[单选题]A BIG-IP device is configured with both an internal external and two Corporate VLANs. The virtual server has SNAT enabled and is set to listen on all VLANs Auto Last Hop is disabled. The Corporate users are on10.0.0.0./24 and 172.16.0.0/12. The BIG-IP has a Self-IP on the 1.0.0.0.0./24 subnet. Internet users are able to access the virtual server. Only some of the Corporate users are able to connect to the virtual server A BIG-IP Administrator performs a tcpdump on the BIG- IP and verifies that traffic is arriving from users in 10.0.0.0/24.
What should the BIG-IP Administrator do to correct this behaviour?
A.Disable the server on the internal VLAN
B.Add a static route for the 172.16.0.0/12 subnet
C.Change the default route to point to the extra firewall
D.Modify the default route of the servers to point to the BIG-IP device
