A solutions architect is designing the architecture for a new web application. The application will run on AWS Fargate containers with an Application Load Balancer (ALB) and an Amazon Aurora PostgreSQL database. The web application will perform primarily read queries against the database.
What should the solutions architect do to ensure that the website can scale with increasing traffic? (Choose two.)
A. Enable auto scaling on the ALB to scale the load balancer horizontally.A company wants to migrate an on-premises data center to AWS. The data canter hosts an SFTP server that stores its data on an NFS-based file system. The server holds 200 GB of data that needs to be transferred. The server must be hosted on an Amazon EC2 instance that uses an Amazon Elastic File System (Amazon EFS) file system
When combination of steps should a solutions architect take to automate this task? (Select TWO )
A. Launch the EC2 instance into the same Avalability Zone as the EFS fie systemA mobile gaming company runs application servers on Amazon EC2 instances. The servers receive updates from players every 15 minutes. The mobile game creates a JSON object of the progress made in the game since the last update, and sends the JSON object to an Application Load Balancer. As the mobile game is played, game updates are being lost. The company wants to create a durable way to get the updates in older.
What should a solutions architect recommend to decouple the system?
A. Use Amazon Kinesis Data Streams to capture the data and store the JSON object in Amazon S3.A company is building a website that relies on reading and writing to an Amazon DynamoDB database. The traffic associated with the website predictably peaks during business hours on weekdays and declines overnight and during weekends. A solutions architect needs to design a cost-effective solution that can handle the load.
What should the solutions architect do to meet these requirements?
A. Enable DynamoDB Accelerator (DAX) to cache the data.A company runs an internal browser-based application The application runs on Amazon EC2 instances behind an Application Load Balancer The instances run in an Amazon EC2 Auto Scaling group across multiple Availability Zones The Auto Scaling group scales up to 20 instances during work hours, but scales down to 2 instances overnight Staff are complaining that the application is very slow when the day begins, although it runs well by mid-morning.
How should the scaling be changed to address the staff complaints and keep costs to a minimum?
A. Implement a scheduled action that sets the desired capacity to 20 shortly before the office opensA company wants to create an application that will transmit protected health information (PHI) to thousands of service consumers in different AWS accounts The application servers will sit in private VPC subnets The routing for the application
must be fault tolerant.
What should be done to meet these requirements?
A. Create a VPC endpoint service and grant permissions to specific service consumers to create a connectionAn online shopping application accesses an Amazon RDS Multi-AZ DB instance. Database performance is slowing down the application. After upgrading to the next-generation instance type, there was no significant performance
improvement.
Analysis shows approximately 700 IOPS are sustained, common queries run for long durations and memory utilization is high.
Which application change should a solutions architect recommend to resolve these issues?
A. Migrate the RDS instance to an Amazon Redshift cluster and enable weekly garbage collectionA company has a custom application running on an Amazon EC2 instance that:
1.
Reads a large amount of data from Amazon S3
2.
Performs a multi-stage analysis.
3.
Writes the results to Amazon DynamoDB.
The application writes a significant number of large, temporary files during the multi-stage analysis. The process performance depends on the temporary storage performance. What would be the fastest storage option for holding the temporary files?
A. Multiple Amazon S3 buckets with Transfer Acceleration for storageA company that hosts its web application on AWS wants to ensure all Amazon EC2 instances. Amazon RDS DB instances and Amazon Redshift clusters are configured with tags. The company wants to minimize the effort of configuring and operating this check. What should a solutions architect do to accomplish this?
A. Use AWS Config rules to define and detect resources that are not property taggedA solution architect at a company is designing the architecture for a two-tiered web application. The web application is composed of an internet facing application load balancer that forwards traffic to an auto scaling group of amazon EC2 instances. The EC2 instances must be able to access a database that runs on Amazon RDS.
The company has requested a defence-in-depth approach to the network layout. The company does not want to rely solely on security groups or network ACLs. Only the minimum resources that are necessary should be routable from the internet.
Which network design should the solutions architect recommend to meet these requirements?
A. Place the ALB, EC2 instances and RDS database in private subnets.Nowadays, the certification exams become more and more important and required by more and more enterprises when applying for a job.
