Which Citrix ADC-owned IP address is used by default for outbound NTP traffic from the appliance?

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

Answer: (B)

The main idea is that outbound system services on a Citrix ADC use the NetScaler IP (NSIP) as the source by default. NTP is a system clock synchronization service, so its traffic is treated as management/control-plane traffic. The NSIP is the IP the appliance uses for such internal operations, making it the source for outbound NTP packets. The other IP types serve different purposes: the Subnet IP is used as the source for most data-plane outbound connections to servers in a subnet, the VIP is the address clients connect to for services, and the Clip is an additional outbound IP used in some configurations but not the default source for NTP.
