Question 56

A company has stored 200 TB of backup files in Amazon S3. The files are in a vendor-proprietary format. The Solutions Architect needs to use the vendor's proprietary file conversion software to retrieve the files from their Amazon S3 bucket, transform the files to an industry-standard format, and re-upload the files back to Amazon S3. The solution must minimize the data transfer costs.
Which of the following options can satisfy the given requirement?

A.Deploy the EC2 instance in a different Region. Install the conversion software on the instance. Perform data transformation and re-upload it to Amazon S3.
B.Install the file conversion software in Amazon S3. Use S3 Batch Operations to perform data transformation.
C.Deploy the EC2 instance in the same Region as Amazon S3. Install the file conversion software on the instance. Perform data transformation and re-upload it to Amazon S3.
D.Export the data using AWS Snowball Edge device. Install the file conversion software on the device. Transform the data and re-upload it to Amazon S3.

Correct Answer: C

Amazon S3 is object storage built to store and retrieve any amount of data from anywhere on the Internet. It's a simple storage service that offers industry-leading durability, availability, performance, security, and virtually unlimited scalability at very low costs. Amazon S3 is also designed to be highly flexible. Store any type and amount of data that you want; read the same piece of data a million times or only for emergency disaster recovery; build a simple FTP application or a sophisticated web application.

You pay for all bandwidth into and out of Amazon S3, except for the following:
- Data transferred in from the Internet.
- Data transferred out to an Amazon EC2 instance, when the instance is in the same AWS Region as the S3 bucket (including to a different account in the same AWS region).
- Data transferred out to Amazon CloudFront.
To minimize the data transfer charges, you need to deploy the EC2 instance in the same Region as Amazon S3. Take note that there is no data transfer cost between S3 and EC2 in the same AWS Region.
Install the conversion software on the instance to perform data transformation and re-upload the data to Amazon S3.
Hence, the correct answer is: Deploy the EC2 instance in the same Region as Amazon S3. Install the file conversion software on the instance. Perform data transformation and re-upload it to Amazon S3.
The option that says: Install the file conversion software in Amazon S3. Use S3 Batch Operations to perform data transformation is incorrect because it is not possible to install the software in Amazon S3.
The S3 Batch Operations just runs multiple S3 operations in a single request. It can't be integrated with your conversion software.
The option that says: Export the data using AWS Snowball Edge device. Install the file conversion software on the device. Transform the data and re-upload it to Amazon S3 is incorrect. Although this is possible, it is not mentioned in the scenario that the company has an on-premises data center. Thus, there's no need for Snowball.
The option that says: Deploy the EC2 instance in a different Region. Install the file conversion software on the instance. Perform data transformation and re-upload it to Amazon S3 is incorrect because this approach wouldn't minimize the data transfer costs. You should deploy the instance in the same Region as Amazon S3.

Question 57

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?

A.Create an IAM role that grants access to the S3 bucket. Attach the role to the EC2 instances.
B.Create an IAM policy that grants access to the S3 bucket. Attach the policy to the EC2 instances.
C.Create an IAM group that grants access to the S3 bucket. Attach the group to the EC2 instances.
D.Create an IAM user that grants access to the S3 bucket. Attach the user account to the EC2 instances.

Question 58

A company hosts a website on Amazon EC2 instances behind an Application Load Balancer (ALB). The website serves static content. Website traffic is increasing. The company wants to minimize the website hosting costs.
Which solution will meet these requirements?

A.Move the website to an Amazon S3 bucket. Configure an Amazon CloudFront distribution for the S3 bucket.
B.Move the website to an Amazon S3 bucket. Configure an Amazon ElastiCache cluster for the S3 bucket.
C.Move the website to AWS Amplify. Configure an ALB to resolve to the Amplify website.
D.Move the website to AWS Amplify. Configure EC2 instances to cache the website.

Question 59

A company uses Amazon S3 as its data lake. The company has a new partner that must use SFTP to upload data files A solutions architect needs to implement a highly available SFTP solution that minimizes operational overhead.
Which solution will meet these requirements?

A.Use AWS Transfer Family to configure an SFTP-enabled server with a publicly accessible endpoint Choose the S3 data lake as the destination
B.Use Amazon S3 File Gateway as an SFTP server Expose the S3 File Gateway endpoint URL to the new partner Share the S3 File Gateway endpoint with the new partner
C.Launch an Amazon EC2 instance in a private subnet in a VPC. Instruct the new partner to upload files to the EC2 instance by using a VPN. Run a cron job script on the EC2 instance to upload files to the S3 data lake
D.Launch Amazon EC2 instances in a private subnet in a VPC. Place a Network Load Balancer (NLB) in front of the EC2 instances. Create an SFTP listener port for the NLB Share the NLB hostname with the new partner Run a cron job script on the EC2 instances to upload files to the S3 data lake.

Correct Answer: A

This option is the most cost-effective and simple way to enable SFTP access to the S3 data lake. AWS Transfer Family is a fully managed service that supports secure file transfers over SFTP, FTPS, and FTP protocols. You can create an SFTP-enabled server with a public endpoint and associate it with your S3 bucket. You can also use AWS Identity and Access Management (IAM) roles and policies to control access to your S3 data lake. The service scales automatically to handle any volume of file transfers and provides high availability and durability. You do not need to provision, manage, or patch any servers or load balancers.
Option B is not correct because Amazon S3 File Gateway is not an SFTP server. It is a hybrid cloud storage service that provides a local file system interface to S3. You can use it to store and retrieve files as objects in S3 using standard file protocols such as NFS and SMB. However, it does not support SFTP protocol, and it requires deploying a file gateway appliance on-premises or on EC2.
Option C is not cost-effective or scalable because it requires launching and managing an EC2 instance in a private subnet and setting up a VPN connection for the new partner. This would incur additional costs for the EC2 instance, the VPN connection, and the data transfer. It would also introduce complexity and security risks to the solution. Moreover, it would require running a cron job script on the EC2 instance to upload files to the S3 data lake, which is not efficient or reliable.
Option D is not cost-effective or scalable because it requires launching and managing multiple EC2 instances in a private subnet and placing a NLB in front of them. This would incur additional costs for the EC2 instances, the NLB, and the data transfer. It would also introduce complexity and security risks to the solution. Moreover, it would require running a cron job script on the EC2 instances to upload files to the S3 data lake, which is not efficient or reliable. Reference:
