failure of one or more components.
Question 02
What is the primary function of a hypervisor in a cloud environment?
a) To create and manage virtual machines
b) To store encrypted data
c) To act as a firewall
d) To manage network traffic
Correct Answer: a) To create and manage virtual machines
Explanation: A hypervisor manages the resources of a physical server to create and run
multiple virtual machines.
Question 03
What type of backup captures only the changes made since the last full backup?
a) Full backup
b) Incremental backup
c) Differential backup
d) Snapshot
Correct Answer: b) Incremental backup
Explanation: An incremental backup saves only the data that has changed since the last
full backup, reducing storage space.
Question 04
Which protocol is commonly used for secure file transfers over the network?
a) HTTP
b) FTP
c) SFTP
d) Telnet
Correct Answer: c) SFTP
Explanation: SFTP is a secure version of FTP that encrypts file transfers using SSH.
Question 05
What happens during an RTO (Recovery Time Objective)?
a) The time taken to recover lost data
b) The maximum allowable downtime before services must be restored
c) The cost associated with disaster recovery
d) The speed at which backups are performed
Correct Answer: b) The maximum allowable downtime before services must be restored
Explanation: RTO defines the amount of time within which a business process must be
restored after a disruption.
Question 06
What is a key advantage of a hybrid cloud?
a) Unlimited data storage
b) Combination of private and public cloud resources
c) Lower security risk
d) Cost-free infrastructure
Correct Answer: b) Combination of private and public cloud resources
Explanation: A hybrid cloud allows organizations to combine private and public cloud
environments for flexibility and scalability.
Question 07
In virtualization, what does CPU affinity refer to?
a) Assigning a virtual CPU to a specific physical CPU core
b) Allocating storage to a virtual machine
c) Scheduling virtual CPUs based on priority
d) Enabling dynamic memory allocation
Correct Answer: a) Assigning a virtual CPU to a specific physical CPU core
Explanation: CPU affinity ensures that a virtual machine's processing thread is assigned
to a specific physical CPU core.
Question 08
What is the purpose of storage virtualization?
a) To encrypt data in storage
b) To create a storage pool that can be shared across virtual machines
c) To provide unlimited storage to users
d) To manage security policies in the cloud
Correct Answer: b) To create a storage pool that can be shared across virtual machines
Explanation: Storage virtualization combines multiple storage devices into a virtual pool
that can be allocated to different virtual machines.
Question 09
What is the most efficient way to ensure that network traffic is evenly distributed across
multiple servers?
a) Using a firewall
b) Implementing load balancing
c) Increasing CPU cores
d) Configuring disk partitions
Correct Answer: b) Implementing load balancing
Explanation: Load balancing distributes network traffic across multiple servers to
optimize performance and prevent overloading.
Question 10
What is the primary reason for implementing a hot site as part of a disaster recovery
plan?
a) To reduce power consumption
b) To provide an off-site location for backup storage
c) To ensure rapid recovery with minimal downtime
d) To reduce software licensing costs
Correct Answer: c) To ensure rapid recovery with minimal downtime
Explanation: A hot site is a fully operational backup site that can take over quickly in
case of a disaster, minimizing downtime.
Question 11
What is the purpose of using RAID (Redundant Array of Independent Disks)?
a) To increase network speed
b) To provide fault tolerance and improve data redundancy
c) To enhance cloud security
d) To speed up CPU processing
Correct Answer: b) To provide fault tolerance and improve data redundancy
Explanation: RAID is used to distribute data across multiple disks to prevent data loss
and improve performance.
Question 12
What technology allows users to access their virtual desktops from any device over the
internet?
a) Virtualization
b) Thin client technology
c) Desktop as a Service (DaaS)
d) Cloud storage
Correct Answer: c) Desktop as a Service (DaaS)
Explanation: DaaS delivers a virtual desktop to users over the internet, allowing them to
access it from any device.
Question 13
Which cloud service model provides a complete development environment for
application developers?
a) IaaS
b) PaaS
c) SaaS
d) DaaS
Correct Answer: b) PaaS
Explanation: Platform as a Service (PaaS) provides developers with the tools and
environment to develop, test, and deploy applications.
Question 14
What is the role of a hypervisor in managing virtual machines?
a) Encrypting data
b) Monitoring network traffic
c) Allocating hardware resources to virtual machines
d) Preventing unauthorized access
Correct Answer: c) Allocating hardware resources to virtual machines
Explanation: A hypervisor manages the physical hardware and allocates resources to
virtual machines running on a server.
Question 15
What is the purpose of elastic scaling in cloud computing?
a) To improve security
b) To reduce latency
c) To dynamically allocate resources based on demand
d) To encrypt data in transit
Correct Answer: c) To dynamically allocate resources based on demand
Explanation: Elastic scaling allows cloud services to automatically adjust resources in
response to changing demand.
Question 16
What does CPU overcommitment mean in virtualization?
a) Assigning more virtual CPUs than are physically available on the host
b) Reducing CPU usage
c) Allocating physical CPUs to a single virtual machine
d) Preventing virtual machines from using CPU resources
Correct Answer: a) Assigning more virtual CPUs than are physically available on the host
Explanation: CPU overcommitment allows more virtual CPUs to be allocated than there
are physical CPUs available, relying on efficient CPU scheduling.
Question 17
What type of cloud service model is primarily used for hosting applications and
databases?
a) IaaS
b) PaaS
c) SaaS
d) DaaS
Correct Answer: c) SaaS
Explanation: SaaS allows users to access applications and databases over the internet
without managing the underlying infrastructure.
Question 18
In cloud computing, what is resource pooling?
a) Encrypting data across multiple locations
b) Sharing physical resources among multiple customers
c) Backing up data to multiple storage devices
d) Segmenting network traffic
Correct Answer: b) Sharing physical resources among multiple customers
Explanation: Resource pooling enables a cloud provider to serve multiple customers
using shared resources such as storage, processing power, and network bandwidth.
