Amazon (SAA-C03) Exam Questions And Answers page 18
A company is building applications in containers. The company wants to migrate its on-premises development and operations services from its on-premises data center to AWS. Management states that production systems must be cloud agnostic and use the same configuration and administrator tools across production systems. A solutions architect needs to design a managed solution that will align open-source software.
Which solution meets these requirements?
Which solution meets these requirements?
Launch the containers on Amazon Elastic Kubernetes Service (Amazon EKS) and EKS worker nodes.
Launch the containers on Amazon Elastic Containers service (Amazon ECS) with AWS Fargate instances.
Launch the containers on Amazon Elastic Container Service (Amazon ECS) with Amazon EC2 instance worker nodes.

A company is building a web application that serves a content management system. The content management system runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The EC2 instances run in an Auto Scaling group across multiple Availability Zones. Users are constantly adding and updating files, blogs, and other website assets in the content management system.
A solutions architect must implement a solution in which all the EC2 instances share up-to-date website content with the least possible lag time.
Which solution meets these requirements?
A solutions architect must implement a solution in which all the EC2 instances share up-to-date website content with the least possible lag time.
Which solution meets these requirements?
Update the EC2 user data in the Auto Scaling group lifecycle policy to copy the website assets from the EC2 instance that was launched most recently. Configure the ALB to make changes to the website assets only in the newest EC2 instance.
Copy the website assets to an Amazon Elastic File System (Amazon EFS) file system. Configure each EC2 instance to mount the EFS file system locally. Configure the website hosting application to reference the website assets that are stored in the EFS file system.
Copy the website assets to an Amazon S3 bucket. Ensure that each EC2 instance downloads the website assets from the S3 bucket to the attached Amazon Elastic Block Store (Amazon EBS) volume. Run the S3 sync command once each hour to keep files up to date.
Restore an Amazon Elastic Block Store (Amazon EBS) snapshot with the website assets. Attach the EBS snapshot as a secondary EBS volume when a new EC2 instance is launched. Configure the website hosting application to reference the website assets that are stored in the secondary EBS volume.

A company is building a web-based application running on Amazon EC2 instances in multiple Availability Zones. The web application will provide access to a repository of text documents totaling about 900 TB in size. The company anticipates that the web application will experience periods of high demand. A solutions architect must ensure that the storage component for the text documents can scale to meet the demand of the application at all times. The company is concerned about the overall cost of the solution.
Which storage solution meets these requirements MOST cost-effectively?
Which storage solution meets these requirements MOST cost-effectively?
Amazon Elastic Block Store (Amazon EBS)
Amazon Elastic File System (Amazon EFS)
Amazon Elasticsearch Service (Amazon ES)
Amazon S3

A company is building a website that relies on reading and writing to an Amazon DynamoDB database. The traffic associated with the website predictably peaks during business hours on weekdays and declines overnight and during weekends. A solutions architect needs to design a cost-effective solution that can handle the load.
What should the solutions architect do to meet these requirements?
What should the solutions architect do to meet these requirements?
Enable DynamoDB Accelerator (DAX) to cache the data.
Enable Multi-AZ replication for the DynamoDB database.
Enable DynamoDB auto scaling when creating the tables.
Enable DynamoDB On-Demand capacity allocation when creating the tables.

A company is building its web application by using containers on AWS. The company requires three instances of the web application to run at all times. The application must be highly available and must be able to scale to meet increases in demand.
Which solution meets these requirements?
Which solution meets these requirements?
Use the AWS Fargate launch type to create an Amazon Elastic Container Service (Amazon ECS) cluster. Create a task definition for the web application. Create an ECS service that has a desired count of three tasks.
Use the Amazon EC2 launch type to create an Amazon Elastic Container Service (Amazon ECS) cluster that has three container instances in one Availability Zone. Create a task definition for the web application. Place one task for each container instance.
Use the AWS Fargate launch type to create an Amazon Elastic Container Service (Amazon ECS) cluster that has three container instances in three different Availability Zones. Create a task definition for the web application. Create an ECS service that has a desired count of three tasks.
Use the Amazon EC2 launch type to create an Amazon Elastic Container Service (Amazon ECS) cluster that has one container instance in two different Availability Zones. Create a task definition for the web application. Place two tasks on one container instance. Place one task on the remaining container instance.

A company is concerned that two NAT instances in use will no longer be able to support the traffic needed for the company's application. A solutions architect wants to implement a solution that is highly available fault tolerant, and automatically scalable.
What should the solutions architect recommend?
What should the solutions architect recommend?
Remove the two NAT instances and replace them with two NAT gateways in the same Availability Zone.
Use Auto Scaling groups with Network Load Balancers for the NAT instances in different Availability Zones.
Remove the two NAT instances and replace them with two NAT gateways in different Availability Zones.
Replace the two NAT instances with Spot Instances in different Availability Zones and deploy a Network Load Balancer.

A company is creating an architecture for a mobile app that requires minimal latency for its users. The company's architecture consists of Amazon EC2 instances behind an Application Load Balancer running in an Auto Scaling group. The EC2 instances connect to Amazon RDS. Application beta testing showed there was a slowdown when reading the data. However the metrics indicate that the EC2 instances do not cross any CPU utilization thresholds.
How can this issue be addressed?
How can this issue be addressed?
Reduce the threshold for CPU utilization in the Auto Scaling group.
Replace the Application Load Balancer with a Network Load Balancer.
Add read replicas for the RDS instances and direct read traffic to the replica.
Add Multi-AZ support to the RDS instances and direct read traffic to the new EC2 instance.
