A systems administrator is troubleshooting a performance issue with a virtual database server. The administrator has identified the issue as being disk related and believes the cause is a lack of IOPS on the existing spinning disk storage. Which of the following should the administrator do NEXT to resolve this issue?
Answer(s): B
B. Move the virtual machine to flash storage and test again.If a performance issue has been identified as disk related and the cause is determined to be a lack of IOPS on the existing spinning disk storage, the next step to resolve the issue should be to move the virtual machine to flash storage and test again. Flash storage is known to have a much higher IOPS capacity than spinning disk storage, which should help to resolve the performance issue. Upgrading the virtual database server or checking if other machines on the same storage are having issues may not necessarily resolve the disk-related performance issue. Documenting the findings and placing them in a shared knowledge base is important, but it should not be the next step in resolving the issue.
In an existing IaaS instance, it is required to deploy a single application that has different versions. Which of the following should be recommended to meet this requirement?
Answer(s): A
Containers are a lightweight virtualization technology that allows you to run multiple applications on the same host machine. This is because containers share the host machine's operating system kernel, which reduces the amount of resources that each container needs.In this case, the requirement is to deploy a single application that has different versions. This can be easily achieved by deploying each version of the application in a separate container. This will allow the different versions of the application to coexist on the same host machine without interfering with each other.
An organization is using multiple SaaS-based business applications, and the systems administrator is unable to monitor and control the use of these subscriptions.The administrator needs to implement a solution that will help the organization apply security policies and monitor each individual SaaS subscription. Which of the following should be deployed to achieve these requirements?
To monitor and control the use of SaaS subscriptions, the best solution to deploy is a Cloud Access Security Broker (CASB). A CASB provides visibility and control over data that resides in cloud applications, including SaaS-based applications. It can help an organization apply security policies and monitor each individual SaaS subscription by providing features such as identity and access management, data loss prevention, threat protection, and compliance reporting. Therefore, option B is the correct answer.
A cloud administrator needs to reduce the cost of cloud services by using the company's off-peak period. Which of the following would be the BEST way to achieve this with minimal effort?
Answer(s): C
An auto-shutdown group is a group of cloud resources that are automatically shut down during off-peak periods. This can help to reduce the cost of cloud services by only paying for the resources that are actively being used.
