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.
They captured the following requirements during the design discussion held for a Citrix ADC design project:
* All three (3) Workspacelab sites (DC NDR and DR) will have similar Citrix ADC configurations and design
* Both external and internal Citrix ADC MPX appliances will have Global Server Load Balancing (GSLB) configured and deployed in Active/Passive mode
* GSLB should resolve both A and AAA DNS queries.
* In the GSLB deployment the NDR site will act as backup for the DC site, whereas the DR site will act as backup for the NDR site
* When the external Citrix ADC replies to DNS traffic coming in through Cisco Firepower IPS the replies should be sent back through the same path
* On the internal Citrix ADC. both front-end VIP and back-end SNIP will be part of the same subnet
* USIP is configured on the DMZ Citrix ADC appliances
* The external Citrix ADC will act as default gateway for back-end servers.
* All three (3) sites (DC, NDR, and DR) will have two (2) links to the Internet from different service providers configured in Active/Standby mode Which design decision must the architect make to meet the design requirements above?
