CompTIA Cloud Essentials+: CLO-002

Correct Answer: D

Explanation: Availability is the degree to which a system or service is accessible and functional when required. Availability can be measured by metrics such as uptime, downtime, and service level agreements (SLAs). Availability can be improved by implementing replication, redundancy, and disaster recovery strategies in the cloud. Replication is the process of creating and maintaining multiple copies of data or resources across different locations or regions. Redundancy is the provision of extra or backup components or systems to prevent or mitigate failures. Disaster recovery is the ability to restore normal operations after a disruptive event, such as a natural disaster, a cyberattack, or a human error. By implementing these strategies, cloud users can ensure that their data and services are always accessible and resilient to failures or disasters.

Correct Answer: BE

Explanation: Elasticity and pay-as-you-go are two main advantages of using ML/AI for data analytics in the cloud as opposed to on premises. Elasticity refers to the ability of cloud computing to dynamically adjust the amount of resources allocated to a workload according to the changing demand7. This allows ML/AI applications to access a large pool of compute resources when needed, such as GPUs or TPUs, without having to purchase or maintain them on premises8. Pay-as-you-go is a pricing model in which customers pay only for the resources they consume, such as compute, storage, network, or software services9. This allows ML/AI applications to save money by avoiding upfront costs or overprovisioning of resources on premises10.

Correct Answer: B

Explanation: After documenting the business use-case scenarios, the architect's next step should be to conduct a feasibility study. A feasibility study is an analysis of the viability and suitability of a proposed solution or project, such as migrating to the cloud. A feasibility study evaluates the technical, operational, financial, legal, and ethical aspects of the solution, as well as the risks and benefits involved. A feasibility study helps the architect to determine if the solution is feasible, desirable, and achievable, and to identify any potential issues or challenges that may arise1. A feasibility study is one of the key components of a cloud assessment, which is a process of evaluating the readiness and suitability of an organization for cloud adoption1. A proof of concept (PoC) is a demonstration or prototype of a solution that shows how it works and what it can achieve. A PoC is usually done after a feasibility study, when the solution has been proven to be feasible and the requirements have been defined1. A gap analysis is a comparison of the current state and the desired state of a process, system, or organization. A gap analysis identifies the gaps or differences between the two states, and the actions or resources needed to close them. A gap analysis is usually done after a feasibility study and a PoC, when the solution has been validated and the goals have been established1. Gathering cloud requirements is the process of collecting and analyzing the needs and expectations of the stakeholders for the cloud solution. Gathering cloud requirements is usually done after a feasibility study and before a PoC, when the solution has been confirmed to be feasible and the scope has been defined1.
