Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
An attacker altering container image layers stored in an insecure registry
Why this is correct
Modifying image contents in a registry constitutes tampering with the software supply chain.
- ✓
An attacker modifying Kubernetes API objects stored directly or in transit via compromised credentials
Why this is correct
Unauthorized modification of Kubernetes manifests or cluster state objects represents tampering with data.
- ✗
An attacker flooding the API server with requests to exhaust control plane memory
Why it's wrong here
Flooding for resource exhaustion is Denial of Service, not Tampering.

An attacker sniffing unencrypted pod-to-pod network traffic across the CNI bridge
Why it's wrong here
Sniffing traffic is Information Disclosure, not Tampering.
- ✗
An administrator denying that they executed a cluster deletion command due to missing logs
Why it's wrong here
Denying actions due to absent audit trails is Repudiation, not Tampering.
