Question 28

Explanation

The correct answer: A digital signature is used to authenticate the identity of the sender and ensure the integrity of the document being signed. In the scenario of signing a contract with a new business partner, a digital signature would provide both parties with confidence in the legitimacy of the agreement. The incorrect answers: When sending a password reset email to a user, a digital signature is not necessary as the email itself is not a legally binding document. Additionally, a password reset email would typically be sent through a secure system that already has authentication measures in place. When transmitting sensitive financial information over a public network, a digital signature is not sufficient to protect the information from potential attackers. Encrypting the data would be a more effective security measure in this scenario. When updating the company's employee database, a digital signature is not necessary as the database itself is not a legally binding document. The database would typically have its own security measures in place to protect the information from unauthorized access.
