A cloud administrator recently noticed that a number of files stored at a SaaS provider’s file-sharing service were deleted. As part of the root cause analysis, the administrator noticed the parent folder permissions were modified last week. The administrator then used a test user account and determined the permissions on the files allowed everyone to have write access.
Which of the following is the best step for the administrator to take NEXT?
Correct Answer:
D
Permissions are rules or settings that determine what actions users can perform on files or resources in a system or service. Permissions can help control and restrict access to files or resources based on various criteria, such as user identity, role, group, or ownership. Defining and configuring the proper permissions for the file-sharing service is the best step for the administrator to take next after discovering that sales group members can access the financial application due to being part of the finance group and having write access to all files in the file-sharing service. Defining and configuring the proper permissions can prevent unauthorized or accidental access or modification of files or resources by limiting or granting access based on specific criteria.

A cloud engineer needs to perform a database migration. The database has a restricted SLA and cannot be offline for more than ten minutes per month. The database stores 800GB of data, and the network bandwidth to the CSP is 100MBps Which of the following is the best option to perform the migration?
Correct Answer:
B
The best option to perform the database migration is to create a replica database, synchronize the data, and switch to the new instance. This option can help meet the restricted SLA and avoid offline time for the database. Creating a replica database can help copy the data from the source to the destination without interrupting the database operations. Synchronizing the data can help ensure that the replica database is updated with any changes that occur in the source database during the migration process. Switching to the new instance can help complete the migration and activate the new database in the cloud. This option can also help avoid the network bandwidth limitation and the large size of the data.

An administrator recently provisioned a file server in the cloud. Based on financial considerations, the administrator has a limited amount of disk space. Which of the following will help control the amount of space that is being used?
Correct Answer:
C
User quotas are what will help control the amount of space that is being used by a file server in the cloud that has a limited amount of disk space due to financial considerations. User quotas are the limits or restrictions that are imposed on the amount of space that each user can use or consume on a file server or storage device. User quotas can help to control the amount of space that is being used by:
✑ Preventing or reducing wastage or overuse of space by users who may store unnecessary or redundant files or data on the file server or storage device.
✑ Ensuring fair and equal distribution or allocation of space among users who may have different needs or demands for space on the file server or storage device.
✑ Monitoring and managing the usage or consumption of space by users who may need to be notified or alerted when they reach or exceed their quota on the file server or storage device.

A systems administrator wants the VMs on the hypervisor to share CPU resources on the same core when feasible.
Which of the following will BEST achieve this goal?
Correct Answer:
E
Simultaneous multithreading (SMT) is a type of CPU technology that allows multiple threads to run concurrently on a single CPU core. Enabling SMT can help achieve
the goal of having the VMs on the hypervisor share CPU resources on the same core when feasible, as it can increase the CPU utilization and efficiency by executing more instructions per cycle and reducing idle time or wasted cycles. Enabling SMT can also improve performance and throughput, as it can speed up processing and handle increased workload or demand.

A business is looking at extending the platform for an internally developed application using microservices from various cloud vendors. The cloud architect is responsible for reviewing the proposed solution design, which covers critical requirements for the business to fulfill its requirements. Which of the following is the most likely requirement the cloud architect needs to fulfill?
Correct Answer:
D
Integration is the process of connecting and coordinating different components or systems to work together as a whole. In this scenario, the business is looking at extending the platform for an internally developed application using microservices from various cloud vendors. This means that the cloud architect needs to ensure that the microservices can communicate and interact with each other across different cloud platforms, as well as with the existing application. Integration is a critical requirement for the business to fulfill its requirements, as it affects the functionality, performance, and reliability of the application. Software, budgetary, and security are also important requirements, but they are not the most likely ones that the cloud architect needs to fulfill in this scenario. Software refers to the programs and applications that run on the cloud platforms. Budgetary refers to the costs and expenses associated with the cloud services and solutions. Security refers to the protection of the data and resources in the cloud environment from unauthorized access or attacks.
