Which of the following should Matt, a security administrator, include when encrypting smartphones? (Select TWO).

Steganography hides data within image files and is a data-hiding technique, not an encryption control applied to device storage.

Internal memory is the primary storage location for the operating system, applications, credentials, and user data on a smartphone, and must be encrypted to prevent access if the device is lost or stolen.

Master boot records are a concept from traditional PC hard drives and are not a relevant storage component in the architecture of modern smartphones.

Removable memory cards such as microSD cards can store photos, documents, and app data outside the device's built-in encrypted storage, so they must also be encrypted independently to ensure no data is exposed when the card is removed from the device.

Public keys are cryptographic values used in asymmetric operations and are not a storage location that needs to be included in a device encryption scheme.
