A Linux administrator updates the DNS record for the company using:
cat /etc/bind/db.abc.com
The revised partial zone file is as follows:
ns1 IN A 192.168.40.251
ns2 IN A 192.168.40.252
www IN A 192.168.30.30
When the administrator attempts to resolve www.abc.com to its IP address, the domain name still points to its old IP mapping:
nslookup www.abc.com
Server: 192.168.40.251
Address: 192.168.40.251#53
Non-authoritative answer:
Name: www.abc.com
Address: 199.168.20.81
Which of the following should the administrator execute to retrieve the updated IP mapping?
