Quality of Service

Answer 13

• Allows Prioritization and management of network traffic based on importance
• Ensures optimal performance for critical applications

Question 14

Network Address Translation

Answer 14

• Translates private IP addresses to a single public IP address for internet communication
• Provides a security layer and conserves public IP addresses
