Hi All,
My company has two sites in to 2 different locations (plz see the
diagram from picture in the link) that are
connected via high speed link at the core layer  in each site I've 1
DMZ , the network team wants to connect the DMZ switches in both sites
for better performance and "security" - the link under investigation
is shown in red in the picture -   via high speed link without passing
at all by the core network layer, as they say that will aid more in
the replication between server A and backup server A in the DMZs and
also this will help if any of the 2 firewalls had failure to access
both DMZs from any firewall.
 Is that better from security point of view?

appreciating your great help and advice
thanks alot

Regards,
Nad
