Explanation:
The RDS instances unlike the AWS EBS backed instances cannot be stopped or paused. The user
needs
to take the final snapshot, terminate the instance and launch a new instance in the future from that
snapshot.

Answer: C

Explanation:
Every Amazon SQS queue has a configurable visibility timeout. For the designated amount of time
after a
message is read from a queue, it will not be visible to any other reader. As long as the amount of time
that
it takes to process the message is less than the visibility timeout, every message will be processed
and
deleted. In the event that the component processing the message fails or becomes unavailable, the
message will again become visible to any component reading the queue once the visibility timeout
ends.
This allows you to have many components all reading messages from the same queue, with each
working
to process different messages.

Explanation:
AutoScaling attempts to distribute instances evenly between the Availability Zones that are enabled
for
the user's AutoScaling group. Auto Scaling does this by attempting to launch new instances in the
Availability Zone with the fewest instances.

and script custom resources

Answer: A

Explanation:
These services are designed to complement each other. AWS Elastic Beanstalk provides an
environment
to easily develop and run applications in the cloud. It is integrated with developer tools and provides
a
one-stop experience for you to manage the lifecycle of your applications. AWS CloudFormation is a
convenient deployment mechanism for a broad range of AWS resources. It supports the
infrastructure
needs of many different types of applications such as existing enterprise applications, legacy
applications,
applications built using a variety of AWS resources and container-based solutions (including those
built
using AWS Elastic Beanstalk).
AWS CloudFormation introduces two new concepts: The template, a JSON-format, text-based file
that
describes all the AWS resources you need to deploy to run your application and the stack, the set of
AWS
resources that are created and managed as a single unit when AWS CloudFormation instantiates a
template.
