A company has an AWS Lambda function that needs read access to an Amazon S3 bucket that is located in the same AWS account. Which solution will meet these requirement in the MOST secure manner?

1. A. Apply an S3 bucket pokey that grants road access to the S3 bucket
2. B. Apply an IAM role to the Lambda function Apply an IAM policy to the role to grant read access to the S3 bucket
3. C. Embed an access key and a secret key In the Lambda function's coda to grant the required IAM permissions for read access to the S3 bucket
4. D. Apply an IAM role to the Lambda functio
5. E. Apply an IAM policy to the role to grant read access to all S3 buckets In the account

Correct Answer: B

A company is moving its on-premises Oracle database to Amazon Aurora PostgreSQL. The database has several applications that write to the same tables. The applications need to be migrated one by one with a month in between each migration. Management has expressed concerns that the database has a high number of reads and writes. The data must be kept in sync across both databases throughout the migration.
What should a solutions architect recommend?

1. A. Use AWS DataSync for the initial migratio
2. B. Use AWS Database Migration Service (AWS DMS) to create a change data capture (CDC) replication task and a table mapping to select all tables.
3. C. Use AWS DataSync for the initial migratio
4. D. Use AWS Database Migration Service (AWS DMS) to create a full load plus change data capture (CDC) replication task and a table mapping to select all tables.
5. E. Use the AWS Schema Conversion Tool with AWS Database Migration Service (AWS DMS) using amemory optimized replication instanc
6. F. Create a full load plus change data capture (CDC) replication task and a table mapping to select all tables.
7. G. Use the AWS Schema Conversion Tool with AWS Database Migration Service (AWS DMS) using a compute optimized replication instanc
8. H. Create a full load plus change data capture (CDC) replication task and a table mapping to select the largest tables.

Correct Answer: C

A company offers a food delivery service that is growing rapidly. Because of the growth, the company’s order processing system is experiencing scaling problems during peak traffic hours. The current architecture includes the following:
• A group of Amazon EC2 instances that run in an Amazon EC2 Auto Scaling group to collect orders from the application
• Another group of EC2 instances that run in an Amazon EC2 Auto Scaling group to fulfill orders
The order collection process occurs quickly, but the order fulfillment process can take longer. Data must not be lost because of a scaling event.
A solutions architect must ensure that the order collection process and the order fulfillment process can both scale properly during peak traffic hours. The solution must optimize utilization of the company’s AWS resources.
Which solution meets these requirements?

1. A. Use Amazon CloudWatch metrics to monitor the CPU of each instance in the Auto Scaling groups.Configure each Auto Scaling group’s minimum capacity according to peak workload values.
2. B. Use Amazon CloudWatch metrics to monitor the CPU of each instance in the Auto Scaling groups.Configure a CloudWatch alarm to invoke an Amazon Simple Notification Service (Amazon SNS) topic that creates additional Auto Scaling groups on demand.
3. C. Provision two Amazon Simple Queue Service (Amazon SQS) queues: one for order collection and another for order fulfillmen
4. D. Configure the EC2 instances to poll their respective queu
5. E. Scale the Auto Scaling groups based on notifications that the queues send.
6. F. Provision two Amazon Simple Queue Service (Amazon SQS) queues: one for order collection and another for order fulfillmen
7. G. Configure the EC2 instances to poll their respective queu
8. H. Create a metric based on a backlog per instance calculatio
9. I. Scale the Auto Scaling groups based on this metric.

Correct Answer: D
The number of instances in your Auto Scaling group can be driven by how long it takes to process a message and the acceptable amount of latency (queue delay). The solution is to use a backlog per instance metric with the target value being the acceptable backlog per instance to maintain.

A solution architect needs to assign a new microsoft for a company’s application. Clients must be able to call an HTTPS endpoint to reach the micoservice. The microservice also must use AWS identity and Access Management (IAM) to authentication calls. The soltions architect will write the logic for this microservice by using a single AWS Lambda function that is written in Go 1.x.
Which solution will deploy the function in the in the MOST operationally efficient way?

1. A. Create an Amazon API Gateway REST AP
2. B. Configure the method to use the Lambda functio
3. C. Enable IAM authentication on the API.
4. D. Create a Lambda function URL for the functio
5. E. Specify AWS_IAM as the authentication type.
6. F. Create an Amazon CloudFront distributio
7. G. Deploy the function to Lambda@Edg
8. H. Integrate IAM authentication logic into the Lambda@Edge function.
9. I. Create an Amazon CloudFront distribuio
10. J. Deploy the function to CloudFront Function
11. K. Specify AWS_IAM as the authentication type.

Correct Answer: A

A company recently started using Amazon Aurora as the data store for its global ecommerce application When large reports are run developers report that the ecommerce application is performing poorly After reviewing metrics in Amazon CloudWatch, a solutions architect finds that the ReadlOPS and CPUUtilization metrics are spiking when monthly reports run.
What is the MOST cost-effective solution?

1. A. Migrate the monthly reporting to Amazon Redshift.
2. B. Migrate the monthly reporting to an Aurora Replica
3. C. Migrate the Aurora database to a larger instance class
4. D. Increase the Provisioned IOPS on the Aurora instance

Correct Answer: B

#Aurora.Replication.Replicas Aurora Replicas have two main purposes. You can issue queries to them to scale the read operations for your application. You typically do so by connecting to the reader endpoint of the cluster. That way, Aurora can spread the load for read-only connections across as many Aurora Replicas as you have in the cluster. Aurora Replicas also help to increase availability. If the writer instance in a cluster becomes unavailable, Aurora automatically promotes one of the reader instances to take its place as the new writer.
