Which deployment model uses both a public cloud and a private cloud to cater to different requirements?
Hybrid cloud
Public cloud
Private cloud
Community cloud
Which deployment model provisions cloud infrastructure for a community?

What is an advantage of a public cloud?
You don’t need to invest in hardware or the effort to set up the cloud
You have full control of all computing resources
You avoid internet connectivity and operate offline
You can only run workloads on premises
What is a disadvantage of a public cloud?
You don’t have full control of your computing resources
You must purchase hardware upfront
You cannot scale resources elastically
You must manage all hosting and infrastructure yourself
Which services are provided in Oracle Cloud according to the worksheet? Select all that apply.
Virtual Image
Exudate Cloud Service
Schema as a Service
Tape Backup as a Service
What is an advantage of a private cloud?
You have full control of your resources
No need for any setup effort
Resources are only in the provider’s datacenter
It is always multi‑tenant by default
What is a disadvantage of a private cloud?
The effort needed for private cloud setup
Lack of control over resources
Mandatory multi‑tenant architecture
No ability to run anything on‑premise
Which statement characterizes a hybrid cloud?
Some databases run on‑premise and some are hosted in a public cloud
All workloads must remain on‑premise
Only public cloud resources are used
It eliminates the need for any on‑premise resources
Why is a hybrid cloud considered good for certain situations?
It lets you selectively move some workloads to a public cloud while retaining others on‑premises
It prevents any workload movement between environments
It requires no planning or migration effort
It forces all data into a single tenant environment
In a community cloud, what does “community” refer to according to the worksheet?
Organizations that have shared objectives
A single user’s personal environment
Only government agencies
Unrelated consumers without common goals
In a community cloud, who might manage the cloud?
One or more organizations or a third‑party provider
Only the public cloud provider
Exclusively the end users
Only a single private company with no external involvement
What does metering refer to in the context of cloud computing?
Measurement of resource use
Encrypting data in transit
Provisioning dedicated hardware
Establishing geographic regions
What is chargeback related to in cloud computing?
Charging based on metering of resource use
Selecting data encryption algorithms
Ensuring multi‑tenant isolation
Choosing deployment regions
Where are metering and chargeback always present and where are they optional?
Always present in public clouds; optional in private clouds
Always present in private clouds; optional in public clouds
Optional in both public and private clouds
Not applicable to cloud computing
Which chargeback mode is described as pay‑as‑you‑go with no upfront payment?
Metered
Non‑metered
Reserved
Fixed‑term
Which chargeback mode uses monthly pricing where per‑hour pricing is not applicable?
Non‑metered
Metered
Spot
Prepaid
Which options are provided by Oracle Cloud for database security (database layer)? Select all that apply.
Transparent Data Encryptions (TDE)
SQL*Net Encryptions
Metering
Chargeback
Which statement about geographical presence is given in the worksheet?
Cloud vendors do not have a presence in all geographies
Cloud vendors operate in every country without exceptions
Geographical presence is irrelevant to cloud services
Cloud providers only serve single cities
What does the worksheet state about CAPEX in cloud computing?
No investment is required for setting up the infrastructure
Large upfront investment is always required
Monthly pricing is mandatory
CAPEX increases due to pay‑as‑you‑go
What does the worksheet state about OPEX in cloud computing?
Lower OPEX due to the pay‑as‑you‑go model
Higher OPEX due to fixed monthly pricing
OPEX is unrelated to cloud usage
OPEX only applies to on‑premise systems
What does the worksheet state about provisioning in cloud computing?
Faster provisioning makes cloud computing an ideal platform for test and development environments
Provisioning is slow and unsuitable for testing
Provisioning requires manual hardware setup
Provisioning cannot be automated
What is the cloud computing model as?
Pay-as-you-go model
Pay your invoice after one month
