The best immediate actions to prevent unauthorized server access are to stop all unneeded services and block the ports on the firewall. Stopping unneeded services reduces the attack surface of the server by eliminating potential entry points for attackers. For example, if the server is not functioning as a web server, there is no need to run a web service on port 80. Blocking ports on the firewall prevents unauthorized network traffic from reaching the server. For example, if port 80 is not needed for any legitimate purpose, it can be blocked on the firewall to deny any connection attempts on that port.

The server installation method that would optimize server resources is core. Core is a minimal installation option that is available for some operating systems, such as Windows Server and Linux. Core installs only the essential components and features of the operating system, without any graphical user interface (GUI) or other unnecessary services or applications. Core reduces the disk footprint, memory usage, CPU consumption, and attack surface of the server, making it more efficient and secure. Core can be managed remotely using command-line tools, PowerShell, or GUI tools.

A tower server is a type of server architecture that is best suited to minimize cost when deploying a single server to monitor and record the security cameras at a remote site. A tower server is a standalone server that has a similar form factor and design as a desktop computer. It does not require any special mounting equipment or rack space and can be placed on or under a desk or table. A tower server is suitable for small businesses or remote offices that need only one or few servers for basic tasks such as file sharing, print serving, or security monitoring. A tower server is usually cheaper and easier to maintain than other types of servers, but it may have lower performance, scalability, and redundancy features. A virtual server is a type of server architecture that involves creating and running one or more virtual machines on a physical host using a hypervisor such as Hyper-V or VMware. A virtual server can reduce hardware costs and improve flexibility and efficiency, but it requires additional software licenses and management tools. A blade server is a type of server architecture that involves inserting multiple thin servers called blades into a chassis that provides power, cooling, network, and management features. A blade server can improve performance, density, and scalability, but it requires more initial investment and specialized equipment. A rack mount server is a type of server architecture that involves mounting one or more servers into standardized frames called racks that provide power, cooling, network, and security features

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.

The administrator should identify the runaway process or processes that are causing high load average on the server. Load average is a metric that indicates how many processes are either running on or waiting for the CPU at any given time. A high load average means that there are more processes than available CPU cores, resulting in poor performance and slow response time. A runaway process is a process that consumes excessive CPU resources without terminating or releasing them. A runaway process can be caused by various factors, such as programming errors, infinite loops, memory leaks, etc. To identify a runaway process, the administrator can use tools such as top, ps, or htop to monitor CPU usage and process status. To stop a runaway process, the administrator can use commands such as kill, pkill, or killall to send signals to terminate it.

The best backup methods to use to support the management’s priorities are differential and incremental. A backup is a process of copying data from a source to a destination for the purpose of restoring it in case of data loss or corruption. There are different types of backup methods that vary in terms of speed, efficiency, and storage requirements. Differential and incremental backups are two types of partial backups that only copy the data that has changed since the last full backup. A full backup is a type of backup that copies all the data from the source to the destination. A full backup provides the most complete and reliable restore option, but it also takes the longest time and requires the most storage space. A differential backup copies only the data that has changed since the last full backup. A differential backup provides a faster restore option than an incremental backup, but it also takes more time and requires more storage space than an incremental backup. An incremental backup copies only the data that has changed since the last backup, whether it was a full or an incremental backup. An incremental backup provides the fastest and most efficient backup option, but it also requires multiple backups to restore the data completely.

This is the most likely reason why the fans in that server are operating at full speed while the ambient temperature in the room is normal and the other servers in the rack are not experiencing this behavior. A fan failure is a situation where one or more fans in a server stop working or malfunction due to wear and tear, dust, or other factors. This can cause overheating and performance issues on the server. To prevent this, most servers have a fan redundancy feature that allows the other fans to increase their speed and airflow to compensate for the failed fan and maintain a safe temperature level. The server is not likely to be in the process of shutting down, as this would not cause the fans to run at high speeds. An incorrect fan size is not likely to be inserted into the server, as most fans are standardized and compatible with the server chassis and motherboard. The server is not likely to be utilizing more memory than the other servers, as this would not cause a significant increase in temperature or fan speed.

Out-of-band console is a tool that can be used to command a remote shutdown of a physical Linux server. Out-of-band console is a method of accessing a server’s console through a dedicated management port or device that does not rely on the server’s operating system or network connection. Out-of-band console can be used to power cycle, reboot, update firmware, monitor performance, and perform other tasks remotely even if the server is unresponsive or offline. Crash cart is a mobile unit that contains a keyboard, monitor, mouse, and other tools that can be used to troubleshoot a server on-site, but it requires physical access to the server. IP KVM (Internet Protocol Keyboard Video Mouse) switch is a hardware device that allows remote access to multiple servers using a web browser or a client software, but it requires network connectivity and may not work if the SSH connection is lost. RDP (Remote Desktop Protocol) is a protocol that allows remote access to a Windows server’s graphical user interface, but it does not work on Linux servers and requires network connectivity.
