Google Google Certifications CLOUD-DIGITAL-LEADER Questions & Answers

• Question 271:

  You are a database manager working for a new product that will need millions of reading and writ-ing from the database, with zero downtime, key-value i.e. NoSQL features, no manual steps should be required to ensure consistency, repair data, synchronize writes and deletes, Which of the follow-ing database you choose?

  A. Cloud SQL

  B. Cloud BigTable

  C. Cloud Spanner

  D. Cloud Firestore

  Correct Answer: B

  Cloud BigTable Key features High throughput at low latency Bigtable is ideal for storing very large amounts of data in a key-value store and supports high read and write throughput at low latency for fast access to large amounts of data. Throughput scales linearly--you can increase QPS (queries per second) by adding Bigtable nodes. Bigtable is built with proven infrastructure that powers Google products used by billions such as Search and Maps. Cluster resizing without downtime Scale seamlessly from thousands to millions of reads/writes per second. Bigtable throughput can be dynamically adjusted by adding or removing cluster nodes without restarting, meaning you can increase the size of a Bigtable cluster for a few hours to handle a large load, then reduce the cluster's size again--all without any downtime. Flexible, automated replication to optimize any workload Write data once and automatically replicate where needed with eventual consistency-giving you control for high availability and isolation of reading and write workloads. No manual steps are needed to ensure consistency, repair data, or synchronize writes and deletes. Benefit from a high availability SLA of 99.999% for instances with multi-cluster routing across 3 or more regions (99.9% for single-cluster instances).

• Question 272:

  Because Cloud Monitoring enables users to monitor the performance of their entire cloud infrastructure.

• Question 273:

  You have a well established development and operations team. Your teams were managing the en-tire software delivery/deployment cycle on-premise. When migrating to the cloud, you want to con-tinue having this approach. Which is the ideal option for you?

  A. PaaS-Platform as a Service

  B. SaaS-Software as a Service

  C. IDaaS-Identity as a Service D. IaaS-Infrastructure as a Service

  Correct Answer: D

  IaaS-you're given virtualized resources like VMs, Storage, Network. It is your responsibility to manage everything beyond that. This would be similar to what the organization had on-premise.

• Question 274:

  You have experimented with Google Cloud using your own credit card and expensed the costs to your company. Your company wants to streamline the billing process and charge the costs of your projects to their monthly invoice. What should you do?

  A. Grant the financial team the IAM role of Billing Account User on the billing ac-count linked to your credit card.

  B. Change the billing account of your projects to the billing account of your company.

  C. Create a ticket with Google Billing Support to ask them to send the invoice to your company.

  D. Set up BigQuery billing export and grant your financial department IAM access to query the data.

  Correct Answer: B

  To change the Cloud Billing account for a project, you need to be able to move a project from one Cloud Billing account to another. To accomplish this task, you need permissions adequate to unlink the project from the existing Cloud Billing account AND to link the project to the target Cloud Billing account. Roles with adequate permissions to perform this task: Project Owner or Project Billing Manager on the project, AND Billing Account Administrator or Billing Account User for the target Cloud Billing account

• Question 276:

  Your customer is moving to Google Cloud. They have many teams, each working on many projects. How should they organize resources?

  A. Let each team have one shared Folder with multiple Projects within it so that there is a separation of concerns.

  B. Let each Project have one Folder so that there is a clear separation of concerns.

  C. Let each team have an Organization so that they can entirely manage themselves with their own identity.

  D. Let each team have one shared Project so that it is easy to manage.

  Correct Answer: A

  The recommended approach is to have folders corresponding to teams/departments and they manage the projects within that.-> Sharing a single project will cause a conflict of resources, billing, concerns, etc.-> One folder per project is unnecessary overuse of abstraction/grouping.-> Teams and projects in a company should ideally be centrally managed in a single Organization.
