Citrix Gateway 13 Administration — Question 16

Scenario: A Citrix Administrator is managing a NetScaler SDX running eight NetScaler instances. The administrator first needs to upgrade the firmware on the instances. However, the administrator is concerned that it needs to be done all at once.
What upgrading flexibility does SDX provide in this scenario?

Answer options

• A. The NetScaler instance can be upgraded at the SDX management level, allowing all instances to be upgraded at once.
• B. The NetScaler instances have to be upgraded at the same time.
• C. The NetScaler instance can be upgraded on an individual basis, allowing all instances to run different firmware versions.
• D. It is NOT possible to upgrade the NetScaler instances to different firmware versions.

Correct answer: A

Explanation

The correct answer is A because SDX allows upgrades at the management level, meaning all instances can be upgraded simultaneously if desired. Option B is incorrect as it suggests simultaneous upgrades are mandatory, which is not the case. Option C is also wrong because it implies that upgrades can occur individually, but it does not reflect the management-level upgrade capability. Option D is false since SDX does allow for different firmware versions across instances.
