CompTIA Network+ (N10-008) — Question 168

Which of the following types of datacenter architectures will MOST likely be used in a large SDN and can be extended beyond the datacenter?

Answer options

• A. iSCSI
• B. FCoE
• C. Three-tiered network
• D. Spine and leaf
• E. Top-of-rack switching

Correct answer: D

Explanation

The Spine and Leaf architecture is designed for scalability and is ideal for large-scale Software-Defined Networking (SDN) environments, allowing for easy expansion. In contrast, iSCSI and FCoE are storage protocols, while the Three-tiered network and Top-of-rack switching do not provide the same level of scalability and flexibility necessary for large SDN implementations.
