Part 6 Network Configuration: Lesson 23 Flashcards
What interfaces and protocols are supported by default in OS X?
OS X supports the following network interfaces and protocols:
Wired ethernet IEEE 802.3 family of hardware network interface standards
Wireless Wi-Fi IEEE 802.11 family of hardware network interface standards
FireWire IEEE 1394 hardware network interface
Bluetooth wireless hardware network interface
USB connectivity via cellular network adapters
Virtual private network (VPN) virtual network interface via the Point-to-Point Tunneling Protocol (PPTP)
VPN virtual network interface via the Layer 2 Tunneling Protocol (L2TP) over Internet Protocol Security (IPSec)
Point-to-Point Protocol over Ethernet PPPOE virtual network interface
6 to 4 virtual network interface
Virtual local area network (VLAN) virtual network interface via the IEEE 8802.1Q standard
Link aggregation virtual network interface via the IEEE 802.3ad standard
Transmission Control Protocol/Internet Protocol (TCP/IP), also known as the Internet protocol suite
Dynamic Host Configuration Protocol (DHCP)
Network Basic Input/Output System (NetBIOS) and Windows Internet Naming Service (WINS) protocols
Authenticated Ethernet via the 802.1 X protocol
Point-to-Point Protocol (PPP)
What is the network location? You can access network locations?
A network location is a State of the Network preference that contains all network interface settings. Only administrators can define network locations, but if more than one location exists, all users can switch between the various network location via the Apple menu.
What functionality does OS X support with the AppleTalk protocol?
OS X doesn’t support AppleTalk.
How does network service order affect network connectivity?
The network service order list is used to determine the primary network service interface if there’s more than one active service. All network traffic that isn’t better handled via local connection to an active network service interface is sent to the primary network service interface. Thus, in most cases all WANT traffic, Internet traffic, and DNS resolution is sent through the primary network service interface.
In the Network preference, how can you tell which interface is currently being used for network activities?
In the Network preference, all network service interfaces with a green status indicator are being used for network activities. However, again, all network traffic that isn’t better handled via a local connection is sent to the primary network service interface. The primary network service interface is the topmost active interface in the listing.
What is the easiest method on OS X to configure VPN settings?
The easiest method to configure VPN settings is to use the configuration profile containing all the relevant VPN setup information.
How is 802.1 X configured on OS X systems?
On OS X, there are two configuration methods for 802.1 X. The first method is automatic configuration via the selection of a Wi-Fi network that requires WPA/WPA2 Enterprise authentication. The second method is “semi automatic” configuration via an administrator-provided 802.1 X configuration profile.
