[All CV0-003 Questions]

An administrator has been informed that some requests are taking a longer time to respond than other requests of the same type. The cloud consumer is using multiple network service providers and is performing link load balancing for bandwidth aggregation. Which of the following commands will help the administrator understand the possible latency issues?

Suggested Answer: C

SR-IOV stands for Single Root I/O Virtualization, which is a technology that allows a physical network adapter to be partitioned into multiple virtual functions (VFs) that can be directly assigned to virtual machines (VMs). This way, the network traffic bypasses the software layer of the hypervisor and the virtual switch, and goes directly from the VM to the physical adapter. This reduces the CPU overhead, the network latency, and the packet loss, and improves the network throughput and scalability. SR-IOV can achieve near-native performance for network-intensive applications, such as an integration application that communicates between different application and database servers. By enabling SR-IOV capability on the physical server and the virtual server, the P2V migration can maintain the same level of network throughput and latency as the original physical machine.Reference:High performance network virtualization with SR-IOV;Supercharge Your Network Throughput via Single Root I/O Virtualization (SR-IOV);Overview of Single Root I/O Virtualization (SR-IOV).

Traceroute definitely seems like the right choice here. It can help identify any bottlenecks or high-latency hops along the network path.

I'm not sure, but I think ping could also be useful to check the response time of each hop.

I agree with Kaitlyn. Traceroute can help identify the network hops causing latency.
