Amazon Web Services SOA-C02 Exam With Confidence Using Practice Dumps

To send an email notification when an ACM certificate has less than 14 days until expiration, the most operationally efficient solution is to create an Amazon EventBridge rule that directly monitors AWS ACM for certificate expiry details. EventBridge can capture aws.acm events related to certificate expiration and evaluate the DaysToExpiry metric directly. Configure the rule to send notifications to an Amazon SNS topic when DaysToExpiry is less than 14, and subscribe the necessary email addresses to this SNS topic. This approach avoids the need for custom metrics or manual monitoring, providing a streamlined and automatic notification system. Option B is the correct answer as it leverages native integration between ACM, EventBridge, and SNS for minimal operational overhead. More details on EventBridge rules can be found in AWS documentation EventBridge Rules.

To give the application the ability to resolve internal domain names, the SysOps administrator should create an Amazon Route 53 Resolver outbound endpoint and configure it to forward DNS queries to the on-premises DNS server.

Route 53 Resolver Outbound Endpoint:

An outbound endpoint enables DNS queries to be forwarded from AWS resources in a VPC to an on-premises DNS server.

Steps to Implement:

In the Route 53 console, create a new outbound endpoint in the VPC.

Configure the outbound endpoint with the IP address of the on-premises DNS server.

Update the VPC DNS settings to use the Route 53 Resolver.

Step-by-Step Explanation:

AWS Budgets Overview:

AWS Budgets enables you to set custom cost and usage budgets, and it provides alerts when you exceed those thresholds. It is designed for cost management with minimal operational overhead.

Recurring Cost Budget Creation:

Go to the AWS Budgets Console.

Select Create a budget.

Choose the Cost budget option.

Define whether this budget tracks actual costs or forecasted costs (you will create two budgets, one for each).

Configure the Budget Thresholds:

Set your budget thresholds for both actual costs and forecasted costs.

For example:

Actual Costs Alert: Budget = $1000, Alert at 80% usage ($800).

Forecasted Costs Alert: Budget = $1000, Alert at forecasted usage exceeding 80% ($800).

Alert Configuration:

In the budget creation process, enable Notifications and Actions.

Specify the email addresses or an Amazon SNS Topic to receive alerts.

Set up alerts for both:

Actual Cost Exceeding Budget.

Forecasted Cost Exceeding Budget.

Amazon SNS Setup:

If using an SNS topic, ensure an Amazon SNS topic is created.

Grant appropriate permissions for the Budget service to publish to the SNS topic.

Add subscribers (e.g., email addresses or endpoints) to the SNS topic.

Automation and Monitoring:

Once set up, AWS Budgets continuously monitors actual and forecasted costs.

Alerts are sent automatically when thresholds are breached, reducing manual overhead and reliance on periodic monitoring.

Why This is the Best Option (Least Operational Overhead):

AWS Budgets directly integrates with SNS, allowing real-time alerts without building custom workflows or parsing reports.

It is a native AWS service specifically designed for cost tracking, minimizing complexity and setup time.

No custom code or additional services like Lambda or Step Functions are required, reducing operational maintenance.
