CV0-004 Question #17: Real Exam Question with Answer & Explanation

Question

A cloud engineer has provisioned a VM for a high-frequency trading application. After the VM is put into production, users report high latency in trades. The engineer checks the last six hours of VM metrics and sees the following: - CPU utilization is between 30% to 60%. - Networkln is between 50Kbps and 70Kbps. - NetworkOut is between 3.000Kpbs and 5.000Kbps. - DiskReadOps is at 30. - DiskWriteOps is at 70 - Memory utilization is between 50% and 70%. Which of the following steps should the engineer take next to solve the latency issue?

Options

• AMove to a network-optimized instance type as the network throughput is not enough.
• BModify the disk IOPS to a higher value as the disk IO is being bottlenecked at 100 IOPS.
• CIncrease the memory of the instance as the high-frequency trading application requires more
• DIncrease the instance size to allocate more vCPUs as the CPU utilization is very high.

Explanation

Since the NetworkOut is significantly higher than NetworkIn and considering the nature of a high- frequency trading application, the issue most likely lies with network throughput. Moving to a network-optimized instance type would provide higher network bandwidth, which can reduce latency in trades.
