Answer: B. Perform a hash on the file for comparison with the vendor’s hash.

Explanation:

Before installing the firmware update, the step that the technician should perform to ensure file integrity is to perform a hash on the file for comparison with the vendor’s hash.

Hashing refers to the algorithm that is used for the calculation of a string value from a file. Hashes are helpful in the identification of a threat on a machine and when a user wants to query the network for the existence of a certain file.
