Amazon AWS Certified DevOps Engineer - Professional Sample Questions (Q161-Q166):

NEW QUESTION # 161
A company's DevOps team manages a set of AWS accounts that are in an organization in AWS Organizations The company needs a solution that ensures that all Amazon EC2 instances use approved AMIs that the DevOps team manages. The solution also must remediate the usage of AMIs that are not approved The individual account administrators must not be able to remove the restriction to use approved AMIs.
Which solution will meet these requirements?

A. Create an AWS Lambda function that processes AWS CloudTrail events for Amazon EC2 Configure the Lambda function to send a notification to an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe the DevOps team to the SNS topic. Deploy the Lambda function in each account in the organization Create an Amazon EventBridge rule in each account Configure the EventBridge rules to react to AWS CloudTrail events for Amazon EC2 and to invoke the Lambda function.
B. Use AWS CloudFormation StackSets to deploy an Amazon EventBridge rule to each account. Configure the rule to react to AWS CloudTrail events for Amazon EC2 and to send a notification to an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe the DevOps team to the SNS topic
C. Enable AWS Config across the organization Create a conformance pack that uses the approved -amis-by-id AWS Config managed rule with the list of approved AMIs. Deploy the conformance pack across the organization. Configure the rule to run the AWS-StopEC2lnstance AWS Systems Manager Automation runbook for the noncompliant EC2 instances.
D. Use AWS CloudFormation StackSets to deploy the approved-amis-by-id AWS Config managed rule to each account. Configure the rule with the list of approved AMIs. Configure the rule to run the the AWS-StopEC2lnstance AWS Systems Manager Automation runbook for the noncompliant EC2 instances.

Answer: C

Explanation:
Enable AWS Config Across the Organization:
AWS Config provides a detailed view of the configuration of AWS resources in your AWS account. It can be used to assess, audit, and evaluate the configurations of your resources.
Enabling AWS Config across the organization ensures that all accounts are monitored for compliance.
Create a Conformance Pack Using the approved-amis-by-id AWS Config Managed Rule:
A conformance pack is a collection of AWS Config rules and remediation actions that can be easily deployed across an organization.
The approved-amis-by-id managed rule checks whether running instances are using approved AMIs.
Deploy the Conformance Pack Across the Organization:
Deploying the conformance pack across the organization ensures that all accounts adhere to the policy of using only approved AMIs.
The conformance pack can be deployed via the AWS Management Console, CLI, or SDKs.
Configure the Rule to Run the AWS-StopEC2Instance AWS Systems Manager Automation Runbook for Non-Compliant EC2 Instances:
The AWS-StopEC2Instance runbook can be configured to automatically stop any EC2 instances that are found to be non-compliant (i.e., not using approved AMIs).
This remediation action ensures that any unauthorized instances are promptly stopped, enforcing the policy without manual intervention.
By following these steps, the solution ensures that all EC2 instances across the organization use approved AMIs, and any non-compliant instances are remediated automatically.

NEW QUESTION # 162
A company has an application that uses an Amazon API Gateway REST API, AWS Lambda functions, and an Amazon DynamoDB table. The application currently runs in a single AWS Region. The company wants to make the application highly available across two Regions. User traffic must be routed to the Region that provides the least latency.
Which combination of steps will meet these requirements? (Select THREE.)

A. Create health checks in Amazon Route 53. Create DNS records that include a failover routing policy.
B. Create copies of the REST API and the Lambda functions in a second Region.
C. Create a global secondary index for the DynamoDB table.
D. Create DNS records in Amazon Route 53 that include a multivalue answer routing policy.
E. Create health checks in Amazon Route 53. Create DNS records that include a latency routing policy.
F. Create a global table replica of the DynamoDB table in a second Region.

Answer: B,E,F

Explanation:
To achieve multi-Region high availability for a serverless API-based application, the architecture must be duplicated in the second Region and supported by a multi-Region data layer and appropriate DNS routing. Option A provides the required multi-Region data layer using DynamoDB global tables, which replicate data automatically and asynchronously between Regions. This allows reads and writes in either Region and prevents cross-Region latency bottlenecks.
Option C ensures that the compute components-API Gateway REST API and AWS Lambda functions-are deployed in both Regions. Each Region operates independently, providing true active-active redundancy and allowing Route 53 to route traffic directly to either Region without dependency on the other.
Option E selects Route 53 latency-based routing, which directs each user to the Region with the lowest round-trip latency. This meets the requirement to route traffic based on the Region providing the best response time rather than only providing active-passive failover.
Option D (failover routing) supports active-standby topologies, not active-active. Option B creates a global secondary index, which does not provide multi-Region replication. Option F (multivalue routing) distributes traffic randomly and does not account for latency or Region placement.
Thus, combining DynamoDB global tables, duplicated serverless architecture, and latency-based routing fully satisfies the requirements.

