Your network has a dozen computers, all sharing a single public IP address. One of them is an FTP server. What kind of rule will you need to configure to allow FTP users to connect from the internet?

• Port Address Translation
• Port Forwarding
• Port Triggering
• Universal Plug and Play

Even if your router uses DHCP, it might be able to make sure a given client always receives the same IP address.

• true
• False.

What issues might you try to fix by adjusting your router's QoS settings?

• A critical server keeps experiencing high network latency
• Large file downloads are frequently corrupted
• Network connections frequently drop
• Some Internet websites are frequently slow
• Voice over IP calls are choppy during busy network times

Your crowded building hosts a number of nearby Wi-Fi hotspots. The nearest neighbor is on an adjacent channel to your own. Is that a problem?

• Yes
• No
• Only if it's in the 2.4GHz band
• Only if it's in the 5GHz band.

Defense in depth is a good idea for any network, but not all layers are equally important on every network.

• true
• False.

You've set a Wi-Fi password, but you'd like some extra protection against unauthorized clients connecting to the network. What feature should you enable?

• Content filtering
• DHCP server
• MAC filtering
• Port forwarding

You've just installed a router fresh out of the box. Which configuration changes should you make to improve its default security?

• Change the default user name and password
• Close unnecessary ports and services
• Configure QoS
• Disable remote administration
• Enable UPnP

Your WAP uses WPA2-AES and WPS. SSID is disabled. Which change should you make to increase security?

• Disable WPA
• Disable WPS
• Enable SSID
• Enable TKIP

You're installing a smart home system on your home office network, with light switches, thermostat, and security cameras all controlled through a voice-activated smart speaker. Which points should you keep in mind when configuring them?

• A network-based firewall should be configured to protect all devices.
• Each device should have a host-based firewall installed and configured.
• If possible, you should consider putting them on a separate network segment from other computers for security reasons.
• There is no standard way to join all devices to the network, so make sure to read individual documentation.
• To manage them all, you'll need a cloud-based solution such as Google Cloud IoT, AWS IoT Device Management, or Azure IoT Hub.

A printer in the office produces high quality color photos, but it's bulky and needs time to heat up after you turn it on. What technology does it likely use?

• Impact
• Inkjet
• Laser
• Thermal
