AWS Certified Solutions Architect Associate (SAA-C03) - Master the Knowledge Areas

The video tutorial covers essential knowledge areas for the CSA C03 exam, focusing on designing secure, resilient, high-performing, and cost-optimized architectures. It includes an analysis of a sample question about configuring EC2 instances in a VPC, emphasizing the importance of using a NAT gateway for secure internet access. The tutorial concludes with a recap of key points and the importance of understanding these domains for the exam.

Which of the following is NOT one of the four key knowledge areas for the CSA C03 exam?

• Design cost-optimized architectures

• Design secure architectures

• Design resilient architectures

• Design scalable architectures

When considering AWS services, which of the following should always be a priority?

• Security and resiliency

• User interface design

• Customer feedback

• Marketing strategies

In a 3-tier web application, which tier is typically NOT included?

• Application server

• Database server

• Web server

• Network server

What is the primary purpose of using a NAT gateway in a VPC?

• To provide direct internet access to private subnets

• To allow EC2 instances in private subnets to access the internet

• To assign public IP addresses to EC2 instances

• To block all internet traffic

Why is it important to configure a custom route table with a route to the NAT gateway?

• To enable direct internet access for all subnets

• To block all incoming internet traffic

• To ensure internet traffic is routed through the NAT gateway

• To assign Elastic IP addresses to EC2 instances

Which configuration would incorrectly expose EC2 instances to the internet?

• Assigning an Elastic IP address to EC2 instances

• Using a NAT gateway in a public subnet

• Defining a custom route table with a route to the NAT gateway

• Associating private subnets with a route to the NAT gateway

What is the main reason for not placing a NAT instance in a private subnet?

• It would not be able to access the internet

• It would increase the cost

• It would not be able to access internal private subnets

• It would require additional security measures
