57) A Company has a running Web Application Server in the N. Virginia region and the server has a large size EBS volume of approximately 500 GB, and to see the demand of business, the company needs to migrate the server from the current region to another AWS account's London location. Which is the best way to migrate the server from the current location to the London region? What information does the AWS administrator require about AWS A/C?

The best way to migrate the server from the N. Virginia region to another AWS account's London location is as follows:

1) Create an Amazon Machine Image (AMI) of the server that is currently running in the N. Virginia region.

2) Once the AMI is created, the AWS administrator will need the 12-digit account number of the AWS account in the London location. This account number is required for copying the AMI from one AWS account to another.

3) After obtaining the account number, copy the AMI into the London region associated with the second AWS account. In the London region, launch an instance using the copied AMI.

4) Verify that the new instance is running and fully operational in the London region. Ensure that all configurations and data have been successfully transferred.

5) Once the instance in the London region is confirmed to be working correctly, you can proceed to terminate the server in the N. Virginia region.

This migration process ensures that the web application server is moved from one AWS region to another AWS account's region without any significant disruption, and it's a reliable way to handle the migration.

58) A company currently operates a web application backed by an Amazon RDS MySQL database. It has automated backups that are run daily and are not encrypted. A security audit requires future backups to be encrypted and unencrypted backups to be destroyed. The company will make at least one encrypted backup before destroying the old backups. What should be done to enable encryption for future backups?

In order to enable encryption for future backups of the Amazon RDS MySQL database and satisfy the security audit requirements, the following steps should be taken:

1) Create a snapshot of the existing database used by the organisation.

2) Copy the snapshot to create an encrypted snapshot. This will ensure that future backups are encrypted.

3) After the encrypted snapshot is successfully created, restore the database from this encrypted snapshot.

By following these steps, the company will have enabled encryption for future backups. Moreover, they will also have created at least one encrypted backup before destroying the old, unencrypted backups. Thus, the security audit requirements can be met easily. This approach ensures that data remains secure and compliant with encryption standards.

59) A client reports that they wanted to see an audit log of any changes made to AWS resources in their account. What can the client do to achieve this?

In order to create an audit log of AWS resource changes in their account, the client should enable AWS CloudTrail and set up log delivery to an Amazon S3 bucket. This action records all API calls, ensuring a detailed and secure audit trail for monitoring and auditing AWS resource modifications.
