Which design decision must the architect make to meet the design requirements above?

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?
A . Mac Based Routing must be configured on the External Citrix ADC
B . Interface 0/1 must be used for DNS traffic
C . The SNIP of the external Citrix ADC must be configured as default gateway on the back-
end servers
D . ADNS service must be used with IPv6 address
E . The SNIP of the internal Citrix ADC must be configured as the default gateway on the back-end servers.
