When considering the design of the E-Commerce topology which of the following are true?.

A.
One-armed SLB design with multiple security contexts removes the need for a separate firewall in the core layer

B.
Two-firewall-layer SLB design considers the aggregation and access layers to be trusted zones, requiring no security between the web, application, and database
zones

C.
One-armed SLB design with two firewall layers ensures that non load-balanced traffic still traverses the ACE so that the health and performance of the servers is
still being monitored

D.
In all cases there will be configuration requirements for direct access to any servers or for non load-balanced sessions initiated by the servers
