Which best describes the purpose of a PAC file in Zscaler architecture?

• A. To store user passwords securely
• B. To route user traffic based on access policies
• C. To encrypt data sent over the network
• D. To monitor bandwidth usage

Answer: (B)

The purpose of a PAC (Proxy Auto-Configuration) file in Zscaler architecture is accurately captured by stating that it routes user traffic based on access policies. A PAC file is essentially a script that defines how web browsers and other user agents can automatically choose the appropriate proxy server for fetching resources. This functionality is crucial for directing traffic according to the specific needs and policies defined by the organization, allowing for dynamic and policy-driven routing. When a user’s device requests a resource, the PAC file helps determine which requests should go through Zscaler and which can go directly to their destination based on rules encoded within the file. This capability is integral for implementing security policies and ensuring efficient traffic management across the network. The other options do not align with the primary function of a PAC file. For example, storing user passwords securely does not relate to the PAC file’s role in traffic management. Similarly, while encrypting data and monitoring bandwidth usage are important aspects of network security and management, they do not fall under the specific operational function of a PAC file in routing traffic.
