問題 #79
A company wants to deploy a workload on several hundred Amazon EC2 instances. The company will provision the EC2 instances in an Auto Scaling group by using a launch template.
The workload will pull files from an Amazon S3 bucket, process the data, and put the results into a different S3 bucket. The EC2 instances must have least-privilege permissions and must use temporary security credentials.
Which combination of steps will meet these requirements? (Select TWO.)

A. Create an IAM role that has the appropriate permissions for S3 buckets. Add the IAM role to an instance profile.
B. Update the launch template to include the IAM instance profile.
C. Create an IAM user that has the appropriate permissions for Amazon S3. Generate a secret key and token.
D. Create a trust anchor and profile. Attach the IAM role to the profile.
E. Update the launch template. Modify the user data to use the new secret key and token.

答案：A,B

解題說明：
Explanation
To meet the requirements of deploying a workload on several hundred EC2 instances with least-privilege permissions and temporary security credentials, the company should use an IAM role and an instance profile.
An IAM role is a way to grant permissions to an entity that you trust, such as an EC2 instance. An instance profile is a container for an IAM role that you can use to pass role information to an EC2 instance when the instance starts. By using an IAM role and an instance profile, the EC2 instances can automatically receive temporary security credentials from the AWS Security Token Service (STS) and use them to access the S3 buckets. This way, the company does not need to manage or rotate any long-term credentials, such as IAM users or access keys.
To use an IAM role and an instance profile, the company should create an IAM role that has the appropriate permissions for S3 buckets. The permissions should allow the EC2 instances to read from the source S3 bucket and write to the destination S3 bucket. The company should also create a trust policy for the IAM role that specifies that EC2 is allowed to assume the role. Then, the company should add the IAM role to an instance profile. An instance profile can have only one IAM role, so the company does not need to create multiple roles or profiles for this scenario.
Next, the company should update the launch template to include the IAM instance profile. A launch template is a way to save launch parameters for EC2 instances, such as the instance type, security group, user data, and IAM instance profile. By using a launch template, the company can ensure that all EC2 instances in the Auto Scaling group have consistent configuration and permissions. The company should specify the name or ARN of the IAM instance profile in the launch template. This way, when the Auto Scaling group launches new EC2 instances based on the launch template, they will automatically receive the IAM role and its permissions through the instance profile.
The other options are not correct because they do not meet the requirements or follow best practices. Creating an IAM user and generating a secret key and token is not a good option because it involves managing long-term credentials that need to be rotated regularly. Moreover, embedding credentials in user data is not secure because user data is visible to anyone who can describe the EC2 instance. Creating a trust anchor and profile is not a valid option because trust anchors are used for certificate-based authentication, not for IAM roles or instance profiles. Modifying user data to use a new secret key and token is also not a good option because it requires updating user data every time the credentials change, which is not scalable or efficient.

問題 #80
A DevOps engineer manages a company's Amazon Elastic Container Service (Amazon ECS) cluster. The cluster runs on several Amazon EC2 instances that are in an Auto Scaling group. The DevOps engineer must implement a solution that logs and reviews all stopped tasks for errors.
Which solution will meet these requirements?

A. Configure tasks to write log data in the embedded metric format. Store the logs in Amazon CloudWatch Logs. Monitor the ContainerInstanceCount metric for changes.
B. Create an Amazon EventBridge rule to capture task state changes. Send the event to Amazon CloudWatch Logs. Use CloudWatch Logs Insights to investigate stopped tasks.
C. Configure the EC2 instances to store logs in Amazon CloudWatch Logs. Create a CloudWatch Contributor Insights rule that uses the EC2 instance log data. Use the Contributor Insights rule to investigate stopped tasks.
D. Configure an EC2 Auto Scaling lifecycle hook for the EC2_INSTANCE_TERMINATING scale-in event. Write the SystemEventLog file to Amazon S3. Use Amazon Athena to query the log file for errors.

答案：B

解題說明：
Explanation
The best solution to log and review all stopped tasks for errors is to use Amazon EventBridge and Amazon CloudWatch Logs. Amazon EventBridge allows the DevOps engineer to create a rule that matches task state change events from Amazon ECS. The rule can then send the event data to Amazon CloudWatch Logs as the target. Amazon CloudWatch Logs can store and monitor the log data, and also provide CloudWatch Logs Insights, a feature that enables the DevOps engineer to interactively search and analyze the log data. Using CloudWatch Logs Insights, the DevOps engineer can filter and aggregate the log data based on various fields, such as cluster, task, container, and reason. This way, the DevOps engineer can easily identify and investigate the stopped tasks and their errors.
The other options are not as effective or efficient as the solution in option A. Option B is not suitable because the embedded metric format is designed for custom metrics, not for logging task state changes. Option C is not feasible because the EC2 instances do not store the task state change events in their logs. Option D is not relevant because the EC2_INSTANCE_TERMINATING lifecycle hook is triggered when an EC2 instance is terminated by the Auto Scaling group, not when a task is stopped by Amazon ECS.

