Detailed Explanation with Core 2 References:The ipconfig command displays the IP address, subnet mask, and default gateway for all network adapters in a Windows computer. This output specifically shows details about an Ethernet adapter, which is directly tied to ipconfig. According to Core 2, understanding command-line tools like ipconfig is essential for network troubleshooting (Core 2 Objective 1.2)​.

Disposing of SSDs (Solid State Drives) containing sensitive data requires methods that ensure the data cannot be recovered. SSDs store data on flash memory, which makes traditional data destruction methods like degaussing ineffective, as degaussing relies on demagnetizing the magnetic media found in traditional hard drives.

Incineration: This method ensures the complete destruction of the SSD by burning it at high temperatures. This process is effective as it physically destroys the flash memory chips, making data recovery impossible.

Shredding: Shredding involves physically breaking the SSD into small pieces. Specialized shredding machines designed for electronic media can cut the SSD into pieces small enough to render the data unrecoverable.

Other listed options such as Degaussing (A) is ineffective on SSDs because they don't use magnetic storage. Simple Deletion (B) and Formatting (E) are not secure methods for data destruction as the data can potentially be recovered using specialized software. Recycling (D) is environmentally friendly but does not guarantee data destruction if the drive is not physically destroyed first.

For ensuring data protection against local natural disasters and hardware failures, the best approach is to use an off-site solution that provides redundancy and is resilient to local disruptions.

Using an agent-based cloud backup solution: This method involves backing up data to a remote cloud server, providing protection against local disasters like floods, fires, or hardware failures since the data is stored off-site and can be accessed from anywhere.

Implementing a grandfather-father-son backup rotation: While effective for managing local backups, this method typically involves physical media which could still be vulnerable to local disasters.

Automating backups to a local network share: This keeps the backups within the same physical location, making them susceptible to local disasters.

Saving files manually to an external drive: This method is prone to human error and doesn't provide automated or off-site protection.

Rebooting the computer into safe mode (Option B) limits the processes and services that run, which can help in isolating and removing persistent malware that might be hiding in normal mode. Safe mode provides a cleaner environment to troubleshoot and remove malware.

Restoring from a backup (Option A) may work but should be considered after attempts to clean the infection.

Purchasing a new endpoint protection tool (Option C) is unnecessary at this stage since existing tools can be run in safe mode.

Using system recovery (Option D) could potentially remove the infection, but it's a more drastic step that may not be necessary yet.

When a user is unable to access shared drives from a company-issued laptop while working from home, the likely requirement is:

VPN (Virtual Private Network): A VPN allows secure access to the company’s network from a remote location. Without a VPN connection, the user cannot access network resources such as shared drives.

IPv6: Involves IP addressing and is not directly related to accessing shared drives.

IPS (Intrusion Prevention System): Provides network security but does not facilitate access to shared drives.

DNS: Manages domain name resolution and is not typically the issue when specific shared drives are inaccessible.

Restarting services can resolve issues with web applications without requiring a full server reboot, which aligns with the company policy.

Restart services: Likely to resolve issues with the web application by refreshing the necessary services.

Roll back Windows updates: Unnecessary if the issue is with the application services.

Perform a Windows repair: More disruptive and not typically needed for application service issues.

Add RAM to the server: Would require a reboot and is not immediately necessary for troubleshooting application issues.

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.

Verifying warranty status with the vendor is the most logical next step in the remediation process after determining that a motherboard has failed. A warranty is a guarantee from the vendor that covers the repair or replacement of defective or faulty products within a specified period of time. Verifying warranty status with the vendor can help the technician determine if the motherboard is eligible for warranty service and what steps to take to obtain it. Escalating the issue to Tier 2, replacing the motherboard, and purchasing another PC are not the most logical next steps in the remediation process.
