NSE 8 – Network Security Expert (812) — Question 78

You are responsible for recommending an adapter type for NICs on a FortiGate VM that will run on an ESXi Hypervisor.
Your recommendation must consider performance as the main concern, cost is not a factor.
Which adapter type for the NICs will you recommend?

Answer options

• A. Native ESXi Networking with E1000
• B. Virtual Function (VF) PCI Passthrough
• C. Native ESXi Networking with VMXNET3
• D. Physical Function (PF) PCI Passthrough

Correct answer: D

Explanation

The Physical Function (PF) PCI Passthrough option provides the best performance as it allows direct access to the hardware, minimizing overhead. While VMXNET3 and E1000 are virtualized options, they cannot match the performance of PF PCI Passthrough. Virtual Function (VF) PCI Passthrough can offer good performance but is not as optimal as using PF.
