All SOA-C02 Test Inside Amazon Web Services Questions

If the MFA device for the root user is lost, you can regain access to the AWS account by using email and phone verification. AWS Support provides a process to recover root account access.

Recover Root Account Access:

Go to the AWS sign-in page and choose Root user.

Enter the root user email address.

On the MFA prompt page, choose Troubleshoot MFA.

Follow the prompts for email and phone verification to verify your identity.

Set Up a New MFA Device:

Once you regain access, navigate to the IAM console at IAM Console.

Go to the Users section and select the root user.

Set up a new MFA device.

Change the Root User Password:

It is recommended to change the root user password after recovering access for security reasons.

Troubleshooting Multi-Factor Authentication

Since the EC2 instance is attempting to access the internet using HTTP (port 80) but is configured only to allow HTTPS (port 443) traffic, the security group needs adjustment:

Security Group Configuration: The outbound rules of the security group associated with the EC2 instance must allow traffic over HTTP. Add an outbound rule that enables port 80 to destination 0.0.0.0/0. This rule will allow the instance to send HTTP requests to any IP address on the internet.

Test Connectivity: After updating the security group, test the connectivity using the curl command again to ensure the configuration allows internet access via HTTP.

This change is necessary because the existing security group configuration does not permit outbound HTTP traffic, which is essential for accessing websites using HTTP.

For a disaster recovery (DR) plan with a 15-minute RTO and RPO, the most cost-effective steps include:

B: Configuring the Aurora cluster to replicate data to the DR region using the Aurora global database option. This allows continuous replication with typically low replication lag, meeting the 15-minute RPO requirement efficiently.

C: Pre-configuring the DR region with an ALB and an Auto Scaling group using the same configuration as the primary region. This ensures readiness and quick failover, aligning with the 15-minute RTO target.

These steps provide a robust disaster recovery setup that minimizes downtime and data loss while optimizing costs by using built-in AWS functionalities and avoiding over-provisioning.

Using a Route 53 Resolver outbound endpoint allows DNS queries for on-premises hosts to be forwarded to the on-premises DNS server over the Direct Connect connection, minimizing maintenance and automating name resolution without the need for manual entry or file management.
