The IP address that best fits this scenario is 216.176.128.10. This is a public IP address that belongs to a range of addresses that are assigned and registered by an Internet service provider (ISP) and can be accessed from anywhere on the Internet. The company has a public range of IP addresses and uses them internally, which means that they do not use private IP addresses or network address translation (NAT) to communicate within their network.

An incremental backup is a backup method that only backs up the files that have changed since the last backup, whether it was a full or an incremental backup. An incremental backup can save disk space and time, as it only copies the new or modified data. An incremental backup can also improve the RTO (Recovery Time Objective), which is the maximum acceptable time to restore data after a disaster. This is because an incremental backup can restore data faster than a full or a differential backup, as it only needs to apply the latest changes to the previous backup1.

Incremental backup is a type of backup that only backs up the files that have changed since the last backup, whether it was a full or an incremental backup. Incremental backup resets the archive bit each time it is run, which means it clears the flag that indicates whether or not the file has been backed up. Incremental backup can save time and space compared to full backup, but it requires more time and resources to restore data from multiple backups.References: https://www.comptia.org/training/resources/exam-objectives/comptia-server-sk0-005-exam-objectives (Objective 3.1)

PowerShell is a scripting language and a command-line shell that uses commands that start with sec- to perform security-related tasks. For example, sec-edit is a command that edits security policies, sec-logon is a command that manages logon sessions, and sec-policy is a command that applies security templates.

A synthetic full backup is a type of backup that copies changed data from a server and then combines the backups on the backup target. This way, the backup target always has a full backup of the server, without requiring a full backup to be performed over the network. A synthetic full backup reduces the network bandwidth and time required for backups, while also simplifying the restoration process1

This is the most likely cause of preventing the users from accessing the application server because a VLAN is a logical segmentation of a network that isolates traffic based on certain criteria. If the human resources department and the application server are on different VLANs, they will not be able to communicate with each other unless there is a router or a switch that can route between VLANs.References:https://www.cisco.com/c/en/us/support/docs/lan-switching/inter-vlan-routing/41860-howto-L3-intervlanrouting.html

The audit.log file is a file that records security-related events on a Linux server, such as user login, file access, and system commands. The logrotate utility is a tool that rotates, compresses, and deletes old log files based on certain criteria, such as size, time, or frequency. To decrease the number of times the log rotates without losing any information, the administrator should increase the audit.log file size in the appropriate configuration file, such as /etc/logrotate.conf or /etc/logrotate.d/auditd.

netstat is a command-line tool that displays network connections, routing tables, interface statistics, and more. The -a option shows all listening and non-listening sockets on the server. This can help check the open ports on a server and identify any unwanted or malicious connections.References:https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/netstat

Password length is the first password policy that the administrator should implement to help mitigate the chance of a successful brute-force attack. A brute-force attack is a method of guessing passwords by trying all possible combinations of characters untilthe correct one is found. The longer the password, the more combinations there are, and the more time and resources it takes to crack it. Therefore, password length is a key factor in password strength and security.

A crash cart is a mobile device that consists of a monitor, a keyboard, a mouse, and a network connection. It can be used to access a physical server that is not responding to remote management software or does not have out-of-band management cards configured. The technician can connect the crash cart to the server using a VGA or HDMI cable and troubleshoot the server locally. Verified References: [Crash cart], [Out-of-band management]
