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?

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.

An AWS Cloud Formation template creates an Amazon RDS instance This template is used to build up development environments as needed and then delete the stack when the environment is no longer required. The RDS-persisted data must be retained for further use. even after the Cloud Format ton stack is deleted

How can this be achieved in a reliable and efficient way?

A.

D.
Create a new CloudFormallon template to perform backups of the RDS instance, and run this template before deleting the stack.
Answers
D.
Create a new CloudFormallon template to perform backups of the RDS instance, and run this template before deleting the stack.
Suggested answer: C

Explanation:

Snapshot Deletion Policy:

The Snapshot Deletion Policy ensures that a snapshot is created when an RDS instance is deleted as part of a CloudFormation stack deletion.

Steps:

Update your CloudFormation template to include the DeletionPolicy attribute for the RDS instance resource.

Example template snippet:

Resources:

MyDBInstance:

Type: AWS::RDS::DBInstance

Properties:

# DB instance properties

DeletionPolicy: Snapshot

This configuration retains a snapshot of the RDS instance data when the stack is deleted.

Reference: AWS CloudFormation DeletionPolicy
