In AWS, each subnet has a fixed CIDR block, and the number of available IP addresses is determined by this block. For example, a /28 subnet provides 16 IP addresses, but 5 are reserved by AWS, leaving 11 usable IPs.

Since the subnet is already at capacity:

Create a New Subnet:

Choose a CIDR block that doesn't overlap with existing subnets.

Ensure it's within the VPC's CIDR range.

Launch additional EC2 instances in this new subnet.

This approach allows for the deployment of more instances without modifying existing subnets.

"Network Load Balancer is optimized to handle sudden and volatile traffic patterns while using a single static IP address per Availability Zone."

For an application that must scale to millions of requests per second and requires a single static IP address for each Availability Zone, a Network Load Balancer (NLB) is the most suitable option. NLBs are designed for high-performance, low-latency networking, and they support static IP addresses for each Availability Zone, making it ideal for volatile traffic patterns. Option D is the correct choice. AWS provides extensive documentation on NLB capabilities and configurations that suit these requirements AWS Network Load Balancer.

Amazon S3 Batch Operations is a feature that lets you perform large-scale batch operations on S3 objects. It is the most operationally efficient way to replace a tag on all objects in an S3 bucket.

Create an S3 Batch Operations Job:

Open the Amazon S3 console at Amazon S3 Console.

Navigate to Batch Operations and create a new job.

Specify the Operation:

Choose the operation to replace all object tags.

Provide a manifest that lists the objects in the bucket. You can generate this manifest using an S3 inventory report.

Execute the Job:

Review the job configuration and submit it.

Monitor the job execution to ensure all tags are replaced as specified.

Using S3 Batch Operations automates the process and minimizes manual effort.
