CLOUD ESSENTIALS CLO-002 EXAM
2025 QUESTIONS AND ANSWERS
Type 1 hypervisor - ANS Also known as a bare metal
Sits on the hardware
Acts as OS
Faster than Type 2
Type 2 Hypervisor - ANS Sits on top of the OS
Commonly used in client side virtualization
Ex: User running windows and linux on same PC
Kernel-based Virtual Machine - ANS Open source virtualization software included in Linux
Infracstructure as a Service (IaaS) - ANS The CSP provides hardware infrastructure. This often
means compute, storage, and network capabilities.
Platform as a Service (PaaS) - ANS Adds features to IaaS that include OSs and software
development tools such as runtime environments. The vendor manages the various hardware
platforms, freeing up the software developer to focus on building their application and scaling
it.
Software as a Service (SaaS) - ANS Delivers applications over the cloud using a pay-per-use
revenue model

,Elastic - ANS meaning the cloud can grow or shrink as the client's needs change made
possible by resource pooling
Self Service - ANS This characteristic allows users to access additional resources (such as
storage, network, or compute) automatically, 24 hours a day, 7 days a week, 365 days a year,
without requiring intervention from the service provider.
Scalability - ANS The ability to use more or fewer resources is called
Broad Network Access - ANS Applies to clients using different OSs, such as Windows, macOS,
Linux, iOS, or Android
Availability - ANS Means that cloud resources are accessible and responsive whenever a
client needs them.
Shared responsibility model - ANS Customer: responsible for security "in" the cloud
Provider responsible for security "of" the cloud
Recovery point objective (RPO) - ANS How old can restored data be and still be useful to use
to run the business?
Recovery Time Objective (RTO) - ANS It defines how long the CSP has to get everything
operational, including network access and data restoration
Areas that should be covered in redundancy plans - ANS Process
Software
Network

, Public Cloud Pros/Cons - ANS The client does not need to invest in hardware that will go
obsolete in a few years, but downsides can be a lack of control and security.
Private Cloud Pros/Cons - ANS Allow the company to retain security and resource control but
usually cost more because of the hardware replacement life cycle.
Hybrid Cloud Pros/Cons - ANS Hybrid clouds are the best and worst of both worlds because
they combine features of public and private clouds.
Six Characteristics of clouds - ANS Pay as you go
Availability
Scalability
Elasticity
Self-Service
Broad Network Access
The cloud security model is called - ANS Shared Responsibility Model
software-defined networking (SDN) - ANS using a central control program separate from
network devices to manage the flow of data on a network. SDN allows apps to communicate
with it and then passes the traffic to the respective network equipment.
Load Balancing - ANS Distributing a computing or networking workload across multiple
systems to avoid congestion and slow performance. (Ex: Amazon web servers receive request
from load balancers to distribute shopper requests on their site)
Load Balancing Benefits - ANS Performance
Scalability
Reliability
