Which of the following are possible causes of this issue? (Select TWO.)
A company is about to launch a new product and is expecting a large increase in application traffic. The application is running on Amazon EC3 is an Auto scaling group and using an Amazon RDS multi-AZ instance. The static content is stored in Amazon S3. During the load test, the time to access the application increased significantly. A SysOps administrator wants to increase the scalability of the application without compromising the durability of the architecture.
How can this goal be achieved?
A recent AWS CloudFormation stack update has failed and returned the error update_rollback_failed. A Sysops administrator is tasked with returning the CloudFormation stack to its previous working state.
What must be done to accomplish this?
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?
An application is running on Amazon EC2 Instances behind an Application Load Balancer (ALB). An operations team wants to be notified in near-teal time when the ALB has issues connecting to backend EC2 instances.
Which solution will meet these requirements with the LEAST amount of effort?
A SysOps Administrator is tasked with deploying and managing a single CloudFormation templates across multiple AWS Accounts.
accomplish this?
A SysOpsAdministrator is managing a large organization with multiple accounts on the Business Support plan all linked to a single payer account. The Administrator wants to be notified automatically of AWS Personal Health Dashboard events.

Why did the alerts fail?
A company runs an Amazon RDS MySQL DB instance. Corporate policy requires that a daily backup of the database must be copied to a separate security account.
What is the MOST cost-effective way to meet this requirement?
An application runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The instances run in an Auto Scaling group across multiple Availability Zones. The Information Security team wants to track application requests by the originating IP and the EC2 instance that processes the request.
Which of the following tools or services provides this information?
A SysOps Administrator is deploying a legacy web application on AWS. The application has four Amazon EC2 instances behind Classic Load Balancer and stores data in an Amazon RDS instance. The legacy application has known vulnerabilities to SQL injection attacks, but the application code is no longer available to update.
What cost-effective configuration change should the Administrator make to migrate the risk of SQL injection attacks?
