What is the purpose of the predefined firewall rule called 'Zscaler proxy traffic'?

• A. Whitelist the IP addresses of Zscaler data centers
• B. Whitelist legacy on-prem proxy vendor's public IP addresses
• C. Configure failover between Zscaler data centers
• D. Implement a Layer 2 MAC header-based security group tag

Answer: (A)

The predefined firewall rule known as 'Zscaler proxy traffic' serves to whitelist the IP addresses of Zscaler's data centers. This is crucial because Zscaler operates a cloud-based security platform that routes user traffic through its data centers to provide secure internet access and other services. By allowing traffic from recognized and verified Zscaler IP addresses, organizations ensure that their network can communicate seamlessly with the Zscaler service, thereby facilitating secure and efficient proxy functions. This rule plays a foundational role in maintaining security while allowing necessary traffic, preventing unauthorized access, and enhancing the performance of services provided by Zscaler. The other options, while relevant in different contexts, do not accurately describe the primary function of the 'Zscaler proxy traffic' rule. For instance, whitelisting legacy on-prem proxy vendor's public IP addresses might be useful for organizations maintaining older systems but isn't the focus of this specific rule. Configuring failover settings is more about ensuring continuity and resilience of service, which isn't the intent of this rule. Implementing Layer 2 security group tags relates to network layer management rather than the specific whitelisting of cloud service IP addresses.
