When upgraded computers are not able to obtain an IP address, the issue often lies in the network configuration. Here’s a

Option A: The switch is only providing IPv6 addresses.This is unlikely because if the switch were providing IPv6 addresses, the devices would still receive an IP address, albeit an IPv6 one. The issue described indicates no IP address is being obtained at all.

Option B: The OS must be updated to be compatible with the imaging software.This option is unrelated to obtaining an IP address. Compatibility with imaging software would not prevent the devices from getting an IP address.

Option C: The switch has port security enabled.Correct Answer. Port security on a switch restricts access based on MAC addresses. If the MAC addresses of the upgraded computers are not recognized or have not been added to the allowed list, the switch will not provide network access, resulting in the computers not obtaining an IP address.

A .vbs file is a Virtual Basic script written in the VBScript scripting language. It contains code that can be executed within Windows via the Windows-based script host (Wscript.exe), to perform certain admin and processing functions1. Cscript.exe is a command-line version of the Windows Script Host that provides command-line options for setting script properties. Therefore, cscript.exe is most likely used to run .vbs files on Windows devices.

The most likely cause of the issue of having different hash values for a downloaded security tool is a modified file. A hash value is a unique and fixed-length string that is generated from an algorithm that processes data or files. A hash value can be used to verify the integrity and authenticity of data or files by comparing it with a known or expected value. If the hash values do not match, it means that the data or file has been altered or corrupted in some way. A modified file may result from intentional or unintentional changes, such as editing, encryption, compression or malware infection. Private-browsing mode is a feature that allows users to browse the web without storing any browsing history, cookies or cache on their browser. Private-browsing mode does not affect the hash value of a downloaded file but only how the browser handles user data. Invalid certificate is an error that occurs when a website or a server does not have a valid or trusted digital certificate that proves its identity and secures its communication. Invalid certificate does not affect the hash value of a downloaded file but only how the browser verifies the website or server’s credibility. Browser cache is a temporary storage that stores copies of web pages, images and other content that users have visited on their browser.
