A company has automated the nightly retraining ot its machine learning models by using AWS Step Functions. The workflow consists of multiple steps that use AWS Lambda. Each step can fail for various reasons, and any failure causes a failure of the overall workflow.
A review reveals that the retraining has failed multiple nights in a row without the company noticing the failure. A solutions architect needs to improve the workflow so that notifications are sent for all types of failures in the retraining process.
Which combination of steps should the solutions architect take to meet these requirements? (Select THREE.)

1. A. Create an Amazon Simple Notification Service {Amazon SNS) topic with a subscription of type"Email" that targets the team's mailing list.
2. B. Create a task named "Email" that forwards the input arguments to the SNS topic
3. C. Add a Catch field to all Tas
4. D. Ma
5. E. and Parallel states that have a statement of "ErrorEquals": [ "states.all" ] and "Next": "Email".
6. F. Add a new email address to Amazon Simple Email Service (Amazon SES). Verify the email address.
7. G. Create a task named "Email" that forwards the input arguments to the SES email address
8. H. Add a Catch field to all Task, Map, and Parallel states that have a statement of "ErrorEquals": [ "states.Bun time" ] and "Next": "Email".

Correct Answer: BCD

An AWS partner company is building a service in AWS Organizations using Its organization named org. This service requires the partner company to have access to AWS resources in a customer account, which is in a separate organization named org2 The company must establish least privilege security access using an API or command line tool to the customer account
What is the MOST secure way to allow org1 to access resources h org2?

1. A. The customer should provide the partner company with their AWS account access keys to log in and perform the required tasks
2. B. The customer should create an IAM user and assign the required permissions to the IAM user The customer should then provide the credentials to the partner company to log In and perform the required tasks.
3. C. The customer should create an IAM role and assign the required permissions to the IAM rol
4. D. The partner company should then use the IAM rote's Amazon Resource Name (ARN) when requesting access to perform the required tasks
5. E. The customer should create an IAM rote and assign the required permissions to the IAM rot
6. F. The partner company should then use the IAM rote's Amazon Resource Name (ARN). Including the external ID in the IAM role's trust pokey, when requesting access to perform the required tasks

Correct Answer: D

A company has built a high performance computing (HPC) cluster in AWS for a tightly coupled workload that generates a large number of shared files stored in Amazon EFS. The cluster was performing well when the number of Amazon EC2 instances in the cluster was 100. However, when the company increased the cluster size to 1,000 EC2 instances, overall performance was well below expectations
Which collection of design choices should a solutions architect make to achieve the maximum performance from the HPC cluster? (Select THREE.)

1. A. Ensure the HPC cluster is launched within a single Availability Zone.
2. B. Launch the EC2 instances and attach elastic network interfaces in multiples of four.
3. C. Select EC2 instance types with an Elastic Fabric Adapter (EFA) enabled
4. D. Ensure the cluster is launched across multiple Availability Zones.
5. E. Replace Amazon EFS with multiple Amazon EBS volumes in a RAID array.
6. F. Replace Amazon EFS with Amazon FSx for Lustre.

Correct Answer: ACE

A development team has created a new flight tracker application that provides near-real-time data to users. The application has a front end that consists of an Application Load Balancer (ALB) in front of two large Amazon EC2 instances in a single Availability Zone. Data is stored in a single Amazon RDS MySQL DB instance. An Amazon Route 53 DNS record points to the ALB.
Management wants the development team to improve the solution to achieve maximum reliability with the least amount of operational overhead.
Which set of actions should the team take?

1. A. Create RDS MySQL read replica
2. B. Deploy the application to multiple AWS Region
3. C. Use a Route 53 latency-based routing policy to route to the application.
4. D. Configure the DB instance as Multi-A
5. E. Deploy the application to two additional EC2 instances in different Availability Zones behind an ALB.
6. F. Replace the DB instance with Amazon DynamoDB global table
7. G. Deploy the application in multiple AWS Region
8. H. Use a Route 53 latency-based routing policy to route to the application.
9. I. Replace the DB instance with Amazon Aurora with Aurora Replica
10. J. Deploy the application to mulliple smaller EC2 instances across multiple Availability Zones in an Auto Scaling group behind an ALB.

Correct Answer: D
Multi AZ ASG + ALB + Aurora = Less over head and automatic scaling

A North American company with headquarters on the East Coast is deploying a new web application running on Amazon EC2 in the us-east-1 Region. The application should dynamically scale to meet user demand and maintain resiliency. Additionally, the application must have disaster recovery capabilities in an active-passive configuration with the us-west-1 Region.
Which steps should a solutions architect take after creating a VPC in the us-east-1 Region?

1. A. Create a VPC in the us-west-1 Regio
2. B. Use inter-Region VPC peering to connect both VPC
3. C. Deploy an Application Load Balancer (ALB) spanning multiple Availability Zones (AZs) to the VPC in theus-east-1 Regio
4. D. Deploy EC2 instances across multiple AZs in each Region as part of an Auto Scaling group spanning both VPCs and served by the ALB.
5. E. Deploy an Application Load Balancer (ALB) spanning multiple Availability Zones (AZs) to the VPC inthe us-east-1 Regio
6. F. Deploy EC2 instances across multiple AZs as part of an Auto Scaling group served by the AL
7. G. Deploy the same solution to the us-west-1 Region Create an Amazon Route 53 record set with a failover routing policy and health checks enabled to provide high availability across both Regions.
8. H. Create a VPC in the us-west-1 Regio
9. I. Use inter-Region VPC peering to connect both VPCs Deploy an Application Load Balancer (ALB) that spans both VPCs Deploy EC2 instances across multiple Availability Zones as part of an Auto Scaling group in each VPC served by the AL
10. J. Create an Amazon Route 53 record that points to the ALB.
11. K. Deploy an Application Load Balancer (ALB) spanning multiple Availability Zones (AZs) to the VPC in the us-east-1 Regio
12. L. Deploy EC2 instances across multiple AZs as part of an Auto Scaling group served by the AL
13. M. Deploy the same solution to the us-west-1 Regio
14. N. Create separate Amazon Route 53 records in each Region that point to the ALB in the Regio
15. O. Use Route 53 health checks to provide high availability across both Regions.

Correct Answer: B
A new web application in a active-passive DR mode. a Route 53 record set with a failover routing policy.
