🛡️ Free practice test question from: race condition (Security+)

Atomic database transactions ensure that a series of operations either all occur successfully or none do, maintaining data consistency. In the context of preventing race conditions, atomic transactions can lock the relevant data (e.g., the coupon count) during the operation, preventing multiple simultaneous modifications. This ensures that once a coupon is being applied, no other coupon can be applied until the first transaction is complete, effectively preventing multiple coupons from being applied to the same cart.

A) (Rate limiting) can help reduce the number of attempts but does not directly address the race condition.

C) (Encrypting data transmissions) enhances data security but does not prevent race conditions.

D) (Client-side validation) is insufficient as attackers can bypass client-side controls.