NEW QUESTION # 163
A company has enabled all features for its organization in AWS Organizations. The organization contains 10 AWS accounts. The company has turned on AWS CloudTrail in all the accounts. The company expects the number of AWS accounts in the organization to increase to 500 during the next year. The company plans to use multiple OUs for these accounts.
The company has enabled AWS Config in each existing AWS account in the organization. A DevOps engineer must implement a solution that enables AWS Config automatically for all future AWS accounts that are created in the organization.
Which solution will meet this requirement?

A. In the organization's management account, create an AWS CloudFormation stack set to enable AWS Config. Configure the stack set to deploy automatically when an account is created through Organizations.
B. In the organization's management account, create an Amazon EventBridge rule that reacts to a CreateAccount API call. Configure the rule to invoke an AWS Lambda function that enables trusted access to AWS Config for the organization.
C. In the organization's management account, create an Amazon EventBridge rule that reacts to a CreateAccount API call. Configure the rule to invoke an AWS Systems Manager Automation runbook to enable AWS Config for the account.
D. In the organization's management account, create an SCP that allows the appropriate AWS Config API calls to enable AWS Config. Apply the SCP to the root-level OU.

Answer: A

NEW QUESTION # 164
A developer is maintaining a fleet of 50 Amazon EC2 Linux servers. The servers are part of an Amazon EC2 Auto Scaling group, and also use Elastic Load Balancing for load balancing.
Occasionally, some application servers are being terminated after failing ELB HTTP health checks. The developer would like to perform a root cause analysis on the issue, but before being able to access application logs, the server is terminated.
How can log collection be automated?

A. Use Auto Scaling lifecycle hooks to put instances in a Pending:Wait state. Create an Amazon CloudWatch alarm for EC2 Instance Terminate Successful and trigger an AWS Lambda function that invokes an SSM Run Command script to collect logs, push them to Amazon S3, and complete the lifecycle action once logs are collected.
B. Use Auto Scaling lifecycle hooks to put instances in a Terminating:Wait state. Create an AWS Config rule for EC2 Instance-terminate Lifecycle Action and trigger a step function that invokes a script to collect logs, push them to Amazon S3, and complete the lifecycle action once logs are collected.
C. Use Auto Scaling lifecycle hooks to put instances in a Terminating:Wait state. Create an Amazon CloudWatch subscription filter for EC2 Instance Terminate Successful and trigger a CloudWatch agent that invokes a script to collect logs, push them to Amazon S3, and complete the lifecycle action once logs are collected.
D. Use Auto Scaling lifecycle hooks to put instances in a Terminating:Wait state. Create an Amazon EventBridge rule for EC2 Instance-terminate Lifecycle Action and trigger an AWS Lambda function that invokes an SSM Run Command script to collect logs, push them to Amazon S3, and complete the lifecycle action once logs are collected.

NEW QUESTION # 165
An Amazon EC2 instance is running in a VPC and needs to download an object from a restricted Amazon S3 bucket. When the DevOps engineer tries to download the object, an AccessDenied error is received, What are the possible causes tor this error? (Select TWO,)

A. There is an error in the IAM role configuration.
B. The 53 bucket default encryption is enabled.
C. S3 Versioning is enabled.
D. The object has been moved to S3 Glacier.
E. There is an error in the S3 bucket policy.

Answer: A,E

Explanation:
Explanation
These are the possible causes for the AccessDenied error because they affect the permissions to access the S3 object from the EC2 instance. An S3 bucket policy is a resource-based policy that defines who can access the bucket and its objects, and what actions they can perform. An IAM role is an identity that can be assumed by an EC2 instance to grant it permissions to access AWS services and resources. If there is an error in the S3 bucket policy or the IAM role configuration, such as a missing or incorrect statement, condition, or principal, then the EC2 instance may not have the necessary permissions to download the object from the S3 bucket .
