Scenario: A Citrix Administrator is managing a Citrix ADC SDX running eight Citrix ADC instances. The administrator needs to upgrade the firmware on the instances. However, the administrator is concerned that it needs to be done simultaneously.
What upgrading flexibility does SDX provide in this scenario?
Citrix ADC SDX allows the flexibility to upgrade Citrix ADC instances on an individual basis. This means each instance can run independent firmware versions, giving administrators the flexibility to upgrade instances according to their needs and avoiding the necessity of simultaneous updates.
The admin is Concerned that he has to update simultanously, so he do not want to do this. Does not matter of he can do it, so imho correct answer is B, he can do it on an independent Basis aswell.
With the SDX, the administrator can perform firmware upgrades at the SDX management level. This means that all instances hosted on the SDX appliance can be upgraded simultaneously, ensuring consistency across the environment.
