Module 1 Summary & Common Pitfalls

Subnetting speed and accuracy is the highest-leverage skill in this entire module — it resurfaces constantly in later domains.
Don't confuse ULA (IPv6 private addressing) with link-local — they serve different purposes and use different address ranges.
Remember IPv6 has no broadcast; multicast fully replaces that function.
Duplex mismatch causes degraded performance on a link that's still technically up; speed mismatch usually prevents the link from coming up at all — these are different failure signatures, frequently confused.
Know the practical difference between a VM and a container conceptually, even without needing deep virtualization administration skills for this exam.
