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.
What kind of cable is best suited for network environments where electromagnetic interference is a concern?
- Coaxial Cable
- Fiber Optic Cable
- HDMI Cable
- Twisted Pair
Fiber optic cables are best suited for network environments where electromagnetic interference is a concern because they are immune to such interference.

A Bus topology is known for its simplicity and is commonly used for small local area networks.
What is a potential drawback of improper route summarization in a network?
- Enhanced network security
- Improved scalability
- Increased routing table size
- Reduced network latency
Improper route summarization can lead to an increased routing table size, negatively impacting network performance and scalability.
For a data center requiring high levels of redundancy and interconnectedness between all systems, which topology would provide the optimal structure?
- Bus
- Mesh
- Ring
- Star
In a data center with high redundancy requirements, a mesh topology is optimal as it provides interconnectedness between all systems, minimizing points of failure.
Which basic tool is commonly used to verify connectivity between two network devices?
- Multimeter
- Protocol Analyzer
- Cable Tester
- Ping
The basic tool commonly used to verify connectivity between two network devices is the "Ping" tool, which sends a test message to check if a device is reachable.
