질문 # 205
A company has a web application with a database tier that consists of an Amazon EC2 instance that runs MySQL. A SysOps administrator needs to minimize potential data loss and the time that is required to recover in the event of a database failure.
What is the MOST operationally efficient solution that meets these requirements?

A. Use Amazon Data Lifecycle Manager (Amazon DLM) to take a snapshot of the Amazon Elastic Block Store (Amazon EBS) volume every hour. In the event of an EC2 instance failure, restore the EBS volume from a snapshot.
B. Create an Amazon RDS for MySQL Single-AZ DB instance with a read replica. Use a MySQL native backup that is stored in Amazon S3 to restore the data to the new database. Update the connection string in the web application.
C. Create an Amazon CloudWatch alarm for the StatusCheckFailed_System metric to invoke an AWS Lambda function that stops and starts the EC2 instance.
D. Create an Amazon RDS for MySQL Multi-AZ DB instance. Use a MySQL native backup that is stored in Amazon S3 to restore the data to the new database. Update the connection string in the web application.

정답：D

설명：
Step-by-Step Explanation:
* Understand the Problem:
* Minimize potential data loss and recovery time for a MySQL database running on an Amazon EC2 instance.
* Analyze the Requirements:
* Reduce the risk of data loss.
* Ensure quick recovery in the event of a database failure.
* Aim for operational efficiency.
* Evaluate the Options:
* Option A: Create a CloudWatch alarm to invoke a Lambda function that stops and starts the EC2 instance.
* This addresses system failures but does not help with minimizing data loss or ensuring database redundancy.
* Option B: Create an Amazon RDS for MySQL Multi-AZ DB instance and use a MySQL native backup stored in Amazon S3.
* RDS Multi-AZ deployments provide high availability and durability by automatically replicating data to a standby instance in a different Availability Zone.
* Using a MySQL native backup stored in Amazon S3 ensures data can be restored efficiently.
* Option C: Create an RDS for MySQL Single-AZ DB instance with a read replica.
* This provides read scalability but does not ensure high availability or failover capabilities.
* Option D: Use Amazon DLM to take hourly snapshots of the EBS volume.
* This helps with backups but does not provide immediate failover capabilities or minimize downtime effectively.
* Select the Best Solution:
* Option B: Using Amazon RDS for MySQL Multi-AZ ensures high availability and automated backups, significantly minimizing data loss and recovery time.

* Amazon RDS Multi-AZ Deployments
* Backing Up and Restoring an Amazon RDS DB Instance
Using Amazon RDS for MySQL Multi-AZ provides a highly available and durable solution with automated backups, ensuring minimal data loss and quick recovery.

질문 # 206
A company hosts a database on an Amazon RDS Multi-AZ DB instance. The database is not encrypted. The company's new security policy requires all AWS resources to be encrypted at rest and in transit.
What should a SysOps administrator do to encrypt the database?

A. Encrypt the standby replica in a secondary Availability Zone. Promote the standby replica to the primary DB instance.
B. Take a snapshot of the DB instance. Encrypt the snapshot. Restore the snapshot to the same DB instance.
C. Take a snapshot of the DB instance. Copy and encrypt the snapshot. Create a new DB instance by restoring the encrypted copy.
D. Configure encryption on the existing DB instance.

정답：C

설명：
To encrypt an existing Amazon RDS DB instance that is not encrypted, you cannot directly enable encryption.
Instead, you need to follow these steps:
* Take a Snapshot:
* Open the Amazon RDS console at Amazon RDS Console.
* Select the DB instance and take a snapshot.
* Copy and Encrypt the Snapshot:
* After the snapshot is created, select the snapshot and choose Copy Snapshot.
* In the copy snapshot dialog, enable encryption and choose a KMS key.
* Restore the Encrypted Snapshot:
* Once the encrypted snapshot is created, select it and choose Restore Snapshot.
* Provide the necessary details to create a new DB instance from the encrypted snapshot.
This process ensures that the new DB instance is encrypted at rest.

