Question 7 - N10-008 discussion

A client recently added 100 users who are using VMs. All users have since reported slow or unresponsive desktops. Reports show minimal network congestion, zero packet loss, and acceptable packet delay. Which of the following metrics will MOST accurately show the underlying performance issues? (Choose two.)

CPU usage

Memory

Temperature

Bandwidth

Latency

Jitter

Suggested answer: A, B

Explanation:

The question asks about the metrics that will most accurately show the underlying performanceissues of slow or unresponsive desktops for users who are using VMs (virtual machines).VMs are software-based simulations of physical computers that run on a host system. Theyshare the resources of the host system, such as CPU, memory, disk space, etc.If the host system does not have enough resources to support the number of VMs running on it,the performance of the VMs will suffer. This is especially true if the VMs are running resource-intensive applications or tasks.Therefore, the metrics that will most accurately show the underlying performance issuesareCPU usageandmemory. These metrics indicate how much of the host system's resources arebeing consumed by the VMs and how much is available for other processes.The other metrics are not relevant to the question, as they are related to the networkperformance, not the host system performance. They are:Temperature: the measure of how hot the host system or its components are. Hightemperature can cause overheating and damage to the hardware, but it is not directly relatedto the performance of the VMs.Bandwidth: the measure of how much data can be transferred over a network connection in agiven time. Low bandwidth can cause network congestion and slow data transfer, but it is notdirectly related to the performance of the VMs.Latency: the measure of how long it takes for a data packet to travel from one point to anotheron a network. High latency can cause delays and poor quality of service, but it is not directlyrelated to the performance of the VMs.Jitter: the measure of how much the latency varies over time on a network. High jitter cancause inconsistent and unpredictable network performance, but it is not directly related to theperformance of the VMs.
