Which statement best describes data in transit protection using TLS/HTTPS?

• A. TLS/HTTPS protects data in transit across networks.
• B. TLS/HTTPS protects data at rest on disks.
• C. TLS/HTTPS is used only for email encryption.
• D. TLS/HTTPS encrypts user passwords stored in databases.

Answer: (A)

The main idea is protecting data as it moves between endpoints. TLS/HTTPS creates an encrypted channel between a client and a server, so anything sent over the network remains confidential, tamper-evident, and verifiably from the intended server. This is about data in transit across networks, not about data stored on disks. TLS isn’t limited to email; it’s used for securing many protocols, and protecting passwords stored in databases would fall under data at rest or storage practices, not the in-transit protection TLS provides. So the best description is that TLS/HTTPS protects data in transit across networks by encrypting the communication channel, guarding against eavesdropping and tampering during transmission.
