Lesson 22—Manage Advanced Network Settings Flashcards
What’s a network location? Who can access network locations?
A network location is a saved state of Network preferences that contains all network interface settings. Only administrators can define network locations, but if more than one location exists, all users can use the Apple menu to switch between the various network locations.
Which 11 interfaces and protocols are supported by default in macOS Big Sur?
• Ethernet IEEE 802.3 family of hardware network interface standards
• Wireless (Wi-Fi) IEEE 802.11 family of hardware network interface standards
• Thunderbolt Bridge network interface
• Bluetooth wireless hardware network interface
• Cellular networks that use USB adapters or iOS devices with cellular network service (Personal Hotspot)
• VPN interface through Layer 2 Tunneling Protocol (L2TP) over Internet Protocol Security (IPSec), Cisco’s IPSec, and Internet Key Exchange version 2 (IKEv2)
• TCP/IP, also known as the Internet protocol suite
• DHCP
• DNS protocol
• Network Basic Input/Output System (NetBIOS) and Windows Internet Naming Service (WINS)
protocols
• Authenticated Ethernet through the 802.1X protocol
How does network service order affect network connectivity?
The network service order list is used to determine the primary network service interface if more than one service is active. All network traffic that isn’t better handled through a local connection to an active network service interface is sent to the primary network service interface. So in most cases, all WAN traffic, internet traffic, and DNS resolutions are sent through the primary network service interface.
How can you tell which interface is currently being used for network activities in Network preferences?
In Network preferences, network service interfaces with a green status indicator are being used for network activities. All network traffic that isn’t better handled through a local connection is sent to the primary network service interface. The primary network service interface is the topmost active interface in the listing. You can manually reorder the network service order by dragging them into the order you prefer. Active services will still have priority over inactive services.
What’s the easiest way to configure virtual private network (VPN) settings in macOS Big Sur?
Use a configuration profile containing all the relevant VPN setup information.
How is 802.1X configured on Mac computers?
- Automatic configuration through the selection of a Wi-Fi network that requires WPA/WPA2/WPA3/ Enterprise authentication
- Semiautomatic configuration through an 802.1X configuration profile provided by an administrator