* Copying an Amazon RDS Snapshot

질문 # 207
A SysOps administrator creates an AWS CloudFormation template to define an application stack that can be deployed in multiple AWS Regions.
The SysOps administrator also creates an Amazon CloudWatch dashboard by using the AWS Management Console. Each deployment of the application requires its own CloudWatch dashboard.
How can the SysOps administrator automate the creation of the CloudWatch dashboard each time the application is deployed?

A. Update the CloudFormation template to define an resource. Use the intrinsic Ref function to reference the ID of the existing CloudWatch dashboard.
B. Export the existing CloudWatch dashboard as JSON. Update the CloudFormation template to define an AWS::CloudWatch::Dashboard resource. Include the exported JSON in the resource's DashboardBody property.
C. Create a script by using the AWS CLI to run the aws cloudformation put-dashboard command with the name of the dashboard. Run the command each time a new CloudFormation stack is created.

정답：C

설명：
D. Update the CloudFormation template to define an AWS::CloudWatch::Dashboard resource. Specify the name of the existing dashboard in the DashboardName property.

질문 # 208
A company monitors its account activity using AWS CloudTrail. and is concerned that some log files are being tampered with after the logs have been delivered to the account's Amazon S3 bucket.
Moving forward, how can the SysOps administrator confirm that the log files have not been modified after being delivered to the S3 bucket?

A. Replicate the S3 log bucket across regions, and encrypt log files with S3 managed keys.
B. Enable log file integrity validation and use digest files to verify the hash value of the log file.
C. Enable S3 server access logging to track requests made to the log bucket for security audits.
D. Stream the CloudTrail logs to Amazon CloudWatch Logs to store logs at a secondary location.

정답：B

설명：
When you enable log file integrity validation, CloudTrail creates a hash for every log file that it delivers. Every hour, CloudTrail also creates and delivers a file that references the log files for the last hour and contains a hash of each. This file is called a digest file. CloudTrail signs each digest file using the private key of a public and private key pair. After delivery, you can use the public key to validate the digest file. CloudTrail uses different key pairs for each AWS region

질문 # 209
A company runs a multi-tier web application with two Amazon EC2 instances in one Availability Zone in the us-east-1 Region. A SysOps administrator must migrate one of the EC2 instances to a new Availability Zone Which solution will accomplish this?

A. Stop the EC2 instance, modify the Availability Zone, and start the instance.
B. Create an Amazon Machine Image (AMI) from the EC2 instance and launch it in a different Availability Zone. Terminate the original instance
C. Copy the EC2 instance to a different Availability Zone. Terminate the original instance
D. Move the EC2 instance to a different Availability Zone using the AWS CLI.

정답：B

설명：
* Amazon EC2 and Availability Zones:
* EC2 instances are tied to a specific Availability Zone within a region. Moving an instance directly is not possible.
* Creating an Amazon Machine Image (AMI) allows the instance to be recreated in another Availability Zone.
* Steps to Migrate an EC2 Instance to a New Availability Zone:
* Create an AMI:
* Open the EC2 Console.
* Select the EC2 instance you want to migrate.
* Choose Actions > Image and templates > Create Image.
* Configure the AMI creation settings and create the image.
* Launch a New Instance:
* Navigate to the AMI section in the EC2 Console.
* Select the newly created AMI.
* Click Launch Instance from Image.
* Specify the new Availability Zone during the instance configuration.
* Terminate the Original Instance:
* After validating that the new instance is functioning correctly, terminate the original instance to avoid additional costs.
* Why Other Options Are Incorrect:
* A: Directly copying an instance to another AZ is not supported.
* C: There is no AWS CLI command to move an EC2 instance between AZs.
* D: Stopping and modifying the AZ of an existing instance is not possible.
References:
* Amazon EC2 Documentation
* Creating an AMI
