What is the primary function of a firewall in a network security infrastructure?
- Protect against unauthorized access
- Speed up network traffic
- Manage IP addresses
- Monitor server performance
The primary function of a firewall is to protect against unauthorized access by controlling incoming and outgoing network traffic.
Which routing method requires manual configuration of routing entries by network administrators?
- Default Routing
- Dynamic Routing
- Hybrid Routing
- Static Routing
Static routing requires manual configuration of routing entries by network administrators.
What role does packet classification play in Quality of Service (QoS)?
- Identifying and marking packets
- Filtering out unwanted packets
- Encrypting sensitive packets
- Fragmenting large packets
Packet classification in QoS involves identifying and marking packets to facilitate proper prioritization and treatment.
A network designer is selecting cable types for a new corporate office. The requirement is for a reliable, high-speed network that supports data, voice, and video transmission. Which cable type should be prioritized?
- Cat 5e
- Cat 6
- Coaxial
- Fiber Optic
Fiber optic cables are known for their high-speed transmission and reliability, making them suitable for supporting data, voice, and video in a corporate office.

In the context of routing, what does the term 'redistribution' refer to?
- Encrypting routing information
- Load balancing traffic
- Prioritizing certain routes
- Sharing routes between different routing protocols
Redistribution in routing refers to the process of sharing routes between different routing protocols, allowing them to exchange routing information.
