You have a DNS server named Served that has a Server Core Installation on Windows
Server 2012 R2.
You need to view the time-to-live (TTL) value of a name server (NS) record that is cached by
the DNS Server service on Server1.
What should you run?
A.
Show-DNSServerCache
B.
nslookup.exe
C.
ipconfig.exe /displaydns
D.
dnscacheugc.exe
Explanation:
The Show-DNSServerCache shows all cached Domain Name System (DNS) server
resource records in the following format: Name, ResourceRecordData, Time-to-Live (TTL).
Confirmed
I think its C ,bc its core installation. You can test it on your pc .
c
it’s a DNS on a core installation, so A
You would be right if it wasn’t a DNS.
C is the CLIENT cache- Things that the server OS had to look up for itself as a client (like if you used IE to go to MS.com).
A
is the SERVER cache- things the DNS server program had to look up for clients.
sorry , its A
It’s A.
C is wrong format,it would be correct if it was ipconfig/displaydns.
actually that’s not true. ipconfig.exe /displaydns works fine, but it doesn’t return the ttl from the dns server cache but from the dns client. So answer is A.
with the cache it always shows what has been done with most commands especially with powershell
