Question 1

Which method is MOST secure for disposing of sensitive data stored on magnetic hard drives?

Accepted Answer

Degaussing or physical destruction

Answer

Degaussing uses a powerful magnetic field to destroy data on magnetic media, while physical destruction (shredding/crushing) ensures data cannot be recovered by any means.

Question 2

Data sovereignty refers to the concept that:

Accepted Answer

Data is subject to the laws of the country in which it is stored or processed

Answer

Data sovereignty means that digital data is subject to the laws and governance structures of the nation where it is physically located, which has significant implications for cloud storage decisions.

Question 3

A company wants to ensure the integrity of backup data and prevent unauthorized tampering. Which control BEST addresses this requirement?

Accepted Answer

Using cryptographic hashing to verify backup integrity

Answer

Cryptographic hashing (e.g., SHA-256) generates a unique fingerprint of backup data; if any bit changes, the hash changes, immediately revealing tampering or corruption.

Question 4

Which key management practice is MOST critical for maintaining long-term data confidentiality?

Accepted Answer

Regularly rotating encryption keys and securely storing them separately from the data

Answer

Regular key rotation limits the exposure window if a key is compromised, and storing keys separately from encrypted data ensures that gaining access to the ciphertext alone is insufficient.

Question 5

What is the PRIMARY security concern when storing sensitive organizational data in a public cloud environment?

Accepted Answer

Loss of direct physical control over data and shared infrastructure risks

Answer

Public cloud environments introduce multi-tenancy risks, reduced physical control, and reliance on the provider's security controls, making data governance and shared responsibility models critical.
