Apple OS X Support Essentials 10.9 Sample Questions:
1. How can an OS X system automatically connect to a Wi-Fi network?
A) A new OS X system can only automatically connect to Wi-Fi networks that have no standard authentication mechanism, otherwise known as an "open network." However, a configured OS X system can automatically reconnect to authenticated Wi-Fi networks, provided that the appropriate information was saved to the Keychain system.
B) A standard user can connect to any non-WPA Enterprise Wi-Fi network via the Wi-Fi status menu. Because the system Keychain must be modified for WPA Enterprise connections, only an administrative user can establish these types of connections.
C) The Activity Monitor application is used to monitor open processes and applications.
D) Code-signed items include a digital signature that the system can use to verify the authenticity and integrity of the application or process and its resources.
2. On a Mac running OS X Mountain Lion, how can you display a list of installed software updates?
A) Open Software Update preferences and click Installed Software.
B) Open System Information, click System Report, and then in the sidebar under Software, click Installations.
C) Open Software Update and click Receipts.
D) Open Installer, choose Show Files from the File menu, and then in the Files section under /var/log/, select install.log.
3. How does a user that changes his own account password affect his login keychain?
A) When a user changes his own account password, the system will keep his login keychain password in sync.
B) The Archive option in the Finder creates compressed zip archive files.
C) The master password is used to reset local account passwords.
D) Time Machine starts with a full copy of the file system to the backup disk. Then it maintains a list of changes to the file system, and every hour copies only the changes to the backup disk. In the backup, it creates a simulation of the full file system using hard links for files that haven't changed.
4. How do ACLs differ from standard UNIX file systempermissions?
A) An item's ownership and permissions can be identified using the Info or Inspector windows in the Finder.
