Discussion
Consider the following statements about container image provenance.
1. Images should be scanned for known vulnerabilities before use.
2. Pinning to a digest rather than a mutable tag improves reproducibility.
3. A tag such as latest guarantees a specific image version.
Answer: B
Correct answer: 1 and 2 only
Statements 1 and 2 are sound practice: scanning catches known vulnerabilities before deployment, and pinning to an immutable digest guarantees that the same bytes are deployed every time. Statement 3 is the misconception the second addresses - a tag is a mutable pointer, and latest in particular is whatever was pushed most recently, so the same manifest can yield different images on different days.
