Question 3 (SO 5, AC 1)
a) Explain the importance of backing when using Local Area Computer Network.
b) Describe the rules of thumb when developing a backup plan for your Local Area Computer
Network.
Question 1:
a) The performance of a local area computer network must be monitored for several reasons:
- To ensure optimal performance and efficiency of the network.
- To identify and address any bottlenecks or issues that may be affecting network performance.
- To monitor network usage and identify any unauthorized or suspicious activity.
- To ensure that network resources are being used effectively and efficiently.
- To proactively address any potential issues before they escalate into major problems.
b) Some techniques used to collect network performance data include:
- Network monitoring tools that provide real-time data on network traffic, bandwidth utilization, and performance metrics.
- Packet capturing tools that capture and analyze network packets to identify any issues or anomalies.
- SNMP (Simple Network Management Protocol) monitoring to collect data from network devices such as switches, routers, and servers.
- Performance testing tools to simulate network traffic and measure network performance under different conditions.
Question 2:
a) Sources or causes of user, fileserver, and performance problems with local area computer networks may include:
- User errors or mistakes in network configuration.
- Fileserver issues such as disk space limitations, hardware failures, or software errors.
- Network congestion or bandwidth limitations.
- Malware or security breaches.
- Hardware failures or malfunctions.
b) The recommended procedure in the IT industry for resolving local area computer network problems includes:
- Identifying and isolating the root cause of the problem through thorough troubleshooting and analysis.
- Implementing temporary solutions if needed to restore network functionality.
- Implementing permanent solutions to address the underlying issue and prevent future occurrences.
- Documenting the problem and solution for future reference.
- Testing the network to ensure the problem has been resolved.
Question 3:
a) The importance of backing up data when using a Local Area Computer Network includes:
- Protection against data loss due to hardware failures, human error, malware, or other unforeseen events.
- Ensure business continuity in the event of a disaster.
- Compliance with data protection regulations and requirements.
- Peace of mind knowing that data is securely backed up and can be restored if needed.
b) Rules of thumb when developing a backup plan for a Local Area Computer Network include:
- Regularly scheduled backups of all critical data and files.
- Storing backups in a secure and offsite location to protect against physical damage or theft.
- Testing backups periodically to ensure they are functional and can be restored when needed.
- Implementing a redundant backup system to ensure data is always available, even in the event of a backup failure.
- Documenting the backup plan and procedures for easy reference and implementation.
