CV0-004 Practice Question: A deployment fails with a message about missing…
A deployment fails with a message about missing dependencies. What should the administrator check first?
⚠ Common exam trap
Many exam-takers assume a generic 'fix' like restarting or resizing the instance will resolve the issue, when the specific error message about missing dependencies demands log inspection to identify and install the exact missing packages.

Correct answer & explanation
✓
Review the deployment logs to identify missing packages
When a deployment fails with a 'missing dependencies' message, the first step is to review the deployment logs. Logs will contain specific error messages indicating which packages or libraries are absent, allowing the administrator to install them directly. This aligns with standard troubleshooting methodology: identify the root cause from logs before taking corrective action.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Change the instance type to one with more memory
Why it's wrong here
Memory exhaustion produces out-of-memory or allocation errors, not a missing-dependency message; the dependency list and repository access are the relevant checks. Larger instance types suit workloads terminated for memory pressure, which is a different failure signature entirely.
- ✓
Review the deployment logs to identify missing packages
Why this is correct
Reviewing the deployment logs directly exposes which dependency resolution failed, satisfying the need to identify the missing packages before remediation. Logs record the exact package names and versions the installer could not locate, so the administrator gains the specific evidence required rather than guessing at causes.
- ✗
Reinstall the operating system
Why it's wrong here
Reinstalling the operating system destroys the environment without resolving which dependency is absent; the deployment manifest or package repository must be inspected. OS rebuilds suit corrupted system files or failed upgrades, not a resolvable missing-package error surfaced by the deployment tool.
- ✗
Restart the server and retry the deployment
Why it's wrong here
Restarting the server leaves the absent dependency absent, so the same error recurs; the package source or manifest must be examined. Restarts suit transient runtime faults such as hung services or stale sockets, not a deterministic resolution failure reported before the application starts.
