The Chief Information Officer (CIO) of a datacenter is concerned that transmissions from the building can be detected from the outside. Which of the following would resolve this concern? (Choose two.)

• A. RFID
• B. Proximity readers
• C. Virtual private network (VPN)
• D. Data encryption methods

Answer: (A)

The concerns of the Chief Information Officer regarding external detection of transmissions are best addressed by selecting methods that enhance the security and privacy of the data being transmitted.

Using virtual private networks (VPNs) is vital as they create encrypted tunnels for data transmission over public networks. This means that even if data packets are intercepted, they remain unreadable to unauthorized parties, thus ensuring confidentiality and mitigating the risk of detection.

Data encryption methods complement this by applying algorithms to ensure that the information remains secure during transit, making it inaccessible to anyone who manages to intercept it. Encryption converts readable information into a coded format, requiring an access key for decryption, thereby providing an additional layer of security.

Each of these solutions reinforces data integrity and confidentiality, ensuring that transmissions from the datacenter are shielded from external detection and unauthorized access.
