An organization has 10,000 devices that generate 10 GB of telemetry data per day, with each record size around 10 KB. Each record has 100 fields, and one field consists of unstructured log data with a "String" data type in the English language. Some fields are required for the real-time dashboard, but all fields must be available for long-term generation.
The organization also has 10 PB of previously cleaned and structured data, partitioned by Date, in a SAN that must be migrated to AWS within one month. Currently, the organization does not have any real-time capabilities in their solution. Because of storage limitations in the on-premises data warehouse, selective data is loaded while generating the long-term trend with ANSI SQL queries through JDBC for visualization. In addition to the one-time data loading, the organization needs a cost-effective and real-time solution.
How can these requirements be met? (Choose two.)

• A.Create a Direct Connect connection between AWS and the on-premises data center and copy the data to Amazon S3 using S3 Acceleration. Use Amazon Athena to query the data.
• B.use AWS IoT to send data from devices to an Amazon SQS queue, create a set of workers in an Auto Scaling group and read records in batch from the queue to process and save the data. Fan out to an Amazon SNS queue attached with an AWS Lambda function to filter the request dataset and save it to Amazon Elasticsearch Service for real-time analytics.
• C.Use AWS IoT to send the data from devices to Amazon Kinesis Data Streams with the IoT rules engine.
  Use one Kinesis Data Firehose stream attached to a Kinesis stream to batch and stream the data partitioned by date. Use another Kinesis Firehose stream attached to the same Kinesis stream to filter out the required fields to ingest into Elasticsearch for real-time analytics.
• D.Use AWS IoT to send the data from devices to Amazon Kinesis Data Streams with the IoT rules engine.
  Use one Kinesis Data Firehose stream attached to a Kinesis stream to stream the data into an Amazon S3 bucket partitioned by date. Attach an AWS Lambda function with the same Kinesis stream to filter out the required fields for ingestion into Amazon DynamoDB for real-time analytics.
• E.use multiple AWS Snowball Edge devices to transfer data to Amazon S3, and use Amazon Athena to query the data.

A __________ is the concept of allowing (or disallowing) an entity such as a user, group, or role some type of access to one or more resources.

• A.AWS Account

• D.permission

Can the string value of 'Key' be prefixed with laws?

• A.No
• B.Yes

A company generates a large number of files each month and needs to use AWS import/export to move these files into Amazon S3 storage. To satisfy the auditors, the company needs to keep a record of which files were imported into Amazon S3.
What is a low-cost way to create a unique log for each import job?

• A.Use the log file checksum in the import/export manifest file to create a log file in Amazon S3 for each import
• B.Use the same log file prefix in the import/export manifest files to create a versioned log file in Amazon S3 for all imports
• C.Use the log file prefix in the import/export manifest file to create a unique log file in Amazon S3 for each import
• D.Use script to iterate over files in Amazon S3 to generate a log after each import/export job

Your customers located around the globe require low-latency access to private video files. Which configuration meets these requirements?

• A.Use Amazon S3 with access control lists
• B.Use Amazon EC2 with provisioned IOPS Amazon EBS volumes
• C.Use Amazon CloudFront with signed URLs
• D.Use Amazon S3 with signed URLs
