Free CompTIA Cloud+ Data Security Questions and Answers

Question 1

Which of the following best describes data encryption?

Accepted Answer

The practice of converting data into an unreadable format to prevent unauthorized access

Answer

Data encryption is the practice of converting data into an unreadable format, known as ciphertext, using an algorithm and an encryption key. This process prevents unauthorized access by rendering the data unintelligible to anyone without the correct decryption key. It is a fundamental security measure for protecting sensitive information both at rest and in transit.

Question 2

What is the primary purpose of a cloud access control policy?

Accepted Answer

To define who can access cloud resources and at what level

Answer

The primary purpose of a cloud access control policy is to define precisely who can access cloud resources and at what level of permission. These policies establish rules and roles that dictate which users or systems are authorized to perform specific actions on particular resources. This ensures that only authenticated and authorized entities can interact with sensitive data and infrastructure, preventing unauthorized access and misuse.

Question 3

Which of the following is an example of data at rest?

Accepted Answer

Data stored in a database on a cloud server

Answer

Data at rest refers to data that is stored physically in any digital format, such as on hard drives, databases, or storage devices, and is not actively moving across a network or being processed. Therefore, data stored in a database on a cloud server is a prime example of data at rest. This distinguishes it from data in transit (moving across a network) or data in use (being actively processed).

Question 4

What is a common method for securing data in transit?

Accepted Answer

Transport Layer Security (TLS) encryption

Answer

Transport Layer Security (TLS) encryption is a common and highly effective method for securing data in transit across networks, including the internet. TLS establishes an encrypted connection between a client and a server, ensuring the confidentiality and integrity of the data exchanged. This protocol protects information from eavesdropping, tampering, and message forgery, making it crucial for secure communication.

Question 5

What is the function of a cloud Data Loss Prevention (DLP) solution?

Accepted Answer

To detect and prevent unauthorized data transfers

Answer

The function of a cloud Data Loss Prevention (DLP) solution is to detect and prevent unauthorized data transfers, whether intentional or accidental, from leaving the organization's control. DLP tools identify sensitive information and enforce policies to block or alert on attempts to share, move, or exfiltrate that data. This helps protect confidential information, prevent data breaches, and ensure compliance with regulatory requirements.
