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

To maintain a documented trail of any changes made to the security groups and receive notifications, AWS Config is the best solution.

AWS Config:

AWS Config continuously monitors and records your AWS resource configurations and allows you to automate the evaluation of recorded configurations against desired configurations.

You can set up AWS Config to record changes to your security groups.

Setting Up AWS Config:

Open the AWS Config console and choose "Set up AWS Config."

Select the resource types you want to record (in this case, security groups).

Specify an Amazon S3 bucket to store configuration snapshots and history files.

Notifications:

Create an Amazon SNS topic for notifications about configuration changes.

Subscribe the SysOps administrator's email address to the SNS topic.

Setting Up AWS Config

Objective:

Resolve the HTTP 403 (Access Denied) error for the public S3 static website.

Root Cause:

By default, S3 buckets are private, and public access is blocked due to the Block Public Access settings.

Additionally, a bucket policy is needed to allow public access to the objects.

Solution Implementation:

Step 1: Turn off Block Public Access:

Navigate to the Permissions tab of the S3 bucket in the AWS Management Console.

Turn off the Block Public Access settings by disabling the following:

Block public access to buckets and objects via ACLs.

Block public access to buckets and objects via bucket policies.

Step 2: Add a Bucket Policy for Public Access:

Add a policy allowing GetObject for public access:

{

"Version": "2012-10-17",

"Statement": [

{

"Effect": "Allow",

"Principal": "*",

"Action": "s3:GetObject",

"Resource": "arn:aws:s3:::/*"

}

]

}

Step 3: Test Access:

Confirm that the website is accessible via the public URL.

Bucket Policies for Static Websites:Bucket Policy Examples

Why Other Options Are Incorrect:

Option A: Route 53 is not required to resolve the 403 error; the issue is with S3 bucket permissions.

Option C: Editing file permissions alone will not work; bucket permissions must also allow public access.

Option D: PutObject permissions are unnecessary for serving a static website.

AWS Compute Optimizer recommends optimal AWS resources for your workloads to reduce costs and improve performance. It provides actionable recommendations to help you choose the right EC2 instances and AWS Lambda configurations.

Access AWS Compute Optimizer:

Open the AWS Compute Optimizer console at AWS Compute Optimizer Console.

Review the recommendations for your EC2 instances and AWS Lambda functions.

Implement Recommendations:

Analyze the recommendations, which might include resizing instances, changing instance types, or modifying Lambda memory settings.

geolocation "Geolocation routing lets you choose the resources that serve your traffic based on the geographic location of your users, meaning the location that DNS queries originate from. For example, you might want all queries from Europe to be routed to an ELB load balancer in the Frankfurt region."

Could be confused with geoproximity - "Geoproximity routing lets Amazon Route 53 route traffic to your resources based on the geographic location of your users and your resources. You can also optionally choose to route more traffic or less to a given resource by specifying a value, known as a bias. A bias expands or shrinks the size of the geographic region from which traffic is routed to a resource" the use case is not needed as per question.

To change an EC2 instance type (e.g., from t3.large to c5.large):

You must stop the instance, change the instance type, then start it again.

From EC2 instance resize documentation:

Changing the instance type requires stopping and starting the instance, unless you're using Elastic Beanstalk or Auto Scaling groups with launch templates.

RDS Proxy acts as an intermediary between your application and an RDS database. RDS Proxy establishes and manages the necessary connection pools to your database so that your application creates fewer database connections. Your Lambda functions interact with RDS Proxy instead of your database instance. It handles the connection pooling necessary for scaling many simultaneous connections created by concurrent Lambda functions. This allows your Lambda applications to reuse existing connections, rather than creating new connections for every function invocation.

Check "Database proxy for Amazon RDS" section in the link to see how RDS proxy help Lambda handle huge connections to RDS MySQL https://aws.amazon.com/blogs/compute/using-amazon-rds-proxy-with-aws-lambda/

A mount target provides an IP address for an NFSv4 endpoint at which you can mount an Amazon EFS file system. You mount your file system using its Domain Name Service (DNS) name, which resolves to the IP address of the EFS mount target in the same Availability Zone as your EC2 instance. You can create one mount target in each Availability Zone in an AWS Region. If there are multiple subnets in an Availability Zone in your VPC, you create a mount target in one of the subnets. Then all EC2 instances in that Availability Zone share that mount target. https://docs.aws.amazon.com/efs/latest/ug/how-it-works.html

Amazon FSx for Windows File Server provides a fully managed, highly available, and native Windows file system compatible with the SMB protocol, ideal for Windows workloads requiring shared access.

Multi-AZ File System: Ensures high availability across multiple Availability Zones.

Native Windows Capabilities: Allows instances to map file shares and access files using Windows storage features, offering strong consistency and performance for shared files.

Other options, like Amazon S3 and Amazon EFS, either lack native Windows integration or do not offer the desired consistency and high availability for shared file systems in a Windows environment.
