nswer: C.
Option A is incorrect.
Instead of heavily investing in Data Centers & Servers for hosting their applications, clients can consume resources from the AWS Cloud, e.g., Compute, Storage, and only pay for the resources they have consumed.
So Capital Expenditure (CAPEX) gets converted into Operational Expenditure (OPEX) while using a Cloud environment that results in Cost Efficiency for the client.
Option B is incorrect.
The AWS Cloud model helps eliminating to guess infrastructure capacity needs by offering a Scale on Demand model.
For example, during Christmas when there is a sudden increase in website traffic, additional resources (like EC2) can be created On-Demand (Scale- Up) to address the surge in traffic.
Similarly, when the festival period goes away, the additional resources that were created can be terminated (Scale - Down) so that the user does not need to pay for idle resources.
Option C is CORRECT.
AWS Cloud adopts a Shared Responsibility Model where Security & Compliance responsibility is shared between the Client & AWS.
This shared responsibility security model helps relieve the client of operational burden as AWS operates, manages & controls the components from the host Operating System and Virtualization layer down to the physical security of its facilities (Data Center's)
The client can effectively manage the Security of his applications & the infrastructure in which it resides.
AWS also helps customers to understand their robust controls in place to maintain security and compliance in the Cloud through their compliance certifications e.g., PCI DSS compliance.
Option D is incorrect.
AWS Cloud allows clients to focus on their Projects that differentiate their business rather than maintaining infrastructure.
AWS performs all the heavy lifting of maintaining facilities (Data Centers).
