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 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 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 is deploying an Amazon EC2-based application. The application will include a custom health-checking component that produces health status data in JSON format. A Security Engineer must implement a secure solution to monitor application availability in near-real time by analyzing the hearth status data. Which approach should the Security Engineer use?

Question 319 - SCS-C02 discussion

Report
Export

A company hosts an application on Amazon EC2 instances. The application also uses Amazon S3 and Amazon Simple Queue Service (Amazon SQS). The application is behind an Application Load Balancer (ALB) and scales with AWS Auto Scaling.

The company's security policy requires the use of least privilege access, which has been applied to all existing AWS resources. A security engineer needs to implement private connectivity to AWS services.

Which combination of steps should the security engineer take to meet this requirement? (Select THREE.)

Answers
D.

E.
Modify the endpoint policies on all VPC endpoints. Specify the SQS and S3 resources that the application uses
Answers
E.
Modify the endpoint policies on all VPC endpoints. Specify the SQS and S3 resources that the application uses
F.
Configure a connection to Amazon S3 through AWS Firewall Manager
Answers
F.
Configure a connection to Amazon S3 through AWS Firewall Manager
Suggested answer: A, C, E

Explanation:

The correct answer is A, C, and E because they provide the most secure and efficient way to implement private connectivity to AWS services. Using interface VPC endpoints for Amazon SQS and gateway VPC endpoints for Amazon S3 allows the application to access these services without using public IP addresses or internet gateways. Modifying the endpoint policies on all VPC endpoints enables the security engineer to specify the SQS and S3 resources that the application uses and restrict access to other resources.

The other options are incorrect because they do not provide private connectivity to AWS services or they introduce unnecessary complexity or cost. Option B is incorrect because AWS Transit Gateway is used to connect multiple VPCs and on-premises networks, not to connect to AWS services. Option D is incorrect because modifying the IAM role applied to the EC2 instances is not sufficient to allow outbound traffic to the interface endpoints. The security group and route table associated with the interface endpoints also need to be configured. Option F is incorrect because AWS Firewall Manager is used to centrally manage firewall rules across multiple accounts and resources, not to connect to AWS services.
