1. A company runs multiple Amazon EC2 Linux instances in a VPC with applications that use a hierarchical directory structure. The applications need to rapidly and concurrently read and write to shared storage. How can this be archived?

A) Create an Amazon S3 bucket and permit access from all the EC2 instances in the VPC
B) Create a file system on an Amazon EBS Provisioned IOPS SSD (101) volume. Attach the volume to all the EC2 instances
C) Create file systems on Amazon EBS volumes attached to each EC2 instance. Synchronize the Amazon EBS volumes across the different EC2 instances.
D) Create an Amazon EFS file system and mount it from each EC2 instance,



2. An ecommerce company is running a multi-tier application on AWS. The front-end and backend tiers both run on Amazon EC2, and the database runs on Amazon RDS for MySQL. The backend tier communicates with the RDS instance. There are frequent calls to return identical datasets from the database that are causing performance slowdowns.Which action should be taken to improve the performance of the backend?

A) Implement Amazon ElastiCache to cache the large datasets.
B) Implement Amazon SNS to store the database calls.
C) Implement Amazon Kinesis Data Firehose to stream the calls to the database.
D) Implement an RDS for MySQL read replica to cache database calls.



3. A company is migrating to the AWS Cloud. A file server is the first workload to migrate. Users must be able to access the file share using the Server Message Block (SMB) protocol.Which AWS managed service meets these requirements?

A) Amazon FSx
B) Amazon EBS
C) Amazon S3
D) Amazon EC2



4. A company must migrate 20 TB of data from a data center to the AWS Cloud within 30 days. The company's network bandwidth is limited to 15 Mbps and cannot exceed 70% utilization. What should a solutions architect do to meet these requirements?

A) Use AWS Snowball.
B) Use a secure VPN connection.
C) Use AWS DataSync.
D) Use Amazon S3 Transfer Acceleration.



5. A healthcare company stores highly sensitive patient records. Compliance requires that multiple copies be stored in different locations. Each record must be stored for 7 years. The company has a service level agreement (SLA) to provide records to government agencies immediately for the first 30 days and then within 4 hours of a request thereafter.What should a solutions architect recommend?

A) Use Amazon S3 with cross-Region replication enabled. After 30 days, transition the data to Amazon S3 Glacier using lifecycle policy.
B) Use Amazon S3 with cross-origin resource sharing (CORS) enabled. After 30 days, transition the data to Amazon S3 Glacier Deep Archive using a lifecycle policy.
C) Use Amazon S3 with cross-Region replication enabled. After 30 days, transition the data to Amazon S3 Glacier Deep Achieve using a lifecycle policy.
D) Use Amazon S3 with cross-origin resource sharing (CORS) enabled. After 30 days, transition the data to Amazon S3 Glacier using a lifecycle policy.
