Part 4 Flashcards
How does System Integrity Protection help ensure that macOS Catalina system resources remain secure?
System Integrity Protection prevents users and processes with administrator or root access from modifying core macOS Catalina items. Protected items include the /System, /bin, /sbin, and /usr folders, along with core macOS Catalina apps.
What are file system tags? Where can you find tags in the user interface?
File system tags are a type of metadata that allows you to quickly assign keywords, or “tags,” to any item. A user can customize the tag names and colors and can create multiple tags for a single file.
Which types of files are omitted from Time Machine backups?
Time Machine ignores temporary files, Spotlight indexes, items in the Trash, and anything that can be considered a cache.
What happens when you try to select an APFS volume as a Time Machine backup?
If you select a backup disk that’s formatted as APFS, FAT32, or any other file system besides HFS Plus, Time Machine offers to reformat it to the supported format of HFS Plus.
From which two sources does macOS allow you to open apps by default?
macOS allows you to open apps from the App Store and trusted developers. However, you can override this protection.
How does macOS Catalina identify 32-bit apps that won’t open?
The Finder displays a prohibitory symbol over the icon of any 32-bit app to indicate that the app won’t open in macOS Catalina.
How can Activity Monitor help you identify if a Mac has sufficient physical memory for the task?
Activity Monitor uses the Swap Used and Compressed memory statistics to display the historical memory use since the last startup. A low swap value is acceptable, but a high value would indicate that a Mac doesn’t have enough real memory to meet the app’s demands.
What is the default protocol macOS uses to get an IP address?
macOS uses Dynamic Host Configuration Protocol (DHCP) to automatically acquire preliminary TCP/IP configuration and to assign IPv4 addressing.
