A company wants to implement a work environment that will have low operational overhead and highly accessible enterprise resource planning, email, and data resources. Which of the following cloud service models should the company implement?
Answer(s): D
SaaS is the best choice for a company looking for low operational overhead and high accessibility for enterprise applications like ERP, email, and data resources. With SaaS, the cloud provider manages infrastructure, software maintenance, updates, and security, allowing the company to focus on usage rather than management. Examples include Microsoft 365 (email), SAP Cloud ERP, and Google Workspace.
Which of the following industry standards mentions that credit card data must not be exchanged or stored in cleartext?
PCI-DSS (Payment Card Industry Data Security Standard) explicitly mandates that credit card data must be encrypted both in transit and at rest and must not be stored in cleartext. It is designed to protect cardholder data and prevent unauthorized access, ensuring that businesses handling payment information comply with strict security requirements.
A company receives files daily from a bank. The company requires that the files must be copied from the cloud storage resource to another cloud storage resource for further processing. Which of the following methods requires the least amount of effort to achieve the task?
Answer(s): C
An event-driven architecture is the most efficient method for automatically copying files between cloud storage resources. By setting up an event trigger (e.g., a file upload to the cloud storage), the system can automatically respond to the event and initiate the process of copying the file to another storage resource without manual intervention. This minimizes effort and provides real-time processing.
An on-premises data center is located in an earthquake-prone location. The workload consists of real-time, online transaction processing. Which of the following data protection strategies should be used to back up on-premises data to the cloud while also being cost-effective?
Answer(s): A
Remote replication for failover is a highly effective strategy for backing up on-premises data to the cloud, especially in an earthquake-prone area. This approach involves replicating the data to a geographically separate cloud infrastructure, ensuring that the data is protected against natural disasters while enabling failover in case of an on-premises data center failure. It offers cost-effective disaster recovery and ensures high availability with minimal manual intervention.
A cloud engineer is deploying a cloud solution that will be used on premises with need-to-know access. Which of the following cloud deployment models best meets this requirement?
A private cloud deployment model is the most appropriate when the solution needs to be used on-premises with need-to-know access. It allows for a dedicated infrastructure that is managed either internally or by a third-party provider, and provides full control over security, access controls, and data management. In this case, the private cloud model allows for strict access controls to ensure that only authorized personnel can access the resources.
