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 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 analyst attempted to troubleshoot the monitoring of suspicious security group changes. The analyst was told that there is an Amazon CloudWatch alarm in place for these AWS CloudTrail log events. The analyst tested the monitoring setup by making a configuration change to the security group but did not receive any alerts.

Which of the following troubleshooting steps should the analyst perform?

A.
Ensure that CloudTrail and S3 bucket access logging is enabled for the analyst's AWS account.
Answers
A.
Ensure that CloudTrail and S3 bucket access logging is enabled for the analyst's AWS account.
B.
Verify that a metric filter was created and then mapped to an alarm. Check the alarm notification action.
Answers
B.
Verify that a metric filter was created and then mapped to an alarm. Check the alarm notification action.
C.
Check the CloudWatch dashboards to ensure that there is a metric configured with an appropriate dimension for security group changes.
Answers
C.
Check the CloudWatch dashboards to ensure that there is a metric configured with an appropriate dimension for security group changes.
D.
Verify that the analyst's account is mapped to an IAM policy that includes permissions for cloudwatch:GetMetricStatistics and cloudwatch:ListMetrics.
Answers
D.
Verify that the analyst's account is mapped to an IAM policy that includes permissions for cloudwatch:GetMetricStatistics and cloudwatch:ListMetrics.
Suggested answer: B

Explanation:

The correct answer is B because it checks the configuration of the CloudWatch alarm that is supposed to monitor the CloudTrail log events. The analyst should verify that a metric filter was created to extract the relevant information from the log events, such as the event name, source, and user identity.The analyst should also verify that the metric filter was mapped to an alarm that triggers when a certain threshold is reached, and that the alarm notification action is set up correctly to send alerts to the analyst1.

The other options are incorrect because they do not address the issue of the CloudWatch alarm not working as expected. Option A is incorrect because CloudTrail and S3 bucket access logging are not related to the monitoring of security group changes.CloudTrail logs the API calls made to AWS services, and S3 bucket access logging records the requests made to the bucket2.Option C is incorrect because CloudWatch dashboards are used to display metrics and alarms in a graphical way, but they do not affect the functionality of the alarm3. Option D is incorrect because the IAM policy permissions for cloudwatch:GetMetricStatistics and cloudwatch:ListMetrics are not required to monitor the CloudTrail log events.These permissions are used to retrieve the statistics and list of metrics for a given namespace4.
