OCI Foundations Certification QUESTIONS AND
ANSWERS| DISTICTION
Which of the following is not a core characteristic of cloud computing as defined by NIST
standards?
A. On-demand self-service access
B. Upfront license payments
C. Rapid elasticity
D. Measured services Correct Answer: Answer: B
A, C, D are characteristics as defined by NIST; cloud computing enables pay-as-you-pricing and
does not involve paying for licenses upfront.
Which statement below is NOT correct regarding a highly available system?
A. Highly available systems always involve manual intervention to maintain high availability.
B. Highly available systems typically have redundant hardware and software
C. Highly availability systems avoid having single points-of-failure
D. Highly available systems involve a failover process that moves processing performed by the
failed component to the backup component Correct Answer: Answer: A
It is possible to have some manual intervention, but typically, highly available systems do not
involve manual failover processes. The more transparent the failover is, the more highly
available the system is.
What does compute vertical scaling imply?
A. Compute scaling out is called vertical scaling
B. Compute scaling in is called vertical scaling
C. Compute scaling up (or down) is called vertical scaling
D. In cloud, you can cannot scale compute instances Correct Answer: Answer: C
Scale in or out is horizontal scaling.
Which one of the following is not a cloud pricing model?
A. Pay-as-you-go
B. Commitment based pricing
C. Consumption based pricing
D. Enterprise license based pricing Correct Answer: Answer: D
Enterprise license based pricing is not a cloud pricing model, while the others are. In cloud
computing, you only pay for resources that you use and in some cases, pay only for how much
you consume.
Which statement below is NOT true regarding an Oracle Cloud Infrastructure Region?
A. Each region has at least one Availability Domain.
B. Availability domains are isolated from each other and very unlikely to fail simultaneously.
C. Each Fault Domain has multiple Availability Domains.
D. Each Availability Domain has three Fault Domains. Correct Answer: Answer: C
Each Availability Domain has three Fault Domains and not the other way around.
, Which two are valid reasons to use an Oracle Cloud Infrastructure Fault Domain?
A. Protect against unexpected hardware or power supply failures
B. Protect against planned hardware maintenance
C. To mitigate the risk of large scale events such as earthquakes
D. Build replicated systems for disaster recovery
E. To meet requirements for legal jurisdictions Correct Answer: Answer: A, B
You can use fault domains to (1) protect against unexpected hardware failures or power supply
failures (2) protect against planned outages because of compute hardware maintenance.
Which statement below is NOT true regarding Oracle Cloud Infrastructure High Availability
Architecture?
A. Fault Domains provide protection against failures within an Availability Domain
B. In a multi-AD region, Availability Domain provides protection from an entire Availability
Domain failure
C. OCI region pair enables disaster recovery while meeting compliance and data residency
requirements
D. Compartments enable a high availability design within an Availability Domain Correct
Answer: Answer: D
A compartment is a collection of related resources and provides logical not physical isolation.
Which two are valid reasons to deploy your apps in multiple Oracle Cloud Infrastructure
regions?
A. To mitigate the risk of region-wide events such as large weather systems or earthquakes
B. To achieve high availability and real time data synchronization
C. To meet varying requirements for legal jurisdictions, tax domains, and other business or social
criteria
D. To lower costs, as some OCI regions have lower pricing than others Correct Answer:
Answer: A, C
In OCI, pricing is not region-specific. In addition, if you deploy apps to multiple regions, you
cannot achieve real-time data synchronization as regions can be separated by vast distances—
across countries or even continents
You have two web servers and a clustered database running in a single OCI Availability Domain.
Which step below can help you achieve high availability?
A. Group one web server and one database node in one fault domain and the other half of each
pair in another fault domain
B. OCI provides high availability by default, so you don't need to do anything
C. Put both web servers in the same fault domain and database nodes in another fault domain
D. Put both database nodes in the same fault domain and web servers in another fault domain
Correct Answer: Answer: A
Grouping web server and a database node and placing a pair in two separate fault domains ensure
that a failure of any one fault domain does not result in an outage for your application.
How do instances in Private Subnets in OCI Virtual Cloud Network communicate to Internet?
A. Through a Service Gateway
