Network Troubleshooting第 88 / 100 题
A user reports they can access internal resources but not the internet. Other users are unaffected. What should the technician check first on that host?
a.The entire building's fiber uplink
b.The core router's routing table
c.The host's default gateway and DNS settings
d.The ISP's SLA compliance
解析
Because only one user is affected, the problem is likely local to that host, so checking its default gateway and DNS settings comes first. A missing or wrong gateway would block internet access while local resources on the same subnet remain reachable. Isolating scope narrows the fault quickly.
