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.
key server.example.com. { algorithm hmac-md5; secret skrKc4DoTzi/tAkllPi7JZA==; };

B.
key server.example.com. { algorithm hmac-md5 secret “skrKc4DoTzi/tAkI1Pi7JZA==” };

C.
key server.example.com. { algorithm hmac-md5; secret “skrKc4DoTzi/tAkllPi7JZA==”; };

D.
TSIG server.example.com. algorithm hmac-md5; secret “skrKc4DoTzi/tAkllPi7JZA==”; };

E.
key server.example.com. { algorithm=hmac-md5; secret=”skrKc4DoTzi/tAkllPi7JZA==”; };
