Lesson 26 Flashcards
How does OS X use dynamic network service discovery protocols to access network services?
Devices providing a network service advertise their availability via a dynamic network service discovery protocol. Clients looking for services request and receive this information to provide the user with a list of available network service choices.
Which two dynamic network service discovery protocols are supported by OS X?
OS X supports Bonjour and Server Message Block (SMB), including support for legacy Network Basic Input/Output and Windows Internet Naming Service (NetBIOS and WINS) dynamic network service discovery protocols.
Which sharing services can OS X provide?
The OS X sharing services include DVD or CD sharing, Screen Sharing, File Sharing, Printer Sharing, Scanner Sharing, Remote Login, Remote Management (ARD), Apple Events, Internet Sharing, and Bluetooth Sharing.
What’s the security risk of enabling client sharing services?
If a client sharing service is compromised, an unauthorized user can control your Mac and execute unwanted applications or processes.
Which application can provide on-demand screen sharing even when the Screen Sharing service isn’t enabled?
The Messages application allows for on-demand screen sharing that can be used even when the system screen sharing service isn’t enabled.
What’s AirDrop, and how do you know if a specific Mac supports it?
AirDrop provides a quick and easy method to share files locally via Wi-Fi. AirDrop creates a secure peer-to-peer network between local devices. You can verify that a Mac supports AirDrop from the Finder Go menu.
How does the OS X built-in firewall work?
The OS X built-in firewall inspects each incoming network connection to determine if it’s allowed. Connections are allowed or denied on a per-application basis.
Which optional firewall settings are available?
The optional firewall settings let you control whether signed applications are automatically allowed through the firewall, control the list of allowed (or denied) applications, and enable stealth mode (which means your Mac won’t respond to any unsolicited connections).
