a) To allocate memory
b) To manage virtual machines on a host
c) To encrypt virtual data
d) To distribute network traffic
Correct Answer: b) To manage virtual machines on a host
Explanation: A hypervisor enables the creation and management of multiple virtual
machines on a single physical server.
Question 07
What type of cloud storage is best suited for storing large amounts of unstructured data
like images and videos?
a) Block storage
b) Object storage
c) File system storage
d) RAM
Correct Answer: b) Object storage
Explanation: Object storage is designed for large, unstructured data such as images,
videos, and backups.
Question 08
What is the key advantage of using containers in cloud environments?
a) They provide high security
b) They offer better isolation than virtual machines
c) They improve application density
d) They require less memory than VMs
Correct Answer: c) They improve application density
Explanation: Containers allow multiple applications to run on the same system,
improving resource utilization and application density.
Question 09
What is the purpose of multi-factor authentication (MFA) in cloud environments?
a) To simplify login processes
b) To increase the speed of authentication
c) To enhance security by requiring multiple forms of verification
d) To allocate resources more efficiently
Correct Answer: c) To enhance security by requiring multiple forms of verification
Explanation: MFA improves security by requiring users to provide additional verification
factors beyond just a password.
Question 10
In which cloud service model does the provider manage both the hardware and software
for applications?
a) IaaS
b) SaaS
c) PaaS
d) DaaS
Correct Answer: b) SaaS
Explanation: Software as a Service (SaaS) provides both the application and the
underlying infrastructure, managed by the provider.
Question 11
What cloud deployment model combines both private and public cloud environments?
a) Community cloud
b) Hybrid cloud
c) Private cloud
d) Public cloud
Correct Answer: b) Hybrid cloud
Explanation: A hybrid cloud uses a mix of private and public cloud environments to
provide flexibility and scalability.
Question 12
What is a key benefit of using RAID in cloud environments?
a) Increased data redundancy and performance
b) Improved internet speeds
c) Higher encryption standards
d) Faster access to virtual machines
Correct Answer: a) Increased data redundancy and performance
Explanation: RAID improves data redundancy and read/write performance by
distributing data across multiple disks.
Question 13
What is the primary use of block storage in cloud environments?
a) To store files and documents
b) To host virtual machine disks and databases
c) To manage network bandwidth
d) To encrypt data
Correct Answer: b) To host virtual machine disks and databases
Explanation: Block storage is ideal for virtual machine disk storage, databases, and
transactional data.
Question 14
What is the purpose of a hot site in disaster recovery planning?
a) To increase CPU performance
b) To provide immediate backup and failover capabilities
c) To store encrypted data
d) To reduce internet traffic
Correct Answer: b) To provide immediate backup and failover capabilities
Explanation: A hot site is a fully operational backup facility that can take over operations
immediately during a disaster.
Question 15
What is a common reason for using role-based access control (RBAC) in cloud
environments?
a) To encrypt data
b) To assign permissions based on user roles
c) To manage network traffic
d) To allocate storage efficiently
Correct Answer: b) To assign permissions based on user roles
Explanation: RBAC allows administrators to assign permissions to users based on their
specific roles within an organization.
Question 16
What is the key function of a Content Delivery Network (CDN) in cloud environments?
a) To encrypt data in transit
b) To distribute content to users from the nearest server
c) To store virtual machine backups
d) To monitor network traffic
Correct Answer: b) To distribute content to users from the nearest server
Explanation: CDNs reduce latency by delivering content from servers geographically
closer to the user.
Question 17
What is the purpose of synchronous replication in cloud storage?
a) To encrypt data during transmission
b) To ensure real-time consistency across multiple storage locations
c) To monitor network performance
d) To reduce storage costs
Correct Answer: b) To ensure real-time consistency across multiple storage locations
