SOA-C02 Exam Dumps - AWS Certified SysOps Administrator - Associate (SOA-C02)

To remotely connect to the EC2 instance, the SysOps administrator must ensure that the security group allows inbound SSH traffic.

Modify the Security Group:

Navigate to the EC2 console.

Select the security group associated with the EC2 instance.

Add an inbound rule to allow SSH traffic (TCP port 22) from the SysOps administrator's IP address.

Example rule:

Type: SSH

Protocol: TCP

Port Range: 22

Step-by-Step Explanation:

Understand the Problem:

Each Lambda function generates 1 GB of log data daily in its own CloudWatch Logs log group.

The security team needs a count of application errors, grouped by type, across all log groups.

Analyze the Requirements:

Aggregate and analyze log data across multiple log groups.

Count and group errors by type.

Evaluate the Options:

Option A: Perform a CloudWatch Logs Insights query.

CloudWatch Logs Insights allows querying and analyzing log data.

The stats command and count function can aggregate and count errors across log groups.

Option B: Perform a CloudWatch Logs search with groupby and count.

CloudWatch Logs search does not support these functions; Logs Insights is needed for advanced queries.

Option C: Perform an Amazon Athena query.

Athena can query data in S3 but is not directly applicable to CloudWatch Logs.

Option D: Perform an Amazon RDS query.

RDS queries are for database data, not applicable to log data in CloudWatch.

Select the Best Solution:

Option A: CloudWatch Logs Insights is designed for querying and analyzing log data, making it the appropriate choice for counting and grouping errors.

CloudWatch Logs Insights provides powerful querying capabilities to aggregate and analyze log data, including counting and grouping errors.

Retain the Security Group:

When deleting a CloudFormation stack, you can specify resources to be retained instead of deleted.

Steps:

Go to the AWS Management Console.

Navigate to CloudFormation and select the stack.

Choose to delete the stack.

In the deletion options, specify that the security group should be retained.

This will delete the stack but keep the security group, ensuring no impact on other applications.

To deploy and manage an identical Amazon VPC configuration across multiple AWS accounts efficiently:

AWS CloudFormation Template: Create a CloudFormation template that defines the VPC configuration. This template should include all necessary resources like subnets, route tables, internet gateways, etc.

Use CloudFormation StackSets: Utilize AWS CloudFormation StackSets to manage the deployment of the VPC template across the 50 AWS accounts. StackSets allow you to specify management and target accounts, automate deployments, and ensure consistency across all accounts.

Updating VPCs: When updates are required, modify the CloudFormation template and update the stack set. This will automatically apply the changes to all VPCs in the target accounts, ensuring uniformity and reducing operational overhead.

This method provides a centralized, consistent, and scalable way to manage resources across multiple AWS accounts, greatly simplifying the administration and ensuring compliance with organizational standards.

To minimize costs while moving from EC2 instances to AWS Fargate, Compute Savings Plans are the most flexible and cost-effective option. Compute Savings Plans apply to a variety of compute services including AWS Fargate, Amazon EC2, and AWS Lambda, allowing for greater flexibility in managing costs as the company transitions to using only Fargate.

Compute Savings Plans:

Savings Plans provide significant savings over On-Demand pricing, up to 66% savings.

Compute Savings Plans offer the flexibility to move across instance types, AWS Regions, and operating systems.

Payment Options:

The No Upfront payment option provides the most flexibility and avoids large upfront capital expenditures.

The Partial Upfront payment option offers more savings but requires an initial payment.

1-Year Term:

A 1-year term is suitable for the company's 6-month transition period, allowing for cost savings without a long-term commitment.

AWS Single Sign-On (AWS SSO) provides a centralized interface to manage SSO access to multiple AWS accounts and business applications. AWS SSO integrates with AWS Organizations and supports SAML 2.0 identity providers, making it an ideal solution for centrally managing user access and permissions across multiple AWS accounts.

AWS Single Sign-On (AWS SSO):

AWS SSO allows you to manage SSO access and user permissions to all of your AWS accounts and applications.

It integrates seamlessly with AWS Organizations.

Integration with SAML 2.0 IdP:

AWS SSO supports integration with third-party SAML 2.0 identity providers.

This allows centralized management of user identities and access.

Steps to Implement:

Enable AWS SSO in your AWS Organizations management account.

Configure AWS SSO to connect with your third-party SAML 2.0 IdP.

Assign user permissions and roles for each AWS account through AWS SSO.

Increasing the IOPS for the gp3 EBS volume will address the high VolumeQueueLength by allowing more read/write operations, directly improving performance for I/O-intensive tasks. ElastiCache and enhanced networking do not directly affect EBS performance for this issue.
