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

To address the performance issues of a CPU-heavy application running on a t2.large EC2 instance, the best course of action is to upgrade to a compute-optimized instance. Compute-optimized instances provide a higher ratio of CPU resources compared to memory, making them ideal for applications that require high CPU performance.

Upgrade to a Compute-Optimized Instance:

Identify a suitable compute-optimized instance type, such as the c5.large, which offers better CPU performance compared to the t2.large.

Stop the current EC2 instance and change the instance type to the chosen compute-optimized instance.

To restrict resource creation in unapproved regions across multiple AWS accounts efficiently, combining SCPs and Control Tower settings is effective:

SCP for Regional Restrictions: Create and apply an SCP that explicitly denies access to AWS services in unapproved regions. This policy will enforce region-based restrictions at the organizational unit or account level.

Control Tower Regional Governance: Adjust the settings in AWS Control Tower's landing zone to include governance for approved regions. This helps in maintaining a standard configuration that aligns with organizational policies regarding AWS regions.

To host a static website on Amazon S3, the SysOps administrator needs to configure the bucket for public access and set up the static website hosting. Here's how to complete this process:

Turn off "Block all public access": Amazon S3 buckets have "Block all public access" settings enabled by default for security. Since the webpage needs to be accessible publicly, this setting must be disabled. This step is crucial to allow public read access to the web content.

Set a bucket policy: After disabling "Block all public access," set a bucket policy that explicitly allows public read access to the S3 bucket. This policy should allow the s3:GetObject action for everyone, which can be set by specifying "Principal": "*". This policy ensures that anyone can view the webpage but does not grant permissions to modify or delete the content.

Create an index.html document and configure static website hosting: The next step is to create an index.html file, which will serve as the entry point of the website. After creating this file, upload it to the bucket. Then, configure the bucket for static website hosting through the S3 management console. This setting enables the S3 bucket to serve the webpage directly from the index.html file.

Combining these actions, the S3 bucket will be properly configured to host and serve the static website with minimal operational overhead and maximum accessibility.
