Question
Case Study 1 - Flowlogistic Company Background The company started as a regional trucking company, and then expanded into other logistics market. Because they have not updated their infrastructure, managing and tracking orders and shipments has become a bottleneck. To improve operations, Flowlogistic developed proprietary technology for tracking shipments in real time at the parcel level. However, they are unable to deploy it because their technology stack, based on Apache Kafka, cannot support the processing volume. In addition, Flowlogistic wants to further analyze their orders and shipments to determine how best to deploy their resources. Solution Concept Flowlogistic wants to implement two concepts using the cloud: Use their proprietary technology in a real-time inventory-tracking system that indicates the location of their loads Perform analytics on all their orders and shipment logs, which contain both structured and unstructured data, to determine how best to deploy resources, which markets to expand info. They also want to use predictive analytics to learn earlier when a shipment will be delayed. Existing Technical Environment Flowlogistic architecture resides in a single data center: Databases 8 physical servers in 2 clusters - SQL Server - user data, inventory, static data 3 physical servers - Cassandra - metadata, tracking messages 10 Kafka servers - tracking message aggregation and batch insert Application servers - customer front end, middleware for order/customs 60 virtual machines across 20 physical servers - Tomcat - Java services - Nginx - static content - Batch servers Storage appliances - iSCSI for virtual machine (VM) hosts - Fibre Channel storage area network (FC SAN) - SQL server storage - Network-attached storage (NAS) image storage, logs, backups 10 Apache Hadoop /Spark servers - Core Data Lake - Data analysis workloads 20 miscellaneous servers - Jenkins, monitoring, bastion hosts, Business Requirements Build a reliable and reproducible environment with scaled panty of production. Aggregate data in a centralized Data Lake for analysis Use historical data to perform predictive analytics on future shipments Accurately track every shipment worldwide using proprietary technology Improve business agility and speed of innovation through rapid provisioning of new resources Analyze and optimize architecture for performance in the cloud Migrate fully to the cloud if all other requirements are met Technical Requirements Handle both streaming and batch data Migrate existing Hadoop workloads Ensure architecture is scalable and elastic to meet the changing demands of the company. Use managed services whenever possible Encrypt data flight and at rest Connect a VPN between the production data center and cloud environment SEO Statement We have grown so quickly that our inability to upgrade our infrastructure is really hampering further growth and efficiency. We are efficient at moving shipments around the world, but we are inefficient at moving data around. We need to organize our information so we can more easily understand where our customers are and what they are shipping. CTO Statement IT has never been a priority for us, so as our data has grown, we have not invested enough in our technology. I have a good staff to manage IT, but they are so busy managing our infrastructure that I cannot get them to do the things that really matter, such as organizing our data, building the analytics, and figuring out how to implement the CFO' s tracking technology. CFO Statement Part of our competitive advantage is that we penalize ourselves for late shipments and deliveries. Knowing where out shipments are at all times has a direct correlation to our bottom line and profitability. Additionally, I don't want to commit capital to building out a server environment. Flowlogistic's CEO wants to gain rapid insight into their customer base so his sales team can be better informed in the field. This team is not very technical, so they've purchased a visualization tool to simplify the creation of BigQuery reports. However, they've been overwhelmed by all the data in the table, and are spending a lot of money on queries trying to find the data they need. You want to solve their problem in the most cost-effective way. What should you do?
Options
AExport the data into a Google Sheet for virtualization.
BCreate an additional table with only the necessary columns.
CCreate a view on the table to present to the virtualization tool.
DCreate identity and access management (IAM) roles on the appropriate columns, so only they appear in a query.

Explanation
Creating a BigQuery view solves both problems simultaneously: it presents only the relevant columns to the visualization tool (reducing overwhelm) and, because the sales team queries a narrower column set, BigQuery scans less data per query - directly reducing costs, since BigQuery bills by bytes scanned.
Why the distractors fail:
A - Exporting to Google Sheets breaks the live BigQuery integration and requires manual refreshes; it doesn't scale and isn't a sustainable analytics solution.
B - A duplicate table stores redundant data, incurring extra storage costs and requiring ongoing synchronization with the source table - the opposite of cost-effective.
D - BigQuery IAM operates at the dataset/table/row level, not individual columns; column-level security requires policy tags (a separate feature), and even then it restricts access, not what the visualization tool sees by default.
Memory tip: Think "View = Virtual filter" - a view costs nothing to create, stores no extra data, and acts like a custom window into the table. Whenever an exam question asks for a cost-effective way to simplify what users see in BigQuery, a view is almost always the answer.
