What learners say

Feedback from people who studied 300-420 on NerdExam.

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.

BGP design finally clicked. Cleared ENSLD on my first attempt.

lucia.coNetwork engineer

The OSPF and BGP routing design topology questions are the hardest part of 300-420 - and NerdExam leans into those heavily. I failed my first attempt partly because I underestimated the depth of routing design. Second attempt passed after drilling those scenarios here.

Sam P.Mid-level network engineer

The SD-WAN and SD-Access design scenarios here push you to think architecturally, which is exactly what 300-420 tests.

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.
