Citrix Access Control Administration — Question 100

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?

Answer options

• A. The Citrix ADC instances must be upgraded simultaneously.
• B. The Citrix ADC instances can be upgraded on an individual basis, allowing all instances to run independent firmware versions.
• C. The Citrix ADC instances can be upgraded from the lights out management (LOM) port and Citrix Cloud services to different firmware versions.
• D. The Citrix ADC instances can be upgraded at the SDX management level, allowing all instances to be upgraded simultaneously.

Correct answer: B

Explanation

The correct answer is B because SDX allows each Citrix ADC instance to be upgraded independently, meaning they can run different firmware versions without affecting each other. Options A and D incorrectly suggest simultaneous upgrades, which are not required. Option C, while mentioning an upgrade method, does not address the capability of individual firmware version management.
