Cloud Digital Leader

Certification exam guide

A Cloud Digital Leader can articulate the capabilities of Google Cloud core products and services and how they benefit organizations. The Cloud Digital Leader can also describe common business use cases and how cloud solutions support an enterprise. The Cloud Digital Leader exam is job-role agnostic and does not require hands-on experience with Google Cloud.

The Cloud Digital Leader exam assesses your knowledge in these areas:

  • Section 1: Digital transformation with Google Cloud (~10% of the exam)
  • Section 2: Innovating with data and Google Cloud (~30% of the exam)
  • Section 3: Infrastructure and application modernization (~30% of the exam)
  • Section 4: Google Cloud security and operations (~30% of the exam)

Section 1: Introduction to digital transformation with Google Cloud (approximately 10% of the exam)

This is just 10% of the exam, so, no need to spend too much effort here, just knows the basics and move to the other sections where we actually get 30% relevance.

1.1  Explain why cloud technology is revolutionizing business

Well, cloud is like having unlimited infrastructure over the internet, in multiple regions, with unlimited computing and storage power. Also, cloud is about being scalable, flexible, adaptable, also easier to maintain, no need for upfront costs, pay as you go models, and reliability with all those regions, and dedicated hosts, etc.

    ●  Define key terms such as cloud, cloud technology, data, and digital transformation

Cloud is having computing power and infra available on the internet.

Cloud technology, as my understanding, is what makes the cloud, like, cloud computing technology, cloud storage technology, cloud infra, etc.

Data is what users or external source provides and stores within the cloud.

Digital transformation is the process of using digital technologies to create new — or modify existing — business processes, culture, and customer experiences to meet changing business and market requirements. (source)

1.2 Explain why it is critical for businesses to adopt new technology

Adopting new tech is important for business so they can keep up with customers and clients demands and expectations. Also to be able to compete against the competition, to have technology edger over others, or to try to.

    ●  Compare and contrast cloud technology and traditional or on-premises technology

We already know that cloud is elastic, scalable, reliable, flexible, etc. Whereas, in on-prem network we do can make our network also elastic, scalable, reliable, flexible, but it takes great cost, it’s usually not feasible. Therefore, with on-prem we usually have more customization, specially in the infrastructure part, but with cloud we don’t have much infra customization, as the cloud providers take care of it for us, but we have everything else, like power to use as much as computing power necessary, allocate and de-allocate resources at will, and only pay for what we use.

    ●  Describe how customer expectations have changed because of cloud technology 

Well, I think that now we are more used to always have systems with near 100% uptime, that never slows down because in the background the cloud is taking care of load by decreasing or increasing computing power, or storage, or ram, users are always expecting their apps/systems to behave like that, to have fail safes, to be also be able to recover from disaster, never loose data.

    ●  Identify the business and technical considerations that organizations need to think about when adopting cloud technology, including: infrastructure; application and business platform modernization; the importance of data; security in the cloud

Very broad topic here, but I think they are talking about the shared responsibility model. See the images below.

overview – shared responsibility model for google cloud
compute power – shared responsibility model for google cloud

They might also be talking about Total Cost of Ownership (TCO), and how CAPEX vs OPEX models works. In the cloud you are OPEX, meaning, it’s operational expenses, meaning you are paying for what you are using within the cloud. For CAPEX, you are using money upfront to acquire hardware and software, and to maintain it all, meaning to hire people, pay for power, location, etc.

Sample Questions Answered and Reviewed

Here are some questions I find worth sharing with you.

Question 01

Question here is, what is maturity level to Google Cloud? What is this “transformational one” maturity level?

To be able to answer this question we must know about Google Cloud Adoption Framework (GCAF), it is a guide from Google to help customers with cloud adoption. You can check it in completeness here (it’s a pdf).

There are many topics on GCAF, but for this particular question what we need to understand is this:

GCAF Phases (source)

Google Cloud Adoption Framework also suggests that a businesses readiness for success in the cloud is determined by current business practices in each of these four themes. For each theme, those practices will fall into one of the following phases: 

Tactical (short term goals): Individual workloads are in place, but no coherent plan encompassing all of them with a strategy for building out to the future. The focus is on reducing the cost of discrete systems and on getting to the cloud with minimal disruption. The wins are quick, but there is no provision for scale. 

Strategic (mid term goals): A broader vision governs individual workloads, which are designed and developed with an eye to future needs and scale. You have begun to embrace change, and the people and processes portion of the equation are now involved. IT teams are both efficient and effective, increasing the value of harnessing the cloud for your business operations. 

Transformational (long term goals): With cloud operations functioning smoothly, you’ve turned your attention to integrating the data and insights garnered from working now in the cloud. Existing data is transparently shared. New data is collected and analyzed. The predictive and prescriptive analytics of machine learning applied. Your people and processes are being transformed, which further supports the technological changes. IT is no longer a cost center, but has become instead a partner to the business. 

Question 02

I didn’t really know what was SLO, so here it is Google Cloud definition for SLO with an example: “Latency can exceed 300 ms in only 5 percent of the requests over a rolling 30-day period”. But yeah, lowering SLO (I was trying to think SLO same as SLA) wouldn’t make any good. So this couldn’t be the correct answer.

Move to hybrid also not, because the question says “has completed migrated to the cloud”, why go back to on-prem? Makes no sense, so no.

Modernize their apps, this is the correct one, kind of simple and objective, but way too vague, so I thought, but well, it is what it is.

Manually provision, yeah, this is counter intuitive, we are moving towards the age of fully automatic stuff, so I guess I guessed wrong here.

If you noticed, like I am noticing now, this is that kind of question where you remove all that you know that is wrong and go with the one that can be the answer, even if the correct answer is as vague as it is.

Question 03

Developers want cloud providers to take full control of their apps performance, what, how? Makes no sense.

IT managers want to stop making gradual changes. Well, honestly I thought this could be the answer, but maybe IT managers aren’t the ones doing changes, so I left this one.

IT managers want cloud providers to make infra changes for them. I should kept my thought on IT managers don’t run changes, and left this one, but I didn’t, that’s why I failed.

Developers want to test ideas and experiment with more ease. In the end this is really the one that makes more sense, as in the cloud you can scale in and out, up and down, and also deploy resources quickly and easily.

Question 04

I was like, ok, they have the hardware, they have their cloud, so now use API to integrate that hardware to your cloud, or public cloud. But nope, so API here is actually being used to connect the hardware to their customer service app, whatever it is. The answer reflects my line of thought, but I still picked the wrong answer.

Question 05

Again, same thing here. No sensitive data goes to the public cloud, apparently. But I was more thinking about push notifications, so dashboards and charts wasn’t really looking like a correct answer to me, that’s why I got it wrong.

Question 06

Those questions are so tricky and vague. Ok, you can establish a partnership between sectors, but how does that guarantees that you will lower you cloud costs? Google might have some paper on this, once/if I found it, this will be updated.

Question 07

That’s a good one. I was really like between A and C. I probably already saw that question/answer on some Azure scenario.
