To prevent other devices on the network from accessing a laptop using public WiFi, which two solutions would be most effective?

A host-based firewall is an effective solution for preventing other devices on the network from accessing a laptop when using public WiFi. This type of firewall is installed directly on the individual device and acts as a barrier that controls incoming and outgoing network traffic based on predetermined security rules. By configuring the host-based firewall, you can block unwanted connections from other devices on the same public network, enhancing the security of the laptop against potential threats and unauthorized access.

A Trusted Platform Module (TPM) primarily provides hardware-based security functions, such as secure cryptographic key generation and storage, but does not directly control network access or visibility between devices on a network. A Data Loss Prevention (DLP) solution is focused on protecting sensitive data from being accessed or transmitted outside the organization's control, rather than managing device access on a public network. A VPN (Virtual Private Network) does help secure data transmissions over untrusted public networks by encrypting the traffic, but it does not directly prevent other devices on that network from accessing the laptop itself.
