C842: The Complete -Question
Mastery Questions&Answers Guide
with In-Depth Rationales
Question 1
Which cloud computing characteristic allows customers to manage their
utilization by only paying for the resources they use?
A) Broad network access
B) Rapid elasticity
C) Metered service
D) On-demand self-service
Correct Answer: C) Metered service
Rationale: Metered service (also called measured service) is a fundamental
cloud characteristic where resource usage is monitored, controlled, and
reported, enabling pay-per-use billing models. This allows customers to
optimize costs by only paying for what they consume. Broad network
access refers to availability over the network, rapid elasticity enables
scaling, and on-demand self-service allows users to provision resources
without human interaction .
Question 2
,Which cloud deployment model allows customers to take advantage of
service and price differences from two or more cloud vendors?
A) Public cloud
B) Hybrid cloud
C) Multi-cloud
D) Private cloud
Correct Answer: C) Multi-cloud
Rationale: A multi-cloud strategy involves using services from multiple
cloud providers simultaneously. This approach allows organizations to
leverage competitive pricing, avoid vendor lock-in, and choose best-of-
breed services from different providers. A hybrid cloud combines public
and private cloud, while public and private clouds refer to single-provider
deployment models .
Question 3
What does "operational excellence" focus on in cloud design?
A) Data encryption and access controls
B) Operating highly available workloads
C) Continuous improvement of cloud operations
D) Resource hierarchy organization
Correct Answer: C) Continuous improvement of cloud operations
Rationale: Operational excellence in cloud architecture focuses on
continuous improvement of operational processes, including monitoring,
automation, and refinement of cloud operations. While reliability focuses
on high availability and fault tolerance, operational excellence ensures that
,cloud services are managed efficiently and improved over time through
systematic processes and feedback loops .
Question 4
Which concept focuses on operating highly available workloads in the
cloud?
A) Resource hierarchy
B) Security
C) Reliability
D) Operational excellence
Correct Answer: C) Reliability
Rationale: Reliability in cloud design ensures workloads can recover quickly
from disruptions and continue operating as expected. This concept focuses
on high availability, fault tolerance, and disaster recovery. Reliability
requires implementing redundancy, backup strategies, and robust
monitoring. Security ensures data protection, operational excellence covers
continuous improvement, and resource hierarchy refers to organizational
structures .
Question 5
Which software type allows multiple operating systems to run on the same
physical server in a virtualized environment?
A) Container
B) Hypervisor
C) Quantum computing
D) Blockchain technology
, Correct Answer: B) Hypervisor
Rationale: A hypervisor is the software layer that enables virtualization by
allowing multiple operating systems (guest OS) to run concurrently on a
single physical host. It manages resource allocation and isolation between
virtual machines. Containers, by contrast, share the host OS kernel rather
than running separate operating systems .
Question 6
What is the name of the process of automatically provisioning, configuring,
and managing virtual machines and other resources in a virtualized
environment?
A) Continuous deployment
B) Programmability
C) Orchestration
D) Continuous integration
Correct Answer: C) Orchestration
Rationale: Orchestration refers to the automated management of complex
IT systems and workloads, including provisioning, configuration, and
coordination of virtual machines and other cloud resources. It goes beyond
automation to coordinate multiple automated tasks into a cohesive
workflow. Continuous deployment and integration relate to software
development pipelines, while programmability refers to the ability to
control systems through APIs .
Question 7
Which cloud computing characteristic enables resources to be scaled up or
down quickly based on demand?
