Free Juniper JN0-460 Actual Exam Questions - Question 6 Discussion

C seems too generic and misses the 5-stage detail, so D fits better here.

D. The key here is the 5-stage Clos, which means more spine layers beyond the usual 3-stage setup. That extra hierarchy is exactly what D describes, making it the best fit.

Makes sense to rule out A and B since they’re about protocols, not architecture. D fits best as it clearly describes the 5-stage Clos setup with extra spine layers. Definitely D.

It’s D. The key here is the mention of extending the classic 3-stage Clos by adding spine and super-spine layers, which matches what a 5-stage design is about for bigger campus networks.

Option D makes the most sense here, since a 5-stage Clos network is basically an enhanced version of the classic 3-stage design, adding more spine layers for better scalability in large campus setups. Option C just refers to the basic 3-layer hierarchy and doesn’t capture the added complexity or scalability aspect that the 5-stage model brings. The other options don’t really match a hierarchical architecture either, so D stands out as the best fit.

C imo, since the question highlights a hierarchical design and 5-stage Clos networks are basically an evolution of the 3-stage model, which is standard in campus fabrics. While D talks about spine and super-spine layers, C’s mention of distribution, core, and access layers fits the classic hierarchical setup that Clos networks build upon. A and B are too specific to protocols or tunneling, which isn’t what the 5-stage Clos is about structurally.

D imo, because it clearly mentions extending 3-stage Clos with extra layers for scale.

D sounds right, the 5-stage Clos adds spine and super-spine layers for bigger setups. The others don’t fit the description as well.
