A cloud engineer is extending on-premises services to a public cloud. The following design requirements must be considered in the overall solution:-The ability to remotely connect systems from both environments-No IP address conflicts or overlap-Cost-effectivenessWhich of the following cloud network concepts best meets these requirements?
Answer(s): B
A VPN (Virtual Private Network) is the most cost-effective solution for securely extending on-premises services to a public cloud while meeting the specified requirements:-Remote connectivity: A VPN allows secure communication between the on-premises network and the cloud over the internet.-No IP conflicts: VPN connections can be configured with route-based or policy-based options to ensure proper network segmentation without IP address overlap.-Cost-effectiveness: Unlike dedicated connections (such as Direct Connect or ExpressRoute), VPNs do not require physical infrastructure and can be implemented at a lower cost using existing internet connections.-
A cloud engineer wants to replace the current on-premises, unstructured data storage with a solution in the cloud. The new solution needs to be cost-effective and highly scalable. Which of the following types of storage would be best to use?
Answer(s): C
Object storage is the best solution for replacing on-premises unstructured data storage in the cloud because it is highly scalable, cost-effective, and optimized for storing large amounts of unstructured data (e.g., images, videos, logs, backups). Cloud object storage solutions, such as AWS S3, Azure Blob Storage, and Google Cloud Storage, provide high availability, redundancy, and flexible access control without requiring complex infrastructure management.
A systems administrator is configuring backups on a VM and needs the process to run as quickly as possible, reducing the bandwidth on the network during all times from Monday through Saturday. In the event of data corruption, the management team expects the mean time to recovery to be as low as possible. Which of the following backup methods can the administrator use to accomplish these goals?
This hybrid backup approach balances speed, bandwidth efficiency, and recovery time:-Full backup on Sunday ensures a complete dataset is stored at least once a week.-Incremental backups Monday–Saturday only save changes since the last backup, minimizing network bandwidth usage and making daily backups run faster.-Fast recovery (low Mean Time to Recovery - MTTR) is achieved by restoring the latest full backup followed by applying only the necessary incremental backups.-
A company has ten cloud engineers working on different manual cloud deployments. In the past, engineers have had difficulty keeping deployments consistent. Which of the following is the best method to address this issue?
Configuration as Code (CaC) ensures that all cloud deployments are consistent, repeatable, and automated by defining infrastructure configurations in code (e.g., Terraform, AWS CloudFormation, Ansible). This eliminates inconsistencies caused by manual deployments, reduces human errors, and enables version control, making it easier to track changes and collaborate effectively among multiple engineers.
A high-usage cloud resource needs to be monitored in real time on specific events to guarantee its availability. Which of the following actions should be used to meet this requirement?
A real-time monitoring dashboard provides continuous visibility into the status of a high-usage cloud resource, enabling proactive response to potential issues. Dashboards aggregate real-time logs, performance metrics, and alerts to detect failures or performance degradation immediately. This approach helps guarantee availability by allowing administrators to act on specific events as they happen, rather than relying on periodic checks or post-incident analysis.
