The administrator should use SCP to transfer log files from a Linux server to a Windows workstation. SCP (Secure Copy Protocol) is a protocol that allows secure file transfer between two devices using SSH (Secure Shell) encryption. SCP can transfer files between different operating systems, such as Linux and Windows, as long as both devices have an SSH client installed. SCP can also preserve file attributes, such as permissions and timestamps, during the transfer.

The IP address/default gateway combination that the administrator should have used for the new server is IP address: 192.168.10.2/24 and Default gateway: 192.168.10.1. The IP address and the default gateway of a device must be in the same subnet to communicate with each other. A subnet is a logical division of a network that allows devices to share a common prefix of their IP addresses. The subnet mask determines how many bits of the IP address are used for the network prefix and how many bits are used for the host identifier. A /24 subnet mask means that the first 24 bits of the IP address are used for the network prefix and the last 8 bits are used for the host identifier. Therefore, any IP address that has the same first 24 bits as the default gateway belongs to the same subnet. In this case, the default gateway has an IP address of 192.168.10.1/24, which means that any IP address that starts with 192.168.10.x/24 belongs to the same subnet. The new server has an IP address of 192.168.1.1/24, which does not match the first 24 bits of the default gateway, so it belongs to a different subnet and cannot communicate with the default gateway. To fix this issue, the administrator should change the IP address of the new server to an unused IP address that starts with 192.168.10.x/24, such as 192.168.10.2/24.

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. A crash cart is a mobile unit that contains a keyboard, monitor, mouse, and other tools that can be connected to a physical server for troubleshooting purposes.

The next thing that the technician should perform is to enable the port on the server. A port is a logical endpoint that identifies a specific service or application on a network device. A port can be enabled or disabled depending on whether the service or application is running or not. If a port is disabled on a server, it means that the server cannot send or receive any network traffic on that port, which can prevent communication with other devices or services that use that port. In this case, if port 389 is disabled on the server, it means that the server cannot use LDAP to access or modify directory services over a network. To resolve this issue, the technician should enable port 389 on the server using commands such as netsh or iptables.
