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 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 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 company purchased a subscription to a third-party cloud security scanning solution that integrates with AWS Security Hub. A security engineer needs to implement a solution that will remediate the findings from the third-party scanning solution automatically. Which solution will meet this requirement?

Question 132 - SCS-C02 discussion

Export

A company has two VPCs in the same AWS Region and in the same AWS account Each VPC uses a CIDR block that does not overlap with the CIDR block of the other VPC One VPC contains AWS Lambda functions that run inside a subnet that accesses the internet through a NAT gateway. The Lambda functions require access to a publicly accessible Amazon Aurora MySQL database that is running in the other VPC

A security engineer determines that the Aurora database uses a security group rule that allows connections from the NAT gateway IP address that the Lambda functions use. The company's security policy states that no database should be publicly accessible.

What is the MOST secure way that the security engineer can provide the Lambda functions with access to the Aurora database?

A.
Move the Aurora database into a private subnet that has no internet access routes in the database's current VPC Configure the Lambda functions to use the Aurora database's new private IP address to access the database Configure the Aurora databases security group to allow access from the private IP addresses of the Lambda functions
Answers
A.
Move the Aurora database into a private subnet that has no internet access routes in the database's current VPC Configure the Lambda functions to use the Aurora database's new private IP address to access the database Configure the Aurora databases security group to allow access from the private IP addresses of the Lambda functions
B.
Establish a VPC endpoint between the two VPCs in the Aurora database's VPC configure a service VPC endpoint for Amazon RDS In the Lambda functions' VPC. configure an interface VPC endpoint that uses the service endpoint in the Aurora database's VPC Configure the service endpoint to allow connections from the Lambda functions.

C.
Establish an AWS Direct Connect interface between the VPCs Configure the Lambda functions to use a new route table that accesses the Aurora database through the Direct Connect interface Configure the Aurora database's security group to allow access from the Direct Connect interface IP address

C.
Establish an AWS Direct Connect interface between the VPCs Configure the Lambda functions to use a new route table that accesses the Aurora database through the Direct Connect interface Configure the Aurora database's security group to allow access from the Direct Connect interface IP address
D.
Move the Lambda functions into a public subnet in their VPC Move the Aurora database into a private subnet in its VPC Configure the Lambda functions to use the Aurora database's new private IP address to access the database Configure the Aurora database to allow access from the public IP addresses of the Lambda functions
Answers
D.
Move the Lambda functions into a public subnet in their VPC Move the Aurora database into a private subnet in its VPC Configure the Lambda functions to use the Aurora database's new private IP address to access the database Configure the Aurora database to allow access from the public IP addresses of the Lambda functions
Suggested answer: B

Explanation:

This option involves creating a VPC Endpoint between the two VPCs that allows private communication between them without going through the internet or exposing any public IP addresses. In this option, a VPC endpoint for Amazon RDS will be established, and an interface VPC endpoint will be created that points to the service endpoint in the Aurora database's VPC. This way, the Lambda functions can use the private IP address of the Aurora database to access it through the VPC endpoint without exposing any public IP addresses or allowing public internet access to the database.
