Google Google Certifications CLOUD-DIGITAL-LEADER Questions & Answers

• Question 221:

  While on-premise, an enterprise had multiple teams, each with its own analytics data store. Attempts to converge the storage for centralized, company-wide analysis failed because of speed and scaling issues. What would be the preferred destination architecture on Google Cloud?

  A. Migrate to Bigtable which provides high throughput reads and writes.

  B. Migrate to Cloud Spanner as a globally scalable SQL database.

  C. Migrate to BigQuery as a central data warehouse.

  D. Migrate to Cloud SQL which supports multiple databases like MySQL, PostgreSQL, and SQL Server-all of the customer's SQL databases can be accommodated here.

  Correct Answer: C

  BigQuery is the data warehousing option on Google Cloud. Since the source data has already been used for analysis, it should easily fit the BigQuery structure too.

• Question 222:

  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?

  A. Use 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.

  B. Use 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.

  C. Use 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.

  D. Use 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.

  Correct 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 225:

  Considering Google Cloud Storage different Options which of the following is / are correct on the basis of their real world use cases?

  A. Cloud Storage : Images, Large Media, files , backups.

  B. Google Cloud BigTable : AdTech, Financial and IoT Data.

  C. Cloud SQL : User Credentials, customer orders.

  D. All of the Above.

  Correct Answer: D

  Cloud Datastore is the best for semi-structured application data that is used in app engines' applications. Bigtable is best for analytical data with heavy read/write events like AdTech, Financial or IoT data. Cloud Storage is best for structured and unstructured, binary or object data like images, large media files and backups. SQL is best for web frameworks and in existing applications like storing user credentials and customer orders. Cloud Spanner is best for large scale database applications that are larger than two terabytes; for example, for financial trading and e-commerce use cases. As I mentioned at the beginning of the module, depending on your application, you might use one or several of these services to get the job done.

• Question 226:

  What type of cloud computing service provides raw compute, storage, and network, organized in ways that are familiar to physical data centers?

  A. Database as a Service.

  B. Platform as a Service.

  C. Infrastructure as a Service.

  D. Software as a Service.

  Correct Answer: C

  What is Infrastructure as a service :

  IaaS (infrastructure as a service) is a computing model that offers resources on-demand to businesses and individuals via the cloud. IaaS is attractive because acquiring computing resources to run applications or store data the traditional way

  requires time and capital. Enterprises must purchase equipment through procurement processes that can take months. They must invest in physical spaces:

  typically specialized rooms with power and cooling. And after deploying the systems, enterprises need IT, professionals, to manage them. All this is challenging to scale when demand spikes or the business grows. Enterprises risk running out

  of capacity or overbuilding and ending up with infrastructure that suffers from low utilization.

  These challenges are why IaaS use is steadily growing. Learn more about Compute Engine, Cloud Storage, etc.

• Question 227:

  A client is currently running software on their on-premise systems that is bound by a certain type of license. They are allowed to run the software on virtualized machines. However, they cannot run them on virtualized machines that are shared by two different companies, teams, or projects. What option do they have on Google Cloud?

  A. Google Cloud is a public cloud accessed by multiple customers.

  B. Allocate a Bare Metal machine.

  C. Setup exclusive login to the VM with self-generated security keys.

  D. Allocate sole-tenant nodes

  Correct Answer: D

  Sole-tenancy lets you have exclusive access to a sole-tenant node, which is a physical Compute Engine server that is dedicated to hosting only your project's VMs. Use sole-tenant nodes to keep your VMs physically separated from VMs in other projects, or to group your VMs together on the same host hardware. https://cloud.google.com/compute/docs/nodes/sole-tenant-nodes

• Question 228:

  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)

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

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

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

  D. Ask 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.

  Correct Answer: AD

  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 229:

  You are consulting for a client who is migrating to Google Cloud. They presently have a matrix or-ganization. Their IT environments were managed around projects. Each team had multiple projects. All the projects had a flat structure under the company. What would you advise them when plan-ning for the move?

  A. On Google Cloud, create a folder corresponding to each team. Under that, there could be projects or further sub folders as the team decides.

  B. In terms of not disturbing the project developers and testers, advise them that the strategic decision is to retain the structure on Google Cloud also.

  C. Since a Project could spawn other sub-Projects, on Google Cloud it is better to as-sign a folder for each Project.

  D. The flat structure is what is currently used in IT organizations, and this can be used as-is which will provide the best results.

  Correct Answer: A

  Folders for a related group of projects are the recommended approach.-> A flat structure under the organization node is possible on Google Cloud, but it is not recommended. It becomes tougher to manage. -> Projects cannot have sub-projects; there can only be resources within Projects.

• Question 230:

  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

  Correct Answer: D

  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.
