which documentation & best practices practice is MOST critical for maintaining data integrity in Access Data?

Manual data entry without verification

Correct answer: Data parsing and standardization

Data parsing and standardization breaks down free-form values and maps them to a consistent, canonical format based on defined rules or reference tables.

Question 46: What is the primary purpose of a checksum in data validation?

To encrypt sensitive fields
To detect errors introduced during data transmission or storage (Correct answer)
To enforce foreign key constraints
To normalize numeric values

Correct answer: To detect errors introduced during data transmission or storage

A checksum is a calculated value used to verify data integrity by detecting accidental changes or corruption during transmission or storage.

To encrypt redundant records for archival
To partition large tables into smaller ones for performance
To identify and remove or merge duplicate records that represent the same real-world entity (Correct answer)
To convert data from one format to another

Correct answer: To identify and remove or merge duplicate records that represent the same real-world entity

Data deduplication finds and resolves records that refer to the same entity but appear multiple times, improving accuracy and reducing storage waste.

User email domain.
User roles. (Correct answer)
Time of access.
Table size.

Correct answer: User roles.

Role-Based Access Control (RBAC) is an access control model that regulates access to resources based on the individual's role within an organization. Instead of assigning permissions directly to users, permissions are assigned to specific roles, and users are then assigned to one or more roles, simplifying access management and ensuring consistent security policies.

Question 66: A 'uniqueness' constraint in data quality is violated when:

A date field contains a future date
A required field is left blank
Two records share a value that should be exclusive to one record (Correct answer)

Question 69: How can you sort data in ascending or descending order in SQL?

GROUP BY
FILTER
ORDER BY (Correct answer)
SORT

Correct answer: ORDER BY

The `ORDER BY` clause in SQL is used to sort the result set of a query. You can specify one or more columns to sort by, and choose between ascending (`ASC`) or descending (`DESC`) order. This helps in presenting data in a structured and easily understandable manner, making it easier to analyze.

Question 73: Which element helps users interpret values in a chart?

Legend (Correct answer)
Gridline
Axis labels
Title bar

Correct answer: Legend

A legend in a chart is a key that identifies the different data series, categories, or elements represented by colors, patterns, or symbols within the visualization. It is crucial for helping users interpret what each visual component signifies, ensuring clarity and understanding of the presented data.

Question 74: What is the principle of least privilege?

Users get minimum access rights. (Correct answer)
Guests get more access.
All users are administrators.
Everyone has full access.

Correct answer: Users get minimum access rights.

The Principle of Least Privilege dictates that users, programs, or processes should be granted only the minimum necessary permissions to perform their specific tasks. This security best practice limits the potential damage from compromised accounts or systems, reducing the attack surface and preventing unauthorized actions.

Question 75: In AccessData FTK, what does 'bookmarking' evidence items enable?

Permanently deleting files
Compressing the forensic image
Encrypting case files
