To scale bandwidth and offload SSL, which Citrix ADC platform is recommended as the primary hardware appliance?

• A. CPX
• B. VPX
• C. SDX
• D. MPX

Answer: (D)

When you need to push a lot of traffic and offload the TLS work from your servers, you want hardware-accelerated processing at the edge. The MPX platform is the high-end, purpose-built Citrix ADC hardware appliance designed for exactly this: large-scale throughput and dedicated SSL offload hardware. With SSL/TLS offload implemented in the appliance, encryption work is handled in hardware, freeing backend servers to focus on application processing and enabling much higher overall bandwidth.

Virtualized and containerized options like VPX and CPX run on standard servers or in containers, so their SSL processing relies on the host CPU, which typically doesn’t match the performance of hardware-accelerated MPX. SDX can host multiple VPX instances on one hardware chassis, but for the primary goal of maximum bandwidth and SSL offload, MPX remains the recommended single, primary hardware appliance.
