Nutanix Certified Associate Practice Exam

When deploying applications on Nutanix Volumes, what factor could lead to degraded performance?

1. Using shared storage for multiple applications simultaneously.

2. Routing iSCSI traffic through non-optimal paths.

3. Connecting too many iSCSI initiators to a single volume group.

4. Utilizing faulty network interfaces on the VM.

The correct answer is: Routing iSCSI traffic through non-optimal paths.

Routing iSCSI traffic through non-optimal paths can significantly impact performance due to increased latency and reduced throughput. iSCSI (Internet Small Computer Systems Interface) relies on TCP/IP networks for transporting data between initiators and targets. If the network paths are not optimized, this can lead to increased delays in data transfer and can bottleneck network traffic. When iSCSI traffic takes inefficient routes, critical data packets may experience longer travel times or potential retransmissions due to timeouts, which can compound performance issues. Ensuring that iSCSI traffic routes through efficient, low-latency paths helps maintain higher throughput and reduced latency, resulting in better overall performance for applications relying on Nutanix Volumes. Other factors like shared storage, too many initiators to a volume group, or faulty network interfaces may impact performance as well, but routing traffic ineffectively poses a direct and systemic threat to overall application responsiveness and efficiency.
