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 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?
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?
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?
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 SysOps administrator needs to prevent launching EC2 instances without a specific tag in the application OU.
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?

A SysOps administrator needs to implement a backup strategy for Amazon EC2 resources and Amazon RDS resources. The backup strategy must meet the following retention requirements:

* Daily backups: must be kept for 6 days

* Weekly backups: must be kept for 4 weeks:

* Monthly backups: must be kept for 11 months

* Yearly backups: must be kept for 7 years

Which backup strategy will meet these requirements with the LEAST administrative effort?

A.
Use Amazon Data Lifecycle Manager to create an Amazon Elastic Block Store (Amazon EBS) snapshot policy. Create tags on each resource that needs to be backed up. Create multiple schedules according to the requirements within the policy. Set the appropriate frequency and retention period.

Suggested answer: B

Explanation:

AWS Backup provides a centralized way to manage backups across AWS services. Here's how to implement the required backup strategy with minimal administrative effort:

Create Backup Plans: Set up different backup plans in AWS Backup, each configured for a specific backup frequency---daily, weekly, monthly, and yearly.

Set Retention Periods: For each backup plan, configure the retention settings to align with the required retention durations: 6 days, 4 weeks, 11 months, and 7 years respectively.

Tag Resources: Apply tags to each EC2 and RDS resource that needs to be backed up. This allows for the automated inclusion of these resources in the respective backup plans based on their tags.

Assign Resources to Backup Plans: Use the tags to define which resources are included in each backup plan, ensuring that all necessary resources are backed up according to the defined schedules and retention policies.
