A security analysis at The Potomac Canal Company recommends installing an IDS appliance anda firewall appliance. These appliances should connect directly into a Layer 3 switch. A loadbalancer and SSL termination have also been recommended.Potomac’s management haveexpressed concern over the cost. You suggest using integrated blades. What is one advantage and one disadvantage of yourdesign proposal？ （）

• A、 The data center would need several devices to achieve its goal.
• B、 Increased usage of standalone devices is cost-effective.
• C、 Using integrated blades would only require two devices.
• D、 Putting all security devices in a single chassis provides a single point of failure.
