Explanation

EAP-TLS is the ideal choice because it provides enterprise-grade, certificate-based mutual authentication, meaning both the server and the client verify each other's identity. This creates a seamless yet highly secure experience for individual guests, as each user gets unique credentials rather than sharing a common password - perfectly balancing convenience and strong security for a luxury hotel environment.

Why the distractors are wrong:

• A (PSK): Pre-Shared Key uses a single password shared among all users, which is convenient but lacks individual accountability and is easy to compromise if the key leaks.
• B (Open Authentication): Requires no credentials at all, making it extremely convenient but completely insecure - unacceptable for a luxury hotel promising security.
• D (MAC Address Filtering): Only checks a device's hardware address, which can be easily spoofed, and is administratively burdensome - neither truly secure nor seamless.

Memory Tip: Think of EAP-TLS as a digital VIP keycard - just like a luxury hotel gives each guest their own room key rather than a master key shared by everyone, EAP-TLS gives each user their own certificate for secure, personalized access. When you see "individual + secure + seamless," think EAP-TLS.
