Question 35 CITY_GUILDS_MODEL_QUESTIONS_VOL1 • 2018 • INFORMATION_TECHNOLOGY • objective

A workstation is connected to a Wi‑Fi network and obtains the address \(192.168.1.45\) with subnet mask \(255.255.255.0\) and default gateway \(192.168.1.1\). The DNS server is set to \(8.8.8.8\). When the user tries to browse any website, the browser shows the error "DNS_PROBE_FINISHED_NXDOMAIN". A ping to the default gateway succeeds, but a ping to \(8.8.8.8\) returns "Destination host unreachable". Another device on the same network can access the Internet without problems. Which single cause most plausibly explains all the observed symptoms?

A. Default gateway IP entered as 192.168.1.254 instead of 192.168.1.1

C. Subnet mask set to 255.255.0.0 causing routing confusion
D. Incorrect DNS server address configured on the workstation

Router's ACL/firewall blocking outbound traffic from the workstation
