1. Right Answer: B
Explanation: AWS TCO calculators allow you to estimate the cost savings when using AWS and provide a detailed set of reports that can be used in executive presentations. The calculators also give you the option to modify assumptions that best meet your business needs.https://aws.amazon.com/tco-calculator/

2. Right Answer: B
Explanation: The way that Reserved Instance discounts apply to accounts in an organization's consolidated billing family depends on whether Reserved Instance sharing is turned on or off for the account. By default, Reserved Instance sharing for all accounts in an organization is turned on. You can change this setting by Turning Off Reserved Instance Sharing for an account. The capacity reservation for a Reserved Instance applies only to the account the Reserved Instance was purchased on, regardless of whether Reserved Instance sharing is turned on or off.https://aws.amazon.com/premiumsupport/knowledge-center/ec2-ri-consolidated-billing/

3. Right Answer: B
Explanation: You can use the consolidated billing feature in AWS Organizations to consolidate billing and payment for multiple AWS accounts or multiple Amazon Internet Services Pvt. Ltd (AISPL) accounts. Every organization in AWS Organizations has a master (payer) account that pays the charges of all the member (linked) accounts.https://docs.aws.amazon.com/awsaccountbilling/latest/aboutv2/consolidated-billing.html

4. Right Answer: A
Explanation: Use AWS Local Zones to deploy workloads closer to your end-users for low-latency requirements.

5. Right Answer: C
Explanation: The cloud allows you to trade capital expenses (such as data centers and physical servers) for variable expenses, and only pay for IT as you consume it.
