Which of the following physical security controls can prevent laptops from being stolen?

Encryption protects the data on a laptop if it is stolen, but it does not prevent the physical theft of the device itself.

LoJack for Laptops is a software-based service that helps recover a stolen laptop and remotely delete data, but it does not prevent the initial physical theft.

Multifactor authentication protects access to the data or system on a laptop, but it does not prevent someone from physically taking the device.

An equipment lock, such as a Kensington lock, physically tethers a laptop to a desk or other stationary object, making it difficult for an unauthorized person to remove and steal the device. This provides a direct physical deterrent against theft.

Bollards are sturdy posts used to prevent vehicle access or protect buildings, not individual laptops from being stolen.
