A company's engineering team is developing a new application that creates IAM Key Management Service (IAM KMS) CMK grants for users immediately after a grant IS created users must be able to use the CMK tu encrypt a 512-byte payload. During load testing, a bug appears |intermittently where AccessDeniedExceptions are occasionally triggered when a user rst attempts to encrypt using the CMK Which solution should the c0mpany's security specialist recommend'?
A company Is planning to use Amazon Elastic File System (Amazon EFS) with its on-premises servers. The company has an existing IAM Direct Connect connection established between its on-premises data center and an IAM Region Security policy states that the company's on-premises firewall should only have specific IP addresses added to the allow list and not a CIDR range. The company also wants to restrict access so that only certain data center-based servers have access to Amazon EFS How should a security engineer implement this solution''
A company is implementing new compliance requirements to meet customer needs. According to the new requirements the company must not use any Amazon RDS DB instances or DB clusters that lack encryption of the underlying storage. The company needs a solution that will generate an email alert when an unencrypted DB instance or DB cluster is created. The solution also must terminate the unencrypted DB instance or DB cluster. Which solution will meet these requirements in the MOST operationally efficient manner?
A developer has created an AWS Lambda function in a company's development account. The Lambda function requires the use of an AWS Key Management Service (AWS KMS) customer managed key that exists in a security account that the company's security team controls. The developer obtains the ARN of the KMS key from a previous Lambda function in the development account. The previous Lambda function had been working properly with the KMS key. When the developer uses the ARN and tests the new Lambda function an error message states that access is denied to the KMS key in the security account. The developer tests the previous Lambda function that uses the same KMS key and discovers that the previous Lambda function still can encrypt data as expected. A security engineer must resolve the problem so that the new Lambda function in the development account can use the KMS key from the security account. Which combination of steps should the security engineer take to meet these requirements? (Select TWO.)
A company has two AWS accounts: Account A and Account B. Account A has an IAM role that IAM users in Account B assume when they need to upload sensitive documents to Amazon S3 buckets in Account A. A new requirement mandates that users can assume the role only if they are authenticated with multi-factor authentication (MFA). A security engineer must recommend a solution that meets this requirement with minimum risk and effort. Which solution should the security engineer recommend?
An international company has established a new business entity in South Kore a. The company also has established a new AWS account to contain the workload for the South Korean region. The company has set up the workload in the new account in the ap-northeast-2 Region. The workload consists of three Auto Scaling groups of Amazon EC2 instances. All workloads that operate in this Region must keep system logs and application logs for 7 years. A security engineer must implement a solution to ensure that no logging data is lost for each instance during scaling activities. The solution also must keep the logs for only the required period of 7 years. Which combination of steps should the security engineer take to meet these requirements? (Choose three.)
A security engineer must use AWS Key Management Service (AWS KMS) to design a key management solution for a set of Amazon Elastic Block Store (Amazon EBS) volumes that contain sensitive data. The solution needs to ensure that the key material automatically expires in 90 days. Which solution meets these criteria?
A Development team has built an experimental environment to test a simple stale web application It has built an isolated VPC with a private and a public subnet. The public subnet holds only an Application Load Balancer a NAT gateway, and an internet gateway. The private subnet holds ail of the Amazon EC2 instances There are 3 different types of servers Each server type has its own Security Group that limits access lo only required connectivity. The Security Groups nave both inbound and outbound rules applied Each subnet has both inbound and outbound network ACls applied to limit access to only required connectivity Which of the following should the team check if a server cannot establish an outbound connection to the internet? (Select THREE.)

A company wants to prevent SSH access through the use of SSH key pairs for any Amazon Linux 2 Amazon EC2 instances in its AWS account. However, a system administrator occasionally will need to access these EC2 instances through SSH in an emergency. For auditing purposes, the company needs to record any commands that a user runs in an EC2 instance.

What should a security engineer do to configure access to these EC2 instances to meet these requirements?

A.
Use the EC2 serial console Configure the EC2 serial console to save all commands that are entered to an Amazon S3 bucket. Provide the EC2 instances with an IAM role that allows the EC2 serial console to access Amazon S3. Configure an IAM account for the system administrator. Provide an IAM policy that allows the IAM account to use the EC2 serial console.

D.
Use AWS Systems Manager Session Manager Configure Session Manager to save all commands that are entered in a session to an Amazon S3 bucket. Provide the EC2 instances with an IAM role that allows Systems Manager to manage the EC2 instances. Configure an IAM account for the system administrator Provide an IAM policy that allows the IAM account to use Session Manager.

Suggested answer: D

Explanation:

Open the AWS Systems Manager console at https://console.aws.amazon.com/systems-manager/. In the navigation pane, choose Session Manager. Choose the Preferences tab, and then choose Edit. Select the check box next to Enable under S3 logging. (Recommended) Select the check box next to Allow only encrypted S3 buckets. With this option turned on, log data is encrypted using the server-side encryption key specified for the bucket. If you don't want to encrypt the log data that is sent to Amazon S3, clear the check box. You must also clear the check box if encryption isn't allowed on the S3 bucket.
