At ValidExamDumps, we consistently monitor updates to the Amazon SOA-C02 exam questions by Amazon. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the Amazon AWS Certified SysOps Administrator - Associate exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by Amazon in their Amazon SOA-C02 exam. These outdated questions lead to customers failing their Amazon AWS Certified SysOps Administrator - Associate exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the Amazon SOA-C02 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
The SysOps administrator must dynamically reference the latest AMI ID from Systems Manager Parameter Store in CloudFormation templates for new AMI versions.
Options (Select THREE):
To allow CloudFormation templates in all accounts within the organization to reference the latest AMI ID:
Parameter Store in Standard Tier: Storing the AMI ID in Systems Manager Parameter Store provides a central and easy-to-update source.
Enable Resource Sharing with Organizations: This allows the parameter to be shared across accounts in the organization.
Resource Share in AWS RAM: AWS Resource Access Manager (RAM) can be used to share the parameter with the entire organization, allowing other accounts to access the AMI ID.
Using the standard tier in Parameter Store is sufficient, and an EventBridge rule with Lambda for updating AMIs would add unnecessary complexity.
A company is using Amazon Elastic File System (Amazon EFS) to share a file system among several Amazon EC2 instances. As usage increases, users report that file retrieval from the EFS file system is slower than normal.
Which action should a SysOps administrator take to improve the performance of the file system?
To improve the performance of an Amazon Elastic File System (EFS) when users report slower file retrieval times, configuring the file system for Provisioned Throughput is an effective solution.
Login to AWS Management Console:
Open the Amazon EFS console at Amazon EFS Console.
Select the File System:
In the EFS console, select the file system that you want to modify.
Modify Throughput Settings:
Choose File system policy and then Manage file system policy.
Under Throughput mode, select Provisioned Throughput.
Specify the desired throughput in MiB/s based on your application's needs.
Apply Changes:
Save the changes to apply the new throughput settings to the file system.
A company's SysOps administrator manages a fleet of hundreds of Amazon EC2 instances that run Windows-based workloads and Linux-based workloads. Each EC2 instance has a tag that identifies its operating system. All the EC2 instances run AWS Systems Manager Session Manager.
A zero-day vulnerability is reported, and no patches are available. The company's security team provides code for all the relevant operating systems to reduce the risk of the vulnerability. The SysOps administrator needs to implement the code on the EC2 instances and must provide a report that shows that the code has successfully run on all the instances.
What should the SysOps administrator do to meet these requirements as quickly as possible?
AWS Systems Manager Run Command provides an efficient method to execute administrative tasks on EC2 instances. This solution will minimize the time and complexity involved:
Select Document: Choose AWS-RunShellScript for Linux-based instances or AWS-RunPowerShellScript for Windows-based instances.
Configure Command: Enter the mitigation script provided by the security team into the command document.
Target Instances: Use the tagging system to target only the instances that match the specific OS as identified by their tags.
Execute Command: Run the command across the targeted instances.
Verification and Reporting: The command history in Systems Manager will serve as evidence of execution and success, which can be reported back to the security team.
A company needs to track spending in its AWS account. The company must receive a notification when current costs and forecasted costs exceed specific thresholds. Which solution will meet these requirements with the LEAST operational overhead?
Step-by-Step
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.

A company has an application that is running on Amazon EC2 instances in a VPC. The application needs access to download software updates from the internet. The VPC has public subnets and private signets. The company's security policy requires all ECS instances to be deployed in private subnets
What should a SysOps administrator do to meet those requirements?
To ensure that EC2 instances in private subnets can access the internet for software updates while complying with the security policy that requires instances to be in private subnets, you should use a NAT gateway. A NAT gateway allows instances in private subnets to initiate outbound traffic to the internet but prevents the internet from initiating connections to those instances.
Steps:
Create a NAT Gateway:
Open the Amazon VPC console.
In the navigation pane, choose 'NAT Gateways'.
Choose 'Create NAT Gateway'.
Select the public subnet where you want to create the NAT gateway.
Choose an Elastic IP address for the NAT gateway.
Choose 'Create a NAT Gateway'.
Update the Route Table for Private Subnets:
Open the Amazon VPC console.
In the navigation pane, choose 'Route Tables'.
Select the route table associated with your private subnets.
Choose the 'Routes' tab and then 'Edit routes'.
Add a route with the destination 0.0.0.0/0 and the target as the NAT gateway ID.
Save the changes.
This setup ensures that instances in private subnets can access the internet via the NAT gateway in the public subnet.
