Device Roles for RA-guard, devices can have different roles:
• Host (default): can only receive RA from valid routers, no RS will be received
• Router: can receive RS and send RA
• Monitor: receive valid and rogue RA and all RS
• Switch: RA are trusted and flooded to synchronize states

given answer is incorrect
- Receives router advertisements from valid routers, and no router solicitation are received = host
- Receives router solicitation and sends router advertisements = router
- Receives valid and rogue router advertisements and all router solicitation = monitor
- Received router advertisements are trusted and are flooded to synchronize states = switch

Important to consider is the direction. In this case we are talking about the devices itself and not about the configuration of the Switch-Port.
1: host
2: router
3: monitor
4: switch
For RA-guard, devices can have different roles
• Host (default): can only receive RA from valid routers, no RS will be received
• Router: can receive RS and send RA
• Monitor: receive valid and rogue RA and all RS
• Switch: RA are trusted and flooded to synchronize states
I Think tha is the right order
Host Receives router advertisements from valid routers and no router solicitation are received
Router- Receives router solicitation and sends router advertisements
Switch Receives valid and rogue router advertisements and all router solicitation
Monitor Received router advertisements are trusted and are flooded to synchronize states
