cache dns server
Current dns server default cache is 1 hour , should increase to 4 hour or 8 hour to improve performance dns ?
In my experience there's nothing that needs to be configured specific to your DNS server, but then again its a pretty vague question. When I stand up a new domain controller with integrated DNS role I don't do anything specific to DNS settings.
current client request more domain external as gmail.com should i want dns server as recure cache these domain external to reduce performance high. in dns server current this value MaxKBSize is 0 , should Set-DnsServerCache -MaxKBSize 20480 or higher ?
Hard to say really. I'd start by describing the environment and topology. Then also the problems you're trying to solve.
Looks typical where I'd tend to leave things set to default.