問題 #81
A video-sharing company stores its videos in Amazon S3. The company has observed a sudden increase in video access requests, but the company does not know which videos are most popular. The company needs to identify the general access pattern for the video files. This pattern includes the number of users who access a certain file on a given day, as well as the numbA DevOps engineer manages a large commercial website that runs on Amazon EC2 The website uses Amazon Kinesis Data Streams to collect and process web togs The DevOps engineer manages the Kinesis consumer application, which also runs on Amazon EC2 Sudden increases of data cause the Kinesis consumer application to (all behind and the Kinesis data streams drop records before the records can be processed The DevOps engineer must implement a solution to improve stream handling Which solution meets these requirements with the MOST operational efficiency'' er of pull requests for certain files.
How can the company meet these requirements with the LEAST amount of effort?

A. Activate S3 server access logging. Import the access logs into an Amazon Aurora database. Use an Aurora SQL query to analyze the access patterns.
B. Record an Amazon CloudWatch Logs log message for every S3 object access event. Configure a CloudWatch Logs log stream to write the file access information, such as user, S3 bucket, and file key, to an Amazon Kinesis Data Analytics for SQL application. Perform a sliding window analysis.
C. Invoke an AWS Lambda function for every S3 object access event. Configure the Lambda function to write the file access information, such as user. S3 bucket, and file key, to an Amazon Aurora database.
Use an Aurora SQL query to analyze the access patterns.
D. Activate S3 server access logging. Use Amazon Athena to create an external table with the log files.
Use Athena to create a SQL query to analyze the access patterns.

答案：D

解題說明：
Activating S3 server access logging and using Amazon Athena to create an external table with the log files is the easiest and most cost-effective way to analyze access patterns. This option requires minimal setup and allows for quick analysis of theaccess patterns with SQL queries. Additionally, Amazon Athena scales automatically to match the query load, so there is no need for additional infrastructure provisioning or management.

問題 #82
A company gives its employees limited rights to AWS DevOps engineers have the ability to assume an administrator role. For tracking purposes, the security team wants to receive a near-real-time notification when the administrator role is assumed.
How should this be accomplished?

A. Create an Amazon EventBridge events rule using an AWS API call that uses an AWS CloudTrail event pattern to invoke an AWS Lambda function that publishes a message to an Amazon SNS topic if the administrator role is assumed.
B. Configure AWS Config to publish logs to an Amazon S3 bucket Use Amazon Athena to query the logs and send a notification to the security team when the administrator role is assumed
C. Create an Amazon EventBridge event rule using an AWS Management Console sign-in events event pattern that publishes a message to an Amazon SNS topic if the administrator role is assumed
D. Configure Amazon GuardDuty to monitor when the administrator role is assumed and send a notification to the security team

答案：A

解題說明：
Create an Amazon EventBridge Rule Using an AWS CloudTrail Event Pattern:
* AWS CloudTrail logs API calls made in your account, including actions performed by roles.
* Create an EventBridge rule that matches CloudTrail events where theAssumeRoleAPI call is made to assume the administrator role.
Invoke an AWS Lambda Function:
* Configure the EventBridge rule to trigger a Lambda function whenever the rule's conditions are met.
* The Lambda function will handle the logic to send a notification.
Publish a Message to an Amazon SNS Topic:
* The Lambda function will publish a message to an SNS topic to notify the security team.
* Subscribe the security team's email address to this SNS topic to receive real-time notifications.
Example EventBridge rule pattern:
{
"source": ["aws.cloudtrail"],
"detail-type": ["AWS API Call via CloudTrail"],
"detail": {
"eventSource": ["sts.amazonaws.com"],
"eventName": ["AssumeRole"],
"requestParameters": {
"roleArn": ["arn:aws:iam::<account-id>:role/AdministratorRole"]
}
}
}
Example Lambda function (Node.js) to publish to SNS:
const AWS = require('aws-sdk');
const sns = new AWS.SNS();
exports.handler = async (event) => {
const params = {
Message: `Administrator role assumed: ${JSON.stringify(event.detail)}`, TopicArn: 'arn:aws:sns:<region>:<account-id>:<sns-topic>'
};
await sns.publish(params).promise();
};

What are valid reasons for this failure? (Select TWO.).

A. An instance profile with proper permissions was not attached to the target EC2 instances.
B. The IAM user who triggered the application deployment does not have permission to interact with the CodeDeploy endpoint.
C. The networking configuration does not allow the EC2 instances to reach the internet via a NAT gateway or internet gateway and the CodeDeploy endpoint cannot be reached.
D. The appspec. yml file was not included in the application revision.
E. The target EC2 instances were not properly registered with the CodeDeploy endpoint.

答案：A,C
