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

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.

 Enable Access Logging for the ALB:

Access logging provides detailed information about requests sent to your load balancer.

Steps:

Go to the AWS Management Console.

Navigate to EC2 and select "Load Balancers."

Select your Application Load Balancer.

Under the "Attributes" tab, enable "Access logs."

Specify an S3 bucket where the logs will be saved.

Enable Access Logs for Your Load Balancer

 Use Amazon Athena to Query the ALB Logs:

Athena allows you to run SQL queries on data stored in S3.

Steps:

Go to the AWS Management Console.

Navigate to Athena.

Create a table for the ALB logs using the appropriate schema.

Run queries to calculate the total bytes sent and received, grouped by the target

field.

Example query:

SELECT target, SUM(received_bytes) as total_received, SUM(sent_bytes) as total_sent

FROM alb_logs

GROUP BY target, port

Step-by-Step Explanation:

Understand the Problem:

Ensure all users in the organization have read-level access to a specific S3 bucket.

The data should not be accessible outside the organization.

Analyze the Requirements:

Grant read access to users within the organization.

Prevent access from outside the organization.

Evaluate the Options:

Option A: Specify "*" as the principal and PrincipalOrgId as a condition.

This grants access to all AWS principals but restricts it to those within the specified organization using the PrincipalOrgId condition.

Option B: Specify all account numbers as the principal.

This is impractical for a large organization and requires constant updates if accounts are added or removed.

Option C: Specify PrincipalOrgId as the principal.

The PrincipalOrgId condition must be used within a policy, not as a principal.

Option D: Specify the organization's management account as the principal.

This grants access only to the management account, not to all users within the organization.

Select the Best Solution:

Option A: Using "*" as the principal with the PrincipalOrgId condition ensures all users within the organization have the required access while preventing external access.

Using "*" as the principal with the PrincipalOrgId condition efficiently grants read access to the S3 bucket for all users within the organization.
