NEW QUESTION # 304
A company uses Amazon EC2 instances to host applications for its customers. Recently, the company's support team has received EC2 scheduled maintenance notifications regarding its EC2 instances.
The support team wants to automatically perform a restart of any EC2 instances with a scheduled maintenance event before the scheduled date.
Which solution will meet these requirements while requiring the MINIMUM amount of development effort?

  • A. Create an Amazon EventBridge (Amazon CloudWatch Events) rule that matches scheduledChange events for Amazon EC2 from AWS Health. Create an AWS Lambda function that uses the EC2 API to list all EC2 instances with scheduled events and then uses the RebootInstances EC2 API operation to restart the affected EC2 instances. Configure the EventBridge (CloudWatch Events) rule to invoke the Lambda function.
  • B. Create an Amazon EventBridge (Amazon CloudWatch Events) rule that matches scheduledChange events for Amazon EC2 from AWS Health. Configure the rule to run the AWS- RestartEC2Instance AWS Systems Manager Automation runbook.
  • C. Create an AWS Systems Manager maintenance window with a Systems Manager Automation tast that uses the RebootInstnaces EC2 API operation to restart the affected EC2 instances. Attach the EC2 instances to the maintenance window. Configure AWS Health to invoke the maintenance window whenever a scheduledChange event for Amazon EC2 is generated.
  • D. Create an Amazon CloudWatch alarm for the StatusCheckFailed metric of each EC2 instance.
    Configure the CloudWatch alarm to recover any affected EC2 instance.

NEW QUESTION # 305
A DevOps team needs to query information in application logs that are generated by an application running multiple Amazon EC2 instances deployed with AWS Elastic Beanstalk. Instance log streaming to Amazon CloudWatch Logs was enabled on Elastic Beanstalk. Which approach would be the MOST cost-efficient?

  • A. Use a CloudWatch Logs subscription to send the log data to an Amazon Kinesis Data Firehouse stream that has an Amazon S3 bucket destination. Use Amazon Athena to query the log data from the bucket.
  • B. Use a CloudWatch Logs subscription to trigger an AWS Lambda function to send the log data to an Amazon Kinesis Data Firehouse stream that has an Amazon S3 bucket destination. Use Amazon Athena to query the log data from the bucket.
  • C. Use a CloudWatch Logs subscription to send the log data to an Amazon Kinesis Data Firehouse stream that has an Amazon S3 bucket destination. Use a new Amazon Redshift cluster and Amazon Redshift Spectrum to query the log data from the bucket.
  • D. Use a CloudWatch Logs subscription to trigger an AWS Lambda function to send the log data to an Amazon Kinesis Data Firehouse stream that has an Amazon S3 bucket destination. Use a new Amazon Redshift cluster and Amazon Redshift Spectrum to query the log data from the bucket.

Answer: A

NEW QUESTION # 306
You work for an accounting firm and need to store important financial data for clients. Initial frequent access
to data is required, but after a period of 2 months, the data can be archived and brought back only in the case
of an audit. What is the most cost-effective way to do this?

  • A. Storeall data in a private S3 bucket
  • B. Uselifecycle management to move data from S3 to Glacier
  • C. Storeall data in a Glacier
  • D. Uselifecycle management to store all data in Glacier

Answer: B

Explanation:
Explanation
The AWS Documentation mentions the following
Lifecycle configuration enables you to specify the lifecycle management of objects in a bucket. The
configuration is a set of one or more rules, where each rule
defines an action for Amazon S3 to apply to a group of objects. These actions can be classified as follows:
Transition actions - In which you define when objects transition to another storage class. For example, you
may choose to transition objects to the STANDARDJ A (IA, for infrequent access) storage class 30 days after
creation, or archive objects to the GLACIER storage class one year after creation.
Cxpiration actions - In which you specify when the objects expire. Then Amazon S3 deletes the expired
objects on your behalf. For more information on S3 Lifecycle policies, please visit the below URL:

NEW QUESTION # 307
A media customer has several thousand amazon EC2 instances in an AWS account. The customer is using a Slack channel for team communications and important updates. A DevOps Engineer was told to send all AWS-scheduled maintenance notifications to the company Slack channel.
Which method should the Engineer use to implement this process in the LEAST amount of steps?

  • A. Integrate AWS Support with AWS CloudTrail. Based on the CloudTrail lookup event created, the event can invoke an AWS Lambda function to pass EC2 maintenance notifications to the Slack channel.
  • B. Integrate AWS Trusted Advisor with AWS Config. Based on the AWS Config rules created, the AWS Config event can invoke an AWS Lambda function to send notifications to the Slack channel.
  • C. Integrate AWS Personal Health Dashboard with Amazon CloudWatch Events. Based on the CloudWatch Events created, the event can invoke an AWS Lambda function to send notifications to the Slack channel.
  • D. Integrate EC2 events with Amazon CloudWatch monitoring. Based on the CloudWatch Alarm created, the alarm can invoke an AWS Lambda function to send EC2 maintenance notifications to the Slack channel.

Answer: D


NEW QUESTION # 308
If Erin has three clusters of server types that are all managed by Ansible and she needs to provision each cluster so that they are configured with their appropriate NTP server addresses.
What is the best method Erin should use in Ansible for managing this?

  • A. Create a playbook for each different region and store the NTP address in a variable in the play in the event the NTP server changes.
  • B. Break down the hosts by region in the Ansible inventory file and assign an inventory group variable the NTP address value for the respective region. The playbook can contain just the single play referencing the NTP variable from the inventory.
  • C. Write a task that scans the network in the target hosts' region for the NTP server, register the resulting address so that the next task can write the NTP configuration.
  • D. Create three plays, each one has the hosts for their respective regions and set the NTP server address in each task.

Answer: B

Explanation:
While all four answers provided are correct, only B is the best choice. Ansible offers the ability to assign variables to groups of hosts in the inventory file. When the playbook is ran it will use the variables assigned to the group, even all the groups are specified in a single playbook run. The respective variables will be available to the play. This is easiest method to run, maintain and write.
