PCNSA Device Management and Services Practice Question

A security administrator notices that a user's traffic is being blocked unexpectedly. The user's IP is 10.1.1.100, and the traffic is destined to a web server at 192.168.2.10. The administrator has already verified that there are no security rules explicitly denying the traffic. Which Log Viewer query should the administrator use to quickly identify the cause?

⚠ Common exam trap

Watch out — candidates often assume a block must be due to a threat or misconfiguration, leading them to check Threat or Config logs, but the correct approach is to examine Traffic logs where the firewall records all session dispositions, including implicit denials.

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

Search Traffic logs with filters for source 10.1.1.100 and destination 192.168.2.10

Traffic logs capture every session that passes through the firewall, including allowed and denied connections. By filtering for the specific source IP (10.1.1.100) and destination IP (192.168.2.10), the administrator can quickly see the exact session details, including the action taken (e.g., deny, drop) and the reason (e.g., no matching rule, application override). This is the most direct method to identify why traffic is being blocked when no explicit deny rule exists.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Search Traffic logs with filters for source 10.1.1.100 and destination 192.168.2.10

    Why this is correct

    Traffic logs show the action (allow/deny/drop) for each session, and filtering by IPs narrows down the specific session.

  • Search Threat logs for the destination IP

    Why it's wrong here

    Threat logs only show blocked threats, not all dropped traffic.

  • Search Config logs for any rule changes

    Why it's wrong here

    Config logs show configuration changes, not traffic handling.

  • Search System logs for the user's IP

    Why it's wrong here

    System logs are for administrative events, not traffic flows.

Visual reference

Source Router + ACL permit 10.0.0.0/8 deny any Server 10.0.0.5 ✓ 192.168.1.1 ✗ dropped ACLs evaluate top-down; first match wins — implicit deny all at end
