An IDRAC (Integrated Dell Remote Access Controller) is a tool that can be used to command a remote shutdown of a physical Linux server. An IDRAC is a hardware device that provides out-of-band management for Dell servers. It allows the technician to access the server’s console, power cycle, reboot, or shut down the server remotely using a web interface or a command-line interface. An IDRAC does not depend on the operating system or network connectivity of the server. A virtual serial console is a tool that can be used to access a remote virtual machine’s console using a serial port connection. A KVM (Keyboard, Video, Mouse) switch is a device that allows the technician to switch between different computer sources using the same keyboard, monitor, and mouse.

Maintenance and support is a type of license that would most likely include vendor assistance. Maintenance and support is a contract that defines the level and scope of service and assistance that a vendor provides to a customer for using their software product. Maintenance and support may include technical support, bug fixes, patches, updates, upgrades, documentation, training, and other benefits. Maintenance and support licenses usually have an annual fee based on the number of users or devices covered by the contract. Open-source is a type of license that allows free access to the source code and modification and distribution of the software product, but does not guarantee vendor assistance. Version compatibility is not a type of license, but a feature that ensures software products can work with different versions of operating systems or other software products. Subscription is a type of license that allows access to software products for a limited period of time based on recurring payments, but does not necessarily include vendor assistance.

The best way to limit an attacker from exploiting a zero-day vulnerability that is impacting a service enabled on a server OS is to install the latest patches. Patches are updates that fix bugs, improve security, or add features to software. Installing patches can help prevent attackers from exploiting known vulnerabilities that have been fixed by the software vendor. A zero-day vulnerability is a vulnerability that is unknown to the vendor or the public until it is exploited by an attacker. Therefore, installing patches as soon as they are available can reduce the window of opportunity for attackers to exploit zero-day vulnerabilities.
