Switching from network admin to architecture work, the ENSLD multicast and QoS design questions helped me see why networks are built a certain way, not just how.
Coming from ops, the design-first mindset in 300-420 was a real shift. Practicing redistribution and campus hierarchy scenarios here made that transition click.
Solid resource for ENSLD prep, especially the WAN design and automation sections. A few questions felt more surface-level than the real exam, so treat this as a foundation and layer in other materials. Overall it moved my confidence up noticeably going into test day.
