An application stores data in an Amazon RDS MySQL DB instance. The database traffic primarily consists of read queries, which are overwhelming the current database. A Solutions Architect wants to scale the database. What combination of steps will achieve the goal? (Choose two.)
A. Add the MySQL database instances to an Auto Scaling groupAn application has components running in a public subnet and a private subnet. The components within the private subnet must connect to the internet to receive updates. How should this be accomplished without moving the components into a public subnet?
A. Add an internet gateway to the private subnet and update the private subnet route table.An application has a web tier that runs on EC2 instances in a public subnet. The application tier instances run in private subnets across two Availability Zones. All traffic is IPv4 only, and each subnet has its own custom route table.
A new feature requires that application tier instances can call an external service over the Internet; however, they must still not be accessible to Internet traffic.
What should be done to allow the application servers to connect to the Internet, maintain high availability, and minimize administrative overhead?
A. Add an Amazon egress-only internet gateway to each private subnet. Alter each private subnet's route table to include a route from 0.0.0.0/0 to the egress-only internal gateway in the same Availability Zone.An application stores data in an Amazon RDS PostgreSQL Multi-AZ database instance. The ratio of read requests to write requests is about 2 to 1. Recent increases in traffic are causing very high latency. How can this problem be corrected?
A. Create a similar RDS PostgreSQL instance and direct all traffic to it.A Solutions Architect is designing a solution to store a large quantity of event data in Amazon S3. The Architect anticipates that the workload will consistently exceed 100 requests each second. What should the Architect do in Amazon S3 to optimize performance?
A. Randomize a key name prefix.A company will host a static website within an Amazon S3 bucket. The website will serve millions of users globally, and the company wants to minimize data transfer costs. What should the Solutions Architect do to ensure costs are kept to a minimum?
A. Implement an AWS Auto Scaling group for the website to ensure it grows with use.Your company is in the process of developing a next generation pet collar that collects biometric information to assist families with promoting healthy lifestyles for their pets Each collar will push 30kb of biometric data In JSON format every 2
seconds to a collection platform that will process and analyze the data providing health trending information back to the pet owners and veterinarians via a web portal Management has tasked you to architect the collection platform ensuring
the following requirements are met.
Provide the ability for real-time analytics of the inbound biometric data
Ensure processing of the biometric data is highly durable. Elastic and parallel
The results of the analytic processing should be persisted for data mining
Which architecture outlined below win meet the initial requirements for the collection platform?
A. Utilize S3 to collect the inbound sensor data analyze the data from S3 with a daily scheduled Data Pipeline and save the results to a Redshift Cluster.A company hosts a two-tier application that consists of a publicly accessible web server that communicates with a private database. Only HTTPS port 443 traffic to the web server must be allowed from the Internet. Which of the following options will achieve these requirements? (Choose two.)
A. Security group rule that allows inbound Internet traffic for port 443.A company's Data Analysis team needs to perform real-time complex queries against a database. As the team grows, the complex queries are slowing down production transactions. The current environment has an Amazon RDS database with the largest instance type and is still experiencing performance issues.
Which solution will reduce costs and resolve the performance issues?
A. Implement an Amazon RDS Read Replica of the production database to be used by the Data Analysis team and reduce the RDS database instance size.A Solutions Architect is designing a disaster recovery (DR) environment in a separate AWS region from an application's primary workload. The application uses a multi-tier architecture, and only the RDS instance will have frequent changes.
The application installation process takes 60 minutes on average. The disaster recovery plan must have an RPO of less than 90 minutes and an RTO of less than 30 minutes.
Which of the following would enable the Solutions Architect to meet these requirements? (Choose two.)
A. An Aurora instance as the primary database with a read replica in the DR region.Nowadays, the certification exams become more and more important and required by more and more enterprises when applying for a job.
