When disposing of e-waste, it is important to ensure that the data on the equipment is securely destroyed and that the disposal process complies with environmental regulations.
* Non-disclosure agreement: Relates to confidentiality, not disposal.
* Certification of destruction: The correct document verifying that the equipment has been disposed of in accordance with regulations and standards, ensuring data is irretrievably destroyed.
* Low-level formatting: A method to wipe data but does not guarantee compliance with e-waste disposal regulations.
* Shredding/drilling: Physical destruction methods that might be used, but certification of destruction is the documentation needed.

Using bootable antivirus media to scan the system is an effective method for removing a persistent virus.
Booting from external antivirus media allows the system to scan for and remove malware without the infected operating system running, which can prevent the virus from hiding or resisting removal efforts that might occur within the active OS environment.

Journaling is a feature that helps maintain the integrity of the filesystem by keeping a record of changes not yet committed to the main file system. This feature is supported by various filesystems, but not all.
* Option A: NTFSNTFS (New Technology File System) is a filesystem used by Windows that supports journaling. This makes it resilient to corruption from unexpected shutdowns or crashes by keeping a log of file changes.
* Option B: exFATexFAT (Extended File Allocation Table) does not support journaling. It is optimized for flash drives and large files but lacks advanced features like journaling.
* Option C: HFSHFS (Hierarchical File System) is an older filesystem used by Apple. HFS+ (also known as Mac OS Extended) supports journaling, but HFS itself does not.
* Option D: ext2ext2 (Second Extended File System) is a filesystem for Linux that does not support journaling. Its successor, ext3, introduced journaling.

Before making any changes to the system, it is important to assess the risks associated with the change and determine whether it is worth implementing. Risk analysis involves identifying potential risks, assessing their likelihood and impact, and determining what steps can be taken to mitigate them. It is important to perform this step before making any changes, as this allows the administrator to make an informed decision about whether or not the change should be implemented. Once the risks have been assessed and the administrator has decided to go ahead with the change, the next step is to implement the deployment.
