What feature significantly enhances the capability of VM-Series firewall deployments in PAN-OS 10.2?

1. Dependency on older VM models

2. Licensing based on memory requirements

3. Support for multiple physical instances

4. Flexibility in vCPU resource allocation

The correct answer is: Flexibility in vCPU resource allocation

The selected answer highlights a crucial enhancement in the VM-Series firewall deployments with PAN-OS 10.2, specifically regarding the flexibility in vCPU resource allocation. This flexibility allows organizations to optimize the performance of their VM-Series firewalls based on specific workload requirements, enabling a more tailored response to varying traffic conditions and demands. By being able to allocate vCPU resources dynamically, organizations can better balance their security needs with resource availability, ensuring efficient performance without over-provisioning or under-utilizing resources. This adaptability is vital in virtualized environments where workload characteristics can change frequently and unpredictably. Consequently, organizations can experience improved throughput and latency, enhancing overall network security management. The other options do not provide the same level of utility or enhancement as the flexibility in vCPU resource allocation. For instance, dependency on older VM models would limit the capability and benefits that newer technology offers, while licensing based on memory requirements might introduce constraints rather than enhancing performance. Support for multiple physical instances, while useful, does not address the resource optimization that comes with flexible vCPU allocation, which is more directly impactful on firewall performance in dynamic environments.
