A solutions architect needs to design a network that will allow multiple Amazon EC2 instances to access a common data source used for mission-critical data that can be accessed by all the EC2 instances simultaneously. The solution must be highly scalable, easy to implement and support the NFS protocol. Which solution meets these requirements?
Question 312
A company hosts its application using Amazon Elastic Container Service (Amazon ECS) and wants to ensure high availability. The company wants to be able to deploy updates to its application even if nodes in one Availability Zone are not accessible. The expected request volume for the application is 100 requests per second, and each container task is able to serve at least 60 requests per second. The company set up Amazon ECS with a rolling update deployment type with the minimum healthy percent parameter set to 50% and the maximum percent set to100%. Which configuration of tasks and Availability Zones meets these requirements?
Question 313
A solutions architect wants all new users to have specific complexity requirements and mandatory rotation periods for IAM user passwords. What should the solutions architect do to accomplish this?
Question 314
A company wants to improve the availability and performance of its hybrid application. The application consists of a stateful TCP-based workload hosted onAmazon EC2 instances in different AWS Regions and a stateless UOP-based workload hosted on premises. Which combination of actions should a solutions architect take to improve availability and performance? (Choose two.)
Question 315
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-DemandInstances and will automatically scale across multiple Availability Zones. The EC2 instances will scale up and down frequently throughout the day. An ApplicationLoad 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?
Question 316
A company has an ecommerce application running in a single VPC. The application stack has a single web server and an Amazon RDS Multi-AZ DB instance. The company launches new products twice a month. This increases website traffic by approximately 400% for a minimum of 72 hours. During product launches, users experience slow response times and frequent timeout errors in their browsers. What should a solutions architect do to mitigate the slow response times and timeout errors while minimizing operational overhead?
Question 317
A solutions architect is designing an architecture to run a third-party database server. The database software is memory intensive and has a CPU-based licensing model where the cost increases with the number of vCPU cores within the operating system. The solutions architect must select an Amazon EC2 instance with sufficient memory to run the database software, but the selected instance has a large number of vCPUs. The solutions architect must ensure that the vCPUs will not be underutilized and must minimize costs. Which solution meets these requirements?
Question 318
A company receives 10 TB of instrumentation data each day from several machines located at a single factory. The data consists of JSON files stored on a storage area network (SAN) in an on-premises data center located within the factory. The company wants to send this data to Amazon S3 where it can be accessed by several additional systems that provide critical near-real-lime analytics. A secure transfer is important because the data is considered sensitive. Which solution offers the MOST reliable data transfer?
Question 319
A company is creating a web application that will store a large number of images in Amazon S3. The images will be accessed by users over variable periods of time. The company wants to: - Retain all the images - Incur no cost for retrieval. - Have minimal management overhead. - Have the images available with no impact on retrieval time. Which solution meets these requirements?
Question 320
A company hosts more than 300 global websites and applications. The company requires a platform to analyze more than 30 TB of clickstream data each day. What should a solutions architect do to transmit and process the clickstream data?
