The following are valid CLI commands for EC2 instances: ec2-accept-vpc-peering-connection
ec2-allocate-address
ec2-assign-private-ip-addresses ec2-associate-address

When using Amazon SQS how much data can you store in a message?
Correct Answer:
A
With Amazon SQS version 2008-01-01, the maximum message size for both SOAP and Query requests is 8KB.
If you need to send messages to the queue that are larger than 8 KB, AWS recommends that you split the information into separate messages. Alternatively, you could use Amazon S3 or Amazon Simp|eDB to hold the information and include the pointer to that information in the Amazon SQS message.
If you send a message that is larger than 8KB to the queue, you will receive a MessageTooLong error with HTTP code 400.

Which of the below mentioned options is not a best practice to securely manage the AWS access credentials?
Correct Answer:
D
It is a recommended approach to avoid using the access and secret access keys of the root account.
Thus, do not download or delete it. Instead make the IAM user as powerful as the root account and use its credentials. The user cannot generate their own access and secret access keys as they are always generated by AWS.

AWS Elastic Beanstalk stores your application files and optionally server log files in .
Correct Answer:
D
AWS Elastic Beanstalk stores your application files and optionally server log files in Amazon S3. If you are using the AWS Management Console, Git, the AWS Toolkit for Visual Studio, or AWS Toolkit for Eclipse, an Amazon S3 bucket will be created in your account for you and the files you upload will be automatically copied from your local client to Amazon S3. Optionally, you may configure Elastic Beanstalk to copy your server log files every hour to Amazon S3. You do this by editing the environment configuration settings.

A user is creating an EBS volume. He asks for your advice. Which advice mentioned below should you not give to the user for creating an EBS volume?
Correct Answer:

When a user creates an EBS volume, the user can attach it to a running instance. The user can attach multiple volumes to the same instance and stripe them together to increase the I/O. The user can take a snapshot from the existing volume but cannot create an AMI from the volume. However, the user can create an AMI from a snapshot.
