Which technique involves dividing a large network into smaller, more manageable segments to improve performance?
-
Load Balancing
-
Network Segmentation
-
Traffic Shaping
-
Quality of Service (QoS)
B
Correct answer
Explanation
Network segmentation involves dividing a network into multiple logical or physical segments. This helps isolate network traffic, improve security, and optimize performance by reducing the number of devices and traffic on each segment.
What is the purpose of traffic shaping in network management?
-
Prioritizing network traffic
-
Reducing network latency
-
Increasing network bandwidth
-
Detecting network security threats
A
Correct answer
Explanation
Traffic shaping is a technique used to manage network traffic by prioritizing certain types of traffic over others. This ensures that critical applications and services receive the necessary bandwidth and resources to maintain optimal performance.
What is the primary goal of network optimization?
-
Minimizing network costs
-
Maximizing network security
-
Improving network performance and efficiency
-
Expanding network coverage
C
Correct answer
Explanation
Network optimization aims to improve the overall performance and efficiency of a network by identifying and resolving bottlenecks, optimizing resource allocation, and implementing best practices to enhance network throughput, latency, and reliability.
What is the primary objective of network slicing in 5G?
-
To improve network performance
-
To reduce network latency
-
To increase network capacity
-
To provide customized network services
D
Correct answer
Explanation
Network slicing allows network operators to create multiple virtual networks on a single physical infrastructure, each with its own unique characteristics and performance requirements.
