EMC Proven Professional – Technology Architect — Question 16

Which mechanism in a Fibre Channel SAN prevents illegitimate host connections by rejecting WWPN logins?

Answer options

• A. Port binding
• B. Fabric binding
• C. Persistent port locking
• D. Port-type locking

Correct answer: A

Explanation

Port binding is the correct answer because it restricts access to specific WWPNs, ensuring that only authorized hosts can connect. Fabric binding and persistent port locking do not specifically address WWPN login rejection, while port-type locking pertains to the type of device connected rather than authentication verification.
