SG0-001 Question #265: Real Exam Question with Answer & Explanation
The correct answer is D. port authentication. In a shared Fibre Channel environment where central IT provides fabric, storage, and backup, but individual departments manage their own systems, controlling access to specific storage resources is paramount.
Storage Connectivity
Question
University IT provides shared Fibre Channel storage services. All storage subsystems and fibre channel switches are located in the secure campus datacenter. Each college and department provides their own systems and staff. Central IT provides fabric, storage and backup administration. Which security mechanism is most important in this Fibre Channel infrastructure?
Options
- AFCPAP
- Blink encryption
- Cswitch authentication
- Dport authentication
Explanation
In a shared Fibre Channel environment where central IT provides fabric, storage, and backup, but individual departments manage their own systems, controlling access to specific storage resources is paramount.
Common mistakes.
- A. FCPAP is a security protocol for authenticating entities connecting to the fabric, but it does not directly control granular host-to-storage access or resource segregation within the fabric.
- B. Link encryption protects data confidentiality in transit over the Fibre Channel link but does not provide access control or restrict which hosts can access specific storage resources.
- C. Switch authentication verifies the identity of Fibre Channel switches for fabric integrity and trust, but it does not manage host-level access to storage resources within the fabric.
Concept tested. Fibre Channel port access control
