Which practice is recommended to ensure that management changes are always made on the Primary NetScaler in a High Availability pair?

• A. Connect to both NetScalers to see which one is the Primary.
• B. Enable Management Access to a SNIP.
• C. Enable Management Access on the Cluster IP (CLIP) address.
• D. Connect to the shared HA NSIP.

Answer: (B)

When you’re working in a High Availability pair, you want to make changes on the device that is currently active (the Primary). Directing management traffic through a SNIP provides a stable path for admin sessions that is tied to the active unit, so your configuration changes end up on the Primary regardless of failover state. Enabling Management Access on a SNIP ensures management connections go through that interface, which is executed by the node currently handling traffic for that SNIP, effectively targeting the Primary. Connecting to both NetScalers to see which is Primary relies on manual checks and can lead to mistakes. Using the Cluster IP for management doesn’t guarantee you reach the Primary, since that address is used for internal cluster purposes and can be less predictable for admin sessions. The shared HA NSIP can complicate routing of management traffic and isn’t as reliable for consistently hitting the active device.
