AWS Certified Solutions Architect - Associate (SAA-C03) Questions and Answers

Question 185

A company hosts an application that allows authorized users to upload and download documents. The application uses Amazon EC2 instances and an Amazon Elastic File System (Amazon EFS) file system.

The company plans to deploy the application into a second AWS Region. The company will launch a new EFS file system and a new set of EC2 instances in the second Region. A solutions architect must develop a highly available and fault-tolerant solution to establish two-way synchronization across the Regions.

Which solution will meet these requirements?

Options:

A.

Create an Amazon EFS VPC endpoint for the original EFS file system in the second Region. Mount both the original and the new EFS file system to the new set of EC2 instances in the second Region. Configure an rsync cron job to run every 5 minutes.

B.

Set up EFS replication between the two EFS file systems. Set the new file system as the source. Set the original file system in the first Region as the destination. Turn off overwrite protection for the destination file system.

C.

Set up one AWS DataSync agent in each Region. Configure Amazon EFS VPC endpoints, EFS transfer locations, and EFS transfer tasks with opposite directions on the two DataSync agents.

D.

Mount the EFS file system in the second Region to the new set of EC2 instances in the second Region. Use AWS Transfer Family to establish SFTP access to the EFS file system in the original Region. Configure an rsync cron job to run every 5 minutes.

Question 186

A company runs multiple applications in multiple AWS accounts within the same organization in AWS Organizations. A content management system (CMS) runs on Amazon EC2 instances in a VPC. The CMS needs to access shared files from an Amazon Elastic File System (Amazon EFS) file system that is deployed in a separate AWS account. The EFS account is in a separate VPC.

Which solution will meet this requirement?

Options:

A.

Mount the EFS file system on the EC2 instances by using the EFS Elastic IP address.

B.

Enable VPC sharing between the two accounts. Use the EFS mount helper to mount the file system on the EC2 instances. Redeploy the EFS file system in a shared subnet.

C.

Configure AWS Systems Manager Run Command to mount the EFS file system on the EC2 instances.

D.

Install the amazon-efs-utils package on the EC2 instances. Add the mount target in the efs-config file. Mount the EFS file system by using the EFS access point.

Question 187

A company wants to isolate its workloads by creating an AWS account for each workload. The company needs a solution that centrally manages networking components for the workloads. The solution also must create accounts with automatic security controls (guardrails).

Which solution will meet these requirements with the LEAST operational overhead?

Options:

A.

Use AWS Control Tower to deploy accounts. Create a networking account that has a VPC with private subnets and public subnets. Use AWS Resource Access Manager (AWS RAM) to share the subnets with the workload accounts.

B.

Use AWS Organizations to deploy accounts. Create a networking account that has a VPC with private subnets and public subnets. Use AWS Resource Access Manager (AWS RAM) to share the subnets with the workload accounts.

C.

Use AWS Control Tower to deploy accounts. Deploy a VPC in each workload account. Configure each VPC to route through an inspection VPC by using a transit gateway attachment.

D.

Use AWS Organizations to deploy accounts. Deploy a VPC in each workload account. Configure each VPC to route through an inspection VPC by using a transit gateway attachment.

Question 188

A company uses an Amazon EC2 instance to handle requests for a public web application. The application routes traffic to multiple application pages by using URL paths.

The company begins to experience large surges of traffic at unpredictable times. The traffic surges cause the web application to experience issues and to occasionally become unavailable.

The company needs to make the web application more scalable to handle sudden increases in traffic.

Which solution will meet this requirement?

Options:

A.

Create an Amazon Machine Image (AMI) of the web application instance. Use the AMI to create an Auto Scaling group of EC2 instances that has a minimum capacity of two. Create an Application Load Balancer. Set the Auto Scaling group as the target group.

B.

Create a Docker image of the application. Use Amazon Elastic Container Service (Amazon ECS) to create an Auto Scaling ECS cluster. Enable managed scaling. Create a Network Load Balancer. Set the ECS cluster as the target group.

C.

Create an Amazon Machine Image (AMI) of the web application instance. Use the AMI to create two more web application instances in separate Availability Zones. Update the website DNS record to refer to all three instances.

D.

Create an Application Load Balancer (ALB). Set the web application instance as the target. Create an Amazon CloudWatch alarm based on ALB traffic metrics. Configure the alert to activate when traffic spikes.
