A SysOps administrator has successfully deployed a VPC with an AWS Cloud Formation template The SysOps administrator wants to deploy me same template across multiple accounts that are managed through AWS Organizations.
Which solution will meet this requirement with the LEAST operational overhead?

1. A. Assume the OrganizationAccountAcccssKolc IAM role from the management accoun
2. B. Deploy the template in each of the accounts
3. C. Create an AWS Lambda function to assume a role in each account Deploy the template by using the AWS CloudFormation CreateStack API call
4. D. Create an AWS Lambda function to query fc a list of accounts Deploy the template by using the AWS Cloudformation CreateStack API call.
5. E. Use AWS CloudFormation StackSets from the management account to deploy the template in each of the accounts

Correct Answer: D
AWS CloudFormation StackSets extends the capability of stacks by enabling you to create, update, or delete stacks across multiple accounts and AWS Regions

A company hosts a website on multiple Amazon EC2 instances that run in an Auto Scaling group. Users are reporting slow responses during peak times between 6 PM and 11 PM every weekend. A SysOps administrator must implement a solution to improve performance during these peak times.
What is the MOST operationally efficient solution that meets these requirements?

1. A. Create a scheduled Amazon EventBridge (Amazon CloudWatch Events) rule to invoke an AWS Lambda function to increase the desired capacity before peak times.
2. B. Configure a scheduled scaling action with a recurrence option to change the desired capacity before and after peak times.
3. C. Create a target tracking scaling policy to add more instances when memory utilization is above 70%.
4. D. Configure the cooldown period for the Auto Scaling group to modify desired capacity before and after peak times.

Correct Answer: B
"Scheduled scaling helps you to set up your own scaling schedule according to predictable load changes. For example, let's say that every week the traffic to your web application starts to increase on Wednesday, remains high on Thursday, and starts to decrease on Friday. You can configure a schedule for Amazon EC2 Auto Scaling to increase capacity on Wednesday and decrease capacity on Friday." https://docs.aws.amazon.com/autoscaling/ec2/userguide/schedule_time.html

A SysOps administrator is attempting to download patches from the internet into an instance in a private subnet. An internet gateway exists for the VPC, and a NAT gateway has been deployed on the public subnet; however, the instance has no internet connectivity. The resources deployed into the private subnet must be inaccessible directly from the public internet.

What should be added to the private subnet's route table in order to address this issue, given the information provided?

1. A. 0.0.0.0/0 IGW
2. B. 0.0.0.0/0 NAT
3. C. 10.0.1.0/24 IGW
4. D. 10.0.1.0/24 NAT

Correct Answer: B

A company has a simple web application that runs on a set of Amazon EC2 instances behind an Elastic Load Balancer in the eu-west-2 Region. Amazon Route 53 holds a DNS record for the application with a simple touting policy. Users from all over the world access the application through their web browsers.
The company needs to create additional copies of the application in the us-east-1 Region and in the ap-south-1 Region. The company must direct users to the Region that provides the fastest response times when the users load the application.
What should a SysOps administrator do to meet these requirements?

1. A. In each new Region, create a new Elastic Load Balancer and a new set of EC2 Instances to run a copy of the applicatio
2. B. Transition to a geolocation routing policy.
3. C. In each new Region, create a copy of the application on new EC2 instance
4. D. Add these new EC2 instances to the Elastic Load Balancer in eu-west-2. Transition to a latency routing policy.
5. E. In each new Region, create a copy of the application on new EC2 instance
6. F. Add these new EC2 instances to the Elastic Load Balancer in eu-west-2. Transition to a multivalue routing policy.
7. G. In each new Region, create a new Elastic Load Balancer and a new set of EC2 instances to run a copy of the applicatio
8. H. Transition to a latency routing policy.

Correct Answer: B

A company website contains a web tier and a database tier on AWS. The web tier consists of Amazon EC2 instances that run in an Auto Scaling group across two Availability Zones. The database tier runs on an Amazon ROS for MySQL Multi-AZ DB instance. The database subnet network ACLs are restricted to only the web subnets that need access to the database. The web subnets use the default network ACL with the default rules.
The company's operations team has added a third subnet to the Auto Scaling group configuration. After an Auto Scaling event occurs, some users report that they intermittently receive an error message. The error message states that the server cannot connect to the database. The operations team has confirmed that the route tables are correct and that the required ports are open on all security groups.
Which combination of actions should a SysOps administrator take so that the web servers can communicate with the DB instance? (Select TWO.)

1. A. On the default AC
2. B. create inbound Allow rules of type TCP with the ephemeral port range and the source as the database subnets.
3. C. On the default ACL, create outbound Allow rules of type MySQL/Aurora (3306). Specify the destinations as the database subnets.
4. D. On the network ACLs for the database subnets, create an inbound Allow rule of type MySQL/Aurora (3306). Specify the source as the third web subnet.
5. E. On the network ACLs for the database subnets, create an outbound Allow rule of type TCP with the ephemeral port range and the destination as the third web subnet.
6. F. On the network ACLs for the database subnets, create an outbound Allow rule of type MySQL/Aurora (3306). Specify the destination as the third web subnet.

Correct Answer: CD
