Google Cloud Digital Leader Exam
Prep Guide
Exam Preparation for GCP Digital Leader Certification for NEW to Google Cloud &
Non-technical Professionals
January 2022
Sarah Walker-Leptich | www.walkrinthecloud.com
Note from creator: These notes have been adapted from the GCP Digital Leader Exam Pro course created by Andrew
Brown, as well as my own research and doc files. I highly recommend watching his free training videos, paying for his
practice exams/console demos ($24 USD), and reading through these notes before taking the exam.
This exam prep was specifically designed with the exam guide before January 26 modifications. It still provides an in-
depth and highly sufficient overview of Google Cloud that will prepare you for writing the updated exam.
This is meant to be a community document. As of right now anyone can comment on the Google Doc if they see a
mistake or want to make a correction. Permissions will be given to individuals who request to make edits, please always
respect each other, even if you have different opinions.

Chapter One | Cloud Computing Overview
What is Cloud Computing?
The practice of using a network of remote services hosted on the internet to store, manage and process data
rather than a local server or PC (personal computer).
On-premises Public Cloud
- You purchase and house your own - You rent servers
servers - You rent experts/people
- You have to hire people to manage the - You are only responsible for the
servers configuration and code
- You own the risk - Shared responsibility model

, Dedicated Server (pros/cons)
Google Cloud Digital Leader - Exam Preparation | walkrinthecloud.…
- A physical server wholly utilized by a single customer
- Customers overpay for an underutilized server
- You can’t vertical scale, you need manual migration
- Replacing a server is difficult
- You are limited by your host operating system (OS)
- Multiple apps can result in conflicts in resource sharing
- You have a ‘guarantee’ of security, privacy and full utility of underlying resources (guarantee is only
based on the skills of your IT team)
Virtual Machines (pros/cons)
- Can run multiple VMs (virtual machines) on one machine
- Hypervisor is the software layer that lets you run the VM
- A physical server shared by multiple customers
- Pay for a fraction of the server
- You will overpay for an underutilized VM
- Limited by your guest operating system
- Multiple apps on a single VM can result in conflicts in resource sharing
- Easy to export or import images for migration
- Easy to vertical or horizontal scale
Containers (pros/cons)
- VM runs multiple containers
- You can maximize the utilization of the available capacity which is most cost effective
- Your containers share the same underlying OS so containers are more efficient than multiple
VMs
- Multiple apps can run side by side without being limited to the same operating system
requirements and will not cause conflicts during resource sharing
Functions (pros/cons)
- Are managed VMs running managed containers (known as serverless compute)
- You upload a piece of code, choose the amount of memory and duration
- Only responsible for the code/data
- Very cost effective, only pay for the time code is running, VMs only run when there is code to
be executed
- Cold start (booting up) is a con
Types of Environments
1. On-premises - sometimes called ‘private cloud’
2. Public Cloud - sometimes called ‘cloud native’ (Azure, AWS, Google Cloud, etc)
3. Hybrid - mixture of of both on-premises and public cloud
4. Multi Cloud - mixture of different public clouds, sometimes called ‘cross cloud’
Benefits of Cloud Computing
1. Cost Effective: you pay for what you consume, no upfront cost. On-demand pricing or pay as you go
with thousands of customers sharing the cost of resources.
2. Global: launch workloads anywhere in the world, just choose a region.
3. Secure: Cloud providers take care of the physical security. Cloud services are secure by default or
you have the ability to configure access down to a granular level.
4. Reliable: data backup, disaster recovery, data replication and fault tolerance.
