You have deployed an Elastic Beanstalk application in a new environment and want to save the current state of your environment in a document. You want to be able to restore your environment to the current state later or possibly create a new environment. You also want to make sure you have a restore point. How can you achieve this?

1. A. Use CloudFormation templates
2. B. Configuration Management Templates
3. C. Saved Configurations
4. D. Saved Templates

Correct Answer: C
You can save your environment\'s configuration as an object in Amazon S3 that can be applied to other environments during environment creation, or applied to a running environment. Saved configurations are YAML formatted templates that define an environment\'s platform configuration, tier, configuration option settings,
and tags.
For more information on Saved Configurations please refer to the below link:

During metric analysis, your team has determined that the company's website during peak hours is experiencing response times higher than anticipated. You currently rely on Auto Scaling to make sure that you are scaling your environment during peak windows. How can you improve your Auto Scaling policy to reduce this high response time? Choose 2 answers.

1. A. Push custom metrics to CloudWatch to monitor your CPU and network bandwidth from your servers, which will allow your Auto Scaling policy to have betterfine-grain insight.
2. B. IncreaseyourAutoScalinggroup\'snumberofmaxservers.
3. C. Create a script that runs and monitors your servers; when it detects an anomaly in load, it posts to an Amazon SNS topic that triggers Elastic Load Balancing to add more servers to the load balancer.
4. D. Push custom metrics to CloudWatch for your application that include more detailed information about your web application, such as how many requests it is handling and how many are waiting to be processed.

Correct Answer: BD
Option B makes sense because maybe the max servers is low hence the application cannot handle the peak load.
Option D helps in ensuring Autoscaling can scale the group on the right metrics.

Which of the following is false when it comes to using the Elastic Load balancer with Opsworks stacks?

1. A. Youcan attach only one load balancer to a layer.
2. B. A Classic Load Balancer can span across AWSOpsWorks Stacks layers.
3. C. Eachload balancer can handle only one layer.
4. D. Youneed to create the load balancer before hand and then attach it to the Opsworkstack.

Correct Answer: B
The AWS Documentation mentions the following
To use Clastic Load Balancing with a stack, you must first create one or more load balancers in the same region by using the Clastic Load Balancing console, CLI, or API. You should be aware of the following:
You can attach only one load balancer to a layer. Cach load balancer can handle only one layer.
AWS OpsWorks Stacks does not support Application Load Balancer. You can only use Classic Load Balancer with AWS OpsWorks Stacks. For more information on Clastic Load Balancer with Opswork,

You have been requested to use CloudFormation to maintain version control and achieve automation for the applications in your organization. How can you best use CloudFormation to keep everything agile and maintain multiple environments while keeping cost down?

1. A. Create separate templates based on functionality, create nested stacks with CloudFormation.
2. B. Use CloudFormation custom resources to handle dependencies between stacks
3. C. Create multiple templates in one CloudFormation stack.
4. D. Combine all resources into one template for version control and automation.

Correct Answer: A
As your infrastructure grows, common patterns can emerge in which you declare the same components in each of your templates. You can separate out these common components and create dedicated templates for them. That way, you can mix and match different templates but use nested stacks to create a single, unified stack. Nested stacks are stacks that create other stacks. To create nested stacks, use the AWS:: Cloud Form ation::Stackresource in your template to reference
other templates. For more information on Cloudformation best practises please refer to the below link:
