AWS Certified Solutions Architect Associate (SAA-C02) Exam Prep Course - Using a Single EC2 Instance for Multi-Tier

The video tutorial covers setting up a single EC2 instance for a multi-tier architecture using AWS. It explains navigating the AWS Management Console, exploring the AWS Marketplace, and selecting appropriate Amazon Machine Images (AMIs). The tutorial details configuring EC2 instances, including advanced options like auto-scaling and IP management. It also covers adding storage and metadata, connecting to the instance using SSH, and managing the instance. Finally, it demonstrates cleaning up resources to ensure efficient use of AWS services.

What is the primary function of a single EC2 instance in a multi-tier architecture as discussed in the video?

• To offer separate functionalities for database, presentation, and business logic

• To provide a single point of failure

• To act as a backup server

• To host only the database layer

What is the AWS Marketplace primarily used for?

• Creating new AWS accounts

• Managing AWS billing

Which instance type is recommended for deploying the NEO 4J graph database?

• R5 Large

• T2 Micro

• M4 Large

• C5 Large

What is the purpose of auto-scaling in the context of EC2 instances?

• To automatically adjust the number of instances based on demand

• To increase the storage capacity

• To reduce the cost of the instance

What is the significance of a Virtual Private Cloud (VPC) in AWS?

• It is used for billing purposes

• It provides a public IP address

• It allows for the creation of isolated network environments

• It is a type of storage service

Why might you choose to use an Elastic IP address for an EC2 instance?

• To enhance the instance's security

• To increase the instance's storage capacity

• To ensure a consistent public IP address

What is the role of metadata tags in EC2 instances?

• To encrypt the instance's data

• To provide additional information and organization for instances

• To increase the instance's storage

• To reduce the instance's cost

What happens to the root volume of an EC2 instance when it is terminated?

• It is backed up to S3

• It is automatically deleted

• It is encrypted

• It is transferred to another instance

Why is it important to clean up resources after terminating an EC2 instance?

• To avoid unnecessary charges
