• Question 63:

  Your organization is migrating to Google Cloud. As part of that effort, it needs to move terabytes of data from on-premises file servers to Cloud Storage. Your organization wants the migration process to be automated and to be managed by Google. Your organization has an existing Dedicated Interconnect connection that it wants to use. Which Google Cloud product or feature should your organization use?

  A. Storage Transfer Service
  B. Migrate for Anthos
  C. BigQuery Data Transfer Service
  D. Transfer Appliance
  A. Storage Transfer Service

  ---

  Storage Transfer Service is a fully managed service that helps you transfer data from on-premises file servers to Cloud Storage.

• Question 64:

  A retail organization has moved all of their inventory data to a relational database in the cloud. What functionality does a relational database offer?

  A. It analyzes unstructured data which can then be accessed in multiple regions
  B. It stores transactional data which can then be accessed electronically
  C. It stores large amounts of raw data in its original format
  D. It rapidly analyzes large and multi-dimensional datasets
  B. It stores transactional data which can then be accessed electronically

  ---

  Explanation Explanation/Reference:A relational database offers the functionality of storing transactional data, which can then be accessed electronically. Relational databases store structured data that can be organized in tables with defined relationships between them. This makes them well-suited for transactional data, such as inventory data, that needs to be accessed and updated frequently.

• Question 65:

  Your application has repeated data requests of the exact same nature. At the same time, the number of user requests is increasing. Monitoring indicates that the load on the existing database is increasing, and there seems to be a bottleneck. An analysis of the data requested shows us that it is application-managed data and that it changes, but not often. How can you improve the efficiency of the application?

  A. Use Cloud Memorystore to improve speed via caching
  B. Increase the amount of RAM on the machine hosting the database so that it has higher data throughput.
  C. Use Cloud Storage with multi-regional storage so that all users accessing the data will have lower latency
  D. Increase the number of CPUs on the machine hosting the database so that it has higher data throughput.
  A. Use Cloud Memorystore to improve speed via caching

  ---

  Explanation Explanation/Reference:Cloud Memorystore is an in-memory database that has sub-millisecond latency. This is ideal for caching application data that also changes once in a while. https://cloud.google.com/memorystore

• Question 66:

  An organization is evaluating its defenses against cyber security threats and is concerned about the risks of social engineering by cyber criminals. How might these attacks happen?

  A. SQL injection attacks
  B. Physical damage to hardware
  C. Phishing emails
  D. Distributed denial-of-service attacks
  C. Phishing emails

  ---

  Phishing emails are a common form of social engineering attack where attackers impersonate legitimate entities to trick users into revealing sensitive information, such as passwords or credit card details. These attacks exploit human psychology rather than technical vulnerabilities. Phishing emails is correct because it represents a primary method of social engineering used by cybercriminals to manipulate individuals into divulging confidential information.

• Question 67:

  An organization is using machine learning to make predictions. One of their datasets mistakenly includes mislabeled data.

  How will the prediction be impacted?

  A. Increased risk of privacy leaks
  B. Increased risk of inaccuracy
  C. Decreased model compatibility
  D. Decreased model training time
  B. Increased risk of inaccuracy

  ---

  Mislabeled data can introduce errors and inconsistencies into the training process, which can lead to inaccurate predictions. When the model learns from mislabeled examples, it may develop incorrect patterns or associations, compromising its ability to make accurate predictions on new, unseen data.

• Question 68:

  What is the benefit of using a unified cloud data solution?

  A. Data will always cost less to store
  B. Data can be automatically secured from external threats
  C. Data can enable innovation because it's no longer siloed.
  D. Data will always be backed up and cannot be lost or deleted
  C. Data can enable innovation because it's no longer siloed.

• Question 69:

  In terms of Infrastructure as a Service (IaaS) what are the benefits of it?

  A. IaaS offers virtually infinite flexibility and scalability, enterprises can get their work done more efficiently, ensuring faster development life cycles.
  B. IaaS resources are regularly available to businesses when they need them. As a result, enterprises reduce delays when expanding infrastructure and, alternatively, don't waste resources by overbuilding capacity.
  C. IaaS resources are used on demand and enterprises only have to pay for the compute, storage, and networking resources that are actually used, IaaS costs are fairly predictable and can be easily contained and budgeted for.
  D. All of the Above
  D. All of the Above

  ---

  These are the feature of Infrastructure as a Service (IaaS) It's economical Because IaaS resources are used on demand and enterprises only have to pay for the compute, storage, and networking resources that are actually used, IaaS costs are fairly predictable and can be easily contained and budgeted for. It's efficient IaaS resources are regularly available to businesses when they need them. As a result, enterprises reduce delays when expanding infrastructure and, alternatively, don't waste resources by overbuilding capacity. It boosts productivity Because the cloud provider is responsible for setting up and maintaining the underlying physical infrastructure, enterprise IT departments save time and money and can redirect resources to more strategic activities. It's reliable IaaS has no single point of failure. Even if any one component of the hardware resources fails, the service will usually still remain available. It's scalable One of the biggest advantages of IaaS in cloud computing is the capability to scale the resources up and down rapidly according to the needs of the enterprise. It drives faster time to market Because IaaS offers virtually infinite flexibility and scalability, enterprises can get their work done more efficiently, ensuring faster development life cycles.

• Question 70:

  Your application is onboarding a number of users. The details of the users very widely. What kind of database would be most suitable for this use case?

  A. NoSQL database like Firestore
  B. OLAP database like BigQuery which support SQL
  C. SQL database like MySQL or PostgreSQL
  D. OLTP database like Cloud Spanner
  A. NoSQL database like Firestore

  ---

  1.NoSQL databases are best suited for this use case. Firestore is an appropriate one to use here 2.Cloud Firestore is a NoSQL document database that lets you easily store, sync, and query data for your mobile and web apps-at global scale.
