2. What are two ways that iOS differs from Android? (Choose two.)

  • iOS uses an All Apps button whereas Android uses a Home button.
  • iOS has a physical Home button, but Android uses navigation icons.
  • In iOS, the icon for an app represents the app itself. Deleting the icon in iOS deletes the app. In Android, the icon on the Home screen is a shortcut to the app.
  • In iOS, apps can only appear on screens, whereas in Android, apps can appear on screens and in folders.
  • In iOS, folders are created by dragging one app on top of another app, but in Android folders must be created from the home screen menu.

Explanation: Apple iOS devices have a physical Home button that has many uses. One of the uses of the Home button is navigation between screens. Android uses navigation icons instead of a physical Home button. In addition, much like a Windows OS, apps in Android are represented by icons that are shortcuts to the actual app. In iOS, the icons are the apps. Deleting an icon in Android deletes only the shortcut. However, the entire app is deleted from an iOS device when its icon is deleted.

3. What are two purposes of the passcode lock feature on mobile devices? (Choose two.)

  • Members of the group have read and execute access to the file.
  • Other people have read and execute access to the file.
  • Group members are able to modify the file.
  • The user is able to read and modify the file.
  • Other people have no access to the file.

Explanation: Read, write, and execute permissions are assigned to each file. The permissions are listed in groups of three. The first group of three permissions references users, the second references group members, and the third references others. The first position of each of the three permissions is the R or read permission, the second is the W or write permission, and the third is the X or execute permission. If any position has a dash, the associated group does not have permission for that category. In this case, the user hasread and write access (rw-). Group members haveread and execute access (r-x). Other people haveexecute only access (–x).

8. What is a good source for safely downloading Android apps?
