Question 08
What is a key feature of server virtualization?
a) It enhances physical security
b) It allows multiple virtual servers to run on a single physical server
c) It simplifies user management
d) It increases storage capacity
Correct Answer: b) It allows multiple virtual servers to run on a single physical server
Explanation: Server virtualization maximizes resource utilization and flexibility by enabling multiple virtual servers to operate independently on one physical machine.
Question 09
What does the term “phishing” refer to in cybersecurity?
a) Unauthorized access to a system
b) A method of tricking individuals into providing sensitive information
c) The installation of malware
d) Network performance monitoring
Correct Answer: b) A method of tricking individuals into providing sensitive information
Explanation: Phishing attacks typically involve deceptive emails or websites that lure users into revealing personal information, such as passwords or credit card numbers.
Question 10
What is the primary purpose of network segmentation?
a) To increase internet speed
b) To improve security and performance by isolating different segments of a network
c) To simplify data management
d) To reduce hardware costs
Correct Answer: b) To improve security and performance by isolating different segments of a network
Explanation: Network segmentation enhances security by limiting access to sensitive data and reducing traffic congestion, allowing for better performance.
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
b) To collect and store system messages from networked devices
c) To manage user permissions
d) To encrypt data
Correct Answer: b) To collect and store system messages from networked devices
Explanation: Syslog servers gather logs and system messages from various network devices, aiding in monitoring and troubleshooting.
Question 14
What is the function of network monitoring tools?
a) To secure data
b) To monitor and analyze network performance and security
c) To manage user permissions
d) To provide internet access

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
d) To manage user authentication
Correct Answer: b) To act as an intermediary for requests from clients seeking resources from other servers
