CV0-004 Practice Question: During a deployment using a script, an…
During a deployment using a script, an administrator receives a 'Permission Denied' error. What is the most likely cause?
⚠ Common exam trap
CV0-004 often tests the distinction between authorization errors (permission denied) and other deployment issues like network or configuration errors; candidates may overlook IAM as the root cause.

Correct answer & explanation
✓
The service account lacks necessary IAM roles
The 'Permission Denied' error during a scripted deployment most commonly occurs when the identity executing the script (e.g., a service account) lacks the necessary IAM permissions to perform the required actions, such as creating or modifying resources. IAM roles define what actions are allowed, so missing roles directly cause authorization failures. Network latency, wrong region, or insufficient storage would typically produce different errors (timeouts, resource not found, or disk full).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The service account lacks necessary IAM roles
Why this is correct
The deployment script authenticates as a service account, and 'Permission Denied' indicates that identity lacks the IAM roles required for the API calls it makes. Granting the missing roles resolves the authorisation failure, directly addressing the insufficient privileges constraint in the stem.
- ✗
Network latency is causing timeouts
Why it's wrong here
Latency produces timeouts or connection resets, not an explicit authorisation rejection from the target system. It is tempting because slow links do fail scripted deployments, but that scenario yields timeout or unreachable errors, and latency tuning is the right fix when transfers stall rather than being refused outright.
- ✗
The deployment is targeting the wrong region
Why it's wrong here
Region selection affects endpoint hostnames and data-residency, not filesystem or API authorisation, so it cannot produce 'Permission Denied'. It is tempting because misconfigured regions do break deployments, but that manifests as connection or resource-not-found errors, and choosing the correct region matters when provisioning geo-restricted services.
- ✗
The instance has insufficient storage
Why it's wrong here
Insufficient storage produces disk-full or write failures, not permission denials. A 'Permission Denied' error indicates the executing account lacks the required rights or ownership on the script or target path, which is the access-control problem to investigate.
