AWS Solutions Architect Associate (SAA-C02) Exam Prep Course - 2021 UPDATED! - Elastic IP Addresses

The video tutorial explains Elastic IPs (EIPs) in Amazon's VPC, highlighting their purpose, allocation, and management. EIPs are public IP addresses that can be moved between instances within the same region. They are permanently allocated to an account until released, incurring charges even if not in use. The tutorial covers the process of creating, associating, and releasing EIPs, emphasizing cost management and the importance of associating EIPs with network interfaces for public-facing connections.

What is an Elastic IP (EIP) in AWS?

• A private IP address for internal communication

• A public IP address that can be associated with instances in a VPC

• A static IP address that cannot be changed

• A temporary IP address for testing purposes

Why is it important to manage your Elastic IPs effectively?

• To avoid unnecessary charges for unused EIPs

• To ensure they are always associated with a network interface

• To prevent data loss

• To increase the speed of your network

How can Elastic IPs be moved between instances?

• They can only be moved within the same region

• They can be moved between instances in different VPCs

• They can be moved between any instances globally

• They cannot be moved once assigned

What is the first step in creating an Elastic IP in AWS?

• Going to the VPC management console

• Requesting an IP from your Internet Service Provider

• Associating it with an instance

• Releasing an existing IP

What should you do if you no longer need an Elastic IP?

• Keep it for future use

• Release it to avoid charges

• Transfer it to another account

• Convert it to a private IP

When allocating a new Elastic IP, what are the two options available?

• Opting for a regional or global IP

• Using Amazon's pool or a self-owned IP

• Choosing a private or public IP

• Selecting a static or dynamic IP

What is the consequence of not associating an Elastic IP with an instance?

• The IP will be automatically released

• The IP will become a private IP

• You will incur charges even if it's not in use

• The IP will be shared with other accounts
