A company has an application that is deployed 10 two AWS Regions in an active-passive configuration. The application runs on Amazon EC2 instances behind an Application Load Balancer (ALB) in each Region. The instances are in an Amazon EC2 Auto Scaling group in each Region. The application uses an Amazon Route 53 hosted zone (or DNS. A SysOps administrator needs to configure automatic failover to the secondary Region.
What should the SysOps administrator do to meet these requirements?
You need to update an existing AWS CloudFormation stack. If needed, a copy to the CloudFormation template is available in an Amazon SB bucket named cloudformation-bucket
1. Use the us-east-2 Region for all resources.
2. Unless specified below, use the default configuration settings.
3. update the Amazon EQ instance named Devinstance by making the following changes to the stack named 1700182:
a) Change the EC2 instance type to us-east-t2.nano.
b) Allow SSH to connect to the EC2 instance from the IP address range
192.168.100.0/30.
c) Replace the instance profile IAM role with IamRoleB.
4. Deploy the changes by updating the stack using the CFServiceR01e role.
5. Edit the stack options to prevent accidental deletion.
6. Using the output from the stack, enter the value of the Prodlnstanceld in the text box below:
A company has a memory-intensive application that runs on a fleet of Amazon EC2 instances behind an Elastic Load Balancer (ELB). The instances run in an Auto Scaling group. A Sysops administrator must ensure that the application can scale based on the number of users that connect to the application.
Which solution will meet these requirements?
This solution will allow the application to scale based on the number of users that connect to the application. The other solutions (creating a scaling policy that uses the ActiveConnectionCount Amazon CloudWatch metric generated from the ELB, creating a scaling policy that uses the mem used Amazon CloudWatch metric generated from the ELB, or creating a scheduled scaling policy to increase the number of EC2 instances in the Auto Scaling group to support additional connections) will not meet the requirements, as they do not allow the application to scale based on the number of users that connect to the application.

A webpage is stored in an Amazon S3 bucket behind an Application Load Balancer (ALB). Configure the SS bucket to serve a static error page in the event of a failure at the primary site.
1. Use the us-east-2 Region for all resources.
2. Unless specified below, use the default configuration settings.
3. There is an existing hosted zone named lab-
751906329398-26023898.com that contains an A record with a simple routing policy that routes traffic to an existing ALB.
4. Configure the existing S3 bucket named lab-751906329398-26023898.com as a static hosted website using the object named index.html as the index document
5. For the index-html object, configure the S3 ACL to allow for public read access. Ensure public access to the S3 bucketjs allowed.
6. In Amazon Route 53, change the A record for domain lab-751906329398-26023898.com to a primary record for a failover routing policy. Configure the record so that it evaluates the health of the ALB to determine failover.
7. Create a new secondary failover alias record for the domain lab-751906329398-26023898.com that routes traffic to the existing 53 bucket.
