Which Citrix ADC-owned IP address will send traffic from the Citrix ADC to NTP servers by default?

• A. Clip
• B. Vip
• C. Snip
• D. Nsip

Answer: (D)

The question tests how Citrix ADC chooses the source IP for outbound time synchronization traffic. When the unit reaches out to external NTP servers, it uses one of its own IPs as the source address for those UDP packets. By default, if no SNIP (Subnet IP) is configured to handle data-plane traffic, the appliance uses its NSIP (NetScaler IP) as the source for outbound requests like NTP. The NSIP is the management/control IP of the appliance and, in standard setups, will originate management-related and default outbound traffic unless you explicitly assign a SNIP to handle such traffic. If a SNIP is configured and in use, NTP requests would originate from that SNIP instead of the NSIP. So, the default source is the NSIP, with the SNIP taking over only when it’s configured for outbound traffic.
