An enterprise is working with a third party and needs to allow access between the internal networks of both parties for a secure file migration. The solution needs to ensure encryption is applied to all traffic that is traversing the networks. Which of the following solutions should most likely be implemented?

EAP, or Extensible Authentication Protocol, is primarily used for network access authentication rather than encryption of data in transit. While it facilitates secure authentication, it does not provide the encryption of all traffic between networks, making it unsuitable for the requirements of secure file migration.

SD-WAN (Software-Defined Wide Area Network) is a technology that optimizes and manages WAN connections but does not inherently provide end-to-end encryption across all traffic. While it can incorporate secure protocols, it primarily focuses on performance and flexibility rather than direct encryption of data being transferred between networks.

TLS (Transport Layer Security) is a protocol that secures data transmitted over networks by encrypting the data at the application layer. While it is effective for securing data in transit, it is not designed for securing all traffic at the network layer like IPSec does, limiting its effectiveness when multiple types of traffic and networks are involved.
