NEW QUESTION 11

A company wants its Amazon EC2 instances to share the same geographic area but use redundant underlying power sources.
Which solution will meet these requirements?

• A. Use EC2 instances across multiple Availability Zones in the same AWS Region.
• B. Use Amazon CloudFront as the database for the EC2 instances.
• C. Use EC2 instances in the same edge location and the same Availability Zone.
• D. Use EC2 instances in AWS OpsWorks stacks in different AWS Regions.

Answer: A

Explanation:
Using EC2 instances across multiple Availability Zones in the same AWS Region is a solution that meets the requirements of sharing the same geographic area but using redundant underlying power sources. Availability Zones are isolated locations within an AWS Region that have independent power, cooling, and physical security. They are connected through low-latency, high-throughput, and highly redundant networking. By launching EC2 instances in different Availability Zones, users can increase the fault tolerance and availability of their applications. Amazon CloudFront is a content delivery network (CDN) service that speeds up the delivery of web content and media to end users by caching it at the edge locations closer to them. It is not a database service and cannot be used to store operational data for EC2 instances. Edge locations are sites that are part of the Amazon CloudFront network and are located in many cities around the world. They are not the same as Availability Zones and do not provide redundancy for EC2 instances. AWS OpsWorks is a configuration management service that allows users to automate the deployment and management of applications using Chef or Puppet. It can be used to create stacks that span multiple AWS Regions, but this would not meet the requirement of sharing the same geographic area.

Which AWS Support plan provides customers with access to an AWS technical account manager (TAM)?

• A. AWS Basic Support
• B. AWS Developer Support
• C. AWS Business Support
• D. AWS Enterprise Support

Answer: D

Explanation:
The correct answer is D because AWS Enterprise Support is the support plan that provides customers with access to an AWS technical account manager (TAM). AWS Enterprise Support is the highest level of support plan offered by AWS, and it provides customers with the most comprehensive and personalized support experience. An AWS TAM is a dedicated technical resource who works closely with customers to understand their business and technical needs, provide proactive guidance, and coordinate support across AWS teams. The other options are incorrect because they are not support plans that provide customers with access to an AWS TAM. AWS Basic Support is the default and free support plan that provides customers with access to online documentation, forums, and account information. AWS Developer Support is the lowest level of paid support plan that provides customers with access to technical support during business hours, general guidance, and best practice recommendations. AWS Business Support is the intermediate level of paid support plan that provides customers with access to technical support 24/7, system health checks, architectural guidance, and case management.

NEW QUESTION 16

A company wants to launch multiple workloads on AWS. Each workload is related to a different business unit. The company wants to separate and track costs for each business unit.
Which solution will meet these requirements with the LEAST operational overhead?

• A. Use AWS Organizations and create one account for each business unit.
• B. Use a spreadsheet to control the owners and cost of each resource.
• C. Use an Amazon DynamoDB table to record costs for each business unit.
• D. Use the AWS Billing console to assign owners to resources and track costs.

Answer: A

Explanation:
AWS Organizations is a service that helps you centrally manage and govern your AWS environment. You can use AWS Organizations to create multiple accounts for different business units, and group them into organizational units (OUs) that reflect your organizational structure1. By doing so, you can separate and track costs for each business unit using the account ID as a cost allocation tag2. You can also use AWS Organizations to apply policies and controls to your accounts, such as service control policies (SCPs) and tag policies1.
The other options are not suitable for meeting the requirements with the least operational overhead. Using a spreadsheet or a DynamoDB table to control and record costs for each business unit would require manual data entry and maintenance, which is prone to errors and inconsistencies. Using the AWS Billing console to assign owners to resources and track costs would also require manual tagging of each resource, which is time-consuming and inefficient.
