RTO stands for Recovery Time Objective and it is a metric that defines the maximum acceptable amount of time that a system or service can be unavailable after a disaster or disruption. RTO is part of the business continuity planning and disaster recovery planning processes. RTO ensures a guarantee of the amount of time it will take to restore a downed service by setting a target or goal for recovery. RTO can vary depending on the criticality and priority of the service.

This is the least destructive method of resetting the administrator password because it does not require modifying any files or reinstalling the OS. It only requires changing the boot parameters temporarily and running a command to change the password. Reference:

This is the most likely cause of the issue because the keyboard LED flash indicates a POST error code. If the display card is not initialized, the system cannot show any error messages on the screen and will stop booting. Reference: https://www.computerhope.com/beep.htm#04

This is the best definition of overprovisioning in a virtual server environment because it means allocating more CPU, memory, disk, or network resources to the virtual machines than what is actually available on the physical host. This can lead to performance issues and resource contention.

This is the most likely misconfigured setting because the default gateway is the router that connects the local network to other networks. If the default gateway is incorrect, the server will not be able to communicate with remote users or devices outside its own subnet. Reference:

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.

This is the most likely misconfigured setting because DNS is the service that resolves hostnames to IP addresses and vice versa. If the DNS server is incorrect or unreachable, the administrator will not be able to log on to the server with a domain account because the server will not be able to authenticate with the domain controller. Reference: https://docs.microsoft.com/enus/ troubleshoot/windows-server/networking/dns-troubleshooting

This is the best solution to prevent unauthorized files from being copied to the server via FTP because anonymous access allows anyone to log in to the FTP server without providing a username or password. Disabling anonymous access will require users to authenticate with valid credentials before accessing the FTP server.

This is the most likely licensing type that will be used because volume licensing allows a single license key to be used for multiple installations of a software product. Volume licensing is typically used by organizations that need to deploy software to a large number of devices or users. Reference:
