the answer in the solutionbox is wrong Set-DNSServerRRL -mode Enable #enables RRL if enabled: Add-DnsServerResponseRateLimitingExceptionlist # create List and adds ServerInterface like "EQ,10.0.0.0" you need to run only second cmd if RRL always enabled

"You enable Response Rate Limiting on Server1." - You already enabled it - why would you enable it again? You'd need to create the subnet item and then add the subnet item to the exception list.

The Set-DnsServerResponseRateLimiting cmdlet enables Response Rate Limiting (RRL) on a Windows DNS server. https://docs.microsoft.com/en-us/powershell/module/dnsserver/set-dnsserverresponseratelimiting?view=win10-ps

first you define the subnet with Add-DnsServerClientSubnet -Name "nameofsubnet" -IPv4Subnet 10.0.0.0/16 for example then you can use it in the Add-DnsServerResponseRateLimitingExceptionlist command

I think that the answer area is correct The rate limiting is active you must add before the subnet and then settting rate limiting https://docs.microsoft.com/en-us/powershell/module/dnsserver/set-dnsserverresponseratelimitingexceptionlist?view=win10-ps https://docs.microsoft.com/en-us/powershell/module/dnsserver/add-dnsserverclientsubnet?view=win10-ps

I think you're right. It says the first command will enable it with the defaults, and then you can use the second command to change them. Also https://docs.microsoft.com/en-us/powershell/module/dnsserver/set-dnsserverresponseratelimiting?view=win10-ps states that "The Set-DnsServerResponseRateLimiting cmdlet enables Response Rate Limiting (RRL) on a Windows DNS server." and https://docs.microsoft.com/en-us/powershell/module/dnsserver/add-dnsserverresponseratelimitingexceptionlist?view=win10-ps states that "The Add-DnsServerResponseRateLimiting cmdlet adds a Response Rate Limiting (RRL) exception list on the DNS server. The RRL exception list indicates that responses to queries for specified Fully Qualified Domain Names (FQDNs), queries originating from specified client subnets, queries received on specified server interfaces, or any combination of these values, are exempt from RRL."

No to Set-DnsServerResponseRateLimiting. Read the question - RRL is already enabled
