Designing Cisco Data Center Infrastructure (DCID) — Question 120
A network consultant reviews the requirements for the Storage Area Network (SAN) design. The proposed solution must offer a very efficient port usage and eliminate the need for a separate physical layer of switches and their associated ISLs. The design is not expected to require future expansion.
Which SAN topology must be used to meet these requirements?
Answer options
- A. core-edge
- B. collapsed-core
- C. core-distribution-access
- D. edge-core-edge
Correct answer: B
Explanation
The collapsed-core topology is suitable as it combines the core and distribution layers into a single layer, optimizing port usage and reducing the need for additional switches. The other topologies, like core-edge and core-distribution-access, do not eliminate the need for separate layers, which does not align with the requirements stated.
