APersistent Disk

BCloud SQL.

CCloud Bigtable

DCloud Spanner

EAll of the Above

Answer : E

Question 2

A manufacturing organization has a large collection of images labeled as intact or defective parts. They want to use this data to build a simple solution to detect faulty parts on their production line. They have no data science expertise. Which solution should they use?

ADiscovery Al for Retail

BPre-trainedAPIs

CDocument Al

DAutoML

Answer : D

The correct answer is D. AutoML. Here's why:

Context of the Questio n : The organization wants to build a solution to detect faulty parts on a production line using a large collection of labeled images (intact or defective parts). They do not have data science expertise, so they need a tool that simplifies the machine learning process.

Google Cloud Product Relevance:

AutoML is a suite of machine learning products that allows users to build custom models easily without needing deep expertise in machine learning or data science. It is designed to simplify the process of training, evaluating, and deploying models, especially in cases like image recognition where labeled datasets are already available.

AutoML Vision, a part of AutoML, would be ideal for this use case as it specifically handles image classification and can easily differentiate between intact and defective parts.

Why Not Other Options:

A . Discovery AI for Retail: This is a solution tailored for retail use cases like product discovery and search optimization, not for manufacturing defect detection.

B . Pre-trained APIs: While pre-trained APIs (like Vision API) can recognize general image patterns, they may not be specific enough for a custom use case like detecting defective parts.

C . Document AI: This service is designed for understanding and processing documents, not for analyzing images.

Google Cloud Digital Leader Reference:

Question 3

You're negotiating SLAs with a customer. You have communicated that there will be a 99.99% (four 9s) availability for the service you are providing. Every aspect of the service is under your con-trol. They want to modify the reliability to 99.999% (five 9s). What do you tell them? (Choose two answer)

AYes, that could be possible. If yes, there will be a significantly higher charge be-cause the effort is significantly higher too.

BYes, that is possible, but there will be an additional charge of 9% for the service because that is the additional effort required.

CYes, that is possible. There is hardly any difference to provide another 0.009% availability.

DAsk them for the reasonable downtime they are willing to absorb. If it is more than 60 minutes in an entire year, explain how the current SLA meets that requirement.

Answer : A, D

In many cases, customers might not know the implications of the 9s with respect to scheduled maintenance, upgrades, etc. It's possible that they are holding unnecessary expectations that significantly exceed their requirements.

->Even though 0.0009 % increase it looks like a small increment, an addition of a single 9 reduces the possible downtime by 10 times. So the effort is often much greater.

Question 4

A customer deploys an application to App Engine and needs to check for Open Web Appli-cation Security Project (OWASP) vulnerabilities. Which service should be used to accom-plish this?

ACloud Armor

BCloud Security Scanner

CBinary Authorization

DForseti Security

Answer : B

Web Security Scanner identifies security vulnerabilities in your App Engine, Google Kubernetes Engine (GKE), and Compute Engine web applications. It crawls your application, following all links within the scope of your starting URLs, and attempts to exercise as many user inputs and event handlers as possible.

Currently, Web Security Scanner only supports public URLs and IPs that aren't behind a firewall. Web Security Scanner currently supports the App Engine standard environment and App Engine flexible environments, Compute Engine instances, and GKE resources.

Question 5

An organization stores its important industry data in a relational database They want to create a new revenue stream by enabling third parties to use that data in their applications Which cloud first approach should the organization choose?

AOffer chargeable downloads of archived data.

BTransfer data into a non-relational database

CAdd third-party users to their database

DExpose data through a chargeable API

Answer : D

Question 6

The government has mandated that companies in a particular section of healthcare must retain all the data they collect for a period of 10 years in case an audit needs to be done. Your client, who is in that industry, needs to follow regulations. In addition, your client wants to do an analysis of the data quite frequently in the first year. They also don't want to be liable for any data beyond year 10. What would recommend for your customer?

AUse Cloud Storage with nearline storage in year one and Coldline storage thereaf-ter. Use Object lifecycle management to move between storage types and delete them after 10 years.

BUse Cloud Storage with standard storage in year one and Coldline storage there-after. Set a Cloud Scheduler trigger for 1 year to change storage types and 10 years to delete the data.

CUse Cloud Storage with standard storage in year one and archival storage thereaf-ter. Use Object lifecycle management to move between storage types and delete them after 10 years.

DUse Cloud Storage with standard storage in year one and Coldline storage there-after. Set a Cloud Tasks to trigger for 1 year to change storage types and 10 years to delete the data.

Answer : C

Cloud storage supports Object Lifecycle Management. To support common use cases like setting a Time to Live (TTL) for objects, retaining noncurrent versions of objects, or 'downgrading' storage classes of objects to help manage costs, Cloud Storage offers the Object Lifecycle Management feature.

Standard storage is recommended for frequently accessed data and Archive for data accessed less than once a year.

Nearline, Coldline, and Archive offer ultra-low-cost, highly-durable, highly available archival storage. For data accessed less than once a year, Archive is a cost-effective storage option for the long-term preservation of data. Coldline is also ideal for cold storage---data your business expects to touch less than once a quarter. For warmer storage, choose Nearline: data you expect to access less than once a month, but possibly multiple times throughout the year.

Question 7

Your client is building a custom machine learning pipeline to identify lesions in the lungs based on x-rays. Different teams of data scientists are sharing common source data and building many ver-sions of ML models. Which of these Cloud Storage options would be best for them?

ARetain the data in use in a single region bucket with nearline storage. Retain the data in use in a dual-region bucket.

BRetain the data in use in a single region bucket with standard storage.

CRetain the data in use in a multi-region bucket.

DRetain the data in use in a dual-region bucket.

Answer : B

Integrated repository for analytics and ML: The highest level of availability and performance within a single region is ideal for compute, analytics, and machine learning workloads in a particular region. Cloud Storage is also strongly consistent, giving you confidence and accuracy in analytics workloads.
