Which of the following should a technician perform to verify the integrity of a file transferred from one device to another?

Rationale

Hashing

To verify the integrity of a file transferred from one device to another, a technician should perform hashing. Hashing involves generating a unique fixed-size string of characters based on the contents of the file. By comparing the hash value before and after transfer, the technician can determine if the file remains unchanged.

A (Authentication) YOUR ANSWER

Authentication involves verifying the identity of users or devices to ensure they are who they claim to be. While crucial for security purposes, authentication does not directly address file integrity verification during transfer.

B (Obfuscation) YOUR ANSWER

Obfuscation aims to make data unclear, confusing, or unintelligible to unauthorized parties. It is used to protect sensitive information but does not inherently validate the integrity of a file during transfer.

D (Encryption) YOUR ANSWER

Encryption secures data by transforming it into a coded format that can only be accessed with the appropriate decryption key. While encryption safeguards data confidentiality, it does not specifically focus on checking file integrity post-transfer.

Conclusion

In the context of verifying file integrity during transfer, hashing stands out as the most suitable option among the provided choices. By calculating and comparing hash values before and after transfer, technicians can effectively confirm whether a file has remained unaltered during the transmission process, ensuring data integrity and security.
