As you develop your web pages, you should test them frequently. The best way to test a web page is to preview it in a browser window to make sure it appears the way you expect it to. You should also check to see that the links work properly, that there are no typographical or grammatical errors, and that you have included all of the necessary information for the page. Dreamweaver has a preview feature that allows you to see what a page would look like if it were viewed on a mobile hand-held device, such as a phone or tablet. This is a feature called the Multiscreen Preview. The Multiscreen button is located on the Document toolbar. This button allows you to see the page in three different sizes in the same window, or you can choose one size to preview in the whole Document window. You can also use the Mobile size , the Tablet size , or the Desktop size buttons on the Status bar to simulate page size. You decide to view The Striped Umbrella home page in Dreamweaver to check its appearance in a simulated window size, preview it using your default browser, make adjustments to the page, then preview the changes in the browser.

Your company has decided to set up a new AWS account for test and dev purposes. They already use AWS for production, but would like a new account dedicated for test and dev so as to not accidentally break the production environment. You launch an exact replica of your production environment using a CloudFormation template that your company uses in production. However CloudFormation fails. You use the exact same CloudFormation template in production, so the failure is something to do with your new AWS account. The CloudFormation template is trying to launch 60 new EC2 instances in a single AZ. After some research you discover that the problem is;
A. For all new AWS accounts there is a soft limit of 20 EC2 instances per region. You should submit the limit increase form and retry the template after your limit has been increased. B. For all new AWS accounts there is a soft limit of 20 EC2 instances per availability zone. You should submit the limit increase form and retry the template after your limit has been increased. C. You cannot launch more than 20 instances in your default VPC, instead reconfigure the CloudFormation template to provision the instances in a custom VPC. D. Your CloudFormation template is configured to use the parent account and not the new account. Change the account number in the CloudFormation template and relaunch the template.
