Actual exam question for CompTIA's CV0-003 exam
Question #: 80
Topic #: 4
[All CV0-003 Questions]

An organization located in Asia connects to a cloud infrastructure hosted in North America and Europe. Sporadic slowness has been observed when using the PaaS and laaS components. A diagnostic using the following commands was run, and the following results were collected:

Which of the following is the most likely reason for the latency?

Show Suggested Answer Hide Answer
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).

Ah, the joys of cloud infrastructure. Bet they forgot to pay their cloud bill on time. That'll do it!

Switch failure at the organization? Come on, that's just too obvious. I'm going with the network security group option.

I agree, the network security group misconfiguration seems like a more likely reason for the latency.

Service degradation on the ISP, really? That's the easy way out. I bet it's a misconfiguration issue.

I'm not sure, but a DDoS attack seems a bit far-fetched in this scenario. It's probably more of a network configuration problem.

We should definitely look into the network security groups to see if there are any misconfigurations causing the slowness.

Hmm, I'm going to have to go with option C. Misconfigured network security groups can definitely cause latency issues when accessing cloud resources.
