A company wants to research user turnover by analyzing the past 3 months of user activities. With millions of users, 1.5 TB of uncompressed data is generated each day. A 30-node Amazon Redshift cluster with 2.56 TB of solid state drive (SSD) storage for each node is required to meet the query performance goals. The company wants to run an additional analysis on a year’s worth of historical data to examine trends indicating which features are most popular. This analysis will be done once a week. What is the MOST cost-effective solution?
A bank is building an Amazon S3 data lake. The bank wants a single data repository for customer data needs, such as personalized recommendations. The bank needs to use Amazon Kinesis Data Firehose to ingest customers' personal information, bank accounts, and transactions in near real time from a transactional relational database. All personally identifiable information (Pll) that is stored in the S3 bucket must be masked. The bank has enabled versioning for the S3 bucket. Which solution will meet these requirements?
A company uses Amazon Redshift as its data warehouse. A new table has columns that contain sensitive data. The data in the table will eventually be referenced by several existing queries that run many times a day. A data analyst needs to load 100 billion rows of data into the new table. Before doing so, the data analyst must ensure that only members of the auditing group can read the columns containing sensitive data. How can the data analyst meet these requirements with the lowest maintenance overhead?
A company is building a data lake and needs to ingest data from a relational database that has time-series data. The company wants to use managed services to accomplish this. The process needs to be scheduled daily and bring incremental data only from the source into Amazon S3. What is the MOST cost-effective approach to meet these requirements?
A data engineer is using AWS Glue ETL jobs to process data at frequent intervals. The processed data is then copied into Amazon S3. The ETL jobs run every 15 minutes. The AWS Glue Data Catalog partitions need to be updated automatically after the completion of each job. Which solution will meet these requirements MOST cost-effectively?
A company wants to optimize the cost of its data and analytics platform. The company is ingesting a number of .csv and JSON files in Amazon S3 from various data sources. Incoming data is expected to be 50 GB each day. The company is using Amazon Athena to query the raw data in Amazon S3 directly. Most queries aggregate data from the past 12 months, and data that is older than 5 years is infrequently queried. The typical query scans about 500 MB of data and is expected to return results in less than 1 minute. The raw data must be retained indefinitely for compliance requirements. Which solution meets the company’s requirements?
A company wants to use a data lake that is hosted on Amazon S3 to provide analytics services for historical data. The data lake consists of 800 tables but is expected to grow to thousands of tables. More than 50 departments use the tables, and each department has hundreds of users. Different departments need access to specific tables and columns. Which solution will meet these requirements with the LEAST operational overhead?
A manufacturing company has been collecting IoT sensor data from devices on its factory floor for a year and is storing the data in Amazon Redshift for daily analysis. A data analyst has determined that, at an expected ingestion rate of about 2 TB per day, the cluster will be undersized in less than 4 months. A long-term solution is needed. The data analyst has indicated that most queries only reference the most recent 13 months of data, yet there are also quarterly reports that need to query all the data generated from the past 7 years. The chief technology officer (CTO) is concerned about the costs, administrative effort, and performance of a long-term solution. Which solution should the data analyst use to meet these requirements?
A company uses Amazon Redshift for its data warehouse. The company is running an ET L process that receives data in data parts from five third-party providers. The data parts contain independent records that are related to one specific job. The company receives the data parts at various times throughout each day. A data analytics specialist must implement a solution that loads the data into Amazon Redshift only after the company receives all five data parts. Which solution will meet these requirements?
A company needs to implement a near-real-time messaging system for hotel inventory. The messages are collected from 1,000 data sources and contain hotel inventory data. The data is then processed and distributed to 20 HTTP endpoint destinations. The range of data size for messages is 2-500 KB. The messages must be delivered to each destination in order. The performance of a single destination HTTP endpointshould not impact the performance of the delivery for other destinations. Which solution meets these requirements with the LOWEST latency from message ingestion to delivery?

Question 198 - DAS-C01 discussion

Export

A manufacturing company is storing data from its operational systems in Amazon S3. The company's business analysts need to perform one-time queries of the data in Amazon S3 with Amazon Athena. The company needs to access the Athena service from the on-premises network by using a JDBC connection. The company has created a VPC. Security policies mandate that requests to AWS services cannot traverse the internet.

Which combination of steps should a data analytics specialist take to meet these requirements? (Select TWO.)

A.
Establish an AWS Direct Connect connection between the on-premises network and the VPC.
Answers
A.
Establish an AWS Direct Connect connection between the on-premises network and the VPC.
B.
Configure the JDBC connection to connect to Athena through Amazon API Gateway.
Answers
B.
Configure the JDBC connection to connect to Athena through Amazon API Gateway.
C.
Configure the JDBC connection to use a gateway VPC endpoint for Amazon S3.
Answers
C.
Configure the JDBC connection to use a gateway VPC endpoint for Amazon S3.
D.
Configure the JDBC connection to use an interface VPC endpoint for Athena.
Answers
D.
Configure the JDBC connection to use an interface VPC endpoint for Athena.
E.
Deploy Athena within a private subnet.
Answers
E.
Deploy Athena within a private subnet.
Suggested answer: A, D

Explanation:

AWS Direct Connect is a service that establishes a dedicated network connection between your on-premises network and AWS1.It can help you reduce network costs, increase bandwidth throughput, and provide a more consistent network experience than internet-based connections1. It can also help you meet the security policy that requires requests to AWS services not to traverse the internet.

An interface VPC endpoint is a type of VPC endpoint that enables you to privately connect your VPC to supported AWS services and VPC endpoint services powered by AWS PrivateLink2.It is represented by one or more Elastic Network Interfaces (ENIs) with private IP addresses in your VPC subnets2. It can also help you meet the security policy that requires requests to AWS services not to traverse the internet.

Amazon Athena now provides an interface VPC endpoint that allows you to connect directly to Athena through an interface VPC endpoint in your VPC3.You can create an interface VPC endpoint to connect to Athena using the AWS console or AWS CLI commands4.You can also configure the JDBC connection to use the interface VPC endpoint for Athena by specifying the endpoint URL as the JDBC URL5.
