In a GSLB environment using a proxy for site persistence, which IP address is used as the source for outbound traffic?

• A. Subnet IP (SNIP)
• B. Client IP
• C. VIP
• D. LDNS IP

Answer: (A)

In this GSLB setup, the outbound traffic from the Citrix ADC, including traffic routed through a proxy for site persistence, originates from the Subnet IP (SNIP). The SNIP is the address the appliance uses for all data-plane connections leaving the unit, so responses from the remote site come back along the same path. VIP is the address clients connect to, but it’s not used as the source for outbound traffic. The LDNS IP is only for DNS resolution, not data-plane traffic, and the NSIP is the management/control plane address. Using SNIP ensures consistent routing and correct persistence behavior across sites.
