CompTIA ITF+ (FC0-U61) — Question 115

Which of the following is a value that uniquely identifies a database record?

Answer options

• A. Foreign key
• B. Public key
• C. Primary key
• D. Private key

Correct answer: C

Explanation

The correct answer is C, Primary key, because it is specifically designed to uniquely identify each record in a database table. A Foreign key (A) relates to another table, while Public key (B) and Private key (D) are terms associated with encryption and security, not database record identification.
