Question 1 of 30

In a financial institution, the database administrator is tasked with implementing a security measure to protect sensitive customer data stored in the database. The administrator decides to use Transparent Data Encryption (TDE) to ensure that the data is encrypted at rest. Which of the following statements best describes the implications and operational characteristics of TDE in this scenario?

TDE encrypts data at rest without requiring changes to existing applications, and it utilizes a master key stored in a secure location for encryption management.

TDE requires significant modifications to application code to handle encryption and decryption processes, which can lead to increased development time and costs.

TDE only encrypts data in transit, leaving data at rest vulnerable to unauthorized access unless additional measures are implemented.

TDE is limited to encrypting specific columns in a table and cannot be applied to entire tablespaces or databases, restricting its usability in large-scale environments.
