Amazon Web Services Updated SOA-C02 Exam Questions and Answers by nylah

The best combination of steps to meet this requirement is to sign in to the new account by using root user credentials and change the support plan, and to create an IAM user that has administrator privileges in the new account.

Signing in to the new account by using root user credentials will allow the SysOps administrator to access the account and change the support plan to AWS Business Support. Additionally, creating an IAM user that has administrator privileges in the new account will ensure that the SysOps administrator has the necessary access to manage the account and make changes to the support plan if necessary.

To transition the Amazon Elasticsearch Service (Amazon ES) domain to a highly available, production-grade deployment:

Cluster Configuration:

Use a cluster of six data nodes to handle data ingestion and querying.

Distribute these nodes across three Availability Zones (AZs) for high availability and fault tolerance.

When troubleshooting inability to access an EC2 instance from the internet, you should:

A: Verify that the security group rules allow inbound HTTP and HTTPS traffic on ports 80 and 443. Security groups act as a virtual firewall to control the traffic to instances.

D: Check that outbound rules in the network ACL allow traffic for ephemeral ports 1024-65535. This is crucial for return traffic from web requests, which typically use these higher port numbers for responses.

E: Confirm that any software-based firewalls on the instance (such as Windows Firewall or iptables in Linux) are configured to allow inbound traffic on HTTP and HTTPS. These steps will ensure that the web server is correctly configured to receive and respond to web traffic from the internet. AWS provides guidelines on these configurations in their documentation on security groups EC2 Security Groups and network ACLs Network ACLs.

To enforce the use of approved EC2 instance configurations across different business units efficiently:

AWS Service Catalog: Utilize AWS Service Catalog to manage and govern commonly deployed IT services. Create a catalog of pre-approved products (in this case, EC2 instance configurations).

Publish Products: Define and publish EC2 instance configurations as products within the Service Catalog. These products will incorporate all the necessary and approved configurations, options, and software.

Launch Constraints: Assign launch constraints to these products, ensuring that users can only launch EC2 instances as defined by the pre-approved configurations.

Control Access: Grant business units access only to the Service Catalog for provisioning EC2 instances. This ensures they use only those configurations that comply with company policies and standards.

This approach not only standardizes resource deployment but also simplifies management and enhances compliance across the organization.
