What is the effect of enabling tagging on all interfaces in a shared Citrix SDX environment?

• A. Enables MBF mode
• B. Disables VLAN tagging
• C. Ensures correct VLAN tagging and traffic flow
• D. Reduces CPU usage

Answer: (C)

In a shared Citrix SDX environment, enabling tagging on all interfaces ensures that each frame carries its VLAN identifier end-to-end. This lets the SDX fabric demultiplex traffic correctly, routing each VLAN’s frames to the appropriate tenant’s virtual appliance or service partition. With tags preserved on every link, traffic remains isolated by VLAN and reaches the right destination, preventing cross-tenant leakage and ensuring policies and routing apply properly. If tagging isn’t consistently enabled, untagged frames or mismatched VLAN contexts can cause misrouted traffic or isolation issues. The other options don’t describe this effect: MBF mode is a different feature set, disabling VLAN tagging would break isolation, and tagging does not inherently reduce CPU usage.
