The correct answer is B. Change the DNS entries for the Delivery Controllers to the new IP addresses.. Updating DNS entries for Delivery Controllers is the most scalable solution because VDAs resolve controllers by name, so a single DNS change propagates to all 2000 machines automatically.
Question
Scenario: Due to changes in the network infrastructure, the IP addresses of the Delivery Controllers will be changing. There are 2000 Desktop OS machines in the environment. What should a Citrix Administrator do to reduce the impact of the IP address changes on the environment?
Options
- AUpdate the beacons in StoreFront to reflect the updated IP addresses.
- BChange the DNS entries for the Delivery Controllers to the new IP addresses.
- CRun the Provisioning Services Configuration Wizard and update the IP addresses of the Delivery
- DRemove the Delivery Controller from the site, change the host file entries, and add the Delivery

Why each option
Updating DNS entries for Delivery Controllers is the most scalable solution because VDAs resolve controllers by name, so a single DNS change propagates to all 2000 machines automatically.
StoreFront beacons determine whether a client is on an internal or external network for routing purposes and are unrelated to VDA-to-Delivery Controller registration.
VDAs register with Delivery Controllers using DNS hostnames rather than hard-coded IP addresses. By updating the DNS A records to point to the new IP addresses, all 2000 Desktop OS machines automatically resolve the correct controller without any per-machine reconfiguration, minimizing administrative impact across the environment.
The Provisioning Services Configuration Wizard configures PVS streaming server settings and does not manage Delivery Controller IP address registration for VDAs.
Removing and re-adding the Delivery Controller combined with host file edits would require manual changes on all 2000 machines and does not scale to a large environment.
