You are building a virtualization environment to host several secured Linux distributions as VMs. The VMs need to have access to the local corporate network and communicate with the host operating system, the other VMs, and the internal network clients. Still, they should not have access to the internet. Which of the following types of network connections should you configure for each VM?

• Private

• External

• Localhost

• Internal

Answer explanation

The 'Internal' network connection allows VMs to communicate with each other and the host while restricting internet access. This meets the requirement of having local network access without exposing the VMs to the internet.

To do this, they need to choose the right technology for their displays. Which technology should Troytec Consulting recommend to allow for the thinnest laptop displays?

• OLED

• LCD

• LED

• IPS

Answer explanation

OLED technology is ideal for creating the thinnest laptop displays because it does not require a backlight, allowing for a slimmer profile compared to LCD and LED technologies.

You have decided that you wanted to install a second operating system on your computer. After installing the OS and rebooting the computer, you see the "Operating System Not Found" error on your display. You verify that the boot.ini file is configured properly, but the error still appears. What is MOST likely causing this error?

• The MBR boot loader was installed accidentally

• Windows Startup services are not properly running

• An unsupported version of Linux is installed

• An incompatible partition is marked as active

Answer explanation

The "Operating System Not Found" error is most likely due to an incompatible partition being marked as active. This means the system is trying to boot from a partition that does not contain a valid OS.

You just heard of a new ransomware attack that has been rapidly spreading across the internet that takes advantage of a vulnerability in the Windows SMB protocol.

Which of the following ports should you add to your blocklist?

• 445

• 80

• 22

• 443

The SMB protocol uses port 445 for file sharing and network services. Blocking this port will help prevent the ransomware attack that exploits vulnerabilities in SMB, making it the correct choice.

Unfortunately, your friend never gave you the password for this laptop. Which of the following actions should you take to resolve this issue and get past this password screen?

• Disconnect the hard drive from the motherboard for a few minutes, reconnect it, and then power on the laptop

• Remove the CMOS battery, wait a few minutes, reinsert the battery, then power on the laptop

• Remove the laptop's battery, wait a few minutes, reinsert the battery, and then power on the laptop

• Press and hold the power button down for a few minutes, attempt to power on the laptop

Answer explanation

Removing the CMOS battery resets the BIOS settings, which can help bypass the password screen. This method is effective for clearing forgotten passwords, unlike the other options that do not address the password issue directly.
