How can an administrator meet the needs of multiple newly acquired companies by providing separate VPN access, load balancing, and throughput on a single hardware device?

• A. Purchase a CPX for each
• B. Install XenServer and configure a Citrix ADC VPX 3000 for each
• C. Purchase a Citrix ADC MPX appliance for each
• D. Purchase a Citrix ADC SDX appliance, and configure a Citrix ADC instance for each

Answer: (D)

The capability being tested is multi-tenant virtualization on a single Citrix ADC hardware device. Citrix ADC SDX turns one physical box into a platform that runs multiple independent ADC instances, each with its own allocated CPU/memory, network interfaces, and VIPs. Each instance behaves like its own dedicated appliance, so you can assign separate VPN configurations, separate load-balancing rules, and distinct throughput for each tenant. This lets several newly acquired companies sit on the same hardware while staying isolated from one another, yet managed from a single device, which reduces hardware footprint and simplifies administration. Other approaches don’t fit as neatly. A CPX is software-based and would require separate host environments for each tenant, which doesn’t leverage a single hardware device to provide isolated, per-tenant resources. An MPX appliance is a single, non-multi-tenant hardware instance, so you wouldn’t get independent per-tenant VPN/LB/throughput within one box. Using virtualization with XenServer and VPX could host multiple instances, but it adds complexity and isn’t as tightly integrated for guaranteed per-tenant isolation on one device as the SDX multi-tenant architecture.
