An administrator needs to modify an AHV VM to support a large number of concurrent network connections. The VM has: 4 vCPUs 20 GB RAM OS: Microsoft Windows Server 2022 Which modification can improve…

Question

Options

• AAdd more vCPUs.
• BEnable AHV Turbo Technology.
• CEnable RSS VirtIO-Net Multi-Queue.
• DAdd more RAM.

• A
  7% (3)
• B
  2% (1)
• C
  77% (34)
• D
  14% (6)

Explanation

Enabling RSS (Receive Side Scaling) with VirtIO-Net Multi-Queue distributes incoming and outgoing network packet processing across multiple CPU queues simultaneously. Without multi-queue, all network interrupts are handled by a single CPU core, creating a bottleneck under high connection counts. With RSS VirtIO-Net Multi-Queue enabled, the virtual NIC can spread the network I/O load across multiple vCPUs in parallel, dramatically improving throughput, reducing latency, and increasing the number of concurrent connections the VM can handle.

Why the other options are wrong:

• A (Add more vCPUs): Adding vCPUs increases compute capacity but does not address the network I/O bottleneck unless multi-queue is also enabled to utilize those CPUs for network processing.
• B (Enable AHV Turbo Technology): AHV Turbo Technology improves storage I/O performance by optimizing the I/O path for disk operations; it does not affect network performance.
• D (Add more RAM): Additional RAM helps with memory-intensive or high-caching workloads; it does not improve network connection handling or throughput.
