A macOS user is on a network that requires a proxy for internet access. The user can reach internal servers but not external websites. You verify that the proxy settings in System Settings are correct. What should you check next?

Whether the proxy server is reachable from the Mac

Whether the Mac's DNS is set to the corporate DNS

Whether the Mac's firewall is blocking Safari

Whether the Mac is using the correct Wi-Fi network

A small office uses a Wi-Fi network with WPA2-PSK. A user's Android phone connects but the iOS tablet cannot connect, even though both devices are in the same location. The SSID and password are correct. What is the most likely cause?

The iOS device is configured for WPA3-Enterprise instead of WPA2-PSK

The Wi-Fi router is broadcasting on a 5 GHz band only

The iOS device has a VPN enabled

The Android phone is using a static IP address

Which Android setting allows you to view the IP address assigned to your device on a Wi-Fi network?

Settings > Storage > IP address

Settings > Network & internet > Wi-Fi > tap the connected network > View details

Settings > Security > IP address

Settings > Display > IP address

A Linux administrator needs to temporarily assign the IP address 192.168.1.100/24 to interface eth0 for testing. The change must not survive a reboot. Which command accomplishes this?

echo '192.168.1.100/24' > /etc/network/interfaces

nmcli con mod eth0 ipv4.addresses 192.168.1.100/24

ip addr add 192.168.1.100/24 dev eth0

ifconfig eth0 192.168.1.100 netmask 255.255.255.0 up
