Five thousand employees always access the company’s public cloud-hosted web application on a daily basis during the same time frame. Some users have been reporting performance issues while attempting to connect to the web application. Which of the following is the best configuration approach to resolve this issue?
Answer(s): B
Scaling horizontally means adding more instances of the application or servers to handle increased traffic, rather than increasing the resources (CPU, memory) of a single server (which would be vertical scaling). Since the performance issues occur during a specific, predictable time frame every day, scaling horizontally based on a schedule would ensure that additional resources are available when needed, improving performance without waiting for a load threshold to be reached.
A cloud engineer is reviewing a disaster recovery plan that includes the following requirements:-System state, files, and configurations must be backed up on a weekly basis.-The system state, file, and configuration backups must be tested annually.Which of the following backup methods should the engineer implement for the first week the plan is executed?
Answer(s): D
A full backup is the best method to implement for the first week because it creates a complete backup of all system state, files, and configurations. This provides a comprehensive baseline that can be used for future differential or incremental backups. A full backup is essential as the initial backup in any backup strategy, as it ensures that all data is captured and can be used as a reference for subsequent, smaller backups.
Which of the following is a direct effect of cloud migration on an enterprise?
A direct effect of cloud migration is that fewer on-premises resources are required, leading to a reduction in utility costs such as electricity and cooling for data centers. As workloads move to the cloud, physical infrastructure on-premises is reduced or no longer needed, directly impacting and lowering these operational costs.
A company wants to create a few additional VDIs so support vendors and contractors have a secure method to access the company's cloud environment. When a cloud administrator attempts to create the additional instances in the new locations, the operation is successful in some locations but fails in others. Which of the following is the most likely reason for this failure?
The most likely reason for the failure in creating virtual desktop instances (VDIs) in some locations but not others is regional service availability. Different cloud regions may offer varying services and resources. If a specific region does not support the VDI service or has limited availability, the operation would fail in those regions while succeeding in others. This issue is common in cloud environments, where certain services are not universally available in all regions.
An administrator used a script that worked in the past to create and tag five virtual machines. All of the virtual machines have been created; however, the administrator sees the following results:{tags: []}Which of the following is the most likely reason for this result?
Answer(s): C
If a script that previously worked to create and tag virtual machines now results in the {tags: []} output, it likely means that the command or method used to apply tags has been deprecated or changed. When commands or APIs are updated, older methods may no longer function as expected, especially for tagging, which can result in the tags not being applied. This is a common issue when scripts are used over a long period, as cloud providers frequently update and deprecate certain commands.
