1. 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?

A) S3 One Zone-Infrequent Access
B) S3 Intelligent-Tiering
C) S3 Standard
D) S3 Standard-Infrequent Access



2. A company's web application is using multiple Linux Amazon Ec2 instance and storing data on Amazon EBS volumes. The company is looking for a solution to increase the resiliency of the application in case of a failure and to provide storage that complies with atomicity, consistency, isolation, and durability (ACID).What should a solutions architect do to meet these requirements?

A) Create an Application Load Balancer with Auto Scaling group across multiple Availability Zones. Store data on Amazon EFS and mount a target on each instance.
B) Launch the application on EC2 instances in each Availability Zone. Attach EBS volumes to each EC2 instance.
C) Create an Application Load Balancer with Auto Scaling group across multiple Availability Zones. Store data using Amazon S3 One Zone-Infrequent Access (S3 One Zone-IA)
D) Create an Application Load Balancer with Auto Scaling groups across multiple Availability Zones. Mount an instance store on each EC2 instance.



3. A solutions architect is moving the static content from a public website hosted on Amazon EC2 instances to an Amazon S3 bucket. An Amazon CloudFront distribution will be used to deliver the static assets. The security group used by the EC2 instances restricts access to a limited set of IP ranges. Access to the static content should be similarly restricted.Which combination of steps will meet these requirements? Select two(Select 2answers)

A) Create a new security group that includes the same IP restrictions that exist in the current EC2 security group. Associate this new security group with the CloudFront distribution.
B) Create an AWS WAF web ACL that includes the same IP restrictions that exist in the EC2 security group. Associate this new web ACL with the CloudFront distribution
C) Create a new IAM role and associate the role with the distribution. Change the permissions either on the S3 bucket or on the files within the S3 bucket so that only the newly created IAM role has read and download.
D) Create an origin access identity (OAI) and associate it with the distribution. Change the permissions in the bucket policy so that only the OAI can read the objects.
E) Create a new security group that includes the same IP restrictions that exist in the current EC2 security group. Associate this new security group with the S3 bucket hosting the static content.


4. A bicycle sharing company is developing a multi-tier architecture to track the location of its bicycles during peak operating hours. The company wants to use these data points in its existing analytics platform. A solutions architect must determine the most viable multi-tier option to support this architecture. The data points must be accessible from the REST API.Which action meets these requirements for storing and retrieving location data?

A) Use Amazon Athena with Amazon S3
B) Use Amazon QuickSight with Amazon Redshift
C) Use Amazon API Gateway with AWS Lambda
D) Use Amazon API Gateway with Amazon Kinesis Data Analytics.



5. A company must re-evaluate its need for the Amazon EC2 instances it currently has provisioned in an Auto Scaling group. At present, the Auto Scaling group is configured for a minimum of two instances and a maximum of four instances across two Availability Zones. A solutions architect reviewed Amazon CLoudWatch metrics and found that CPU utilization is consistently low for all the EC2 instances.What should the solutions architect recommend to maximize utilization while ensuring the application remains fault tolerant?

A) Modify the Auto Scaling group scaling policy to scale in and out based on a higher CPU utilization metric
B) Remove some EC2 instances to increase the utilization of remaining instances
C) Increase the Amazon Elastic Block Store capacity of instance with less CPU utilization
D) Create a new launch configuration that uses smaller instance types. Update the existing Auto Scaling group
