Dell EMC Associate – Information Storage and Management v4 — Question 84

A company is planning to perform a cloud-based backup. They want to send their data over a public network to a cloud backup device.
Which security control mechanism helps to protect the data from an attacker?

Answer options

• A. Multi-factor authentication
• B. Demilitarized zone
• C. Data shredding
• D. Encryption

Correct answer: D

Explanation

The correct answer is D, Encryption, as it secures data by converting it into a coded format, making it unreadable to unauthorized users during transmission over public networks. Multi-factor authentication (A) enhances login security but does not protect data in transit, while a Demilitarized zone (B) is used to separate internal networks from external ones but does not specifically secure data during transfer. Data shredding (C) is relevant for deleting data securely and does not apply to data in transit.
