JNCIP-DC: Juniper Networks Certified Professional – Data Center (2023) — Question 39

Which two statements are correct about a spine and leaf-based IP fabric? (Choose two.)

Answer options

• A. Clos networks demonstrate good scaling features.
• B. Traffic is diverted within the fabric when a device or link fails.
• C. There is no need for redundancy at the server level.
• D. Leaf switches broadcast frames to all other leaf devices.

Correct answer: B, D

Explanation

Option B is correct because in a spine and leaf architecture, traffic is indeed rerouted to maintain connectivity during a failure. Option D is also correct as leaf switches do broadcast frames to all other leaf devices to ensure they reach their destination. Options A and C are incorrect; Clos networks do scale well, but redundancy at the server level may still be necessary for high availability.
