A company is implementing a new business application. The application runs on two Amazon EC2 instances and uses an Amazon S3 bucket for document storage. A solutions architect needs to ensure that the EC2 instances can access the S3 bucket.
What should the solutions architect do to meet this requirement?

1. A. Create an IAM role that grants access to the S3 bucke
2. B. Attach the role to the EC2 instances.
3. C. Create an IAM policy that grants access to the S3 bucke
4. D. Attach the policy to the EC2 instances.
5. E. Create an IAM group that grants access to the S3 bucke
6. F. Attach the group to the EC2 instances.
7. G. Create an IAM user that grants access to the S3 bucke
8. H. Attach the user account to the EC2 instances.

A transaction processing company has weekly scripted batch jobs that run on Amazon EC2 instances. The EC2 instances are in an Auto Scaling group. The number of transactions can vary but the beseline CPU utilization that is noted on each run is at least 60%. The company needs to provision the capacity 30 minutes before the jobs run.
Currently engineering complete this task by manually modifying the Auto Scaling group parameters. The company does not have the resources to analyze the required capacity trends for the Auto Scaling group counts. The company needs an automated way to modify the Auto Scaling group’s capacity.
Which solution will meet these requiements with the LEAST operational overhead?

1. A. Ceate a dynamic scalling policy for the Auto Scaling grou
2. B. Configure the policy to scale based on the CPU utilization metric to 60%.
3. C. Create a scheduled scaling polcy for the Auto Scaling grou
4. D. Set the appropriate desired capacity, minimum capacity, and maximum capacit
5. E. Set the recurrence to weekl
6. F. Set the start time to 30 minute
7. G. Before the batch jobs run.
8. H. Create a predictive scaling policy for the Auto Scaling grou
9. I. Configure the policy to scale based on forecas
10. J. Set the scaling metric to CPU utilizatio
11. K. Set the target value for the metric to 60%. In the Policy, set the instances to pre-launch 30 minutes before the jobs run.
12. L. Create an Amazon EventBridge event to invoke an AWS Lamda function when the CPU utilization metric value for the Auto Scaling group reaches 60%. Configure the Lambda function to increase the Auto Scaling group’s desired capacity and maximum capacity by 20%.

Correct Answer: C

A company has a dynamic web application hosted on two Amazon EC2 instances. The company has its own SSL certificate, which is on each instance to perform SSL termination.
There has been an increase in traffic recently, and the operations team determined that SSL encryption and decryption is causing the compute capacity of the web servers to reach their maximum limit.
What should a solutions architect do to increase the application's performance?

1. A. Create a new SSL certificate using AWS Certificate Manager (ACM) install the ACM certificate on each instance
2. B. Create an Amazon S3 bucket Migrate the SSL certificate to the S3 bucket Configure the EC2 instances to reference the bucket for SSL termination
3. C. Create another EC2 instance as a proxy server Migrate the SSL certificate to the new instance and configure it to direct connections to the existing EC2 instances
4. D. Import the SSL certificate into AWS Certificate Manager (ACM) Create an Application Load Balancer with an HTTPS listener that uses the SSL certificate from ACM

Correct Answer: D
https://aws.amazon.com/certificate-manager/:
"With AWS Certificate Manager, you can quickly request a certificate, deploy it on ACM-integrated AWS resources, such as Elastic Load Balancers, Amazon CloudFront distributions, and APIs on API Gateway, and let AWS Certificate Manager handle certificate renewals. It also enables you to create private certificates for
your internal resources and manage the certificate lifecycle centrally."

A solutions architect is using Amazon S3 to design the storage architecture of a new digital media application. The media files must be resilient to the loss of an Availability Zone Some files are accessed frequently while other files are rarely accessed in an unpredictable pattern. The solutions architect must minimize the costs of storing and retrieving the media files.
Which storage option meets these requirements?

1. A. S3 Standard
2. B. S3 Intelligent-Tiering
3. C. S3 Standard-Infrequent Access {S3 Standard-IA)
4. D. S3 One Zone-Infrequent Access (S3 One Zone-IA)

Correct Answer: B
S3 Intelligent-Tiering - Perfect use case when you don't know the frequency of access or irregular patterns of usage.
Amazon S3 offers a range of storage classes designed for different use cases. These include S3 Standard for general-purpose storage of frequently accessed data; S3 Intelligent-Tiering for data with unknown or changing access patterns; S3 Standard-Infrequent Access (S3 Standard-IA) and S3 One Zone-Infrequent Access (S3 One Zone-IA) for long-lived, but less frequently accessed data; and Amazon S3 Glacier (S3 Glacier) and Amazon S3 Glacier Deep Archive (S3 Glacier Deep Archive) for long-term archive and digital preservation. If you have data residency requirements that can’t be met by an existing AWS Region, you can use the S3 Outposts storage class to store your S3 data on-premises. Amazon S3 also offers capabilities to manage your data throughout its lifecycle. Once an S3 Lifecycle policy is set, your data will automatically transfer to a different storage class without any changes to your application.

A company collects data from thousands of remote devices by using a RESTful web services application that runs on an Amazon EC2 instance. The EC2 instance receives the raw data, transforms the raw data, and stores all the data in an Amazon S3 bucket. The number of remote devices will increase into the millions soon. The company needs a highly scalable solution that minimizes operational overhead.
Which combination of steps should a solutions architect take to meet these requirements9 (Select TWO.)

1. A. Use AWS Glue to process the raw data in Amazon S3.
2. B. Use Amazon Route 53 to route traffic to different EC2 instances.
3. C. Add more EC2 instances to accommodate the increasing amount of incoming data.
4. D. Send the raw data to Amazon Simple Queue Service (Amazon SOS). Use EC2 instances to process the data.
5. E. Use Amazon API Gateway to send the raw data to an Amazon Kinesis data strea
6. F. Configure Amazon Kinesis Data Firehose to use the data stream as a source to deliver the data to Amazon S3.

Correct Answer: AE
"RESTful web services" => API Gateway.
"EC2 instance receives the raw data, transforms the raw data, and stores all the data in an Amazon S3 bucket"
=> GLUE with (Extract - Transform - Load)
