Scenario: Based on a discussion between a Citrix Architect and a team of Workspacelab members, the MPX Logical layout for Workspacelab has been created across three (3) sites.
The requirements captured during the design discussion held for a NetScaler design project are as follows:
* Two (2) pairs of Citrix ADC MPX appliances deployed in the DMZ and internal network.
* High Availability will be accessible for each Citrix ADC MPX
* The external Citrix ADC MPX appliance will be deployed in multi-arm mode.
* The internal Citrix ADC MPX will be deployed in single-arm mode wherein it will be connected to Cisco ACI Fabric.
* All three (3) Workspacelab sites: Dc, NDR and DR, will have similar Citrix ADC configurations and design.
How many Citrix ADC MPX appliances should the architect deploy at each site to meet the design requirements above?
