Cost of physical server hardware
Cost of physical server hardware
Cost of network management
Cost of network management
Suggested answer: A, D

Explanation:

The costs that the company will eliminate with this migration are the cost of application licensing and the cost of physical server hardware. The cost of application licensing is the fee that the company has to pay to use the software applications on its on-premises servers. The cost of physical server hardware is the expense that the company has to incur to purchase, maintain, and upgrade the servers and related equipment. By migrating to the AWS Cloud, the company can avoid these costs by using the AWS services and resources that are already licensed and managed by AWS.

Create an 1AM role with the required permissions. Attach the role to the administrative1AM user.
Create an 1AM role with the required permissions. Attach the role to the administrative1AM user.
Suggested answer: A

Explanation:

Creating an IAM role with the required permissions and attaching the role to the EC2 instance is the most operationally efficient solution to delegate permissions. An IAM role is an entity that defines a set of permissions for making AWS service requests. An IAM role can be assumed by an EC2 instance to access other AWS resources, such as Amazon S3 and Amazon DynamoDB, without having to store any credentials on the instance. This solution is more secure and scalable than using IAM users and their access keys. For more information, see [IAM Roles for Amazon EC2] and [Using an IAM Role to Grant Permissions to Applications Running on Amazon EC2 Instances].

Which encryption types can be used to protect objects at rest in Amazon S3? (Select TWO.)

Server-side encryption with AmazonS3 managed encryption keys (SSE-S3)
Server-side encryption with AmazonS3 managed encryption keys (SSE-S3)

SSL
Transparent Data Encryption (TDE)
Transparent Data Encryption (TDE)
Suggested answer: A, B

Explanation:

Server-side encryption with Amazon S3 managed encryption keys (SSE-S3) and server-side encryption with AWS KMS managed keys (SSE-KMS) are the encryption types that can be used to protect objects at rest in Amazon S3. Server-side encryption means that Amazon S3 encrypts the objects before saving them on disks and decrypts them when they are downloaded. SSE-S3 uses one master key per bucket that is managed by Amazon S3. SSE-KMS uses a customer master key (CMK) that is stored in AWS Key Management Service (AWS KMS) and provides additional benefits, such as audit trails and key rotation. For more information, see Protecting Data Using Server-Side Encryption and Protecting Data Using Encryption.
