A gaming application is deployed on four Amazon EC2 instances in a default VPC. The SysOps Administrator has noticed consistently high latency in responses as data is transferred among the four instances. There is no way for the Administrator to alter the application code.
The MOST effective way to reduce latency is to relaunch the EC2 instances in:

A sysops administrator is writing an AWS Cloud Formation template. The template will create a new Amazon S3 bucket and copy objects from an existing Amazon S3 bucket into the new bucket. The objects include data files, images, and scripts.
How should the CIoudFormation template be configured to perform this copy operation?
When the AWS Cloud infrastructure experiences an event that may impact an organization, which AWS service can be used to see which of the organization’s resources are affected?
A SysOps administrator recently launched an application consisting of web servers running on Amazon EC2 instances, an Amazon ElastiCache cluster communicating on port 6379, and an Amazon RDS tor PostgreSQL DB instance communicating on port 5432. The web servers are in the security group web-sg. the ElastiCache cluster is in the security group cache-sg. and the DB instance is in the security group database-sg.
The application fails on start, with the error message "Unable to connect to the database."
The rules in web-sg are as follows.
Which change should the SysOps administrator make to web-sg to correct the issue without compromising security?
