An organization with multiple geographic locations has invested in various internet circuits at each location, including MPLS, 4G/5G, broadband, and dial-up. An architect is configuring a solution that will allow locations to function consistently and leverage links based on specific criteria. Which of the following is the best solution for the architect to configure?

Unified Threat Management (UTM) focuses on providing comprehensive security features, such as firewall, intrusion detection, and antivirus capabilities in a single device. While UTM enhances security for network connections, it does not specifically address the optimization of multiple internet circuits or provide the intelligent traffic management that SD-WAN offers.

A Virtual Private Network (VPN) creates secure connections over the internet, allowing remote users or locations to securely access a private network. However, VPNs do not inherently provide the traffic management capabilities or the ability to leverage multiple internet connections effectively, which are essential for ensuring consistent performance across various sites.

Secure Access Service Edge (SASE) combines networking and security functions into a single cloud service. While it offers some capabilities that overlap with SD-WAN, such as secure connectivity, it is primarily focused on security services rather than the optimization of connections based on specific performance criteria across multiple internet links.
