CompTIA ITF+ FC0-U61 Practice Question

The correct answer is to prevent unauthorized access. Default passwords are usually common and well-known to attackers, which makes devices with unchanged default passwords an easy target. Changing the default password to a unique, strong password reduces the risk of unauthorized access. Keeping the default password does not align with security best practices and may leave the network vulnerable. Adding features or capabilities is not directly related to the initial security step of changing the default password, and writing down passwords is generally considered insecure as it may lead to physical theft of the password information.
