SY0-301 · Question #97

Which of the following can be used on a smartphone to BEST protect against sensitive data loss if the device is stolen? (Select TWO).

The correct answer is C. Remote wipe F. Device encryption. If a smartphone is stolen, remote wipe destroys the data remotely and device encryption ensures data is unreadable without the decryption key, providing the strongest protections against sensitive data loss.

Why each option

If a smartphone is stolen, remote wipe destroys the data remotely and device encryption ensures data is unreadable without the decryption key, providing the strongest protections against sensitive data loss.

ATethering

Tethering shares the device's internet connection with other devices and provides no protection against data loss on a stolen device.

BScreen lock PIN

A screen lock PIN prevents casual access but does not protect data if the device storage is physically extracted or a bypass is used.

CRemote wipeCorrect

Remote wipe allows an administrator or owner to send a command that erases all data on the stolen device, directly preventing unauthorized access to sensitive information even when physical possession is lost.

DEmail password

An email password only protects the email account and does not secure other sensitive data stored on the device.

EGPS tracking

GPS tracking helps locate the device but does not prevent an attacker from accessing or copying data once they have physical possession.

FDevice encryptionCorrect

Device encryption renders all stored data unreadable to anyone without the correct decryption credentials, so even if the device is physically accessed or the storage is removed, the data cannot be read.
