Which solution will meet these requirements?

Question210: A company has an on-premises application that collects data and stores it to an on-premises NFS server. The company recently set up a 10 Gbps AWS Direct Connect connection. The company is running out of storage capacity on premises. The company needs to migrate the application data from on premises to the AWS Cloud while maintaining low-latency access to the data from the on-premises application.
What should a solutions architect do to meet these requirements?

Question211: A company runs an application on a group of Amazon Linux EC2 instances The application writes log files using standard API calls For compliance reasons, all log files must be retained indefinitely and will be analyzed by a reporting tool that must access all files concurrently Which storage service should a solutions architect use to provide the MOST cost-effective solution?

Question212: An application tunning on AWS Lambda requires an API key to access a third-party service. The key must be stored securely with audited access to the Lambda function only.
What is the MOST secure way to store the key?

Question213: A company wants a storage option that enables its data science team to analyze its data on premises and in the AWS Cloud The team needs to be able to run statistical analyses by using the data on premises and by using a fleet of Amazon EC2 instances across multiple Availability Zones.
What should a solutions architect do to meet these requirements?

Question214: A solution architect must migrate a Windows internet information Services (IIS) web application to AWS. The application currently relies on a file share hosted in the user's on-premises network-attached storage (NAS).
The solution architected has proposed migrating the IIS web servers
Which replacement to the on-promises filo share is MOST resilient and durable?

Question215: A company is developing a real-time multiplier game that uses UDP for communications between client and servers in an Auto Scaling group Spikes in demand are anticipated during the day, so the game server platform must adapt accordingly. Developers want to store gamer scores and other non-relational data in a database solution that will scale without intervention.
Which solution should a solution architect recommend?

Question216: 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?

Question217: A company is building a payment application that must be highly available even during regional service disruptions A solutions architect must design a data storage solution that can be easily replicated and used in other AWS Regions. The application also requires low-latency atomicity, consistency, isolation, and durability (ACID) transactions that need to be immediately available to generate reports The development team also needs to use SQL.
Which data storage solution meets these requirements'?

Question218: A company has a two-tier application architecture that runs in public and private subnets Amazon EC2 instances running the web application are in the public subnet and a database runs on the private subnet The web application instances and the database are running in a single Availability Zone (AZ).
