Question
Due to application requirements, an administrator needs to modify an AHV VM in order to support a large number of distinct, concurrent connections. The VM has the following configuration:
- VCPUs: 4
- RAM: 20 GB
- Operating System: Microsoft Windows Server 2022
Which modification can the administrator make to improve network performance for network I/O- intensive applications running on this VM?
Options
- AEnabling RSS Virtio-Net Multi-Queue
- BAdding more VCPUs
- CAdding more RAM
- DEnabling AHV Turbo Technology

Explanation
RSS (Receive Side Scaling) Virtio-Net Multi-Queue allows network packet processing to be distributed across multiple CPU cores simultaneously, which is essential for applications handling a large number of distinct, concurrent network connections. Without multi-queue, all network I/O is funneled through a single CPU core, creating a bottleneck. Enabling RSS Virtio-Net Multi-Queue directly addresses the network I/O concurrency bottleneck. Adding more vCPUs (B) alone does not help unless the network driver can actually use them for packet processing. Adding RAM (C) improves memory-bound workloads, not network throughput. AHV Turbo (D) improves CPU scheduling efficiency but does not specifically address concurrent network connection scalability.
