292.While protecting the link between a company's VPC and its on-premises data center, a Security Engineer issued a ping command to an Amazon EC2 instance from an on-premises server (IP address 203.0.113.12). (IP address 172.31.16.139). The ping command returned an empty string. In the VPC's flow log, the following information was found: 2 123456789010 eni-1235b8ca 203.0.113.12 172.31.16.139 0 0 1 4 336 1432917027 1432917142 ACCEPT OK 2 123456789010 eni-1235b8ca 172.31.16.139 203.0.113.12 0 0 1 4 336 1432917094 1432917142 REJECT OK What needs be done to enable the ping to function properly? A. In the security group of the EC2 instance, allow inbound ICMP traffic. B. In the security group of the EC2 instance, allow outbound ICMP traffic. C. In the VPC's NACL, allow inbound ICMP traffic. D. In the VPC's NACL, allow outbound ICMP traffic.
293.A business has hundreds of Amazon Web Services accounts and a centralized Amazon S3 bucket that is used to gather AWS CloudTrail logs for all of these accounts. A security engineer want to develop a solution that would allow the firm to do ad hoc searches against its CloudTrail logs going back three years to the time the trails were originally activated in the company's AWS account. How might the business achieve this with the least administrative overhead possible? A. Run an Amazon EMR cluster that uses a MapReduce job to examine the CloudTrail trails. B. Use the events history feature of the CloudTrail console to query the CloudTrail trails. C. Write an AWS Lambda function to query the CloudTrail trails. Configure the Lambda function to be executed whenever a new file is created in the CloudTrail S3 bucket. D. Create an Amazon Athena table that looks at the S3 bucket the CloudTrail trails are being written to. Use Athena to run queries against the trails.
294.An business wishes to be notified when an illegal Amazon EC2 instance running in its VPC conducts a network port scan against other instances running in the VPC. When the Security team conducts internal testing in a separate account utilizing pre-approved third-party scanners from the AWS Marketplace, the Security team additionally gets various Amazon GuardDuty notifications from Amazon CloudWatch alerting on the Security team's test activities. How can the security team disable notifications for permitted security testing while getting alerts for unauthorized activity? A. Use a filter in AWS CloudTrail to exclude the IP addresses of the Security team's EC2 instances. B. Add the Elastic IP addresses of the Security team's EC2 instances to a trusted IP list in Amazon GuardDuty. C. Install the Amazon Inspector agent on the EC2 instances that the Security team uses. D. Grant the Security team's EC2 instances a role with permissions to call Amazon GuardDuty API operations.
295.AWS Lambda function was abused to change data, and a Security Engineer must determine who called the function and what output was generated. The Engineer is unable to locate any Lambda function logs in Amazon CloudWatch Logs. Which of the following best describes the absence of logs? A. The execution role for the Lambda function did not grant permissions to write log data to CloudWatch Logs. B. The Lambda function was executed by using Amazon API Gateway, so the logs are not stored in CloudWatch Logs. C. The execution role for the Lambda function did not grant permissions to write to the Amazon S3 bucket where CloudWatch Logs stores the logs. D. The version of the Lambda function that was executed was not current.
296.A business has a strong policy against the use of root credentials. The company's security team want to be notified immediately if root credentials are used to access the AWS Management Console. How should the security team accomplish this objective? A. Use AWS Lambda to periodically query AWS CloudTrail for console login events and send alerts using Amazon Simple Notification Service (Amazon SNS). B. Use Amazon EventBridge (Amazon CloudWatch Events) to monitor console logins and direct them to Amazon Simple Notification Service (Amazon SNS). C. Use Amazon Athena to query AWS SSO logs and send alerts using Amazon Simple Notification Service (Amazon SNS) for root login events. D. Configure AWS Resource Access Manager to review the access logs and send alerts using Amazon Simple Notification Service (Amazon SNS).
297.The Security Engineer is provided with the following requirements for an application that will operate on Amazon EC2 and will be controlled through AWS CloudFormation templates and EC2 Auto Scaling groups: -Ensure that the EC2 instances are booted up and configured to connect to a backend database. -Ensure that database credentials are securely managed. -Ensure that all database credentials retrievals are recorded. Which of the following methods is the MOST EFFECTIVE for meeting these requirements? A. Pass databases credentials to EC2 by using CloudFormation stack parameters with the property set to true. Ensure that the instance is configured to log to Amazon CloudWatch Logs. B. Store database passwords in AWS Systems Manager Parameter Store by using SecureString parameters. Set the IAM role for the EC2 instance profile to allow access to the parameters. C. Create an AWS Lambda that ingests the database password and persists it to Amazon S3 with server-side encryption. Have the EC2 instances retrieve the S3 object on startup, and log all script invocations to syslog. D. Write a script that is passed in as UserData so that it is executed upon launch of the EC2 instance. Ensure that the instance is configured to log to Amazon CloudWatch Logs.
298.A development team has requested assistance with setting IAM roles and rules in a newly created AWS account. The team that is using the account anticipates having hundreds of master keys and does not want to maintain access control for client master keys (CMKs). Which of the following will enable the team to control AWS KMS permissions using IAM without having to change individual key policies? A. The account's CMK key policy must allow the account's IAM roles to perform KMS EnableKey. B. Newly created CMKs must have a key policy that allows the root principal to perform all actions. C. Newly created CMKs must allow the root principal to perform the kms CreateGrant API operation. D. Newly created CMKs must mirror the IAM policy of the KMS key administrator.
300.A security engineer is creating a new Amazon Web Services (AWS) account. The engineer has been tasked with monitoring the company's AWS account on a continuous basis, employing automated compliance tests based on AWS best practices and the Center for Internet Security's (CIS) AWS Foundations Benchmarks. How might the security engineer do this via the use of Amazon Web Services (AWS)? A. Enable AWS Config and set it to record all resources in all Regions and global resources. Then enable AWS Security Hub and confirm that the CIS AWS Foundations compliance standard is enabled. B. Enable Amazon Inspector and configure it to scan all Regions for the CIS AWS Foundations Benchmarks. Then enable AWS Security Hub and configure it to ingest the Amazon Inspector findings. C. Enable Amazon Inspector and configure it to scan all Regions for the CIS AWS Foundations Benchmarks. Then enable AWS Shield in all Regions to protect the account from DDoS attacks. D. Enable AWS Config and set it to record all resources in all Regions and global resources. Then enable Amazon Inspector and configure it to enforce CIS AWS Foundations Benchmarks using AWS Config rules.
