A company hosts an application on AWS Lambda functions that are invoked by an Amazon API Gateway API. The Lambda functions save customer data to an Amazon Aurora MySQL database. Whenever the company upgrades the
database, the Lambda functions fail to establish database connections until the upgrade is complete. The result is that customer data is not recorded for some of the event.
A solutions architect needs to design a solution that stores customer data that is created during database upgrades.
Which solution will meet these requirements?
A. Provision an Amazon RDS proxy to sit between the Lambda functions and the database. Configure the Lambda functions to connect to the RDS proxy.A company needs the ability to analyze the log files of its proprietary application The logs are stored in JSON format in an Amazon S3 bucket Queries will be simple and will run on- demand A solutions architect needs to perform the analysis with minimal changes to the existing architecture
What should the solutions architect do to meet these requirements with the LEAST amount of operational overhead?
A. Use Amazon Redshift to load all the content into one place and run the SQL queries as neededA company's facility has badge readers at every entrance throughout the building. When badges are scanned, the readers send a message over HTTPS to indicate who attempted to access that particular entrance. A solutions architect must design a system to process these messages from the sensors. The solution must be highly available, and the results must be made available for the company's security team to analyze. Which system architecture should the solutions architect recommend?
A. Launch an Amazon EC2 instance to serve as the HTTPS endpoint and to process the messages Configure the EC2 instance to save the results to an Amazon S3 bucket.A solutions architect is designing a customer-facing application. The application is expected to have a variable amount of reads and writes depending on the time of year and clearly defined access patterns throughout the year. Management
requires that database auditing and scaling be managed in the AWS Cloud. The Recovery Point Objective (RPO) must be less than 5 hours.
Which solutions can accomplish this? (Select TWO.)
A. Use Amazon DynamoDB with auto scaling. Use on-demand backups and AWS CloudTrail.A company is developing a new machine learning (ML) model solution on AWS. The models are developed as independent microservices that fetch approximately 1GB of model data from Amazon S3 at startup and load the data into memory Users access the models through an asynchronous API Users can send a request or a batch of requests and specify where the results should be sent
The company provides models to hundreds of users. The usage patterns for the models are irregular. Some models could be unused for days or weeks Other models could receive batches of thousands of requests at a time
Which design should a solutions architect recommend to meet these requirements?
A. Direct the requests from the API to a Network Load Balancer (NLB) Deploy the models as AWS Lambda functions that are invoked by the NLB.A company with facilities in North America Europe, and Asia is designing new distributed application to optimize its global supply chain and manufacturing process. The orders booked on one continent should be visible to all Regions in a second or less. The database should be able to support failover with a short Recovery Time Objective (RTO) The uptime of the application is important to ensure that manufacturing is not impacted What should a solutions architect recommend?
A. Use Amazon DynamoDB global tablesA company is building a new dynamic ordering website. The company wants to minimize server maintenance and patching. The website must be highly available and must scale read and write capacity as quickly as possible to meet changes in user demand.
A. Host static content in Amazon S3. Host dynamic content by using Amazon API Gateway and AWS Lambda. Use Amazon DynamoDB with on-demand capacity for the database Configure Amazon CloudFront to deliver the website content.A business application is hosted on Amazon EC2 and uses Amazon S3 for encrypted object storage. The chief information security officer has directed that no application traffic between the two services should traverse the public internet. Which capability should the solutions architect use to meet the compliance requirements?
A. AWS Key Management Service (AWS KMS) )A company has a web application for travel ticketing. The application is based on a database that runs in a single data center in North America The company wants to expand the application to serve a global user base. The company needs to display the application to multiple AWS Regions. Average latency must be less than 1 second on updates to reservation database.
The company wants to have separate deployments of its web platform across multiple Regions.
However, the company must maintain a single primary reservation database that is globally consistent.
Which solution should a solutions architect recommend to meet these requirements?
A. Convert the application to use Amazon DynamoDB. Use a global table for the center reservation table. Use the correct Regional endpoint in each Regional deployment.Cost Explorer is showing charges higher than expected for Amazon Elastic Block Store (Amazon EBS) volumes connected to application servers in a production account A significant portion of the changes from Amazon EBS are from volumes that were created as Provisioned IOPS SSD (io1) volume types Controlling costs is the highest priority for this application Which steps should the user take to analyze and reduce the EBS costs without incurring any application downtime'? (Select TWO )
A. Use the Amazon EC2 ModifylnstanceAttribute action to enable EBS optimization on the application server instancesNowadays, the certification exams become more and more important and required by more and more enterprises when applying for a job.
