REAL QUESTIONS SOLVED ANSWERS
DETAILED REVIEW GRADED A+
⩥ 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.
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.
,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.
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..
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.
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.
Answer: Answer: D
