Question 1

A company that operates a web application on premises is preparing to launch a newer version of the application on AWS The company needs to route requests to either the AWS-hosted or the on-premises-hosted application based on the URL query string The on-premises application Is not available from the Internet, and a VPN connection Is established between Amazon VPC and the company's data center. The company wants to use an Application Load Balancer (ALB) for this launch Which solution meets these requirements''

A.Use one ALB with two AWS Auto Scaling groups one for the AWS resource and one for on premises Add hosts to each Auto Scaling group Route with Amazon Route 53 based on the URL query string
B.Use two ALBs: one for on premises and one for the AWS resource Add hosts to each target group of each ALB Route with Amazon Route 53 based on the URL query string
C.Use one ALB with two target groups one for the AWS resource and one for on premises Add hosts to each target group of the ALB Configure listener rules based on the URL query string
D.Use Mo ALBs; one for on premises and one for the AWS resource Add hosts to the target group of each ALB Create a software router on an EC2 instance based on the URL query string

Question 2

A company has two VPCs that are located in the us-west-2 Region within the same AWS account. The company needs to allow network traffic between these VPCs. Approximately 500 GB of data transfer will occur between the VPCs each month.
What is the MOST cost-effective solution to connect these VPCs?

A.Implement AWS Transit Gateway to connect the VPCs. Update the route tables of each VPC to use the transit gateway for inter-VPC communication.
B.Implement an AWS Site-to-Site VPN tunnel between the VPCs. Update the route tables of each VPC to use the VPN tunnel for inter-VPC communication.
C.Set up a VPC peering connection between the VPCs. Update the route tables of each VPC to use the VPC peering connection for inter-VPC communication.
D.Set up a 1 GB AWS Direct Connect connection between the VPCs. Update the route tables of each VPC to use the Direct Connect connection for inter-VPC communication.

Question 3

What would be the best way to retrieve the public IP address of your EC2 instance using the CLI?

A.Using tags
B.Using traceroute
C.Using ipconfig
D.Using instance metadata

Question 4

A company wants to migrate its web application to AWS. The legacy web application consists of a web tier, an application tier, and a MySQL database. The re-architected application must consist of technologies that do not require the administration team to manage instances or clusters.
Which combination of services should a solutions architect include in Ihe overall architecture? (Select TWO)

A.Amazon Aurora Serverless
B.Amazon EC2 Spot Instances
C.Amazon RDS for MySQL
D.Amazon Elasticsearch Service (Amazon ES)
E.AWS Fargate

Question 5

A company's applications run on Amazon EC2 instances in Auto Scaling groups. The company notices that its applications experience sudden traffic increases on random days of the week The company wants to maintain application performance during sudden traffic increases.
Which solution will meet these requirements MOST cost-effectively?

A.Use manual scaling to change the size of the Auto Scaling group.
B.Use predictive scaling to change the size of the Auto Scaling group.
C.Use dynamic scaling to change the size of the Auto Scaling group.
D.Use schedule scaling to change the size of the Auto Scaling group

Correct Answer: C

Explanation
Dynamic scaling is a type of autoscaling that automatically adjusts the number of EC2 instances in an Auto Scaling group based on demand or load. It uses CloudWatch alarms to trigger scaling actions when a specified metric crosses a threshold. It can scale out (add instances) or scale in (remove instances) as needed1. By using dynamic scaling, the solution can maintain application performance during sudden traffic increases most cost-effectively.
A: Use manual scaling to change the size of the Auto Scaling group. This solution will not meet the requirement of maintaining application performance during sudden traffic increases, as manual scaling requires users to manually increase or decrease the number of instances through a CLI or console. It does not respond automatically to changes in demand or load B: Use predictive scaling to change the size of the Auto Scaling group. This solution will not meet the requirement of most cost-effectiveness, as predictive scaling uses machine learning and artificial intelligence tools to evaluate traffic loads and anticipate when more or fewer resources are needed. It performs scheduled scaling actions based on the prediction, which may not match the actual demand or load at any given time. Predictive scaling is more suitable for scenarios where there are predictable traffic patterns or known changes in traffic loads3.
D: Use schedule scaling to change the size of the Auto Scaling group. This solution will not meet the requirement of maintaining application performance during sudden traffic increases, as schedule scaling performs scaling actions at specific times that users schedule. It does not respond automatically to changes in demand or load. Schedule scaling is more suitable for scenarios where there are predictable traffic drops or spikes at specific times of the day.
