CV0-004 Practice Question: A company uses a cloud-based logging service to…
A company uses a cloud-based logging service to aggregate logs from multiple servers. Suddenly, the logging service stops receiving logs from several servers. The administrator checks the logging agent status on those servers and finds that the agents are running but not sending data. The network connectivity between the servers and the logging service is verified as working. Which of the following is the MOST likely cause?
⚠ Common exam trap
Many exam-takers assume a running agent implies correct configuration, but agents can run idle if they cannot reach or authenticate to the configured endpoint, even when network connectivity is fine.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The logging endpoint configuration on the agents is incorrect.
The logging agents are running but not sending data, and network connectivity is verified as working. This points to a configuration issue where the agents are pointing to an incorrect logging endpoint (e.g., wrong URL, port, or API key). Even if the service is healthy, misconfigured agents will fail to transmit logs, which matches the symptom of agents running but idle.
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 logging service has reached its storage quota.
Why it's wrong here
A full storage quota stops the service accepting logs, but agents would usually receive errors or back-pressure rather than silently running. It is tempting because quota exhaustion halts ingestion, yet the symptom of multiple agents running without sending points to a common configuration or credential change.
- ✓
The logging endpoint configuration on the agents is incorrect.
Why this is correct
Agents running but silent, with verified network connectivity, points to misconfiguration rather than transport failure. If the endpoint address or port the agent sends to is wrong, logs never reach the service, satisfying the stem's constraint that connectivity works while data flow does not.
- ✗
The logging agent is out of memory.
Why it's wrong here
An out-of-memory agent would typically crash or restart, yet the agents are reported running. It is tempting because resource exhaustion does stop log forwarding, but the stem specifies running agents, pointing instead to a shared upstream cause affecting several servers simultaneously.
- ✗
A firewall is blocking the outbound traffic from the servers.
Why it's wrong here
A firewall blocking outbound traffic contradicts the verified working network connectivity between servers and the logging service. It is tempting because firewalls commonly block log shipping, but the stem rules this out, leaving a shared agent-side configuration or authentication failure as the likely cause.
