Amazon AWS Certified DevOps Engineer - Professional Sample Questions (Q386-Q391):

NEW QUESTION # 386
A company uses a complex system that consists of networking, IAM policies, and multiple three-tier applications. Requirements are still being defined for a new system, so the number of AWS components present in the final design is not known. The DevOps Engineer needs to begin defining AWS resources using AWS CloudFormation to automate and version-control the new infrastructure. What is the best practice for using CloudFormation to create new environments?

  • A. Create many separate templates for each logical part of the system, and provide the outputs from one to the next using an Amazon EC2 instance running SDK for granular control.
  • B. Create multiple separate templates for each logical part of the system, use cross-stack references in CloudFormation, and maintain several templates in version control.
  • C. Create a single template to encompass all resources that are required for the system so there is only one template to version-control.
  • D. Manually construct the networking layer using Amazon VPC and then define all other resources using CloudFormation.

Answer: B


NEW QUESTION # 387
A development team is building an ecommerce application and is using Amazon Simple Notification Service (Amazon SNS) to send order messages to multiple endpoints. One of the endpoints is an external HTTP endpoint that is not always available. The development team needs to receive a notification if an order message is not delivered to the HTTP endpoint.
What should a DevOps engineer do to meet these requirements?

  • A. Create an Amazon Simple Queue Service (Amazon SQS) queue. On the HTTP endpoint subscription of the SNS topic, configure a redrive policy that sends undelivered messages to the SQS queue. Create an Amazon CloudWatch alarm for the new SQS queue to notify the development team when messages are delivered to the queue.
  • B. Create an Amazon Simple Queue Service (Amazon SQS) queue. On the SNS topic, configure a redrive policy that sends undelivered messages to the SQS queue. Create an Amazon CloudWatch alarm for the new SQS queue to notify the development team when messages are delivered to the queue.
  • C. On the HTTP endpoint subscription of the SNS topic, configure an HTTPS delivery policy that will retry delivery until the order message is delivered successfully. Configure the backoffFunction parameter in the policy to notify the development team when a message cannot be delivered within the set constraints.
  • D. On the SNS topic, configure an HTTPS delivery policy that will retry delivery until the order message is delivered successfully. Configure the backoffFunction parameter in the policy to notify the development team when a message cannot be delivered within the set constraints.

Answer: D

NEW QUESTION # 388
By default in Opswork, how many application versions can you rollback up to?

  • A. 0
  • B. 1
  • C. 2
  • D. 3

Answer: B

Explanation:
Explanation
The AWS Documentation mentions the following Restores the previously deployed app version. For example, if you have deployed the app three times and then run Rollback, the server will serve the app from the second deployment. If you run Rollback again, the server will serve the app from the first deployment. By default, AWS OpsWorks Stacks stores the five most recent deployments, which allows you to roll back up to four versions. If you exceed the number of stored versions, the command fails and leaves the oldest version in place.

NEW QUESTION # 389
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 MYSQL DB instance. How should you securely store these credentials?

  • A. 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.
  • B. Assign an 1AM role to your Amazon EC2 instance, and use this 1AM role to access the Amazon RDS DB from your Amazon EC2 instances.
  • C. Give the Amazon EC2 instances an 1AM 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.
  • D. Store the Amazon RDS DB credentials in Amazon EC2 user data. Import the credentials into the Instance on boot.

Answer: B

Explanation:
Explanation
Creating and Using an 1AM Policy for 1AM Database Access
To allow an 1AM user or role to connect to your DB instance or DB cluster, you must create an 1AM policy.
After that you attach the policy to an 1AM user or role.
Note
To learn more about 1AM policies, see Authentication and Access Control for Amazon RDS.
The following example policy allows an 1AM user to connect to a DB instance using 1AM database authentication.

Important
Don't confuse the rds-db: prefix with other Amazon RDS action prefixes that begin with rds:. You use the rds-db: prefix and the rds-db:connect action only for 1AM database authentication. They aren't valid in any other context.
1AM Database Authentication for MySQL and Amazon Aurora
With Amazon RDS for MySQL or Aurora with MySQL compatibility, you can authenticate to your DB instance or DB cluster using AWS Identity and Access Management (IAMJ database authentication. With this authentication method, you don't need to use a password when you connect to a DB instance. Instead, you use an authentication token.
An authentication token is a unique string of characters that Amazon RDS generates on request.
Authentication tokens are generated using AWS Signature Version 4. Each token has a lifetime of 15 minutes.
You don't need to store user credentials in the database, because authentication is managed externally using
1AM. You can also still use standard database authentication.
IAM database authentication provides the following benefits:
* Network traffic to and from the database is encrypted using Secure Sockets Layer (SSL).
* You can use IAM to centrally manage access to your database resources, instead of managing access individually on each DB instance or DB cluster.
* For applications running on Amazon EC2, you can use EC2 instance profile credentials to access the database instead of a password, for greater security.
