EXPLANATION
Answer: X - EXPLANATION Content.
Question1: Your company is running their first dynamic campaign, serving different offers by analyzing real-time data during the holiday season. The data scientists are collecting terabytes of data that rapidly grows every hour during their 30-day campaign. They are using Google Cloud Dataflow to preprocess the data and collect the feature (signals) data that is needed for the machine learning model in Google Cloud Bigtable. The team is observing suboptimal performance with reads and writes of their initial load of 10 TB of data. They want to improve this performance while minimizing cost. What should they do?
Question2: 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_releasedor all movies with tag=Comedyordered by date_released. How should you avoid a combinatorial explosion in the number of indexes?C: Set the following in your entity options: exclude_from_indexes = 'actors, tags' D: Set the following in your entity options: exclude_from_indexes = 'date_published'
Question3: You are building a model to predict whether or not it will rain on a given day. You have thousands of input features and want to see if you can improve training speed by removing some features while having a minimum effect on model accuracy. What can you do?
Question4: Flowlogistic Case StudyCompany OverviewFlowlogistic 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 BackgroundThe 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 ConceptFlowlogistic wants to implement two concepts using the cloud:Use their proprietary technology in a real-time inventory-tracking system that indicates the location oftheir loadsPerform analytics on all their orders and shipment logs, which contain both structured and unstructureddata, 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 EnvironmentFlowlogistic architecture resides in a single data center:Databases8 physical servers in 2 clusters- SQL Server - user data, inventory, static data3 physical servers- Cassandra - metadata, tracking messages10 Kafka servers - tracking message aggregation and batch insertApplication servers - customer front end, middleware for order/customs60 virtual machines across 20 physical servers- Tomcat - Java services- Nginx - static content- Batch serversStorage appliances- iSCSI for virtual machine (VM) hosts- Fibre Channel storage area network (FC SAN) - SQL server storage- Network-attached storage (NAS) image storage, logs, backupsApache Hadoop /Spark servers- Core Data Lake- Data analysis workloads20 miscellaneous servers- Jenkins, monitoring, bastion hosts,Business RequirementsBuild a reliable and reproducible environment with scaled panty of production.Aggregate data in a centralized Data Lake for analysisUse historical data to perform predictive analytics on future shipmentsAccurately track every shipment worldwide using proprietary technologyImprove business agility and speed of innovation through rapid provisioning of new resourcesAnalyze and optimize architecture for performance in the cloudMigrate fully to the cloud if all other requirements are metTechnical RequirementsHandle both streaming and batch dataMigrate existing Hadoop workloadsEnsure architecture is scalable and elastic to meet the changing demands of the company.Use managed services whenever possibleEncrypt data flight and at restConnect a VPN between the production data center and cloud environmentSEO StatementWe 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 StatementIT 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 StatementPart 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 management has determined that the current Apache Kafka servers cannot handle the data volume for their real-time inventory tracking system. You need to build a new system on Google Cloud Platform (GCP) that will feed the proprietary tracking software. The system must be able to ingest data from a variety of global sources, process and query in real-time, and store the data reliably. Which combination of GCP products should you choose?
Question5: Your company uses a proprietary system to send inventory data every 6 hours to a data ingestion service in the cloud. Transmitted data includes a payload of several fields and the timestamp of the transmission. If there are any concerns about a transmission, the system re-transmits the data. How should you deduplicate the data most efficiency?
Question6: Your company is loading comma-separated values (CSV) files into Google BigQuery. The data is fully imported successfully; however, the imported data is not matching byte-to-byte to the source file. What is the most likely cause of this problem?
Question7: MJTelco Case StudyCompany OverviewMJTelco is a startup that plans to build networks in rapidly growing, underserved markets around the world. The company has patents for innovative optical communications hardware. Based on these patents, they can create many reliable, high-speed backbone links with inexpensive hardware.Company BackgroundFounded by experienced telecom executives, MJTelco uses technologies originally developed to overcome communications challenges in space. Fundamental to their operation, they need to create a distributed data infrastructure that drives real-time analysis and incorporates machine learning to continuously optimize their topologies. Because their hardware is inexpensive, they plan to overdeploy the network allowing them to account for the impact of dynamic regional politics on location availability and cost.Their management and operations teams are situated all around the globe creating many-to-many relationship between data consumers and provides in their system. After careful consideration, they decided public cloud is the perfect environment to support their needs.Solution ConceptMJTelco is running a successful proof-of-concept (PoC) project in its labs. They have two primary needs:Scale and harden their PoC to support significantly more data flows generated when they ramp to morethan 50,000 installations.Refine their machine-learning cycles to verify and improve the dynamic models they use to controltopology definition.MJTelco will also use three separate operating environments - development/test, staging, and production- to meet the needs of running experiments, deploying new features, and serving production customers.Business RequirementsScale up their production environment with minimal cost, instantiating resources when and whereneeded in an unpredictable, distributed telecom user community.Ensure security of their proprietary data to protect their leading-edge machine learning and analysis.Provide reliable and timely access to data for analysis from distributed research workersMaintain isolated environments that support rapid iteration of their machine-learning models withoutaffecting their customers.Technical RequirementsEnsure secure and efficient transport and storage of telemetry dataRapidly scale instances to support between 10,000 and 100,000 data providers with multiple flowseach.Allow analysis and presentation against data tables tracking up to 2 years of data storing approximately100m records/daySupport rapid iteration of monitoring infrastructure focused on awareness of data pipeline problemsboth in telemetry flows and in production learning cycles.CEO StatementOur business model relies on our patents, analytics and dynamic machine learning. Our inexpensive hardware is organized to be highly reliable, which gives us cost advantages. We need to quickly stabilize our large distributed data pipelines to meet our reliability and capacity commitments.CTO StatementOur public cloud services must operate as advertised. We need resources that scale and keep our data secure. We also need environments in which our data scientists can carefully study and quickly adapt our models. Because we rely on automation to process our data, we also need our development and test environments to work as we iterate.CFO StatementThe project is too large for us to maintain the hardware and software required for the data and analysis.Also, we cannot afford to staff an operations team to monitor so many data feeds, so we will rely on automation and infrastructure. Google Cloud's machine learning will allow our quantitative researchers to work on our high-value problems instead of problems with our data pipelines.You need to compose visualizations for operations teams with the following requirements:The report must include telemetry data from all 50,000 installations for the most resent 6 weeks(sampling once every minute).The report must not be more than 3 hours delayed from live data.The actionable report should only show suboptimal links.Most suboptimal links should be sorted to the top.Suboptimal links can be grouped and filtered by regional geography.User response time to load the report must be <5 seconds.Which approach meets the requirements?
