Amazon AWS Certified DevOps Engineer - Professional 認定 AWS-DevOps-Engineer-Professional 試験問題 (Q378-Q383):

質問 # 378
After conducting a disaster recovery exercise, an Enterprise Architect discovers that a large team of Database and Storage Administrators need more than seven hours of manual effort to make a flagship application's database functional in a different AWS Region. The Architect also discovers that the recovered database is often missing as much as two hours of data transactions.
Which solution provides improved RTO and RPO in a cross-region failover scenario?

A. Use Amazon SNS topics to receive published messages from Amazon RDS availability and backup events. Use AWS Lambda for three separate functions with calls to Amazon RDS to snapshot a database instance, create a cross-region snapshot copy, and restore an instance from a snapshot. Use a scheduled Amazon CloudWatch Events rule at a frequency matching the RPO to trigger the Lambda function to snapshot a database instance. Trigger the Lambda function to create a cross-region snapshot copy when the SNS topic for backup events receives a new message. Configure the Lambda function to restore an instance from a snapshot to trigger sending new messages published to the availability SNS topic.
B. Create a scheduled Amazon CloudWatch Events rule to make a call to Amazon RDS to create a snapshot from a database instance and specify a frequency to match the RPO. Create an AWS Step Functions task to call Amazon RDS to perform a cross-region snapshot copy into the failover region, and configure the state machine to execute the task when the RDS snapshot create state is complete.
Create an SNS topic subscribed to RDS availability events, and push these messages to an Amazon SQS queue located in the failover region. Configure an Auto Scaling group of worker nodes to poll the queue for new messages and make a call to Amazon RDS to restore a database from a snapshot after a checksum on the cross-region copied snapshot returns valid.
C. Deploy an Amazon RDS Multi-AZ instance backed by a multi-region Amazon EFS. Configure the RDS option group to enable multi-region availability for native automation of cross-region recovery and continuous data replication. Create an Amazon SNS topic subscribed to RDS-impacted events to send emails to the Database Administration team when significant query Latency is detected in a single Availability Zone.
D. Use Amazon RDS scheduled instance lifecycle events to create a snapshot and specify a frequency to match the RPO. Use Amazon RDS scheduled instance lifecycle event configuration to perform a cross-region snapshot copy into the failover region upon SnapshotCreateComplete events. Configure Amazon CloudWatch to alert when the CloudWatch RDS namespace CPUUtilization metric for the database instance falls to 0% and make a call to Amazon RDS to restore the database snapshot in the failover region.

質問 # 379
You currently have an Auto Scaling group with an Elastic Load Balancer and need to phase out all instances and replace with a new instance type. What are 2 ways in which this can be achieved.

A. Use Newest In stance to phase out all instances that use the previous configuration.
B. Use OldestLaunchConfiguration to phase out all instances that use the previous configuration. V
C. Attach an additional ELB to your Auto Scaling configuration and phase in newer instances while removing older instances.
D. Attach an additional Auto Scaling configuration behind the ELB and phase in newer instances while removing older instances.

正解：B、D

解説：
Explanation
When using the OldestLaunchConfiguration policy Auto Scaling terminates instances that have the oldest launch configuration. This policy is useful when you're updating a group and phasing out the instances from a previous configuration.
For more information on Autoscaling instance termination, please visit the below URL:
* http://docs.aws.amazon.com/autoscaling/latest/userguide/as-instance-termi nation.html Option D is an example of Blue Green Deployments.

A blue group carries the production load while a green group is staged and deployed with the new code. When if s time to deploy, you simply attach the green group to the existing load balancer to introduce traffic to the new environment. For HTTP/HTTP'S listeners, the load balancer favors the green Auto Scaling group because it uses a least outstanding requests routing algorithm As you scale up the green Auto Scaling group, you can take blue Auto Scaling group instances out of service by either terminating them or putting them in Standby state.
For more information on Blue Green Deployments, please refer to the below document link: from AWS

質問 # 380
You are using a configuration management system to manage your Amazon EC2 instances.
On your Amazon EC2 Instances, you want to store credentials for connecting to an Amazon RDS DB instance.
How should you securely store these credentials?

A. Store your credentials in your version control system, in plaintext.
Check out a copy of your credentials from the version control system on boot.
Use Amazon EBS encryption on the volume storing the Amazon RDS DB credentials.
B. Give the Amazon EC2 instances an IAM role that allows read access to a private Amazon S3 bucket.
Store a file with database credentials in the Amazon S3 bucket.
Have your configuration management system pull the file from the bucket when it is needed.
C. Assign an IAM role to your Amazon RDS instance, and use this IAM role to access the Amazon RDS DB from your Amazon EC2 instances.
D. Launch an Amazon EC2 instance and use the configuration management system to bootstrap the instance with the Amazon RDS DB credentials.
Create an AMI from this instance.
E. Store the Amazon RDS DB credentials in Amazon EC2 user data.
Import the credentials into the Instance on boot.

正解：B

質問 # 381
You are building a deployment system on AWS. You will deploy new code by bootstrapping instances in a private subnet in a VPC at runtime using UserData scripts pointing to an S3 zip file object, where your code is stored. An ELB in a public subnet has network interfaces and connectivity to the instances. Requests from users of the system are routed to the ELB via a Route53 A Record Alias. You do not use any VPC endpoints. Which is a risk of using this approach?

A. Route53 Alias records do not always update dynamically with ELB network changes after deploys.
B. Kernel changes to the base AMI may render the code inoperable.
C. The instances cannot be in a private subnet if the ELB is in a public one.
D. If the NAT routing for the private subnet fails, deployments fail.

正解：D

解説：
Since you are not using VPC endpoints, outbound requests for the code sitting in S3 are routed though the NAT for the VPC's private subnets. If this networking fails, runtime bootstrapping through code download will fail due to network unavailability and lack of access to the Internet, and thus Amazon S3.

質問 # 382
An application is running on Amazon EC2. It has an attached IAM role that is receiving an AccessDenied error while trying to access a SecureString parameter resource in the AWS Systems Manager Parameter Store.
The SecureString parameter is encrypted with a customer-managed Customer Master Key (CMK), What steps should the DevOps Engineer take to grant access to the role while granting least privilege? (Select three.)

A. Set kms:GenerateDataKey for the user on the AWS managed SSM KMS key.
B. Set kms:Decrypt for the customer-managed CMK resource in the role's IAM policy.
C. Set ssm:GetParamter for the parameter resource in the instance role's IAM policy.
D. Set kms:Decrypt for the instance role in the customer-managed CMK policy.
E. Set kms:Decrypt for the parameter resource in the customer-managed CMK policy.
F. Set ssm:DecryptParameter for the parameter resource in the instance role IAM policy.

正解：B、C、D
