A developer needs to export the contents of several Amazon DynamoDB tables into Amazon S3 buckets to comply with company data regulations. The developer uses the AWS CLI to runcommands to export from each table to the proper S3 bucket. The developer sets up AWS credentials correctly and grants resources appropriate permissions. However, the exports of some tables fail.
What should the developer do to resolve this issue?

• A.Ensure that DynamoDB Accelerator (DAX) is enabled.
• B.Ensure that point-in-time recovery is enabled on the DynamoDB tables.
• C.Ensure that DynamoDB streaming is enabled for the tables.
• D.Ensure that the target S3 bucket is in the same AWS Region as the DynamoDB table.

A solutions architect is designing the storage architecture for a new web application used for storing and viewing engineering drawings. All application components will be deployed on the AWS infrastructure. The application design must support caching to minimize the amount of time that users wait for the engineering drawings to load. The application must be able to store petabytes of data.
Which combination of storage and caching should the solutions architect use?

• A.Amazon Elastic Block Store (Amazon EBS) volumes with Amazon CloudFront
• B.AWS Storage Gateway with Amazon ElastiCache
• C.Amazon S3 Glacier Deep Archive with Amazon ElastiCache
• D.Amazon S3 with Amazon CloudFront

A solutions architect needs to connect a company's corporate network to its VPC to allow on-premises access to its AWS resources. The solution must provide encryption of all trafficbetween the corporate network and the VPC at the network layer and the session layer. The solution also must provide security controls to prevent unrestricted access between AWS and the on-premises systems.
Which solution meets these requirements?

• A.Configure AWS Transit Gateway to connect to the VPC. Configure route table entries to direct traffic from on premises to the VPC. Configure instance security groups and network ACLs to allow only required traffic from on premises.
• B.Configure AWS Direct Connect to connect to the VPC. Configure the VPC route tables to allow and deny traffic between AWS and on premises as required.
• C.Create an IAM policy to allow access to the AWS Management Console only from a defined set of corporate IP addresses Restrict user access based on job responsibility by using an IAM policy and roles
• D.Configure AWS Site-to-Site VPN to connect to the VPC. Configure route table entries to direct traffic from on premises to the VPC. Configure instance security groups and network ACLs to allow only required traffic from on premises.

A company recently migrated its application to AWS. The application runs on Amazon EC2 Linux instances in an Auto Scaling group across multiple Availability Zones. The application stores data in an Amazon Elastic File System (Amazon EFS) file system that uses EFS Standard-Infrequent Access storage. The application indexes the company's files, and the index is stored in an Amazon RDS database.
The company needs to optimize storage costs with some application and services changes.
Which solution will meet these requirements MOST cost-effectively?

• A.Create an Amazon S3 bucket that uses S3 Glacier Flexible Retrieval. Copy all files to the S3 bucket.Update the application to use Amazon S3 API to store and retrieve files as standard retrievals.
• B.Deploy Amazon FSx for Windows File Server file shares. Update the application to use CIFS protocol to store and retrieve files.
• C.Create an Amazon S3 bucket that uses an Intelligent-Tiering lifecycle policy. Copy all files to the S3 bucket. Update the application to use Amazon S3 API to store and retrieve files.
• D.Deploy Amazon FSx for OpenZFS file system shares. Update the application to use the new mount point to store and retrieve files.

A company runs Amazon EC2 instances as web servers. Peak traffic occurs at two predictable times each day.
The web servers remain mostly idle during the rest of the day.
A solutions architect must manage the web servers while maintaining fault tolerance in the most cost-effective way.
Which solution will meet these requirements?

• A.Purchase Reserved Instances to ensure peak capacity at all times.
• B.Use a cron job to stop the EC2 instances when traffic demand is low.
• C.Use an EC2 Auto Scaling group to scale the instances based on demand.
• D.Use a script to vertically scale the EC2 instances during peak demand.
