Chain of custody is a process that documents how evidence is collected, handled, stored and transferred during a cybercrime investigation. It ensures that the evidence is authentic, reliable and admissible in court. If the chain of custody is violated during an investigation, it can compromise the integrity of the evidence and lead to the case being dismissed. Open-source software, EULA (end-user license agreement) and AUP (acceptable use policy) are not related to cybercrime investigations or evidence handling. Verified References:

Detailed Explanation with Core 2 References:Incremental backups only save changes made since the last backup, significantly reducing storage space requirements compared to full backups. This approach is consistent with the Core 2 objective of understanding various backup methods and their space requirements (Core 2 Objective 4.3).

The Linux command used to install an application is sudo. The sudo command allows users to run programs with the security privileges of another user, such as the root user. This is necessary to install applications because it requires administrative privileges1

Redeeming the included activation key card for a product key is the correct way to apply a Windows 10 Pro license to a computer that has Windows 10 Home installed. The activation key card is a physical or digital card that contains a 25-digit code that can be used to activate Windows 10 Pro online or by phone. Copying the windows.lie file, inserting a Windows USB hardware dongle and activating with the digital license are not valid methods of applying a Windows 10 Pro license.

The ipconfig /all output shows the following:
IPv4 Address............ 192.168.0.74Subnet Mask............. 255.255.255.255Default Gateway......... 192.168.0.1 The issue with the subnet mask being set to 255.255.255.255 is that it specifies a single host subnet, meaning the device cannot communicate with other devices on the network or access the internet. The correct subnet mask for a typical home network should be:
* Subnet mask of 255.255.255.0: This allows for communication within the same local network (192.168.0.0/24).
* Default gateway 192.168.0.1: Correct, this is the typical address for the router.
* IPv4 Address 192.168.0.74: Correct, within the correct subnet range.
Changing the subnet mask to 255.255.255.0 will resolve the connectivity issue.
