An application uses an Amazon SQS queue as a transport mechanism to deliver data to a group of EC2 instances for processing. The application owner wants to add a mechanism to archive the incoming data without modifying application code on the EC2 instances.
How can this application be re-architected to archive the data without modifying the processing instances?
A. Trigger a Lambda function by using Amazon CloudWatch Events to retrieve messages from the SQS queue and archive to Amazon S3.Employees from several companies use an application once a year during a specific 30-day period. The periods are different for each company. Traffic to the application spikes during these 30-day periods. How can the application be designed to handle these traffic spikes?
A. Use an Amazon Route 53 latency routing policy to route traffic to an Amazon EC2 instance with the least lag time.A manufacturing company captures data from machines running at customer sites. Currently, thousands of machines send data every 5 minutes, and this is expected to grow to hundreds of thousands of machines in the near future. The data
is logged with the intent to be analyzed in the future as needed.
What is the SIMPLEST method to store this streaming data at scale?
A. Create an Amazon Kinesis Firehouse delivery stream to store the data in Amazon S3.A data-processing application runs on an i3.large EC2 instance with a single 100 GB EBS gp2 volume. The application stores temporary data in a small database (less than 30 GB) located on the EBS root volume. The application is struggling to process the data fast enough, and a Solutions Architect has determined that the I/O speed of the temporary database is the bottleneck.
What is the MOST cost-efficient way to improve the database response times?
A. Enable EBS optimization on the instance and keep the temporary files on the existing volume.A company is developing a data lake solution in Amazon S3 to analyze large-scale datasets. The solution makes infrequent SQL queries only. In addition, the company wants to minimize infrastructure costs. Which AWS service should be used to meet these requirements?
A. Amazon AthenaA Solutions Architect is designing the storage layer for a production relational database. The database will run on Amazon EC2. The database is accessed by an application that performs intensive reads and writes, so the database requires the LOWEST random I/O latency.
Which data storage method fulfills the above requirements?
A. Store data in a filesystem backed by Amazon Elastic File System (EFS).An application stack includes an Elastic Load Balancer in a public subnet, a fleet of Amazon EC2 instances in an Auto Scaling group, and an Amazon RDS MySQL cluster. Users connect to the application from the Internet. The application servers and database must be secure.
How should a Solutions Architect perform this task?
A. Create a private subnet for the Amazon EC2 instances and a public subnet for the Amazon RDS cluster.A Solutions Architect is creating a multi-tiered architecture for an application that includes a public-facing web tier. Security requirements state that the Amazon EC2 instances running in the application tier must not be accessible directly from
the internet.
What should be done to accomplish this?
A. Create a multi-VPC peering mesh with network access rules limiting communications to specific ports. Implement an internet gateway on each VPC for external connectivity.Which service should an organization use if it requires an easily managed and scalable platform to host its web application running on Nginx?
A. AWS LambdaA credit card processing application, hosted on an on-premises server, needs to communicate directly with a database hosted on an Amazon EC2 instance running in a private subnet of a VPC. Compliance requirements state that end-to-end communication should be encrypted.
Which solution will ensure that this requirement is met?
A. Use HTTPS for traffic over VPC peering between the VPC and the on-premises datacenter.Nowadays, the certification exams become more and more important and required by more and more enterprises when applying for a job.
