Citrix ADC 13 Administrator — Question 45

A Citrix Administrator is configuring a NetScaler high availability (HA) pair and needs to ensure that one Net Scaler is UP and primary at all times to ensure the business websites are always available.
What does the administrator need to do to ensure that the NetScalers still handle web traffic in the event that both nodes become unavailable or fail a health check?

Answer options

• A. Configure HA Fail-safe mode on the Primary NetScaler only.
• B. Disable HA Fail-safe mode on the Primary NetScaler only.
• C. Disable HA Fail-safe mode on the Secondary NetScaler.
• D. Configure HA Fail-safe mode on each NetScaler independently.

Correct answer: D

Explanation

Configuring HA Fail-safe mode on each NetScaler independently allows for continued handling of web traffic even if both nodes fail. If only one NetScaler had HA Fail-safe mode configured, the other would not be able to pick up the traffic if the primary fails, leading to downtime. Therefore, options A, B, and C would not provide the necessary redundancy.
