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.
How does chassis aggregation differ from traditional switch stacking?
- Both physical and logical connections
- Logical connection
- No connection
- Physical connection
Chassis aggregation involves both physical and logical connections between switches, whereas traditional switch stacking primarily uses a physical connection.
