A user will be traveling with a smartphone that contains confidential information. Which of the following should be disabled? (Select TWO).

Disabling the keyboard would render the smartphone unusable for input and does not enhance security against external wireless threats while traveling.

Disabling speakers prevents audio output but offers no protection against unauthorized access to confidential information or external connectivity exploits.

Smartphones do not typically use a mouse for primary interaction, so disabling it would be irrelevant to securing confidential information on the device.

Disabling Bluetooth prevents unauthorized pairing with unknown devices and mitigates risks such as bluejacking or bluesnarfing, which could potentially expose confidential information or inject malware during travel.

Disabling NFC (Near Field Communication) prevents accidental or malicious data transfers and contactless payments without explicit user consent. This reduces the risk of 'skimming' or unintended data exchange with nearby devices in crowded environments.