Question8: You have spent a few days loading data from comma-separated values (CSV) files into the Google BigQuery table CLICK_STREAM. The column DTstores the epoch time of click events. For convenience, you chose a simple schema where every field is treated as the STRINGtype. Now, you want to compute web session durations of users who visit your site, and you want to change its data type to the TIMESTAMP. You want to minimize the migration effort without making future queries computationally expensive. What should you do?
Question9: You want to use Google Stackdriver Logging to monitor Google BigQuery usage. You need an instant notification to be sent to your monitoring tool when new data is appended to a certain table using an insert job, but you do not want to receive notifications for other tables. What should you do?
Question10: You work for a large fast food restaurant chain with over 400,000 employees. You store employee information in Google BigQuery in a Userstable consisting of a FirstNamefield and a LastNamefield. A member of IT is building an application and asks you to modify the schema and data in BigQuery so the application can query a FullNamefield consisting of the value of the FirstNamefield concatenated with a space, followed by the value of the LastNamefield for each employee. How can you make that data available while minimizing cost?
Question11: Your company is migrating their 30-node Apache Hadoop cluster to the cloud. They want to re-use Hadoop jobs they have already created and minimize the management of the cluster as much as possible.They also want to be able to persist data beyond the life of the cluster. What should you do?
Question12: You work for a manufacturing plant that batches application log files together into a single log file once a day at 2:00 AM. You have written a Google Cloud Dataflow job to process that log file. You need to make sure the log file in processed once per day as inexpensively as possible. What should you do?
Question13: You are designing the database schema for a machine learning-based food ordering service that will predict what users want to eat. Here is some of the information you need to store:The user profile: What the user likes and doesn't like to eatThe user account information: Name, address, preferred meal timesThe order information: When orders are made, from where, to whomThe database will be used to store all the transactional data of the product. You want to optimize the data schema. Which Google Cloud Platform product should you use?
Question14: Your company's on-premises Apache Hadoop servers are approaching end-of-life, and IT has decided to migrate the cluster to Google Cloud Dataproc. A like-for-like migration of the cluster would require 50 TB of Google Persistent Disk per node. The CIO is concerned about the cost of using that much block storage.You want to minimize the storage cost of the migration. What should you do?
Question15: Your company has hired a new data scientist who wants to perform complicated analyses across very large datasets stored in Google Cloud Storage and in a Cassandra cluster on Google Compute Engine.The scientist primarily wants to create labelled data sets for machine learning projects, along with some visualization tasks. She reports that her laptop is not powerful enough to perform her tasks and it is slowing her down. You want to help her perform her tasks. What should you do?
Question16: You are working on a sensitive project involving private user data. You have set up a project on Google Cloud Platform to house your work internally. An external consultant is going to assist with coding a complex transformation in a Google Cloud Dataflow pipeline for your project. How should you maintain users' privacy?
Question17: You work for an economic consulting firm that helps companies identify economic trends as they happen.As part of your analysis, you use Google BigQuery to correlate customer data with the average prices of the 100 most common goods sold, including bread, gasoline, milk, and others. The average prices of these goods are updated every 30 minutes. You want to make sure this data stays up to date so you can combine it with other data in BigQuery as cheaply as possible. What should you do?

Flowlogistic does not know how to store the data that is common to both workloads. What should they do?
Question23: Your company produces 20,000 files every hour. Each data file is formatted as a comma separated values (CSV) file that is less than 4 KB. All files must be ingested on Google Cloud Platform before they can be processed. Your company site has a 200 ms latency to Google Cloud, and your Internet connection bandwidth is limited as 50 Mbps. You currently deploy a secure FTP (SFTP) server on a virtual machine in Google Compute Engine as the data ingestion point. A local SFTP client runs on a dedicated machine to transmit the CSV files as is. The goal is to make reports with data from the previous day available to the executives by 10:00 a.m. each day. This design is barely able to keep up with the current volume, even though the bandwidth utilization is rather low.You are told that due to seasonality, your company expects the number of files to double for the next three months. Which two actions should you take? (choose two.)
Question24: You are deploying 10,000 new Internet of Things devices to collect temperature data in your warehouses globally. You need to process, store and analyze these very large datasets in real time. What should you do?
Question25: Your company has recently grown rapidly and now ingesting data at a significantly higher rate than it was previously. You manage the daily batch MapReduce analytics jobs in Apache Hadoop. However, the recent increase in data has meant the batch jobs are falling behind. You were asked to recommend ways the development team could increase the responsiveness of the analytics without increasing costs. What should you recommend they do?
