Citrix ADC 13 Advanced Topics – Security, Management and Optimization — Question 99

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

Correct answer: C

Explanation

The correct answer is C because the Citrix ADC instances can indeed be upgraded independently, allowing for different firmware versions on each instance. Option A is incorrect as it states that upgrades must occur simultaneously, which is not the case. Option B is misleading as it focuses on upgrading methods rather than the flexibility of independent upgrades, while D incorrectly suggests that all instances can only be upgraded at the same time.
