Utilize Amazon CloudWatch alarms to monitor CPU usage and network traffic and trigger scaling policies

Set up AWS Auto Scaling with a target tracking scaling policy, where the target value is the avergae CPU utilization of your Auto Scaling Group

Manually increase or decrease the size of the Amazon EC2 fleet in response to the demand surge

Convert the application to a serverless architecture by porting it to AWS Lambda, thereby removing the need for manual scaling

Configure AWS Lambda functions to monitor the Amazon EC2 instances and manually start and stop the instances based on the traffic patterns

A multinational corporate firm is analyzing its IT infrastructure to cope with unexpected demand situations and scaling issues. With critical applications not designed for the cloud, the development team in place cannot make any changes to these applications.

What would be your recommendation to handle this legacy application scaling requirement from the following options?

Run the application on Amazon EC2 instances with Auto Scaling and Elastic Load Balancing, connecting to an Amazon RDS Multi-AZ DB

Replace these application with other readily available applications on the AWS Marketplace that can handle the load more efficiently

Suggest the firm to rewrite the applications from scratch focusing on scalability and host them on EC2 instances

Utilize existing EC2 instances and run applications with Amazon Elastic Beanstalk and configure it for auto scaling

You have an application hosted on Amazon EC2 instances. You are assigned to design an authorization model that maximizes security. Select the best approach that meets the requirements.

Implement IAM roles and assign these to the EC2 instance which allows the applications running on the instance to access AWS resources

Implement resource-based policies on the EC2 instances to control the actions that can be performed on them

Create IAM groups and assign these to the EC2 instances to manage permissions across those instances

Create IAM users and assign them to the EC2 instances to grant them permission to access AWS resources

Utilize Amazon Cognito for user pool management and federate these users to use IAM roles to manage their access to AWS resources

A media streaming company is looking to optimize costs for its EC2 fleet used in content delivery. They are considering the use of on-demand versus spot instances. What should a Solutions Architect recommend to achieve the best balance between cost savings and reliability for their EC2 fleet?

Implement a scaling strategy that primarily uses reserved instances and supplements with on-demand instances during peak times

Rely solely on on-demand instances for their predictable pricing and guaranteed availability

Adopt spot instances exclusively to maximize cost savings across all workloads

Which AWS provides infrastructure security optimization recommendations?

AWS Price List Application Programming Interface (API)

Amazon Elastic Compute Cloud (Amazon EC2) Spot Fleet

A company is developing an e-commerce platform in its VPC and wants to ensure maximum security for all inbound and outbound traffic in its environment. The application consists of web servers in the public subnet and databases in the private subnet. (Choose TWO answers)

Implement Security Groups on each EC2 instance that allow traffic only on necessary ports from trusted IP addresses only

Use Network ACLs at the subnet level to allow traffic only on necessary ports and deny all other traffic

Replace NAT Gateways with Internet Gateways for better internet access in the private subnets

Place all the web servers and databases in the public subnets for easier access control

Move the databases to public subnets and attach IAM roles for secure access control

An e-commerce company wants to enforce multi-factor authentication (MFA) on their AWS environment to enhance security. They want to make sure that both their IAM users and root users are using MFA. As a solutions architect, which strategy would you suggest?

Enable MFA for both IAM users and root users to ensure maximum security across all levels

Do not enable MFA as it will add another layer of complexity to the user login process and can be bypassed

Enable MFA at the root account level only, as root users have the highest level of access

Enable MFA for only IAM users because root users do not access AWS frequently and this could cause inconvenience

A leading e-commerce company utilizes AWS to support its operations. They have a multi-tier architecture that functions within private and public subnets. The web servers are in the public subnet, while the database servers operate in a private subnet. The web servers and databases run in the same Availability Zone (AZ). The company is now looking to optimize its network segmentation strategy to enhance security and redundancy for both the web and database tiers. As a solutions architect, which recommendation would best serve the company's objectives?

Implement and Amazon EC2 Auto Sclung Group for the web servers and place it behing an Application Load Balancer that spans multiple Azs. Simultaneously, use Amazon RDS Multi-AZ DB instances for the database tier in the private subnets

Establish a NAT Gateway within the public subnet and ensure that all the internal traffic must nucleate through the NAT Gateway

Maintain the existing network architecture without implementing any changes

Set up a new private subnet in another AZ and relocate the database servers to this new subnet to segregate web servers and database servers
