Which topology meets this requirement?
A. Cascade
B. Flat SAN
C. Core-edge
D. Ring
Correct Answer: C

Explanation/Reference:
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
