A user is sending a custom metric to CloudWatch. If the call to the CloudWatch APIs has different dimensions, but the same metric name, how will CloudWatch treat all the requests?
Explanation:
A dimension is a key-value pair used to uniquely identify a metric. CloudWatch treats each unique combination of dimensions as a separate metric. Thus, if the user is making 4 calls with the same metric name but a separate dimension, it will create 4 separate metrics.

Each subnet must reside entirely within one Availability Zone and cannot span across zones.

An organization is trying to setup a VPC with Auto Scaling. Which configuration steps below is not required to setup AWS VPC with Auto Scaling?
Explanation:
The Amazon Virtual Private Cloud (Amazon VPC) allows the user to define a virtual networking environment in a private, isolated section of the Amazon Web Services (AWS) cloud. The user has complete control over the virtual networking environment. Within this virtual private cloud, the user can launch AWS resources, such as an Auto Scaling group. Before creating the Auto Scaling group it is recommended that the user creates the Launch configuration. Since it is a VPC, it is recommended to select the parameter which does not allow assigning a public IP to the instances.
The user should also set the VPC security group with the Launch configuration and select the subnets where the instances will be launched in the AutoScaling group. The HA will be provided as the subnets may be a part of separate AZs.
