An Amazon Redshift Database is encrypted using KMS. A data engineer needs to use the AWS CLI to create a KMS encrypted snapshot of the database in another AWS region. Which three steps should the data engineer take to accomplish this task? (Choose three.)
A. Create a new KMS key in the destination region.A social media customer has data from different data sources including RDS running MySQL, Redshift, and Hive on EMR. To support better analysis, the customer needs to be able to analyze data from different data sources and to combine the results.
What is the most cost-effective solution to meet these requirements?
A. Load all data from a different database/warehouse to S3. Use Redshift COPY command to copy data to Redshift for analysis.You can use _____ and _____ to help secure the instances in your VPC.
A. security groups and multi-factor authenticationYou have a large number of web servers in an Auto Scaling group behind a load balancer. On an hourly basis, you want to filter and process the logs to collect data on unique visitors, and then put that data in a durable data store in order to run reports. Web servers in the Auto Scaling group are constantly launching and terminating based on your scaling policies, but you do not want to lose any of the log data from these servers during a stop/termination initiated by a user or by Auto Scaling.
What two approaches will meet these requirements?
Choose 2 answers
A. Install an Amazon CloudWatch Logs Agent on every web server during the bootstrap process. Create a CloudWatch log group and define metric Filters to create custom metrics that track unique visitors from the streaming web server logs. Create a scheduled task on an Amazon EC2 instance that runs every hour to generate a new report based on the CloudWatch custom metricsA city has been collecting data on its public bicycle share program for the past three years. The 5PB dataset currently resides on Amazon S3. The data contains the following datapoints:
1.
Bicycle origination points
2.
Bicycle destination points
3.
Mileage between the points
4.
Number of bicycle slots available at the station (which is variable based on the station location)
5.
Number of slots available and taken at a given time
The program has received additional funds to increase the number of bicycle stations available. All data is regularly archived to Amazon Glacier.
The new bicycle stations must be located to provide the most riders access to bicycles.
How should this task be performed?
A. Move the data from Amazon S3 into Amazon EBS-backed volumes and use an EC-2 based Hadoop cluster with spot instances to run a Spark job that performs a stochastic gradient descent optimization.Your customers located around the globe require low-latency access to private video files. Which configuration meets these requirements?
A. Use Amazon CloudFront with signed URLsYou are deploying an application to track GPS coordinates of delivery in the United States. Coordinates are transmitted from each delivery truck once every three seconds. You need to design an architecture that will enable realtime processing of these coordinates from multiple consumers.
Which service should you use to implement data ingestion?
A. Amazon KinesisAn enterprise customer is migrating to Redshift and is considering using dense storage nodes in its Redshift cluster. The customer wants to migrate 50 TB of data. The customer's query patterns involve performing many joins with thousands
of rows.
The customer needs to know how many nodes are needed in its target Redshift cluster. The customer has a limited budget and needs to avoid performing tests unless absolutely needed.
Which approach should this customer use?
A. Start with many small nodes.Your company wants to start working with AWS, but has not yet opened an account. With which of the following services should you begin local development?
A. Amazon DynamoDBAn organization is designing an Amazon DynamoDB table for an application that must meet the following requirements:
1.
Item size is 40 KB
2.
Read/write ratio 2000/500 sustained, respectively
3.
Heavily read-oriented and requires low latencies in the order of milliseconds
4.
The application runs on an Amazon EC2 instance
5.
Access to the DynamoDB table must be secure within the VPC
6.
Minimal changes to application code to improve performance using write-through cache Which design options will BEST meet these requirements?
A. Size the DynamoDB table with 10000 RCUs/20000 WCUs, implement the DynamoDB Accelerator (DAX) for read performance, use VPC endpoints for DynamoDB, and implement an IAM role on the EC2 instance to secure DynamoDB access.Nowadays, the certification exams become more and more important and required by more and more enterprises when applying for a job.
