A company wants to build its new platform using a public cloud. The workload requirements include the following:· Implementation of custom CIS compliance· Patch for vulnerabilities within 24 hours· Warrant at least 1,800 IOPS per volumeWhich of the following meets the requirements?
Answer(s): B
Infrastructure as a Service (IaaS) provides the most flexibility among cloud service models, allowing for the implementation of custom security and compliance standards, such as CIS compliance. IaaS environments offer control over the infrastructure, enabling patch management within specific time frames. Additionally, IaaS providers typically offer configurable storage options, including the ability to specify IOPS (Input/Output Operations Per Second) per volume to meet performance requirements.
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?
A Virtual Private Network (VPN) is the most cost-effective solution for extending on-premises services to a public cloud while ensuring secure remote connectivity. VPNs can be configured to avoid IP address conflicts and overlap by using IP address translation and tunneling techniques, making them suitable for connecting disparate environments without significant changes to the existing network infrastructure.
An administrator is creating a cron job that shuts down the virtual machines at night to save on costs. Which of the following is the best way to achieve this task?A)B)C)D)
Answer(s): C
Option C is the correct script for shutting down virtual machines that are currently running. It iterates through a list of VMs, checks if the status of each VM is 'running', and if so, proceeds to shut down the VM. The script then prints a message stating that the VM has been stopped. This approach ensures that only VMs that are actively running are targeted for shutdown, optimizing resource utilization and cost savings.
A cloud engineer is developing an operating expense report that will be used to purchase various cloud billing models for virtual machine instances. The cloud billing model must meet the following requirements:· The instance cannot be ephemeral.· The minimum life cycle of the instance is expected to be five years. · The software license is charged per physical CPU count. Which of the following models would best meet these requirements?
Answer(s): D
Reserved resources, or Reserved Instances, are ideal for workloads with predictable usage and a long-term commitment, such as a minimum lifecycle of five years. This model allows for significant cost savings compared to on-demand pricing, and the instance is not ephemeral, meaning it persists and is dedicated to the user for the duration of the reservation. The licensing charged per physical CPU count aligns with dedicated host or reserved instance models, but the long-term commitment points more towards reserved resources.
