A system administrator notices that a newly provisioned server cannot reach destinations outside its local subnet. Arrange the diagnostic actions in the correct logical sequence following standard CompTIA troubleshooting methodology.
- 1Verify the server's local IP address, subnet mask, and default gateway configuration.
- 2Ping the IP address of the local default gateway from the server.
- 3Execute a traceroute command to the remote destination IP address.
- 4Inspect the default gateway router's IP routing table and active inbound/outbound ACL rules.
Cevap
The proper troubleshooting sequence begins with verifying local host network settings, testing reachability to the local default gateway via ping, performing a traceroute to isolate the path failure hop, and inspecting the gateway router's routing table and access control lists.
Logical network troubleshooting flows systematically from the local host up through the network path. First, local interface configurations must be verified. Second, connectivity to the immediate gateway is tested. Third, traceroute isolates where remote forwarding fails. Finally, deep analysis of router ACLs and routing tables is performed at the point of failure.
