Question 126

Business owners at your company have given you a database of bank transactions. Each row contains the user ID, transaction type, transaction location, and transaction amount. They ask you to investigate what type of machine learning can be applied to the data. Which three machine learning applications can you use? (Choose three.)

    Flowlogistic Case Study
    Company Overview
    Flowlogistic is a leading logistics and supply chain provider. They help businesses throughout the world manage their resources and transport them to their final destination. The company has grown rapidly, expanding their offerings to include rail, truck, aircraft, and oceanic shipping.
    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 wants to use Google BigQuery as their primary analysis system, but they still have Apache Hadoop and Spark workloads that they cannot move to BigQuery. Flowlogistic does not know how to store the data that is common to both workloads. What should they do?
  • Question 128

    You are deploying a new storage system for your mobile application, which is a media streaming service. You decide the best fit is Google Cloud Datastore. You have entities with multiple properties, some of which can take on multiple values. For example, in the entity 'Movie' the property 'actors' and the property 'tags' have multiple values but the property 'date released' does not. A typical query would ask for all movies with actor=<actorname> ordered by date_released or all movies with tag=Comedy ordered by date_released. How should you avoid a combinatorial explosion in the number of indexes?

  • Question 129

    You decided to use Cloud Datastore to ingest vehicle telemetry data in real time. You want to build a storage system that will account for the long-term data growth, while keeping the costs low. You also want to create snapshots of the data periodically, so that you can make a point-in-time (PIT) recovery, or clone a copy of the data for Cloud Datastore in a different environment. You want to archive these snapshots for a long time. Which two methods can accomplish this? (Choose two.)
  • Question 130

    You work for a shipping company that uses handheld scanners to read shipping labels. Your company has strict data privacy standards that require scanners to only transmit recipients' personally identifiable information (PII) to analytics systems, which violates user privacy rules. You want to quickly build a scalable solution using cloud-native managed services to prevent exposure of PII to the analytics systems. What should you do?
