A space exploration firm possesses a collection of telescopes that take many photographs and data of the night sky. The pictures and data are processed on an AWS Fargate application that is allocated to a target group by an Application Load Balancer (ALB). The program is accessible at https://space.example.com.
Additionally, scientists demand a custom-built application that is hosted on many Amazon EC2 instances inside an Auto Scaling group. This application will be accessible at the following link: https://space.example.com/meteor. The firm need a system that can grow automatically from a low number of requests overnight to a high volume of demands during a future meteor shower.
What is the MOST OPTIMAL option that satisfies these requirements?
Answer : B
A company runs a large-scale application on a feel of Amazon EC2 instances that ate distributed across several VPCs A Network Load Balancer (NLB) in a separate VPC routes traffic to the EC2 instances The NLB's VPC is peered to all the application VPCs
The application must process millions of requests each minute during times of peak utilization Users are reporting that the connections to the application are failing during peak times Monitoring shows an increase in port allocation errors on the NLB.
Which action will solve this issue with the LEAST change to the architecture?
Answer : C
A financial services company receives real-time stock quotes in its ingestion VPC. The company plans to perform customer-specific data analysis on the stock quotes in various VPCs. The stock quotes must be distributed simultaneously from Amazon EC2 instances in the ingestion VPC to EC2 instances in the data analysis VPCs
Which set of configuration steps should the company lake to meet these requirements?
Answer : C
Multicast is a communication protocol used for delivering a single stream of data to multiple receiving computers simultaneously. Transit Gateway supports routing multicast traffic between subnets of attached VPCs, and it serves as a multicast router for instances sending traffic destined for multiple receiving instances.
A company hosts several applications in the AWS Cloud across multiple VPCs that are connected to a transit gateway Redundant AWS Direct Connect connections and a Direct Connect gateway provide private network connectivity lo the company's on-premises environment
During a maintenance window, the networking team adds eight VPCs The application management team notices that there is no reachability between the newly created VPCs and the on-premises environment Connectivity between all VPCs through the transit gateway is working as expected.
Which of the following are possible causes of the connectivity issues? (Choose TWO)
A company's developers wrote an AWS Lambda function to modify existing private route tables in response to a security appliance's auto scaling events. The Lambda function will be invoked on lifecycle hooks for an Auto Scaling group and Is configured to run in a VPC The developers are unsure if the following 1AM policy provides sufficient permissions to be used as an execution role for this Lambda function.
The developers ask a network engineer to review the permissions.
Which set of permissions should the network engineer add lo the policy?
Answer : C
