Question 41
What is the purpose of thin provisioning in cloud storage?
a) To allocate storage only when needed
b) To encrypt data stored in the cloud
c) To increase storage capacity
d) To manage network bandwidth
Correct Answer: a) To allocate storage only when needed
Explanation: Thin provisioning allocates storage space to users only when it's actually
needed, helping optimize storage utilization.
Question 42
What is the primary advantage of using object storage in the cloud?
a) Data encryption
b) Scalability and storage of unstructured data
c) Improved CPU performance
d) Higher internet speeds
Correct Answer: b) Scalability and storage of unstructured data
Explanation: Object storage allows scalable storage of large, unstructured data such as
videos, backups, and images.
Question 43
What is the role of DNS in cloud services?
a) To encrypt cloud traffic
b) To map domain names to IP addresses
c) To manage virtual machine storage
d) To monitor cloud performance
Correct Answer: b) To map domain names to IP addresses
Explanation: The Domain Name System (DNS) translates domain names into IP
addresses, allowing users to access cloud resources via human-readable names.
Question 44
What type of access control is used to manage access to files based on the identity of
users or groups?
a) Discretionary Access Control (DAC)
b) Mandatory Access Control (MAC)
c) Role-based Access Control (RBAC)
d) Token-based access
Correct Answer: a) Discretionary Access Control (DAC)
Explanation: DAC allows resource owners to determine who can access files based on
their identity or group memberships.
Question 45
What solution should be used to increase application density in a virtualized
environment?
a) Vertical scaling
b) Containers
c) CPU affinity
d) Memory ballooning
Correct Answer: b) Containers
Explanation: Containers increase application density by allowing multiple applications to
run on a single virtual machine while isolating them from each other.
Question 46
What happens during a disaster recovery failover in a cloud environment?
a) Data is encrypted
b) Resources are reallocated automatically
c) Operations switch from the primary site to a backup site
d) Applications are scaled horizontally
Correct Answer: c) Operations switch from the primary site to a backup site
Explanation: A failover occurs when operations are transferred to a backup site during a
disaster to ensure business continuity.
Question 47
What is the main purpose of using load balancing in cloud computing?
a) To monitor traffic
b) To distribute network traffic across multiple servers
c) To encrypt data
d) To store backups
Correct Answer: b) To distribute network traffic across multiple servers
Explanation: Load balancing ensures that network traffic is evenly distributed across
servers, preventing overload and improving performance.
Question 48
What feature of virtualization allows multiple virtual machines to share a single
physical server?
a) CPU affinity
b) Elasticity
c) Hypervisor
d) RAID
Correct Answer: c) Hypervisor
Explanation: A hypervisor manages virtual machines, allowing them to share the physical
resources of a single server.
Question 49
What is the benefit of using a hot site in disaster recovery planning?
a) Reduced storage costs
b) Immediate availability during a disaster
c) Increased security
d) Faster data encryption
Correct Answer: b) Immediate availability during a disaster
Explanation: A hot site is fully operational and can take over immediately in the event of
a disaster, minimizing downtime.
Question 50
What is the primary purpose of backup and recovery solutions in the cloud?
a) To increase CPU performance
b) To prevent data loss during failures or disasters
c) To monitor network traffic
d) To encrypt all data
Correct Answer: b) To prevent data loss during failures or disasters
Explanation: Backup and recovery solutions ensure that data can be restored in case of
failure or disaster, protecting against data loss.
