Google Cloud Digital Leader Practice Test - Questions Answers, Page 22

The key reason I included this question is to clarify some terminologies that will be important for your estimates. The data size mentioned is a TB terabyte. Note the "byte". The speed is mentioned in Mbps, which is Megabits per second.

Note the "bits". 8 bits make a byte. So, to get the actual number of bits transferred, you need to multiply the TB number by 8.

Total data transferred (in bits) = 100 * 1,000,000,000,000 * 8 bits

Speed = 100Mbps = 100 * 1,000,000. i.e. 100 million bits are transferred per second.

Hence time taken to transfer all the data = Total Data/Speed = 8,000,000 seconds.

Number of seconds in a day = 24*60*60 = 86,400

Total time taken in days = 8,000,000/86,400 = 92.59 days

Spanner is a global scale Database that Support SQL querying, Similar to PostgreSQL, Which will be regional. So that will be a fairly smooth move, Since they have the time and the funding, they can plan for this migration.

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.

Compliance Reports Manager, GDPR Home Page, Compliance Offerings

GCP provides three main compliance resource webpages

Compliance Reports Manager ñ https://cloud.google.com/security/compliance/compliance-reports-manager

Compliance Offerings ñ https://cloud.google.com/security/compliance/offerings

GDPR Resource Center ñ https://cloud.google.com/security/gdpr/resource-center

At Google Cloud, we champion initiatives that prioritize and improve the security and privacy ofcustomer personal data, and want you, as a Google Cloud customer, to feel confident using ourservices in light of GDPR requirements. If you partner with Google Cloud, we will support your GDPRcompliance efforts

Community Cloud ñ The cloud infrastructure is planned for selective use by a particular community of consumers from organizations that have mutual interests like security needs, policy, and compliance considerations.

Google Cloud Pub/Sub is a scalable, durable event ingestion and delivery system.

-> Pub/Sub allows services to communicate asynchronously, with latencies on the order of 100 milliseconds.

-> Pub/Sub is used for streaming analytics and data integration pipelines to ingest and distribute data. It is equally effective as messaging-oriented middleware for service integration or as a queue to parallelize tasks.

-> Pub/Sub enables you to create systems of event producers and consumers, called publishers and subscribers. Publishers communicate with subscribers asynchronously by broadcasting events, rather than by synchronous remote procedure calls (RPCs).

Local SSDs are attached to the VM and have very high throughput. However, when the VM shuts down, The local SSD is also shut down, Since our Workload here is foult tolerant, than is not an issue.

Sustained, Committed and Preemptible vCPU and memory usage for each of these categories can receive discounts VM vCPU and memory usage for each of these categories can receive discounts Sustained-use discountsóGoogle offers up to 30% off for workloads that run for most of the billing month on GCP services.

Committed-use discountsóusers can save up to 57% by committing to use an instance for a certain time period, with no upfront payment and with the flexibility to change instances during the commitment period.

Preemptible VMsósimilar to the concept of AWS spot instances, Google offers up to 79% off for Virtual Machines that may be shut down at any time and replaced by others.
