Your network contains an Active Directory Domain Services (AD DS) domain. The domain contains a user named User1. User1 is a member of a group named Group1 and is in an organizational unit (OL)} named OU1. The domain has minimum password lengths configured as shown in the following table. 
Doesn't the PSO with lowest precedence always override the domain policy if it's linked via Group1? Unless User1 has another direct PSO or a higher-precedence one applies somehow, looks like 7 chars is enforced. Someone correct me if I'm missing a nuance with OU-level policies here.
Pretty sure it's A here. JIT VM access specifically reduces the window that admin ports are open, which is what Azure exams usually focus on for security. D trips people up since Bastion hides public RDP, but it's not as granular for port lockdown. Disagree?
I get why people pick D, but for this you want to limit port exposure as much as possible, so A (JIT VM access) is better. Pretty sure Azure pushes JIT in these scenarios. Correct me if I'm missing some corner case.
