Quick CCNP drill on Private VLAN architecture and secondary VLAN behavior. Drop your answer in the comments before the timer runs out!
The question
In a Private VLAN, which secondary VLAN type prevents member ports from communicating with each other?
The answer
B Isolated VLAN
Isolated ports can only talk upstream to promiscuous ports, never each other. Don't get tripped up: promiscuous is a port mode, not a secondary VLAN type. 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.
