    2.A company is running a batch analysis every hour on their main transactional DB. running on an RDS MySQL instance to populate their central Data Warehouse running on Redshift During the execution of the batch their transactional applications are very slow When the batch completes they need to update the top management dashboard with the new data The dashboard is produced by another system running on-premises that is currently started when a manually-sent email notifies that an update is required The on-premises system cannot be modified because is managed by another team.

    How would you optimize this scenario to solve performance issues and automate the process as much as possible?

    A.Replace RDS with Redshift for the batch analysis and SNS to notify the on-premises system to update the dashboard
     
    B.Replace ROS with Redsnift for the oaten analysis and SQS to send a message to the on-premises system to update the dashboard
     
    C.Create an RDS Read Replica for the batch analysis and SNS to notify me on-premises system to update the dashboard
     
    D.Create an RDS Read Replica for the batch analysis and SQS to send a message to the on-premises system to update the dashboard.
     
     

    C. Create an RDS Read Replica for the batch analysis and SNS to notify me on-premises system to update the dashboard

    3.You are responsible for a legacy web application whose server environment is approaching end of life You would like to migrate this application to AWS as quickly as possible, since the application environment currently has the following limitations:

    ✑ The VM’s single 10GB VMDK is almost full

    ✑ Me virtual network interface still uses the 10Mbps driver, which leaves your 100Mbps WAN connection completely underutilized

    ✑ It is currently running on a highly customized. Windows VM within a VMware environment:

    ✑ You do not have me installation media

    This is a mission critical application with an RTO (Recovery Time Objective) of 8 hours. RPO (Recovery Point Objective) of 1 hour. How could you best migrate this application to AWS while meeting your business continuity requirements?

    A.Use the EC2 VM Import Connector for vCenter to import the VM into EC2.
     
    B.Use Import/Export to import the VM as an ESS snapshot and attach to EC2.
     
    C.Use S3 to create a backup of the VM and restore the data into EC2.
     
    D.Use me ec2-bundle-instance API to Import an Image of the VM into EC2
     
     

    A. Use the EC2 VM Import Connector for vCenter to import the VM into EC2.

    4.Your startup wants to implement an order fulfillment process for selling a personalized gadget that needs an average of 3-4 days to produce with some orders taking up to 6 months you expect 10 orders per day on your first day. 1000 orders per day after 6 months and 10,000 orders after 12 months.

    Orders coming in are checked for consistency men dispatched to your manufacturing plant for production quality control packaging shipment and payment processing If the product does not meet the quality standards at any stage of the process employees may force the process to repeat a step Customers are notified via email about order status and any critical issues with their orders such as payment failure.

    Your case architecture includes AWS Elastic Beanstalk for your website with an RDS MySQL instance for customer data and orders.

    How can you implement the order fulfillment process while making sure that the emails are delivered reliably?

    A.Add a business process management application to your Elastic Beanstalk app servers and re-use the ROS database for tracking order status use one of the Elastic Beanstalk instances to send emails to customers.
     
    B.Use SWF with an Auto Scaling group of activity workers and a decider instance in another Auto Scaling group with min/max=1 Use the decider instance to send emails to customers.
     
    C.Use SWF with an Auto Scaling group of activity workers and a decider instance in another Auto Scaling group with min/max=1 use SES to send emails to customers.
            
    D. Use an SQS queue to manage all process tasks Use an Auto Scaling group of EC2 Instances that poll the tasks and execute them. Use SES to send emails to customers.
     
     

    B. Use SWF with an Auto Scaling group of activity workers and a decider instance in another Auto Scaling group with min/max=1 use SES to send emails to customers

    5.You are the new IT architect in a company that operates a mobile sleep tracking application

    When activated at night, the mobile app is sending collected data points of 1 kilobyte every 5 minutes to your backend

    The backend takes care of authenticating the user and writing the data points into an Amazon DynamoDB table.

    Every morning, you scan the table to extract and aggregate last night’s data on a per user basis, and store the results in Amazon S3.

    Users are notified via Amazon SMS mobile push notifications that new data is available, which is parsed and visualized by (The mobile app Currently you have around 100k users who are mostly based out of North America.


    You have been tasked to optimize the architecture of the backend system to lower cost what would you recommend? (Choose 2 answers)

    A.Create a new Amazon DynamoDB (able each day and drop the one for the previous day after its data is on Amazon S3.
     
    B.Have the mobile app access Amazon DynamoDB directly instead of JSON files stored on Amazon S3.
     
    C.Introduce an Amazon SQS queue to buffer writes to the Amazon DynamoDB table and reduce provisioned write throughput.
     
    D.Introduce Amazon Elasticache lo cache reads from the Amazon DynamoDB table and reduce provisioned read throughput.
     
    E.Write data directly into an Amazon Redshift cluster replacing both Amazon DynamoDB and Amazon S3.
     
     
    • C. Introduce an Amazon SQS queue to buffer writes to the Amazon DynamoDB table and reduce provisioned write throughput. Most Voted
    • D. Introduce Amazon Elasticache to cache reads from the Amazon DynamoDB table and reduce provisioned read throughput.
