You are a student currently learning about the different AWS services. Your employer asks you to tell him a bit about Amazon's glacier service. Which of the following best describes the use cases for Glacier?
Correct Answer:
A
You need to create a management network using network interfaces for a virtual private cloud (VPC) network. Which of the following statements is incorrect pertaining to Best Practices for Configuring Network Interfaces.
Correct Answer:
D
Best Practices for Configuring Network Interfaces
You can attach a network interface to an instance when it\'s running (hot attach), when it\'s stopped (warm attach), or when the instance is being launched (cold attach). You can detach secondary (ethN) network interfaces when the instance is running or stopped. However, you can\'t detach the primary (eth0) interface.
You can attach a network interface in one subnet to an instance in another subnet in the same VPC, however, both the network interface and the instance must reside in the same Availability Zone. When launching an instance from the CLI or API, you can specify the network interfaces to attach to the instance for both the primary (eth0) and additional network interfaces. Launching an instance with multiple network interfaces automatically configures interfaces, private IP addresses, and route tables on the operating system of the instance. A warm or hot attach of an additional network interface may require you to manually bring up the second interface, configure the private IP address, and modify the route table accordingly. (Instances running Amazon Linux automatically recognize the warm or hot attach and configure themselves.) Attaching another network interface to
an instance is not a method to increase or double the network bandwidth to or from the dual-homed instance.

EBS (Elastic Block Store) can be best described as:
Correct Answer:
B
Amazon Elastic Block Store (Amazon EBS) provides block level (file system type) storage volumes for use with Amazon EC2 instances. Amazon EBS volumes are highly available and reliable storage volumes that can be attached to any running instance that is in the same Availability Zone. Amazon EBS volumes that are attached to an Amazon EC2 instance are exposed as storage volumes that
persist independently from the life of the instance. http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/AmazonEBS.html
