A customer currently has a single fabric switch. They are planning to expand their fabric to a
total of five switches and connect not more between two switch and two switch hops. Which
topology meets this requirement?

A.
Cascade

B.
Flat SAN

C.
Core-edge

D.
Ring

Explanation:
Cascaded fabric
• Ability to connect SANs in diverse geographic locations
• Ease of scalability for increased server and storage connectivity
• Shared backup and management support
• Optimum local performance when communicating devices are connected to the same
switch in the cascaded fabric
• Cost efficiency due to the large number of switch ports available
• Support for local data access and occasional centralized data access

Ring fabric
• Modular design and ease of scalability by adding a switch and other devices
• Multiple paths for internal fabric resiliency
• Support for a mix of local data access and occasional centralized data access

Core-edge fabric (called core switches)
• Typically, a maximum of two hops between switches
• Equal, centralized access to devices in the core
• Increased fabric and switch redundancy with two or more switches in the core
• Full many-to-many connectivity with evenly distributed bandwidth
• Support for centralized and distributed data access needs
• Ability to designate an optimally located

Flat SAN
