• Question 38:

  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
