What is the most cost-effective solution for ensuring predictable performance between a data center and VPCs in different regions?

Single Choice

A Solutions Architect is designing a network solution for a company that has applications running in a data center in Northern Virginia. The applications in the company s data center require predictable performance to applications running in a virtual private cloud (VPC) located in us-east-1, and a secondary VPC in us-west-2 within the same account. The company data center is collocated in an AWS Direct Connect facility that serves the us-east-1 region. The company has already ordered an AWS Direct Connect connection and a cross-connect has been established.

Which solution will meet the requirements at the LOWEST cost?

Provision a Direct Connect gateway and attach the virtual private gateway (VGW) for the VPC in us-east-1 and the VGW for the VPC in us-west-2. Create a private VIF on the Direct Connect connection and associate it to the Direct Connect gateway.

Create private VIFs on the Direct Connect connection for each of the company s VPCs in the us-east-1 and us-west-2 regions. Configure the company s data center router to connect directly with the VPCs in those regions via the private VIFs.

Deploy a transit VPC solution using Amazon EC2-based router instances in the us-east-1 region. Establish IPsec VPN tunnels between the transit routers and virtual private gateways (VGWs) located in the us-east-1 and us-west-2 regions, which are attached to the company s VPCs in those regions. Create a public VIF on the Direct Connect connection and establish IPsec VPN tunnels over the public VIF between the transit routers and the company s data center router.

Order a second Direct Connect connection to a Direct Connect facility with connectivity to the us-west-2 region. Work with a partner to establish a network extension link over dark fiber from the Direct Connect facility to the company s data center. Establish private VIFs on the Direct Connect connections for each of the company s VPCs in the respective regions. Configure the company s data center router to connect directly with the VPCs in those regions via the private VIFs.

What is the most cost-effective solution for collecting and storing data from 2,000 internet-connected sensors?

Single Choice

A Solutions Architect is designing a system that will collect and store data from 2,000 internet-connected sensors. Each sensor produces 1 KB of data every second. The data must be available for analysis within a few seconds of it being sent to the system and stored for analysis indefinitely.
Which is the MOST cost-effective solution for collecting and storing the data?

Put each record in Amazon Kinesis Data Streams. Use an AWS Lambda function to write each record to an object in Amazon S3 with a prefix that organizes the records by hour and hashes the record s key. Analyze recent data from Kinesis Data Streams and historical data from Amazon S3.

Put each record in Amazon Kinesis Data Streams. Set up Amazon Kinesis Data Firehouse to read records from the stream and group them into objects in Amazon S3. Analyze recent data from Kinesis Data Streams and historical data from Amazon S3.

Put each record into an Amazon DynamoDB table. Analyze the recent data by querying the table. Use an AWS Lambda function connected to a DynamoDB stream to group records together, write them into objects in Amazon S3, and then delete the record from the DynamoDB table. Analyze recent data from the DynamoDB table and historical data from Amazon S3

Put each record into an object in Amazon S3 with a prefix what organizes the records by hour and hashes the record s key. Use S3 lifecycle management to transition objects to S3 infrequent access storage to reduce storage costs. Analyze recent and historical data by accessing the data in Amazon S3

Implementing cost control strategies

What is the most cost-effective storage strategy for a new application that ingests millions of small records per minute and requires low latency retrieval?

Single Choice

A solutions architect is designing the data storage and retrieval architecture for a new application that a company will be launching soon. The application is designed to ingest millions of small records per minute from devices all around the world. Each record is less than 4 KB in size and needs to be stored in a durable location where it can be retrieved with low latency. The data is ephemeral and the company is required to store the data for 120 days only, after which the data can be deleted.

The solutions architect calculates that, during the course of a year, the storage requirements would be about 10-15 TB.

Which storage strategy is the MOST cost-effective and meets the design requirements?

Design the application to store each incoming record as a single .csv file in an Amazon S3 bucket to allow for indexed retrieval. Configure a lifecycle policy to delete data older than 120 days.

Design the application to store each incoming record in an Amazon DynamoDB table properly configured for the scale. Configure the DynamoDB Time to Live (TTL) feature to delete records older than 120 days.

Design the application to store each incoming record in a single table in an Amazon RDS MySQL database. Run a nightly cron job that executes a query to delete any records older than 120 days.

Design the application to batch incoming records before writing them to an Amazon S3 bucket. Update the metadata for the object to contain the list of records in the batch and use the Amazon S3 metadata search feature to retrieve the data. Configure a lifecycle policy to delete the data after 120 days.

What is the most cost-effective, high availability storage solution for a data warehousing application with large data files and metadata?

Single Choice

A Solutions Architect is designing the storage layer for a data warehousing application. The data files are large, but they have statically placed metadata at the beginning of each file that describes the size and placement of the file s index. The data files are read in by a fleet of Amazon EC2 instances that store the index size, index location, and other category information about the data file in a database. That database is used by Amazon EMR to group files together for deeper analysis.

What would be the MOST cost-effective, high availability storage solution for this workflow?

Store the data files in Amazon S3 and use Range GET for each file s metadata, then index the relevant data.

Store the data files in Amazon EFS mounted by the EC2 fleet and EMR nodes.

Store the data files on Amazon EBS volumes and allow the EC2 fleet and EMR to mount and unmount the volumes where they are needed.

Store the content of the data files in Amazon DynamoDB tables with the metadata, index, and data as their own keys.
