Free Juniper JN0-683 Actual Exam Questions - Question 1 Discussion
scenario? (Choose two.)
Probably B and C here. eBGP in an underlay fabric often uses loopbacks for peering, so you don’t always need an IGP running just for adjacency—making B plausible. Also, the standard leaf-spine design means each leaf peers with every spine (C), not leaf-to-leaf, so D doesn’t fit. A seems off because the whole point of underlay fabrics is to simplify and avoid extra protocols if possible.
A imo, because eBGP normally needs some IGP or static routes for adjacency since it’s between different ASes and routers need to know how to reach each other. D doesn’t fit since leaf-to-leaf peering isn’t typical in underlay fabrics. C might be true but less of a given than A for sure. So A and D are less likely, making B and C the better picks, but I’d say A is definitely a factor to consider in an E8GP setup.
Makes sense to rule out D since leaf-to-leaf peering is not standard in underlay fabrics. So, B and C seem solid choices here.
B, C. E8GP peering doesn’t need an IGP for adjacency, and leaf nodes usually peer with all spine nodes in the fabric. D doesn’t feel right since leaf-to-leaf isn’t typical here.
