In regards to Amazon SQS how many times will you receive each message?
Correct Answer:D
Amazon SQS is engineered to provide "at least once" delivery of all messages in its queues. Although most of the time, each message will be delivered to your application exactly once, you should design your system so that processing a message more than once does not create any errors or inconsistencies.

An orgAMzation has created multiple components of a single application for compartmentalization. Currently all the components are hosted on a single EC2 instance. Due to security reasons the orgAMzation wants to implement two separate SSLs for the separate modules although it is already using VPC. How can the orgAMzation achieve this with a single instance?
Correct Answer:B
A Virtual Private Cloud (VPC) is a virtual network dedicated to the user’s AWS account. It enables the user to launch AWS resources into a virtual network that the user has defined. With VPC the user can specify multiple private IP addresses for his instances.
The number of network interfaces and private IP addresses that a user can specify for an instance depends on the instance type. With each network interface the orgAMzation can assign an EIP. This scenario helps when the user wants to host multiple websites on a single EC2 instance by using multiple SSL certificates on a single server and associating each certificate with a specific EIP address. It also helps in scenarios for operating network appliances, such as firewalls or load balancers that have multiple private IP addresses for each network interface.
