Amazon AWS Certified DevOps Engineer - Professional Sample Questions (Q274-Q279):

NEW QUESTION # 274
A development team is using AWS CodeCommit to version control application code and AWS CodePipeline to orchestrate software deployments. The team has decided to use a remote main branch as the trigger for the pipeline to integrate code changes. A developer has pushed code changes to the CodeCommit repository, but noticed that the pipeline had no reaction, even after 10 minutes.
Which of the following actions should be taken to troubleshoot this issue?

Answer: B

Explanation:
Explanation
When you create a pipeline from CodePipeline during the step-by-step it creates a CloudWatch Event rule for a given branch and repo like this:
{
"source": [
"aws.codecommit"
],
"detail-type": [
"CodeCommit Repository State Change"
],
"resources": [
"arn:aws:codecommit:us-east-1:xxxxx:repo-name"
],
"detail": {
"event": [
"referenceCreated",
"referenceUpdated"
],
"referenceType": [
"branch"
],
"referenceName": [
"master"
]
}

NEW QUESTION # 275
A company is launching an application. The application must use only approved AWS services. The account that runs the application was created less than 1 year ago and is assigned to an AWS Organizations OU.
The company needs to create a new Organizations account structure. The account structure must have an appropriate SCP that supports the use of only services that are currently active in the AWS account.
The company will use AWS Identity and Access Management (IAM) Access Analyzer in the solution.
Which solution will meet these requirements?

Answer: D

Explanation:
To meet the requirements of creating a new Organizations account structure with an appropriate SCP that supports the use of only services that are currently active in the AWS account, the company should use the following solution:
* Create an SCP that allows the services that IAM Access Analyzer identifies. IAM Access Analyzer is a service that helps identify potential resource-access risks by analyzing resource-based policies in the AWS environment. IAM Access Analyzer can also generate IAM policies based on access activity in the AWS CloudTrail logs. By using IAM Access Analyzer, the company can create an SCP that grants only the permissions that are required for the application to run, and denies all other services. This way, the company can enforce the use of only approved AWS services and reduce the risk of unauthorized access12
* Create an OU for the account. Move the account into the new OU. An OU is a container for accounts within an organization that enables you to group accounts that have similar business or security requirements. By creating an OU for the account, the company can apply policies and manage settings for the account as a group. The company should move the account into the new OU to make it subject to the policies attached to the OU3
* Attach the new SCP to the new OU. Detach the default FullAWSAccess SCP from the new OU. An SCP is a type of policy that specifies the maximum permissions for an organization or organizational unit (OU). By attaching the new SCP to the new OU, the company can restrict the services that are available to all accounts in that OU, including the account that runs the application. The company should also detach the default FullAWSAccess SCP from the new OU, because this policy allows all actions on all AWS services and might override or conflict with the new SCP45 The other options are not correct because they do not meet the requirements or follow best practices. Creating an SCP that denies the services that IAM Access Analyzer identifies is not a good option because it might not cover all possible services that are not approved or required for the application. A deny policy is also more difficult to maintain and update than an allow policy. Creating an SCP that allows the services that IAM Access Analyzer identifies and attaching it to the organization's root is not a good option because it might affect other accounts and OUs in the organization that have different service requirements or approvals.
Creating an SCP that allows the services that IAM Access Analyzer identifies and attaching it to the management account is not a valid option because SCPs cannot be attached directly to accounts, only to OUs or roots.

NEW QUESTION # 276
A company uses an organization in AWS Organizations to manage multiple AWS accounts. The company has enabled all features for the organization. The member accounts under one OU contain S3 buckets that store sensitive data.
A DevOps engineer wants to ensure that only IAM principals from within the organization can access the S3 buckets in the OU.
Which solution will meet this requirement?

Answer: C

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
To restrict access to S3 buckets so that only IAM principals from within the AWS Organization can access them, anSCP(Service Control Policy) with conditions using the aws:PrincipalAccount or preferably aws:
PrincipalOrgID can be applied at the OU level.
* SCPs restrict the maximum permissions for IAM entities in member accounts and can be used to enforce access control policies across accounts.
* The aws:PrincipalAccount condition restricts access to principals from specific accounts, while aws:
PrincipalOrgID restricts based on the organization ID.
* IAM permissions boundaries (Option B) cannot be applied organization-wide and do not enforce restrictions across accounts.
* AWS RAM (Option C) is for sharing resources but does not restrict S3 bucket access based on organizational principals.
* There is no such thing as an RCP in AWS Organizations (Option D is invalid).
Reference:
AWS Organizations SCPs with Conditions:"Use SCPs with aws:PrincipalOrgID to restrict resource access to principals in your organization."(AWS Organizations SCP Conditions) S3 Bucket Policy Conditions for Organization:"Use the aws:PrincipalOrgID condition key in S3 bucket policies to restrict access to members of your organization."(S3 Bucket Policy Examples)


NEW QUESTION # 277
A company hired a penetration tester to simulate an internal security breach The tester performed port scans on the company's Amazon EC2 instances. The company's security measures did not detect the port scans.
The company needs a solution that automatically provides notification when port scans are performed on EC2 instances. The company creates and subscribes to an Amazon Simple Notification Service (Amazon SNS) topic.
What should the company do next to meet the requirement?

Answer: C

Explanation:
Ensure that Amazon GuardDuty is Enabled:
* Amazon GuardDuty is a threat detection service that continuously monitors for malicious activity and unauthorized behavior.
* It can detect port scans and generate findings for these events.
Create an Amazon CloudWatch Alarm for Detected EC2 and Port Scan Findings:
* Configure GuardDuty to monitor for port scans and other threats.
* Create a CloudWatch alarm that triggers when GuardDuty detects port scan activities.
Connect the Alarm to the SNS Topic:
* The CloudWatch alarm should be configured to send notifications to the SNS topic subscribed by the security team.
* This setup ensures that the security team receives near-real-time notifications when a port scan is detected on the EC2 instances.
Example configuration steps:
* Enable GuardDuty and ensure it is monitoring the relevant AWS accounts.
* Create a CloudWatch alarm:
{
"AlarmName": "GuardDutyPortScanAlarm",
"MetricName": "ThreatIntelIndicator",
"Namespace": "AWS/GuardDuty",
"Statistic": "Sum",
"Dimensions": [
{
"Name": "FindingType",
"Value": "Recon:EC2/Portscan"
}
],
"Period": 300,
"EvaluationPeriods": 1,
"Threshold": 1,
"ComparisonOperator": "GreaterThanOrEqualToThreshold",
"AlarmActions": ["arn:aws:sns:region:account-id:SecurityAlerts"]
}

NEW QUESTION # 278
A company's DevOps engineer is working in a multi-account environment. The company uses AWS Transit Gateway to route all outbound traffic through a network operations account. In the network operations account all account traffic passes through a firewall appliance for inspection before the traffic goes to an internet gateway.
The firewall appliance sends logs to Amazon CloudWatch Logs and includes event seventies of CRITICAL, HIGH, MEDIUM, LOW, and INFO. The security team wants to receive an alert if any CRITICAL events occur.
What should the DevOps engineer do to meet these requirements?

Answer: A

Explanation:
"The firewall appliance sends logs to Amazon CloudWatch Logs and includes event severities of CRITICAL, HIGH, MEDIUM, LOW, and INFO"
