Amazon Glacier is designed for____ & ______

infrequently accessed data & data archives.

This type of storage is a device like a RAM disk physically attached to your virtual server and characteristically it gets completely wiped every reboot

Your ec2 instance

This type of storage is suitable for temporary storage, but nothing that needs to survive something as simple as a reboot.

_____is a service where you buy devices more akin to a hard disk that can be attached to one (and only one -at the time of writing) EC2 instance

EBS (Elastic Block Store)

This storage option is best for storing your EC2 server images (Amazon Machine Images aka AMIs), static content e.g. for a web site, input or output data files (like you've use an SFTP site), or anything that you'd treat like a file.

You configured ELB to perform health checks on these EC2 instances. If an instance fails to pass health checks what can we assume the ELB will do?

The ELB stops sending traffic to the instance that failed its health check

These two items handle replacement of instances when they are configured. Then when an instance fails the health checks,presumably because it is down, it is these two items that will decide whether we now need to add another server to compensate

autoscaling group & launch configuration

A _________ tells AWS how to stand up a bootstrapped server that once up is ready to do work without any human intervention

launch configuration

This tells AWS where it can create servers : which launch configuration to use, the minimum and maximum allowed servers in the group, and how to scale up and down.

Auto Scaling Group

You are building a system to distribute confidential training videos to employees. Using CloudFront, what method could be used to serve content that is stored in S3, but not publically accessible from S3 directly?

Create an Origin Access Identity known as, OAI for CloudFront and grant access to the objects in your S3 bucket to that OAI.

You can restrict access to S3 content by creating a special Cloudfront user called:

origin access identiy (OAI) You restrict access to Amazon S3 content by creating an origin access identity, which is a special CloudFront user

An AWS account can have up to ____CloudFront origin access identities.

These two actions will occur when an EC2 instance in a VPC (Virtual Private Cloud) with an associated Elastic IP is stopped and started

All data on instance-store devices will be lost, a very abstract answer the underlying host for the instance is changed

True or false Elastic IPs are sticky until re-assigned

True Elastic Ips are sticky until the instance or volume they are associated with is deleted

EBS devices are ______of EC2 instances and by default _____them (unless configured otherwise). All data on Instance storage however will be lost and also on the root (/dev/sda1) partition of S3 backed servers

EBS devices are independent of EC2 instances and by default outlive them (unless configured otherwise). All data on Instance storage however will be lost and also on the root (/dev/sda1) partition of S3 backed servers
