Which solution meets these requirements?

Question212: A company hosts its static website content from an Amazon S3 bucket in the us-east-1 Region.
Content is made available through an Amazon CloudFront origin pointing to that bucket. Cross- Region replication is set to create a second copy of the bucket in the ap-southeast-1 Region.
Management wants a solution that provides greater availability for the website.
Which combination of actions should a solutions architect take to increase availability? (Choose two.)

Question213: A company is deploying a public-facing global application on AWS using Amazon CloudFront.
The application communicates with an external system. A solutions architect needs to ensure the data is secured during end-to-end transit and at rest.
Which combination of steps will satisfy these requirements? (Select TWO)

Question214: A company receives structured and semi-structured data from various sources once every day.
A solutions architect needs to design a solution that leverages big data processing frameworks.
The data should be accessible using SQL queries and business intelligence tools.
What should the solutions architect recommend to build the MOST high-performing solution?

Question215: A company wants to deploy an additional Amazon Aurora MySQL DB cluster for development purposes.
The cluster will be used several times a week for a few minutes upon to debug production query issues.
The company wants to keep overhead low for this resource.
Which solution meets the company's requirements MOST cost-effectively?

Question216: A company runs an application on three very large Amazon EC2 instances.
In a single Availability Zone in the us-east-1 Region Multiple 16 TB Amazon Elastic Block Store (Amazon EBS) volumes are attached to each EC2 instance.
The operations team uses an AWS Lambda script triggered by a schedule-based Amazon EventBridge (Amazon CloudWatch Events) rule to stop the instances on evenings and weekends, and start the instances on weekday mornings.
Before deploying the solution, the company used the public AWS pricing documentation to estimate the overall costs of running this data warehouse solution 5 days a week for 10 hours a day.
When looking at monthly Cost Explorer charges for this new account, the overall charges are higher than the estimate.
What is the MOST likely cost factor that the company overlooked?

Question217: A company is running a batch application on Amazon EC2 instances.
The application consists of a backend with multiple Amazon RDS databases.
The application is causing a high number of reads on the databases.
A solutions architect must reduce the number of database reads while ensuring high availability.
What should the solutions architect do to meet this requirement?

Question218: A solutions architect is designing an application for a two-step order process.
The first step is synchronous and must return to the user with little latency.
The second step takes longer, so it will be implemented in a separate component Orders must be processed exactly once and in the order in which they are received.
How should the solutions architect integrate these components?

Question219: A company is running an ecommerce application on Amazon EC2.
The application consists of a stateless web tier that requires a minimum of 10 instances, and a peak of 250 instances to support the application's usage.
The application requires 50 instances 80% of the time.
Which solution should be used to minimize costs?

Question220: A solutions architect is designing storage for a high performance computing (HPC) environment based on Amazon Linux.
The workload stores and processes a large amount of engineering drawings that require shared storage and heavy computing.
Which storage option would be the optimal solution?

Question221: A company is performing an AWS Well-Architected Framework review of an existing workload deployed on AWS.
The review identified a public-facing website running on the same Amazon EC2 instance as a Microsoft Active Directory domain controller that was install recently to support other AWS services.
