Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Software License Agreement (SLA)
Why it's wrong here
The SLA is a legal document, not a security control for integrity.
- ✗
SHA-256 checksum published on a text file
Why it's wrong here
A checksum in a text file is easily spoofed if the file is also compromised.
- ✗
Vendor SOC 2 Type II report
Why it's wrong here
SOC 2 is an audit of organizational processes, not a technical check for code signing.
- ✓
Digital Signature (e.g., Authenticode or GPG)
Why this is correct
Digital signatures are the industry standard for verifying code integrity.
