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?
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?
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 company is operating a website using Amazon CloudFornt. CloudFront servers some content from Amazon S3 and other from web servers running EC2 instances behind an Application. Load Balancer (ALB). Amazon DynamoDB is used as the data store. The company already uses IAM Certificate Manager (ACM) to store a public TLS certificate that can optionally secure connections between the website users and CloudFront. The company has a new requirement to enforce end-to-end encryption in transit. Which combination of steps should the company take to meet this requirement? (Select THREE.)
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.)

Question 266 - SCS-C02 discussion

A company has an organization with SCPs in AWS Organizations. The root SCP for the organization is as follows:

The company's developers are members of a group that has an IAM policy that allows access to Amazon Simple Email Service (Amazon SES) by allowing ses:* actions. The account is a child to an OU that has an SCP that allows Amazon SES. The developers are receiving a not-authorized error when they try to access Amazon SES through the AWS Management Console.

Which change must a security engineer implement so that the developers can access Amazon SES?

A.
Add a resource policy that allows each member of the group to access Amazon SES.
Answers
A.
Add a resource policy that allows each member of the group to access Amazon SES.
B.
Add a resource policy that allows 'Principal': {'AWS': 'arn:aws:iam::account-number:group/Dev'}.
Answers
B.
Add a resource policy that allows 'Principal': {'AWS': 'arn:aws:iam::account-number:group/Dev'}.
C.
Remove the AWS Control Tower control (guardrail) that restricts access to Amazon SES.
Answers
C.
Remove the AWS Control Tower control (guardrail) that restricts access to Amazon SES.
D.
Remove Amazon SES from the root SCP.
Answers
D.
Remove Amazon SES from the root SCP.
Suggested answer: D

Explanation:

The correct answer is D. Remove Amazon SES from the root SCP.

This answer is correct because the root SCP is the most restrictive policy that applies to all accounts in the organization. The root SCP explicitly denies access to Amazon SES by using the NotAction element, which means that any action that is not listed in the element is denied. Therefore, removing Amazon SES from the root SCP will allow the developers to access it, as long as there are no other SCPs or IAM policies that deny it.

The other options are incorrect because:

A) Adding a resource policy that allows each member of the group to access Amazon SES is not a solution, because resource policies are not supported by Amazon SES1. Resource policies are policies that are attached to AWS resources, such as S3 buckets or SNS topics, to control access to those resources2. Amazon SES does not have any resources that can have resource policies attached to them.

B) Adding a resource policy that allows ''Principal'': {''AWS'': ''arn:aws:iam::account-number:group/Dev''} is not a solution, because resource policies do not support IAM groups as principals3. Principals are entities that can perform actions on AWS resources, such as IAM users, roles, or AWS accounts4. IAM groups are not principals, but collections of IAM users that share the same permissions5.

C) Removing the AWS Control Tower control (guardrail) that restricts access to Amazon SES is not a solution, because AWS Control Tower does not have any guardrails that restrict access to Amazon SES6. Guardrails are high-level rules that govern the overall behavior of an organization's accounts7. AWS Control Tower provides a set of predefined guardrails that cover security, compliance, and operations domains8.

1: Amazon Simple Email Service endpoints and quotas 2: Resource-based policies and IAM policies 3: Specifying a principal in a policy 4: Policy elements: Principal 5: IAM groups 6: AWS Control Tower guardrails reference 7: AWS Control Tower concepts 8: AWS Control Tower guardrails
