You are running a data warehouse on BigQuery. A partner company is offering a recommendation engine based on the data in your data warehouse. The partner company is also running their applica-tion on Google Cloud. They manage the resources in their own project, but they need access to the BigQuery dataset in your project. You want to provide the partner company with access to the da-taset. What should you do?
- A. Create a Service Account in your own project, and ask the partner to grant this Service Account access to BigQuery in their project.
- B. Create a Service Account in your own project, and grant this Service Account ac-cess to BigQuery in your project.

質問 # 150
An application has become very popular and the number of requests/users is increasing quickly. There is a meeting to figure out how to scale the systems so that they can accept user requests and still have the capacity to spare. What is the preferred option?
- A. Circular Scaling takes a round-robin approach to allocate and destroy VMs.
- B. Vertical Scaling
- C. Horizontal Scaling
- D. Triangular Scaling takes an automated average of Cost, Effort, and Time.
正解：C

Horizontal scaling, also called scaling out, adds new VMs to increase application capacity.
質問 # 151
A financial services company is running an experimental application workload that has a very large number of mathematical calculations involving floating-point numbers. The current application that is running on compute engine is not providing enough speed and throughput. What are the options to increase the processing performance?
- A. Since processing could also be dependent on reading and writing data to the disk, use a fast Local SSD.
- B. Instead of using a "general purpose" machine family, use "compute-optimized" machine family.
- C. Attach GPUs to the virtual machine for number crunching.
- D. Use a serverless option like Cloud Functions that will automatically scale as much as required.
正解：C
解説：
Compute Engine provides graphics processing units (GPUs) that you can add to your virtual machines (VMs). You can use these GPUs to accelerate specific workloads on your VMs such as machine learning and data processing.

質問 # 153
One of your clients is in the retail sector. They have a small team supporting their operations and a small development team taking care of application development. They have heard of the benefits of machine learning, but they do not have the capacity to hire data scientists or the work to retain them. They have a team of analysts who works primarily on BigQuery and knows how to run SQL queries. They want to be able to get into the new age of machine learning and artificial intelligence. What options are available to run on Google Cloud?
- A. Use BigQuery ML to create machine learning models using SQL queries.
- B. Use the Unified AI Platform to create a custom TensorFlow model.
- C. Integrate the Cloud Vision API and the Cloud Speech API to create a custom mod-el that will suit the retail sector.
- D. Use the popular open-source libraries SciPy and NumPy to create machine learn-ing models.
正解：A
解説：
BigQuery ML allows you to create ML models using standard SQL queries. Those familiar with BigQuery and ML will be able to create ML models with just a basic understanding of machine learning.

質問 # 157
What is a key difference between VMs and containers?
- A. Virtual Machines can only run Linux; containers can run any operating system.
- B. Virtual Machines use a shared operating system and are therefore lighter; containers are heavier on resources.
- C. Virtual Machines take less time to launch; containers take longer to launch.
- D. Each Virtual Machine in a machine has its own operating system; containers will share the same operating system.
正解：D
解説：
VMs have their individual OSs. All containers on a node use the host operating system.
