Which GSLB method should the architect utilize to meet the design requirements?

Scenario: A Citrix Architect and a team of Workspacelab members met to discuss a Citrix ADC design project.

They captured the following requirements from this design discussion:

• All three (3) Workspacelab sites (DC, NDR, and DR) will have similar Citrix ADC configurations and design.

• The external Citrix ADC MPX appliances will have Global Server Load Balancing (GSLB) configured and deployed in Active/Active mode.

• ADNS service should be configured on the Citrix ADC to make it authoritative for domain nsg.workspaceIab.com.

• In GSLB deployment, the DNS resolution should be performed to connect the user to the site with least network latency.

• On the internal Citrix ADC, load balancing for StoreFront services, Citrix XML services, and Citrix Director services must be configured.

• On the external Citrix ADC, the Gateway virtual server must be configured in ICA proxy mode.

Which GSLB method should the architect utilize to meet the design requirements?
A . Dynamic RTT
B . Static Proximity
