Question 1

A company needs to follow security best practices to deploy resources from an AWS CloudFormation template. The CloudFormation template must be able to configure sensitive database credentials. The company already uses AWS Key Management Service (AWS KMS) and AWS Secrets Manager. Which solution will meet the requirements?

A : Use a dynamic reference in the CloudFormation template to reference the database credentials in Secrets Manager.

B : Use a parameter in the CloudFormation template to reference the database credentials. Encrypt the CloudFormation template by using AWS KMS.

C : Use a SecureString parameter in the CloudFormation template to reference the database credentials in Secrets Manager.

D : Use a SecureString parameter in the CloudFormation template to reference an encrypted value in AWS KMS

Answer: A

Question 2

A security engineer is investigating a malware infection that has spread across a set of Amazon EC2 instances. A key indicator of the compromise is outbound traffic on TCP port 2905 to a set of command and control hosts on the internet. The security engineer creates a network ACL rule that denies the identified outbound traffic. The security engineer applies the network ACL rule to the subnet of the EC2 instances. The security engineer must identify any EC2 instances that are trying to communtcate on TCP port 2905. Which solution will identify the affected EC2 instances with the LEAST operational effort?

A : Create a Network Access Scope in Amazon VPC Network Access Analyzer. Use the Network Access Scope to identify EC2 instances that try to send traffic to TCP port 2905.

B : Enable VPC flow logs for the VPC where the affected EC2 instances are located Configure the flow logs to capture rejected traffic. In the flow logs, search for REJECT records that have a destination TCP port of 2905.

C : Enable Amazon GuardDuty Create a custom GuardDuty IP list to create a finding when an EC2 instance tries to communicate with one of the command and control hosts. Use Amazon Detective to identify the EC2 instances that initiate the communication.

D : Create a firewall in AWS Network Firewall. Attach the firewall to the subnet of the EC2 instances. Create a custom rule to identify and log traffic from the firewall on TCP port 2905. Create an Amazon CloudWatch Logs metric filter to identify firewall logs that reference traffic on TCP port 2905.

Answer: B

Question 3

A company wants to start processing sensitive data on Amazon EC2 instances. The company will use Amazon CloudWatch Logs to monitor, store, and access log files from the EC2 instances. The company's developers use CloudWatch Logs for troubleshooting. A security engineer must implement a solution that prevents the developers from viewing the sensitive data The solution must automatically apply to any new log groups that are created in the account in the future. Which solution will meet these requirements?

A : Create a CloudWatch Logs account-wide data protection policy. Specify the appropriate data identifiers for the policy. Ensure that the developers do not have the logs:Unmask 1AM permission.

B : Export the CloudWatch Logs data to an Amazon S3 bucket. Set up automated discovery by using Amazon Macie on the S3 bucket. Create a custom data identifier for the sensitive data. Remove the developers' access to CloudWatch Logs. Grant permissions for the developers to view the exported log data in Amazon S3.

C : Export the CloudWatch Logs data to an Amazon S3 bucket. Set up automated discovery by using Amazon Macie on the S3 bucket. Specify the appropriate managed data identifiers. Remove the developers' access to CloudWatch Logs. Grant permissions for the developers to view the exported log data in Amazon S3.

D : Create a CloudWatch Logs data protection policy for each log group. Specify the appropriate data identifiers for the policy. Ensure that the developers do not have the logsiUnmask 1AM permission

Answer: A

Question 4

A company has AWS accounts in an organization in AWS Organizations. The company needs to install a corporate software package on all Amazon EC2 instances for all the accounts in the organization. A central account provides base AMIs for the EC2 instances. The company uses AWS Systems Manager for software inventory and patching operations. A security engineer must implement a solution that detects EC2 instances ttjat do not have the required software. The solution also must automatically install the software if the software is not present. Which solution will meet these requirements?

A : Provide new AMIs that have the required software pre-installed. Apply a tag to the AMIs to indicate that the AMIs have the required software. Configure an SCP that allows new EC2 instances to be launched only if the instances have the tagged AMIs. Tag all existing EC2 instances.

B : Configure a custom patch baseline in Systems Manager Patch Manager. Add the package name for the required software to the approved packages list. Associate the new patch baseline with all EC2 instances. Set up a maintenance window for software deployment.

C : Centrally enable AWS Config. Set up the ec2-managedinstance-applications-required AWS Config rule for all accounts Create an Amazon EventBridge rule that reacts to AWS Config events. Configure the EventBridge rule to invoke an AWS Lambda function that uses Systems Manager Run Command to install the required software.

D : Create a new Systems Manager Distributor package for the required software. Specify the download location. Select all EC2 instances in the different accounts. Install the software by using Systems Manager Run Command.

Answer: C

Question 5

A company needs to use HTTPS when connecting to its web applications to meet compliance requirements. These web applications run in Amazon VPC on Amazon EC2 instances behind an Application Load Balancer (ALB). A security engineer wants to ensure that the load balancer win only accept connections over port 443. even if the ALB is mistakenly configured with an HTTP listener Which configuration steps should the security engineer take to accomplish this task?

A :

Create a security group with a rule that denies Inbound connections from 0.0.0 0/0 on port 00. Attach this security group to the ALB to overwrite more permissive rules from the ALB's default security group

B :

Create a network ACL that denies inbound connections from 0 0.0.0/0 on port 80 Associate the network ACL with the VPC s internet gateway

C :

Create a network ACL that allows outbound connections to the VPC IP range on port 443 only. Associate the network ACL with the VPC's internet gateway.

D :

Create a security group with a single inbound rule that allows connections from 0.0.0 0/0 on port 443. Ensure this security group is the only one associated with the ALB
