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 NetScaler MPX appliances deployed in the DMZ and internal network.
• High Availability will be accessible for each NetScaler MPX
• The external NetScaler MPX appliance will be deployed in multi-arm mode.
• The internal NetScaler 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 NetScaler configurations and design.

How many NetScaler MPX appliances should the architect deploy at each site to meet the design requirements above?

A. 4
