Which type of zoning reduces the risk of WWPN spoofing on a Fibre Channel network?

Answer options

• A. Port-based
• B. WWPN-based
• C. Mixed
• D. eui-based

Correct answer: A

Explanation

Port-based zoning is effective in reducing the risk of WWPN spoofing because it restricts access based on physical ports rather than WWPNs, making it harder for unauthorized devices to impersonate legitimate ones. WWPN-based zoning, on the other hand, relies on the WWPN addresses, which can be spoofed. Mixed zoning combines both methods but doesn't eliminate the risk associated with WWPNs, while eui-based zoning is less common and may not provide the same level of security against spoofing.
