a) To improve data security
b) To distribute workloads evenly across servers
c) To increase network speed
d) To manage user permissions
Correct Answer: b) To distribute workloads evenly across servers
Explanation: Load balancers enhance resource utilization and ensure high availability by distributing incoming traffic across multiple servers.
Question 08
What is a characteristic of an SSD compared to an HDD?
a) Slower data access
b) Mechanical moving parts
c) Higher data transfer speeds
d) Lower durability
Correct Answer: c) Higher data transfer speeds
Explanation: SSDs use flash memory, resulting in faster data access and transfer speeds compared to traditional HDDs, which rely on spinning disks.
Question 09
What does “data encryption” accomplish?
a) Increases data storage capacity
b) Protects data by transforming it into an unreadable format
c) Enhances data transfer speed
d) Reduces the size of data files
Correct Answer: b) Protects data by transforming it into an unreadable format
Explanation: Data encryption secures sensitive information by converting it into a format that cannot be easily understood without the proper decryption key.
Question 10
What is the main role of a network operating system (NOS)?
a) To provide a user interface
b) To manage network resources and facilitate communication between devices
c) To encrypt network traffic
d) To store data
Correct Answer: b) To manage network resources and facilitate communication between devices
Explanation: NOS is designed to handle network functions, allowing multiple devices to communicate, share resources, and manage user access.
Question 11
What is the primary function of a file share server?
a) To manage databases
b) To provide storage that can be accessed by multiple users
c) To enhance security
d) To monitor network traffic
Correct Answer: b) To provide storage that can be accessed by multiple users
Explanation: A file share server centralizes file storage, enabling users to access and share files across a network efficiently.
Question 12
What is an advantage of using a content delivery network (CDN)?
a) Reduced cost of hosting
b) Improved loading times for users
c) Simplified web management
d) Increased data security
Correct Answer: b) Improved loading times for users
Explanation: CDNs cache content at multiple geographic locations, allowing users to access data from the nearest server and reducing latency.
Question 13
What is the purpose of a Syslog server?
a) To store user data securely

Question 15
What does the term “bandwidth throttling” refer to?
a) Increasing internet speed
b) Reducing data transfer rates for specific users or applications
c) Enhancing data security
d) Managing user permissions
Correct Answer: b) Reducing data transfer rates for specific users or applications
Explanation: Bandwidth throttling intentionally limits the data transfer rates to control network traffic and prioritize certain services or users.
Question 16
What is the role of a proxy server?
a) To provide backup storage
b) To act as an intermediary for requests from clients seeking resources from other servers
c) To enhance data transfer speeds
