Correct Answer : Get Lastest Questions and Answer :
Instance-store backed images use "ephemeral" storage (temporary). The storage is only available during the life of an instance. Rebooting an instance will allow ephemeral data stay persistent. However, stopping and starting an instance will remove all ephemeral storage.

Correct Answer : Get Lastest Questions and Answer :
ElastiCache allows session information to be stored in a central location. This creates mobility between traffic on instances. Stickiness on the elastic load balancer will cause the ELB to "remember" where the session was created and route traffic based off that data. In the event of high amounts of traffic or even an outage this can cause serious issues.





Question :

AMIs can be shared to individual AWS accounts


1. True
2. False


Correct Answer : Get Lastest Questions and Answer :

Explanation: A shared AMI is an AMI that a developer created and made available for other developers to use. One of the easiest ways to get started with Amazon EC2 is to use a shared AMI that has the components you need and then add custom content.

You use a shared AMI at your own risk. Amazon can't vouch for the integrity or security of AMIs shared by other Amazon EC2 users. Therefore, you should treat shared AMIs as you would any foreign code that you might consider deploying in your own data center and perform the appropriate due diligence.

We recommend that you get an AMI from a trusted source. If you have questions or observations about a shared AMI, use the AWS forums.

Amazon's public images have an aliased owner, which appears as amazon in the account field. This enables you to find AMIs from Amazon easily. Other users can't alias their AMIs.
