Refer to the exhibit. The web servers WS_1 and WS_2 need to be accessed by external and internal users. For security reasons， the servers should not communicate with each other，
although they are located on the same subnet. The servers do need， however， to communicate with a database server located in the inside network.
What configuration will isolate the servers from each other？ （）
A. The switch ports 3/1 and 3/2 will be defined as secondary VLAN community ports. The ports connecting to the two firewalls will be defined as primary VLAN promiscuous ports.
