Which of the following actions should be taken when transmitting data to mitigate the chance of a data leak occurring? (Choose two.)
The correct answer is D. Data encryption E. Data masking. Data encryption converts data into an unreadable format using cryptographic keys so that even if the data is intercepted during transmission, it cannot be understood by unauthorized parties. This is the primary defense against data leaks in transit (e.g., TLS/SSL). Data masking…

Explanation
Data encryption converts data into an unreadable format using cryptographic keys so that even if the data is intercepted during transmission, it cannot be understood by unauthorized parties. This is the primary defense against data leaks in transit (e.g., TLS/SSL). Data masking replaces sensitive data elements (such as credit card numbers or SSNs) with anonymized or obfuscated values, ensuring that even if data is exposed, the actual sensitive information is not revealed. Together, encryption and masking provide layered protection. Data identification, processing, and reporting are data management activities, not security controls for transmission. Data removal eliminates data entirely and does not apply to the context of secure transmission.
