A SysOps administrator is setting up an automated process to recover an Amazon EC2 instance in the event of an underlying hardware failure. The recovered instance must have the same private IP address and the same Elastic IP address that the original instance had. The SysOps team must receive an email notification when the recovery process is initiated.
Which solution will meet these requirements?

Correct Answer:A

A new website will run on Amazon EC2 instances behind an Application Load Balancer. Amazon Route 53 will be used to manage DNS records.
What type of record should be set in Route 53 to point the website’s apex domain name (for example, “company.com”) to the Application Load Balancer?

Correct Answer:D

Your new application is hosted in an Auto Scaling group of EC2 instances. To improve the monitoring
process, you have to configure it to keep the average aggregate CPU utilization of your Auto Scaling
group at 50 percent. This should be done by specifying the scaling metrics and threshold values for
the CloudWatch alarms that trigger the scaling process.
Which of the following scaling policy type you should use?

Correct Answer:B
Target tracking scaling is the correct answer. With target tracking scaling policies, you select a scaling
metric and set a target value. Amazon EC2 Auto Scaling creates and manages the CloudWatch alarms
that trigger the scaling policy and calculates the scaling adjustment based on the metric and the
target value. The scaling policy adds or removes capacity as required to keep the metric at, or close
to, the specified target value. In addition to keeping the metric close to the target value, a target
tracking scaling policy also adjusts to changes in the metric due to a changing load pattern.
For example, you can use target tracking scaling to:
Configure a target tracking scaling policy to keep the average aggregate CPU utilization of your
Auto Scaling group at 50 percent.
Configure a target tracking scaling policy to keep the request count per target of your Application
Load Balancer target group at 1000 for your Auto Scaling group.
Step scaling policies and simple scaling policies are incorrect. Step scaling policies and simple scaling
policies are two of the dynamic scaling options available for you to use. Both require you to create
CloudWatch alarms for the scaling policies. Both require you to specify the high and low thresholds for
the alarms. Both require you to define whether to add or remove instances, and how many, or set the
group to an exact size.
The main difference between the policy types is the step adjustments that you get with step scaling
policies. When step adjustments are applied, and they increase or decrease the current capacity of
your Auto Scaling group, the adjustments vary based on the size of the alarm breach.
In most cases, step scaling policies are a better choice than simple scaling policies, even if you have
only a single scaling adjustment.
Threshold scaling is inorrect as it is a fictitious scaling policy type.

A SysOps Administrator is troubleshooting Amazon EC2 connectivity issues to the internet. The EC2 instance is in a private subnet. Below is the route table that is applied to the subnet of the EC2 instance.
Destination – 10.2.0.0/16
Target – local
Status – Active
Propagated – No
Destination – 0.0.0.0/0
Target – nat-xxxxxxx
Status – Blackhole
Propagated – No
What has caused the connectivity issue?

Correct Answer:A

An organization is running multiple applications for their customers. Each application is deployed by running a base AWS CloudFormation template that configures a new VPC. All applications are run in the same AWS account and AWS Region. A SysOps administrator has noticed that when trying to deploy the same AWS CloudFormation stack, it fails to deploy.
What is likely to be the problem?

Correct Answer:D
