NEW QUESTION 1
A company runs its two-tier ecommerce website on AWS. The web tier consists of a load balancer that sends traffic to Amazon EC2 instances. The database tier uses an Amazon RDS DB instance. The EC2 instances and the RDS DB instance should not be exposed to the public internet. The EC2 instances require internet access to complete payment processing of orders through a third-party web service. The application must be highly available.
Which combination of configuration options will meet these requirements? (Choose two.)

• A. Use an Auto Scaling group to launch the EC2 instances in private subnet
• B. Deploy an RDS Multi-AZ DB instance in private subnets.
• C. Configure a VPC with two private subnets and two NAT gateways across two Availability Zones.Deploy an Application Load Balancer in the private subnets.
• D. Use an Auto Scaling group to launch the EC2 instances in public subnets across two Availability Zones.Deploy an RDS Multi-AZ DB instance in private subnets.
• E. Configure a VPC with one public subnet, one private subnet, and two NAT gateways across two Availability Zone
• F. Deploy an Application Load Balancer in the public subnet.
• G. Configure a VPC with two public subnets, two private subnets, and two NAT gateways across two Availability Zone
• H. Deploy an Application Load Balancer in the public subnets.

Answer: AE

Explanation:
Explanation
Before you begin: Decide which two Availability Zones you will use for your EC2 instances. Configure your
virtual private cloud (VPC) with at least one public subnet in each of these Availability Zones. These public subnets are used to configure the load balancer. You can launch your EC2 instances in other subnets of these Availability Zones instead.

NEW QUESTION 4
A development team needs to host a website that will be accessed by other teams. The website contents consist of HTML, CSS, client-side JavaScript, and images Which method is the MOST costeffective for hosting the website?

• A. Containerize the website and host it in AWS Fargate.
• B. Create an Amazon S3 bucket and host the website there
• C. Deploy a web server on an Amazon EC2 instance to host the website.
• D. Configure an Application Loa d Balancer with an AWS Lambda target that uses the Express js framework.

Answer: B

Explanation:
Explanation
In Static Websites, Web pages are returned by the server which are prebuilt.
They use simple languages such as HTML, CSS, or JavaScript.
There is no processing of content on the server (according to the user) in Static Websites. Web pages are returned by the server with no change therefore, static Websites are fast.
There is no interaction with databases.
Also, they are less costly as the host does not need to support server-side processing with different languages.
============
In Dynamic Websites, Web pages are returned by the server which are processed during runtime means they are not prebuilt web pages but they are built during runtime according to the user’s demand.
These use server-side scripting languages such as PHP, Node.js, ASP.NET and many more supported by the server.
So, they are slower than static websites but updates and interaction with databases are possible.

Which solution meets these requirements MOST cost-effectively?

• A. Stop the DB instance when tests are complete
