Zero DHCP? How IPv6 SLAAC actually works on the CCNA
Testing your IPv6 fundamentals today. Drop your guess in the comments before the timer hits zero!
The question
With no DHCP server, which message provides an IPv6 host with its network prefix during SLAAC?
The answer
A Router Advertisement (RA)
Routers send Router Advertisements carrying the prefix and default gateway info. Don't fall for B — the host sends Router Solicitations, it doesn't get prefixes from them. Follow for tomorrow's rep.
Exam tip
Read what the question is actually asking before looking at the options. The wrong answers here are ones candidates genuinely pick — each is true of something adjacent, just not of what was asked.
