What three security options does the Gatekeeper system allow? Which Gatekeeper option is the OS X default?

• A. A device driver is software specially designed to facilitate the communication between OS X and a peripheral. Devicedrivers can be kernel extensions, framework plug-ins, orstandalone applications.
• B. Any item downloaded using one of the built-in OS Xapplications will be marked for quarantine. Third-party applications may not mark downloaded items for quarantine.
• C. Gatekeeper can restrict software to Mac App Storeapplications only, or Mac App Store and identified developer applications only (this is the default option), or any application regardless of origin.
• D. You can prevent automatic updates for all users by disabling the options in App Store preferences. You can further restrict a user's ability to use the Mac App Store by configuring Parental Controls for the user's account.

What Wi-Fi authentication protocols are supported by OS X?

• A. Disk Utility is the primary application for creating and managing disk images.
• B. OS X supports the following network interfaces and protocols:
  Ethernet IEEE 802.3 family of hardware network interface standards
  Wireless (Wi-Fi) IEEE 802.11 family of hardware network interface standardsFireWire IEEE 1394 bridged network interface
  Thunderbolt bridged network interface
  Bluetooth wireless hardware network interface
  USB connectivity via cellular network adapters or iOS devices with cellular network service
  Virtual private network (VPN) virtual network interface via the Point-to-Point TunnelingProtocol (PPTP)
  VPN virtual network interface via the Layer 2 Tunneling Protocol (L2TP) over InternetProtocol Security (IPSec)
  VPN virtual network interface via Cisco 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 802.1Q standard
  Link Aggregation virtual network interface via the IEEE 802.3ad standard
  Transmission Control Protocol/Internet Protocol (TCP/IP),alsoknown as the Internet protocolsuite
  Dynamic Host Configuration Protocol (DHCP)
  Domain Name Service (DNS) protocol
  Network Basic Input/Output System (NetBIOS) andWindows Internet Naming Service(WINS) protocols
  Authenticated Ethernet via the 802.1X protocol
• C. The Setup Assistant process guides a user through initial configuration of OS X Mavericks.
• D. OS X supports authenticated Wi-Fi via the followingauthentication protocols:WEP, WPA/WPA2 Personal, and WPA/WPA2 Enterprise, which includes support for 802.1Xauthentication.

At system shutdown, the loginwindow process logs all users out and tells the kernel to quit allremaining system processes. Once the kernel quits all system processes, the Mac shuts down.

• A. What are Safe Sleep and Power Nap?
• B. What happens during system shutdown?
• C. What are PPD files responsible for?
• D. What does the master password do?

You are unable to connect to a web server from your OS X Mountain Lion computer. How can traceroute help you troubleshoot this issue?

• A. Traceroute can determine if the web server is configured correctly.
• B. Traceroute can determine if each of the reachable routers between your computer and the web server are responsive.
• C. Traceroute can determine if the server that the web service is running on has a firewall.
• D. Traceroute can determine if the DNS server is configured correctly.

How can an OS X system automatically connect to a Wi-Fi network?

• A. The Activity Monitor application is used to monitor open processes and applications.
• B. 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.
• C. 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.
• 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.
