A BIND server should be upgraded to use TSIG. Which configuration parameters should be added, if
the server should use the algorithm hmac-md5 and the key skrKc4DoTzi/tAkllPi7JZA== ?
A.
TSIG server.example.com.
algorithm hmac-md5;
secret “skrKc4DoTzi/tAkllPi7JZA==”;
};
B.
key server.example.com. {
algorithm hmac-md5;
secret skrKc4DoTzi/tAkllPi7JZA==;
};
C.
key server.example.com. {
algorithm hmac-md5;
secret “skrKc4DoTzi/tAkllPi7JZA==”;
};
D.
key server.example.com. {
algorithm=hmac-md5;
secret=”skrKc4DoTzi/tAkllPi7JZA==”;
};
E.
key server.example.com. {
algorithm hmac-md5
secret “skrKc4DoTzi/tAkI1Pi7JZA==”
};
Explanation:
Insert into /etc/bind/named.conf.local of master DNS and all slave DNS.In the allow-transfer
statement add the key keyword instead of IPs.
