A company has developed a database in Amazon RDS for MySQL. Due to increased support team is reporting slow reads against the DB instance and recommends adding a read replica.
Which combination of actions should a solutions architect take before implementing this change? (Select TWO.)
A. Enable binlog replication on the RDS master.A company has developed a new video game as a web application. The application is in a three-tier architecture in a VPC with Amazon RDS for MySQL In the database layer Several players will compete concurrently online. The game's developers want to display a top-10 scoreboard in near-real time and offer the ability to stop and restore the game while preserving the current scores. What should a solutions architect do to meet these requirements?
A. Set up an Amazon ElastiCache for Memcached cluster to cache the scores for the web application to displayA company needs to store 160TB of data for an indefinite of time. The company must be able to use standard SQL and business intelligence tools to query all of the data The data will be queried no more than twice each month. What is the MOST cost-effective solution that meets these requirements?
A. Store the data in Amazon Aurora Serverles with MySQL . Use an SQL client to query the data.A company wants to run an in-memory database for a latency-sensitive application that runs on Amazon EC2 instances. The application processes more than 100,000 transactions each minute and requires high network throughput. A solutions architect needs to provide a cost-effective network design that minimizes data transfer charges.
Which solution meets these requirements?
A. Launch all EC2 instances in the same Availability Zone within the same AWS Region. Specify a placement group with cluster strategy when launching EC2 instances.A solutions architect is designing the architecture of a new application being deployed to the AWS Cloud The application will run on Amazon EC2 On-Demand Instances and will automatically scale across multiple Availability Zones The EC2 instances will scale up and down frequently throughout the day.
An Application Load Balancer (ALB) will handle the load distribution The architecture needs to support distributed session data management The company is willing to make changes to code if needed.
What should the solutions architect do to ensure that the architecture supports distributed session data management?
A. Use Amazon ElastiCache to manage and store session dataA company wants to use AWS Systems Manager to manage a fleet ol Amazon EC2 instances. According to the company's security requirements, no EC2 instances can have internet access. A solutions architect needs to design network connectivity from the EC2 instances to Systems Manager while fulfilling this security obligation.
Which solution will meet these requirements?
A. Deploy the EC2 instances into a private subnet with no route to the internet.A media company stores video content in an Amazon Elastic Block Store (Amazon EBS) volume. A certain video file has become popular and a large number of users across the world are accessing this content. This has resulted in a cost
increase.
Which action will DECREASE cost without compromising user accessibility?
A. Change the EBS volume to Provisioned IOPS (PIOPS).A global company hosts its web application on Amazon EC2 instances behind an Application Load Balancer (ALB). The web application has static data and dynamic data. The company stores its static data in an Amazon S3 bucket. The company wants to improve performance and reduce latency for the static data and dynamic data. The company is using its own domain name registered with Amazon Route 53.
What should a solutions architect do to meet these requirements?
A. Create an Amazon CloudFront distribution that has the S3 bucket and the ALB as origins Configure Route 53 to route traffic to the CloudFront distribution.A company offers a food delivery service that is growing rapidly Because of the growth the company's order processing system is experiencing scaling problems during peak traffic hours. The current architecture includes the following:
1.
A group of Amazon EC2 instances that run in an Amazon EC2 Auto Scaling group to collect orders from the application
2.
Another group of EC2 instances that run in an Amazon EC2 Auto Scaling group to fulfill orders
3.
The order collection process occurs quickly, but the order fulfillment process can take longer Data must not be lost because of a scaling event
4.
A solutions architect must ensure that the order collection process and the order fulfillment process can both scale properly during peak traffic hours The solution must optimize utilization of the company's AWS resources
Which solution meets these requirements?
A. Use Amazon CloudWatch metrics to monitor the CPU of each instance in the Auto Scaling groups. Configure each Auto Scaling group's minimum capacity according to peak workload valuesA company wants to use a custom distributed application that calculates various profit and loss scenarios. To achieve this goal, the company needs to provide a network connection between its Amazon EC2 instances. The connection must minimize latency and must maximize throughput.
Which solution will meet these requirements?
A. Provision the application to use EC2 Dedicated Hosts of the same instance type.Nowadays, the certification exams become more and more important and required by more and more enterprises when applying for a job.
