The company segregates the data by business unit, using specific prefixes. Scientists can only access the data from their own business unit. The company needs a single sign-on identity and management solution based on Microsoft Active Directory (AD) to manage access to the data in Amazon S3 .  \nWhich method meets these requirements?  \nA) Use AWS IAM Federation functions and specify the associated role based on the users' groups in AD.  \nB) Create bucket policies that only allow access to the authorized prefixes based on the users' group name in Active Directory.  \nC) Deploy the AD Synchronization service to create AWS IAM users and groups based on AD information.  \nD) Use Amazon S3 API integration with AD to impersonate the users on access in a transparent manner.  \n2) An administrator has a 500-GB file in Amazon S3 . The administrator runs a nightly COPY command into a 10-node Amazon Redshift cluster. The administrator wants to prepare the data to optimize performance of the COPY command.  \nHow should the administrator prepare the data?  \nA) Compress the file using gz compression.  \nB) Split the file into 500 smaller files.  \nC) Convert the file format to AVRO.  \nD) Split the file into 10 files of equal size.  \n3) A customer needs to load a 550-GB data file into an Amazon Redshift cluster from Amazon S3 , using the COPY command. The input file has both known and unknown issues that will probably cause the load process to fail. The customer needs the most efficient way to detect load errors without performing any cleanup if the load process fails.  \nWhich technique should the customer use?  \nA) Split the input file into 50-GB blocks and load them separately.  \nB) Use COPY with NOLOAD parameter.  \nC) Write a script to delete the data from the tables in case of errors.  \nD) Compress the input file before running COPY.  \n4) An organization needs a data store to handle the following data types and access patterns:  \n􀁸 Key-value access pattern  \n􀁸 Complex SQL queries and transactions  \n􀁸 Consistent reads  \n􀁸 Fixed schema  \nWhich data store should the organization choose?  \nA) Amazon S3  \nB) Amazon Kinesis  \nC) Amazon DynamoDB  \nD) Amazon RDS  \n5) A web application emits multiple types of events to Amazon Kinesis Streams for operational reporting. Critical events must be captured immediately before processing can continue, but informational events do not need to delay processing.  \nWhat is the most appropriate solution to record these different types of events?  \n© 2017, Amazon Web Services, Inc. or its affiliates. All rights [reserved | aws.amazon.com](reserved | aws.amazon.com) 1  \nA) Log all events using the Kinesis Producer Library.  \nB) Log critical events using the Kinesis Producer Library , and log informational events using the PutRecords API method.  \nC) Log critical events using the PutRecords API method , and log informational events using the Kinesis Producer Library.  \nD) Log all events using the PutRecords API method.  \n6) An administrator decides to use the Amazon Machine Learning service to classify social media posts that mention your company into two categories: posts that require a response and posts that do not. The training dataset of 10,000 posts contains the details of each post, including the timestamp, author, and full text of the post. You are missing the target labels that are required for training.  \nWhich two options will create valid target label data?  \nA) Ask the social media handling team to review each post and provide the label.  \nB) Use the sentiment analysis NLP library to determine whether a post requires a response.  \nC) Use the Amazon Mechanical Turk web service to publish Human Intelligence Tasks that ask Turk workers to label the posts.  \nD) Using the a priori probability distribution of the two","cbCaiiZvaGQgNEvs","https://ap.wps.com/l/cbCaiiZvaGQgNEvs","pdf",317176,"English","# Sample Exam Questions\n## Data access and federation\n## Redshift COPY optimization\n## Redshift load error detection\n## Data store selection\n## Kinesis event recording\n## Amazon Machine Learning labels\n## Secure mobile data ingestion\n## Encrypted data collection architecture","[{\"question\":\"Which approach meets the requirement for SSO identity management with Microsoft AD access to S3 data by business-unit prefixes?\",\"answer\":\"Use AWS IAM Federation functions and map roles to the users’ groups in AD (Option A).\"},{\"question\":\"How can a Redshift administrator prepare a 500-GB S3 file to optimize the nightly COPY command?\",\"answer\":\"Convert the file format to AVRO (Option C).\"},{\"question\":\"What technique allows detecting Redshift load errors efficiently without performing cleanup if the load fails?\",\"answer\":\"Use COPY with the NOLOAD parameter (Option B).\"}]","BD-S%20Sample%20Questions%20for%20Web | PDF",1789933577,13]
