A company's application on EC2 instances relies on a Single-AZ RDS for MySQL DB instance. The SysOps administrator needs to ensure failover to minimize downtime.
A SysOps administrator creates two VPCs, VPC1 and VPC2, in a company's AWS account The SysOps administrator deploys a Linux Amazon EC2 instance in VPC1 and deploys an Amazon RDS for MySQL DB instance in VPC2. The DB instance is deployed in a private subnet. An application that runs on the EC2 instance needs to connect to the database. What should the SysOps administrator do to give the EC2 instance the ability to connect to the database?
A company needs to monitor the disk utilization of Amazon Elastic Block Store (Amazon EBS) volumes The EBS volumes are attached to Amazon EC2 Linux Instances A SysOps administrator must set up an Amazon CloudWatch alarm that provides an alert when disk utilization increases to more than 80%. Which combination of steps must the SysOps administrator lake lo meet these requirements? (Select THREE.)
A company uses AWS CloudFormation to manage a stack of Amazon EC2 instances on AWS. A SysOps administrator needs to keep the instances and all of the instances' data, even if someone deletes the stack. Which solution will meet these requirements?
A SysOps administrator is optimizing the cost of a workload. The workload is running in multiple AWS Regions and is using AWS Lambda with Amazon EC2 On-Demand Instances for the compute. The overall usage is predictable. The amount of compute that is consumed in each Region varies, depending on the users' locations. Which approach should the SysOps administrator use to optimize this workload?
The SysOps administrator must dynamically reference the latest AMI ID from Systems Manager Parameter Store in CloudFormation templates for new AMI versions.
A company has an application that collects notifications from thousands of alarm systems. The notifications include alarm notifications and information notifications. The information notifications include the system arming processes, disarming processes, and sensor status. All notifications are kept as messages in an Amazon Simple Queue Service (Amazon SQS) queue. Amazon EC2 instances that are in an Auto Scaling group process the messages. A SysOps administrator needs to implement a solution that prioritizes alarm notifications over information notifications. Which solution will meet these requirements?
A team of developers is using several Amazon S3 buckets as centralized repositories. Users across the world upload large sets of files to these repositories. The development team's applications later process these files. A SysOps administrator sets up a new S3 bucket. DOC-EXAMPLE-BUCKET, to support a new workload. The new S3 bucket also receives regular uploads of large sets of files from users worldwide. When the new S3 bucket is put into production, the upload performance from certain geographic areas is lower than the upload performance that the existing S3 buckets provide. What should the SysOps administrator do to remediate this issue?
The SysOps administrator must modify the AWS Config rule that deletes noncompliant SSH inbound rules to update the rule to allow SSH from specific trusted IP addresses instead.
The company needs a solution to provide failover for a Single-AZ RDS for MySQL DB instance to minimize application downtime.

Question 344 - SOA-C02 discussion

Report
Export

A company uses AWS Organizations to host several applications across multiple AWS accounts. Several teams are responsible for building and maintaining the infrastructure of the applications across the AWS accounts.

A SysOps administrator must implement a solution to ensure that user accounts and permissions are centrally managed. The solution must be integrated with the company's existing on-premises Active Directory environment. The SysOps administrator already has enabled AWS 1AM Identity Center (AWS Single Sign-On) and has set up an AWS Direct Connect connection.

What is the MOST operationally efficient solution that meets these requirements?

A.
Create a Simple AD domain, and establish a forest trust relationship with the on-premises Active Directory domain. Set the Simple AD domain as the identity source for 1AM Identity Center. Create the required role-based permission sets. Assign each group of users to the AWS accounts that the group will manage.

Suggested answer: C

Explanation:

To manage user accounts and permissions across multiple AWS accounts and integrate with an on-premises Active Directory, using AD Connector is the most operationally efficient solution. AD Connector serves as a directory gateway with which you can redirect directory requests to your on-premises Microsoft Active Directory without storing any directory data in the cloud. This setup allows IAM Identity Center to use the existing corporate credentials, ensuring centralized management and seamless user access control. Option C perfectly meets these requirements by leveraging existing infrastructure with minimal changes. AWS documentation on AD Connector offers guidance AWS Directory Service AD Connector.
