Network diagnostic utility How it can be used for troubleshooting a. Event viewer How event viewer can be used for troubleshooting? b. Network monitor How network monitor can be used for troubleshooting? c. Performance console How performance console can be used for troubleshooting?

Question 11 Explain how an operating system rescue environment can resolve operating issues. The purpose of an operating system rescue environment is to be able to automatically run in the event of a boot failure and to automatically repair the issue. Question 12 Explain how to use operating system help and support utilities for troubleshooting server issues. There are a number of troubleshooting tools and techniques that can be used to diagnose and correct server problems. These will be dependent upon the type of server installed and make and model. As an example, Microsoft Server utilities include:  Event viewer  Network monitor

Question 17 Explain the purpose of network directory services and an outline of the process for network services directory configuration. The purpose of network directory services is to provide a map and a naming protocol that enables the devices and users on the network to connect. The two most common network directories are LDAP and Active Directory. Configuring these services requires the administrator to identify the device or service by its server address, specify the server port, enter the domain name of the server, create or authorise the username and the password. Question 18 Explain best practice for implementing backup and recovery procedures The 3,2,1 rule for backup is a great file backup strategy. The 3-2-1 rule is a widely recommended backup strategy that provides a strong level of data protection. It emphasizes redundancy and off-site storage to safeguard against various threats. The rule is as follows: 1. Have at least three copies of your data: This means creating and maintaining three separate copies of your important files or data. The original data plus two additional copies. By having multiple copies, you increase the chances of data recovery in case of data loss. 2. Store the copies on two different types of media: Use different storage media for your backup copies. For example, you can have one copy on your computer's internal hard drive, another on an external hard drive or network-attached storage (NAS), and the third on cloud storage. This protects against failures or damage to a single type of media. 3. Keep one copy off-site: Ensure that at least one backup copy is stored off-site, preferably in a different physical location. This protects against events like theft, fire, flood, or other disasters that could affect your primary location. Off-site backups can be stored in cloud storage, at a remote data center, or in a different physical location within your organization. The 3-2-1 rule provides a robust backup strategy that combines redundancy, media diversity, and geographic separation. It helps guard against various risks such as hardware failures, accidental deletions, malware attacks, and site-level disasters. Following this rule significantly increases the chances of recovering your data in case of an unfortunate event. However, it's important to regularly test and validate your backups, ensure proper security measures are in place, and consider the specific needs and compliance requirements of your organization when implementing a backup strategy.

Scheduling a task is an efficient way to automate regular tasks such as a system back up that takes place overnight when an office is empty. Automating a task avoids the human error of forgetting to do it. Task scheduling utilities are software tools that allow you to automate and schedule the execution of tasks or processes on a computer system. These utilities offer several benefits, including increased productivity, improved efficiency, and better resource utilization.
