A network engineer needs to design a network that can efficiently handle varying types of traffic, such as voice, video, and data. What technology would be most suitable for such requirements?
- QoS (Quality of Service)
- VLAN (Virtual Local Area Network)
- MPLS
- Frame Relay
QoS (Quality of Service) technology is most suitable for designing a network that can efficiently handle varying types of traffic, ensuring the prioritization of voice, video, and data.
For a small network with a stable topology, which routing method is generally more cost-effective and simpler to manage?
- Default Routing
- Dynamic Routing
- Hybrid Routing
- Static Routing
Static routing is generally more cost-effective and simpler to manage for small networks with stable topologies as it involves manually configuring routes.
Which device is used to connect multiple devices within one local network, often used in homes and small businesses?
- Hub
- Modem
- Router
- Switch
A switch is used to connect multiple devices within one local network, commonly used in homes and small businesses.
When a network experiences an issue immediately after a configuration change, what troubleshooting principle should the technician follow first?
- Roll back the configuration change
- Implement additional security measures
- Increase network bandwidth
- Reboot the affected devices
In troubleshooting issues after a configuration change, the technician should first consider rolling back the configuration change to the previous state and observe the impact.
In a large data center, network engineers need to rapidly deploy changes across thousands of devices. What network automation strategy should they adopt to manage this effectively?
- Orchestration
- Configuration Management
- Continuous Integration/Continuous Deployment (CI/CD)
- Scripting
CI/CD is a strategy that allows rapid deployment and changes across a large number of devices in a data center.
Which QoS feature is used to manage congestion by controlling the rate at which packets are sent into the network?
- Traffic shaping
- Packet filtering
- Congestion avoidance
- Link aggregation
Traffic shaping is a QoS feature used to manage congestion by controlling the rate at which packets are sent into the network, preventing network congestion.
