10.2 Sample Exam Questions Explained

Key Concepts

Understanding the sample exam questions for the MikroTik Certified Wireless Engineer (MTCWE) involves grasping several key concepts:

• Wireless Network Configuration
• Security Settings
• Performance Tuning
• Troubleshooting Techniques
• Interoperability
• QoS Implementation
• Monitoring and Reporting
• Scalability
• Integration with Other Networks
• Advanced Features

Wireless Network Configuration

Wireless Network Configuration involves setting up and managing the wireless interfaces on MikroTik devices. This includes configuring SSID, channel, bandwidth, and transmission power. Proper configuration ensures optimal wireless performance and coverage.

Example: Think of wireless interface configuration as setting up a radio station. By tuning the frequency (channel), adjusting the volume (transmission power), and naming the station (SSID), you ensure that listeners (clients) can clearly hear the broadcast (signal).

Security Settings

Security Settings involve configuring measures to protect the wireless network from unauthorized access and attacks. This includes setting up encryption protocols (e.g., WPA3), implementing access control lists (ACLs), and regularly updating security policies. Strong security settings ensure the integrity and confidentiality of the network.

Example: Think of security settings as fortifying a castle. By building strong walls (encryption), setting up guards (ACLs), and regularly maintaining the fortifications (security policies), you ensure that the castle (network) is secure from intruders (unauthorized access).

Performance Tuning

Performance Tuning involves optimizing the wireless network to ensure it operates efficiently. This includes adjusting channel settings, increasing transmission power, and upgrading hardware. Proper tuning ensures that the network can handle the expected load and provide consistent performance.

Example: Consider performance tuning as fine-tuning a race car. By adjusting the engine (channel settings), increasing the horsepower (transmission power), and upgrading the tires (hardware), you ensure the car (network) performs at its best during the race (high traffic).

Troubleshooting Techniques

Troubleshooting Techniques involve identifying and resolving issues that may arise in the wireless network. This includes using tools like MikroTik's Wireless Monitoring to track performance metrics, identify anomalies, and troubleshoot problems. Effective troubleshooting ensures network reliability and performance.

Example: Think of troubleshooting as a detective solving a mystery. By collecting clues (performance metrics), identifying suspects (anomalies), and following leads (troubleshooting steps), the detective (network administrator) can solve the case (resolve issues) and ensure justice (network stability).

Interoperability

Interoperability involves ensuring that MikroTik wireless devices can work seamlessly with other manufacturers' devices. This includes configuring protocols and settings to ensure compatibility and smooth communication between different devices.

Example: Think of interoperability as a universal power adapter that works with various electronic devices from different brands. The adapter (MikroTik devices) ensures all devices (third-party devices) can connect and function properly.

QoS Implementation

QoS (Quality of Service) Implementation involves setting up policies to prioritize network traffic based on its importance. This includes classifying traffic, managing bandwidth, and ensuring critical applications receive the necessary resources. Proper QoS implementation ensures optimal network performance.

Example: Consider QoS implementation as managing a highway. By designating specific lanes for emergency vehicles (high-priority traffic) and regular cars (low-priority traffic), you ensure that emergency vehicles can reach their destination quickly, while regular traffic flows smoothly.

Monitoring and Reporting

Monitoring and Reporting involve continuously observing the wireless network to detect and resolve issues. This includes using tools like MikroTik's Wireless Monitoring to track performance metrics, identify anomalies, and troubleshoot problems. Effective monitoring and reporting ensure network reliability and performance.

Example: Consider monitoring and reporting as a security guard who continuously patrols a building. By keeping an eye on all activities (performance metrics) and reporting any unusual behavior (anomalies), the guard ensures the building remains secure and any issues are promptly addressed.

Scalability

Scalability involves designing the network to accommodate growth and future technological advancements. This includes selecting scalable hardware, implementing flexible configurations, and planning for future upgrades to ensure the network remains efficient and reliable.

Example: Think of scalability as building a house with room to expand. The initial design (network configuration) allows for additional rooms (network growth) and modern amenities (future upgrades), ensuring the house (network) remains comfortable and functional over time.

Integration with Other Networks

Integration with Other Networks involves combining MikroTik wireless networks with other network segments to create a unified network. This includes configuring MikroTik devices to handle both wireless and wired connections, ensuring smooth data flow between the two segments.

Example: Think of a wireless and wired network integration as a hybrid car that combines an electric motor (wireless) with a gasoline engine (wired) to provide efficient and reliable transportation.

Advanced Features

Advanced Features involve utilizing the advanced capabilities of MikroTik devices to enhance network performance and security. This includes configuring VPNs, implementing advanced routing protocols, and using advanced monitoring tools. Proper use of advanced features ensures a robust and secure network.

Example: Consider advanced features as the advanced settings on a high-end camera. By adjusting the settings (configuring advanced features), you can capture professional-quality photos (ensure robust network performance) and protect the camera (network) from unauthorized access.
