How do Zscaler's cloud-native services benefit scalability?

The correct choice highlights a fundamental advantage of Zscaler's cloud-native services, which is their ability to allow immediate resource allocation based on demand. In a cloud-native environment, resources can be dynamically scaled up or down in response to varying workloads without the need for significant physical infrastructure changes. This flexibility ensures that users have access to the resources they need at any given moment, enhancing performance and operational efficiency.

By leveraging cloud-native architecture, organizations can adapt to increasing or decreasing user needs in real-time, which is especially crucial in scenarios such as fluctuating web traffic or increasing numbers of remote users. Consequently, this approach optimizes the use of resources while minimizing costs.

In contrast, increasing hardware requirements would inhibit scalability, as it involves purchasing and deploying additional physical resources, which takes time and is less adaptable. Restricting access to internal networks is more about security measures rather than scalability. While it aids in controlling and managing network traffic, it does not inherently relate to the dynamic scaling of resources. Improving latency issues might be a consideration for performance optimization, but it is not directly tied to the scalability benefits provided by cloud-native services.
