Tagging is what the administrator should implement first to assist with reporting the cost for each business unit for applications in a public cloud environment. Tagging is a technique that allows customers to assign metadata or labels to their cloud resources, such as applications, instances, volumes, etc., based on their attributes or criteria. Tagging can help customers to organize, manage, monitor, and report their cloud resources and costs by business unit, project, owner, environment, etc.

 To troubleshoot the performance of a scheduled job that takes two hours to run after onboarding 10,000 new users to a cloud-based system, the administrator should evaluate the IaaS compute configurations, the capacity trend analysis reports, and the storage IOPS. These factors can affect the performance of a database job in an IaaS instance on a cloud provider. The IaaS compute configurations include the CPU, memory, and network resources assigned to the instance. The capacity trend analysis reports show the historical and projected usage and demand of the resources. The storage IOPS (Input/Output Operations Per Second) measure the speed and performance of the disk storage. The administrator should check if these factors are sufficient, optimal, or need to be adjusted to improve the performance of the job.

Creating an auto-shutdown group is the best way to reduce the cost of cloud services by using the company’s off-peak period with minimal effort. An auto-shutdown group is a feature that allows customers to automatically turn off or shut down certain cloud resources or services during a specified time period or schedule. An auto-shutdown group can help to reduce the cost of cloud services by minimizing the consumption of resources or services during off-peak periods, when they are not needed or used. An auto-shutdown group can also help to reduce the effort of managing cloud resources or services by automating the shutdown process, without requiring any manual intervention or configuration.

Asking the user if the client device or access location has changed is what the help desk technician should do first to troubleshoot poor-quality remote VDI (Virtual Desktop Infrastructure) session. VDI is a technology that allows users to access virtual desktops hosted on remote servers over a network or internet connection. VDI can provide users with flexibility, mobility, and security, but it may also introduce quality issues depending on various factors, such as:

• The client device: This is the device that users use to access their virtual desktops, such as a laptop, tablet, smartphone, etc. The client device can affect VDI quality by determining how well it can support and display virtual desktop applications and services, as well as how fast it can process and send data over a network or internet connection.
• The access location: This is where users access their virtual desktops from, such as home, office, public place, etc. The access location can affect VDI quality by determining how stable and secure their network or internet connection is, as well as how much latency or interference they may experience.

Asking the user if these factors have changed can help to troubleshoot poor-quality remote VDI session by identifying any potential causes or sources of quality issues, as well as suggesting any possible solutions or alternatives.
